Audacity 3.6.0
Major changes
Master effects
Audacity now features master effects. Master effects are effects which apply to the entire project at once. More information can be found at Using master effects & realtime effects.
New compressor and limiter
A new compressor and limiter has been added, replacing the previous versions. A gain reduction history has been added to these effects when they're used as a realtime effect.
Factory Presets suitable for a wide range of use cases for these effects have been provided by Vladislav Isaev and Marek Iwaszkiewicz, available via the Presets & Settings button.
New themes
Audacity now features new and improved dark and light themes. You can switch between themes via Preferences -> Interface. The theme previously used still is around as the Classic theme, and themes even older than that can be optionally installed as custom themes from here.
Updated instructions on creating custom themes can be found here.
Increased performance
Audacity is now quite a bit snappier than before, especially when working on larger projects and on larger screens.
Other changes
Added FFmpeg 7 support.
You now can paste audio files into Audacity using Ctrl+V.
Alternative waveform colors are now themeable by custom themes.
Removed the track name overlay preference and the "blend themes" preference.
Scripting: Added GetInfo: Type=Selection. (Thanks, Jonatã Bolzan Loss!)
Added an Extras > Export > Export Selected Audio option.
Import Raw: Added support for offsets larger than 2 GB.
Redesigned the "what's new" dialog.
Added an option to the View menu to show/hide RMS in waveforms.

Audacity 3.5.1
This is a hotfix release. It fixes the following bugs:
#6322 Fixed a crash on launch on macOS 11 and older.
#6324 Fixed the update notification looking for alpha versions instead of release versions.
#6321 Fixed a freeze when using macros on multiple files.
Audacity 3.5.0
Audacity 3.5 adds cloud saving, beat detection, pitch shifting and more.
Major changes
Cloud project saving
We've introduced a new cloud-saving feature that allows you to save your Audacity projects to audio.com. This allows you to work from any device, share & collaborate with others and restore previous versions if something went wrong.
Automatic tempo detection
Audacity can now automatically detect the tempo of imported loops, and adjust them to be in tempo.
Tempo detection is done via both audio analysis and metadata checking. If you want to prepare your loop for automatic tempo detection without relying on audio analysis, both acidizer tempo tags or simply writing "123 bpm" anywhere into the filename work.
Automatic tempo detection can be turned off via Preferences -> Import/Export.
Pitch shifting
You now can non-destructively change the pitch of a clip by holding Alt and pressing the Up and Down arrow keys. Alternatively, you can click on the overflow menu (...) and select "Pitch and speed...". When changing the pitch this way, an arrow in the UI indicates how much you've shifted it.
Other changes
Additions
Added an option to skip plugin scanning to Preferences -> Effects.
Added an overflow menu, as well as speed and pitch indicators to clips.
Added subtitle formats for labels. Export to WebVTT and SubRip and import of SubRip files is now supported. (Thanks, Pokechu22 and Larry Bordowitz!)
Changes
Reworked the plugin manager.
Improved accessibility. (Thanks, David Bailes!)
When zooming in vertically (Ctrl+scroll on the vertical scale), the zeroline now remains centered. Moving the vertical zoom off-center still is possible via Shift+scroll on the vertical scale.
Changed the look of the selection adjust cursors (previously pointing fingers on Windows and macOS, now look like >| everywhere).
Changed the timeline options button from a green triangle to a settings gear. From it, you can switch between Beats & Measures or hh:mm:ss timeline rulers, set various preferences regarding to looping, as well as playhead behaviors: "Scroll view to playhead" (previously: "Update display while playing") and "Continuous scrolling" (previously: Pinned Play Head).
Improved BSD support. (Thanks, Brad Smith!)
macOS: Changed the Audacity.app icon on macOS to fit new design guidelines.
Reordered some menus.
Moved OK/Cancel buttons of effects to the bottom.
Removals
There have been a number of removals of niche features to simplify the app. This should make the app a bit less overwhelming to use, and also will speed up future development as fewer things need to be considered.
Removed the read-only mouse preferences page.
Removed Printing options.
Removed Screenshot tool. To make a screenshot, use Win+Shift+S (Windows) or Cmd+Shift+4 (Mac) instead.
Removed Karaoke view.
Removed the "solo=none" preference.
Removed timeline tooltips preference.
Removed "dragging selection edges" preference.
Removed some warning dialogs and associated preferences.
Removed "scrolling left of zero" preference.
Replaced "Advanced Vertical Zooming" with new always-on behavior.
Removed some vertical zoom presets.
Removed EQ XML to TXT converter, which was needed for the Audacity 2.3 -> 2.4 transition. It is now a plugin instead, downloadable at https://plugins.audacityteam.org/additional-resources/eq-curves/eq-xml-to-txt-converter.
Removed the "Vocal reduction and isolation" effect. As a replacement on Windows and Linux, the Intel OpenVINO plugins work better and on a wider array of content, including mono tracks. The old effect still can be downloaded from https://plugins.audacityteam.org/nyquist-plugins/effect-plugins/filters-and-eq#vocal-reduction-and-isolation

Switched from mad to mpg123 as MP3 importer
License update
Audacity binaries are now licensed under the GNU General Public License, Version 3.
Most code files remain GPLv2-or-later, but VST3 support required this license update.
More information can be found in the announcement post: #2142
Removals
Removed the Zoom Tool. You can use the zoom buttons or Ctrl+Scroll (macOS: Cmd+Scroll) to zoom instead.
The Audacity Manual HTML pages are no longer included in the installation.
If you require offline access of the manual, you can download it here: https://github.com/audacity/audacity-manual/releases

Audacity 3.0.5 was released
Changes and improvements since previous version
Audacity 3.0.5 replaces all previous macOS versions.
This is a hotfix release that fixes a bug on macOS that could corrupt project files when being opened via cmd+o on languages where the decimal separator wasn't a dot.
Other than that, this release is identical to Version 3.0.3.
Audacity 3.0.4 was released on 24 Aug 2021.
This is a hotfix release that fixes a bug with envelope points, which could multiply uncontrollably and cause Audacity to crash. In particular:
#1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
#1477: Filter Curve EQ will crash if there is an envelope point outside of the selection
This fix re-introduces an earlier, but way less destructive bug:
bugzilla 208 / #1500: Some effects delete Envelope Control Points, or do not move them when timeline changes
Other than that, this release is identical to Version 3.0.3.
3.0.3
Changes since version 3.0.2:
Display of Track Name
A new command has been added to the View menu, View > Track Name (on / off).
When this is enabled the audio track name is displayed superimposed translucently at top left of all audio tracks.
Note that the track name is always shown in the Track Control Panel but will be truncated if the name is too long to fit.
View Menu Show Track Name.png
This has the same effect as the setting for Show track name as overlay in Tracks Preferences.

Changes since version 2.4.2:
Improvements
* Audacity now uses 'aup3' format, with all audio in one file, rather than the previous 'pile of file' format. We are using the SQLite library to manageis the contents of this file. Too many users were previously getting caught out by copying part of the project only, when backing up.

2.2.2
Changes since version 2.2.1:
Improvements
* Dropout detection Dropout detection is controlled from a setting in Recording Preferences called "Detect dropouts". When this setting is "on" (default setting) Audacity will detect dropouts (brief gaps in the recording) and will insert zeroes into the recording to keep the other good parts synchronized. These silent spans will make the dropouts more obvious, but keep the duration of the recording correct. When recording stops, a Warning message box alerts the user and a label track, called "Dropouts", is added showing the lost parts, labeled with consecutive numbers.
* Improved horizontal zooming For this release we have improved the way zooming using your mouse wheel works and provided a new Zoom Toggle function.
* Improved vertical zooming We have added a context menu to the vertical scale to control vertical zooming Previous vertical zooming methods (left-click in the vertical ruler, left-drag in the vertical ruler) remain available by selecting "Advanced Vertical Zooming" in Track Behaviors Preferences.
* "Extra" menu The "Ext-Bar" and "Ext-Command" menus have been consolidated into the "Extra" menu.
* Theme tweaks The appearance and/or contrast of a few icons has been improved.
* Easier access to changing key bindings for shortcuts For menu commands that are enabled (not grayed-out) if you hold the Shift key and click on the sub-menu item, instead of executing the command the Keyboard Preferences pop open at the chosen command. You can then change that (or any other) shortcut binding.
* Language selection in Preferences Interface Preferences has been upgraded so when selecting languages the proper spelling of these languages is shown with accented and special characters.
Bug Fixes
* Multiple use of "Save As" to the existing open project can result in data corruption/loss
* Crash undoing during record, using Discard button of History window
* Exporting audio in compressed formats to device with insufficient space produces inconsistent/truncated results
* In Export Multiple, Cancel does not remove the file that is in progress when Cancel is chosen
* Unicode page encodings fixed ( ° °)
* Crash using SBSMS pitch change at low sample rate
* (Mac) Equalization: "Telephone" curve displays a flat line, no sound on Preview
* Toolbars: open undocked if previously not shown, unless Reset Toolbars first
* Analysis effects that create labels should give focus to label track
* Control value may be out of range when using FloatingPointValidator
* Analysis effects produce false indication that a label is open for editing
* Import Uncompressed File Dialog Incorrect Reference to Menu Item
* Wave Color not grayed out in TCP dropdown menu when in Spectrogram view
* Hover indication on note track channel toggle appears on all tracks (when they rerender)
* Installer has old logo for 2.2.1 and 2.2.0

2.2.1
Changes since version 2.2.0:
Improvements
* Waveform colorways
You can optionally change the colorway of the waveforms displayed in your project.
The setting is per track and not per project so you can have multiple colorways
in the same project.
* "Save Other" reverts to "Export" in the File menu
When we made the menu changes for 2.2.0 we introduced an entry into the File menu
called "Save Other" which led to a sub-menu for exporting various audio formats.
Many users were confused by this change and found it hard to find where they could
export audio from. So for 2.2.1 we have changed that menu entry to be File > Export.
Bug Fixes
* Release 2.2.1 is mainly a maintenance release.
Soon after the release of 2.2.0 we discovered some problematical bugs in Audacity:
Bug #1767 - Opening a second project from Mac's Finder produces a second
inaccessible instance of Audacity
Bug #1770 - Crash applying certain chain files
Bug #1783 - Preview fails when selection extends before zero
Bug #1787 - Auto-scroll stopped working in 2.2.0
Bug #1765 - Using File > Open to import audio gives wrong zoom level
and no scroll bar slider

* Sync-Lock button removed (use menu item or keyboard shortcut instead)
* New preferences and preference pages
* Overhaul of much code:
* Overhaul of envelope handling code to deal with some anomalies
* Overhaul of exception handling for greater safety

Bug Fixes
* Major work on bug fixing. 198 bugs that were in 2.1.3 were fixed for 2.2.0.
* The most serious bug fixed this time round was bug 437 which was about what happens when Audacity is recording and runs out of storage.
* Most of the bugs fixed were more minor, such as bug 463 which was about a case in which the numbering on the timeline could display
incorrect times.

* Device names were corrupted when using system language other than English.
* Fixed crashes using (external program).
* Waves v9 Audio Units should now work correctly.
* GNU/Linux:

* Fix segfault exporting an FFmpeg format to an unwritable folder.
* Fix silent failure exporting FFmpeg, MP2 or OGG to an unwritable folder.
* Fix ENTER activated an effect when OK button was greyed out.
* Addendum:
* The previous Audacity 2.0.6 version fixed an issue that projects did not reopen correctly if they contained tracks having 2^31 samples or greater of audio (just over 13.5 hours at 44100 Hz).
Changes since version 2.0.5
Improvements
Interface:
Redesigned, searchable Keyboard Preferences with Tree, Name and Key views.
Edit Menu: "Cut" and "Delete" are now in the top level of the menu.
Transport Menu now includes "Play/Stop" and "Play/Stop and Set Cursor" (use Keyboard Preferences to create shortcuts for "Play" and "Stop").
Tracks Menu now includes "Mix and Render to New Track".
Track Drop-Down Menu now has Move Track To Top and Move Track To Bottom.
New right-click menu choice "Delete Label" to remove single labels.
"Snap To" now offers choice of snap to the "closest" or "prior" position. Note: the previous "Snap To On" keyboard shortcut will no longer work.
"Snap To" settings are now independent for each project.
Effects:
Truncate Silence: redesigned with simpler option "Truncate Detected Silence" to shorten to the specified length without compressing silence.
VST effects: New "Settings" dialog lets you specify buffer size (for faster processing) and enable buffer delay compensation (to prevent inserted silence). Compensation may cause a crash in a few plug-ins.
VST effects now support standard FXP presets.
LV2 effects are now supported on all platforms (textual interface only).
Import or export using FFmpeg now requires FFmpeg 1.2 or later (or libav 0.8 or later). For recommended downloads of recent FFmpeg please visit http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown.
New Tamil translation (largely complete).
(Windows) FLAC exports can now exceed 2 GB in size.
(OS X) Easier Audacity installation using the DMG: drag the Audacity folder to the /Applications shortcut.
(Linux) Self-compiled builds of Audacity now search for system LADSPA effects in /usr/lib/ladspa.
Bug Fixes
Interface:
Region Restore did not restore the region after using Preferences.
Dragging selections with the keyboard or Selection Toolbar digits was very slow.
(Windows) Help > About Audacity crashed when run in Magyar language.
(OS X) Some full and reduced Menu Bar items were not translated.
(OS X and Linux) Fixed various interface crashes.
Effects:
Reverb and Paulstretch were missing from Chains.
Analyze > Contrast could report very inaccurate rms levels.
Noise Removal: Attack and decay times were half as long as set.
(OS X and Linux) Nyquist effects ran much more slowly than on Windows.
Click or drag on the Timeline after Loop Play continued to loop.
Transcription Toolbar did not play slower than 0.1x speed.
(Linux) Audacity did not build if python 2 was not available.
Changes since version 2.0.4:
Bug fixes for:
* Shaped dither was corrupted and too loud on all stereo exports except FLAC.
* Keyboard Preferences: some Edit and Align commands for different sub-menus showed the same name.
* Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
* In locales that use comma for decimal separator: * Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem. * Built-in generators produced silence after running a Nyquist effect.
* (Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
* (Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
* (OS X) Frequent crashes occurred on importing audio files on some machines.
* (OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon.
* (Linux 64-bit) Fixed a crash when using Equalization.
* (Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB.
* (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared.
Changes and Improvements:
* Tracks Menu:
* The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands.
* "Align and Move Cursor" renamed to "Move Selection when Aligning".
* Label Tracks:
* Labels Editor now allows empty labels to be saved on closing the editor.
* TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label.
* (Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
* (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
* (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units.
* (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
* (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
Changes since version 2.0.3:
Bug fixes for:
* Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
* Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or afterrunning the effect then reopening it.

* Bass Boost no longer clips if the track contains 32-bit audio.
* Auto Duck was excessively slow on older machines.
* (Windows) Exported MP3 comments tags were not seen by Windows programs.
* (Windows and OS X) Audacity crashed if you used system quit before file import was complete.
* (Linux) Equalization crashed Audacity if the XML file was corrupted.
* (Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash.
* (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
* Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
* Numerous other interface fixes.
Changes and Improvements:
* New "Reverb" effect to replace GVerb, based on the original "Freeverb".
* New View > Go to Selection Start and Go to Selection End commands.
* New "Align End to End" command to append existing tracks to each other.
* Change Tempo now supports fractional BPM.
* Plot Spectrum now supports FFT sizes up to 65536.
* WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO tags and also support ID3 tags.
* Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
* (Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
* (Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
* (Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.

* Modules Preferences replaced with a dialog on launch of Audacity enabling you to choose which modules to load.
Changes since version 2.0.2:
Bug fixes for:
* Crash using Undo whilst time-shifting a track.
* Crash using Repair if the selection extended into an empty track.
* Export Multiple didn't prevent export if there was no audio or all audio was muted. This allowed export of small invalid files.
* Time Track:
* Loop Play of a speeded-up track inserted silence.
* Playback and rendering was significantly inaccurate, creating audible and visual glitches.
* Accessibility:
* The mnemonics character "&" was read out by screen readers in most of the Preferences choices.
* NVDA did not read static text in most dialogs. Text can now be read by using INSERT + B.
* JAWS and Window-eyes misread the "Duration" control in Silence Generator.
* Toolbar buttons could not be pressed by ENTER
* Other interface bug fixes.
Changes and Improvements:
* The SoX Resampler library (libsoxr) has replaced libresample in Audacity releases, offering both higher quality and greater speed. .
* Time Tracks new features:
* "Set Range" now changes only the range of the Time Track, preserving the pitch/speed set by any existing warp points.
* Vertical scale added with options for linear and logarithmic display and interpolation.
* Upper and lower speed limits will now be remembered when saving and reopening a project in 2.0.3. Warp points in projects saved by previous Audacity versions will be correctly restored in 2.0.3.
* Warp points saved in a 2.0.3 project will be preserved if opened in previous versions but playback and display will be incorrect.
* New effects:
* Studio Fade Out (uses a filtered "S" curve).
* Adjustable Fade (accessible effect for creating partial fades and adjustable fade shapes).
* Bass and Treble (replaces Bass Boost).
* Real sample rates up to 384000 Hz are now supported for playback and recording in high resolution devices (the maximum is up to 192000 Hz for Windows DirectSound host).
* Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now allows splits to be placed at point labels. Labeled audio regions
that touch without overlapping are treated as separate regions. Overlapping labeled audio regions are treated as a single region.
* Compilation: cmake is required in order to build libsoxr.
* New Croatian translation of Audacity.
Changes since version 2.0.1:
Bug fixes for:
* Interface:
* "Retain labels" Interface Preference did not retain labels for a region that snapped exactly to both label edges.
* Projects did not save the track selected state.
* (OS X, Linux) Timer Record: Interlinking of the Start, End and Duration controls was broken.
* (Windows) JAWS screen-reader did not read the "Draw curves" and "Graphic EQ" radio buttons in Equalization correctly.
* Envelopes and Clips:
* Exporting (or any render operation) on a track containing split lines could create clicks at the split lines.
* Dragging a clip into another track caused a crash if Sync-Lock Tracks was enabled and there was also a label track.
* Effects and Analysis:
* Normalize could crash if the track name contained "%".
Changes and Improvements:
* Duration controls when generating at a point now default to hh:mm:ss + milliseconds format. Selection Toolbar also defaults to that format on first installation or resetting preferences.
* Toolbars visual improvements:
* "Snap To" in Selection Toolbar now has an explanatory tooltip.
* Device Toolbar tooltips now display the selected device.
* Increased default width of Device Toolbar and Meter Toolbar.
* Improvements and some bug fixes to Nyquist effects, including:
* Delay (new option to prevent duration change)
* Sample Data Export (new "L-R on Same Line" layout option)
* Risset Drum (new "Amplitude" slider).
* Importing a labels file writes the file name to the name of the Label Track, and exporting a labels file offers the name of the last Label Track in the project.
* Removed the "Audio cache" option from Directories Preferences due to frequent crash reports. All data operations will now be written to disk and not to RAM.
* Removed the FFmpeg "On-Demand" option from Libraries Preferences (this fixes Audacity not building if configured --without-ffmpeg).
* Compilation: Progress on making the Modules feature mainstream. Modules can now be individually enabled and disabled in Preferences.
Changes since version 2.0.0:
Bug fixes for:
* Interface:
* Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
* Finding zero crossings could cause the selection to expand into white space at either side of the clip.
* Clips did not drag to another track if mouse was over a selection.
* Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
* Imports, Exports and Files:
* Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
* (Mac) Fixed crashes importing MP3 files on PPC machines.
* (Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).
* Effects and Analysis:
* Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
* Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
* Other miscellaneous bug fixes, including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen,
Changes and Improvements:
* Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
* Nyquist Effect plug-ins can now be added to Chains.
* New "Paulstretch" effect for extreme slowdown without pitch change.
* New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.
* New Preference (off by default) to import files On-Demand (without seek ability) when using the optional FFmpeg library.
* New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.
* (Windows installer) New option to reset Preferences on next launch.
* (Mac) Audacity now has excellent compatibility with the VoiceOver screen reader. For details, please see: http://manual.audacityteam.org/help/manual/man/accessibility.html#mac .

Changes since version 1.3.14 Beta
Bug fixes for:
* Interface:
* Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
* (Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.
* Imports and Exports:
* Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
* Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
* Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
* (Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.
* Effects and Analysis:
* Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
* Fixed Plot Spectrum background could be transparent on some machines.
* Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
* Chirp, Tone and Silence generators now remember their settings.

Changes in version 1.3.14 Beta:
Bug fixes for:
* Interface:
* Excessive delay occurred when typing into labels in long projects.
* Last digit of TimeText controls could not be manipulated in some formats.
* (Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar.
* (OS X, Linux) Crash occurred if Toolbars were reset during playback or recording.
* Imports and Exports:
* MP2 files were not importable without FFmpeg library or an import rule.
* Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
* Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.
* Effects and Analysis:
* An empty command could be added to a Chain which then displayed a Nyquist error message when run.
* Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.
* Other bug fixes:
* Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence.
* Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
* Fixed some crashes and incorrect movement of audio when dragging tracks.
* (Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
* (Linux) Restore building if USE_PORTMIXER is not defined.
Changes and Improvements:
* Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently.
* Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
* Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
* Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
* CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).
* (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
* (Linux) Set the per-user files directory per the program name set in configure.
* (Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots.
Changes in version 1.3.13 Beta:
Bug fixes for:
* Interface:
* Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
* Generating inside a clip could modify the clip length or create spurious clips.
* Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name.
* Edit > Region Save did not save the cursor position.
* (Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks.
* (Windows) Some Unicode characters could not be typed into labels, or caused a freeze using some input methods.
* (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
* Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.
* Imports and Exports:
* Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
* Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
* New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
* Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
* U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
* Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled.
* (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).
* Other bug fixes:
* Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
* (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
* (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.
* (Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough.
* (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate.
Changes and Improvements:
* Control Toolbar renamed to Transport Toolbar.
* Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
* New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
* Equalization: New "Manage Curves" dialog for importing and exporting curves.
* Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise.
* New "Extended Import" Preferences for specifying different importers to open specific file extensions.
* Improved Automatic Crash Recovery with all project changes autosaved.
* MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
* (Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project.
* (OS X) Simpler installer with top-level "Auadacity" folder.

The new features in Audacity 1.3 have been grouped into the following six major categories. Click on the links below for more information.
1. Collapse/Expand Tracks
2. Multiple clips per track
3. Selection Bar
4. Improved Label Tracks
5. QuickTime and Audio Units on Mac OS X
6. Other features
Changes in Audacity 1.2.4
* The File menu now includes a list of recent files.
* The "Generate Silence" effect now prompts for a length.
* Audacity is now built with Vorbis 1.1, which features better encoding quality and file compression.

* Better support for certain audio devices on Mac OS X 10.4 "Tiger"
* The "View History" window can now discard old undo levels to save disk space on Windows. (This previously worked only on Linux and Mac.)
* "Preferences" command is now in Edit menu.
* "Plot Spectrum" command is now in Analyze menu.
* Opening a project file saved by a later version of Audacity displays an intelligent error message. Also, trying to import a project file (instead of open it) displays an intelligent error message.
* Audacity now compiles in Visual C++ .NET 2003.
* Other minor bug fixes.
* New or updated translations: Arabic (ar), Czech (cs), Finnish (fi), Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl), Simplified Chinese (zh_CN), Traditional Chinese (zh_TW).
Changes in Audacity 1.2.3
* Windows: Fixed a bug that caused recording to stop or display incorrectly after about 50 minutes, on some Windows systems. (This was partly fixed in Audacity 1.2.2, but still didn't work on some systems.)
* Mac OS X: Fixed a major bug that caused Audacity to crash at seemingly-random times on Mac systems, especially during playback or recording.
* The Change Pitch and Change Tempo effects have been upgraded to use a new version of the SoundTouch library by Olli Parviainen, with better speed and higher quality.
* libsndfile has been upgraded to version 1.0.11. Audacity can now import Sound Designer II (SDII) files.
* Fixed a bug that caused the program to run slowly when using the Envelope tool.
* Shift-clicking on a mute or solo button now un-mutes (or un-solos) all other tracks.
* Nyquist plug-ins can now accept strings as input. Also, a "Debug" button has been added to Nyquist effect dialogs, which allows you to see all of the output produced by Nyquist, for aid in debugging.
* When the audio file referenced ("aliased") by an Audacity project is missing, Audacity will now always play silence. Before, Audacity would sometimes repeat the most recent audio that was played previously.
* VU Meters will now always reset when audio I/O has stopped.
* New or updated translations: Italian (it), Hungarian (hu), Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh), Norsk-Bokmal (nb), French (fr), Russian (ru).
Changes in Audacity 1.2.2
Meter Toolbar added for monitoring volume levels during playback and recording. Click on the recording meter to monitor the input without recording.
Export Multiple - new feature that lets you export multiple files at once, either by track, or split based on labels.
Attempt to automatically correct latency in full-duplex recordings. (This does not work perfectly, and is not yet supported on all systems. It will improve in future versions.)
Fixed a serious bug that could cause data loss when you save and then reload and re-edit an Audacity project containing repeated or duplicate data.
MP3 tags dialog will only pop up the first time you export as MP3; after that it will not pop up again as long as you have filled in at least one tag.
You can now add a label at the current playback position - in the Project menu, with a shortcut of Ctrl+M.
Clicking on a label now selects all of the tracks, making it easier to use the label track to recall selections.
Windows: Fixed a crash in the Time Track "Set Rate" command.
Fixed a bug that caused problems with recordings over 45 minutes on some Windows systems.
Mac OS X: Improved support for the Griffin iMic by fixing a bug that was causing it to always record in mono instead of stereo.
Added support for Software Playthrough (listen to what you're recording while recording it, or while monitoring using a VU meter) - this makes it possible, for example, to record using one audio device while listening to it play through a separate device.
Unix/Linux: Fixed freeze caused by captured mouse when audio device hangs. (Audacity may not respond, but it will no longer freeze all of X.)
Fixed a cosmetic bug that caused improper waveform display if you tried to open an Audacity project saved on a different platform (e.g., copying a project from a Mac to a PC).
Fixed bug that could cause instability when pasting, splitting, or duplicating a label track.
You can now change the font of a label track by choosing "Font..." from the label track's pop-up menu.
Basic printing support has been added. Currently it scales the entire project to fit exactly on one page. Try printing in landscape orientation for best results.
Mac OS X and Windows: Audacity ships with a newer version (1.0.1) of the Ogg Vorbis encoder. Vorbis compression will now have higher quality and smaller file sizes.
Fix a bug that occasionally caused crashes when applying effects to split tracks.
Zoom In / Zoom Out now properly disable when they're not available.
Always delete temporary files created by the "Preview" feature.
Other minor bug fixes and performance improvements.
Changes in 1.2.1:
* The following translations have been added or updated: Finnish, French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.

* Fix a crash when the temporary directory is not available on startup.
* Correctly load ID3 tags saved in Audacity project files.
* On Linux and OS X, store lockfiles in the temp directory instead of the user's home directory. This fixes problems in lab environments where users have restricted or network-mounted home directories.
* Fix a bug that prevented Nyquist effects from running when certain regional settings were activated.
* Fix a bug in the Quick Mix command that could cause old temporary files to not be deleted.
* Linux: Fix endianness problems in playback on PowerPC.
* Linux: Fix compilation problem in Nyquist on MIPS.
* Linux: Include a more recent PortAudio v19 snapshot (fixes compilation problems when building with the --with-portaudio=v19 option).
* Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."
* Other minor bug-fixes.
Changes since 1.2.0-pre4:
* New cross-fade effects.
* Fix problem where samples were drawn in the wrong position when zoomed all the way in. This caused the drawing tool to move a different sample than the one under the cursor.
* Don't use id3v2.4 tags, which are not yet supported by most players. (This was fixed in 1.2.0-pre2, but appeared again by accident in 1.2.0-pre3.)
* Correctly display translated messages in the status bar.
* When the cursor is on-screen, the Zoom In button now zooms to the area around the cursor.

debugging. Eventually it will probably move to XML.
* Improved handling of wave tracks: as before, the data
is stored in blocks, but now, the blocks are correctly
limited to betweek n and 2n bytes each (for some n),
which guarantees editing operations always take the
same amount of time, while also ensuring that projects
don't get more fragmented over time.
* Rewritten user interface code. The shades of gray
are taken from the OS, and the project window has been
redesigned to have more consistent layout across all
platforms.
* Selecting "Open" now does the smart thing, opening a
project if you give it a project, or importing a WAV
file if you give it that.

Audacity 3.6.0
Major changes
Master effects
Audacity now features master effects. Master effects are effects which apply to the entire project at once. More information can be found at Using master effects & realtime effects.
New compressor and limiter
A new compressor and limiter has been added, replacing the previous versions. A gain reduction history has been added to these effects when they're used as a realtime effect.
Factory Presets suitable for a wide range of use cases for these effects have been provided by Vladislav Isaev and Marek Iwaszkiewicz, available via the Presets & Settings button.
New themes
Audacity now features new and improved dark and light themes. You can switch between themes via Preferences -> Interface. The theme previously used still is around as the Classic theme, and themes even older than that can be optionally installed as custom themes from here.
Updated instructions on creating custom themes can be found here.
Increased performance
Audacity is now quite a bit snappier than before, especially when working on larger projects and on larger screens.
Other changes
Added FFmpeg 7 support.
You now can paste audio files into Audacity using Ctrl+V.
Alternative waveform colors are now themeable by custom themes.
Removed the track name overlay preference and the "blend themes" preference.
Scripting: Added GetInfo: Type=Selection. (Thanks, Jonatã Bolzan Loss!)
Added an Extras > Export > Export Selected Audio option.
Import Raw: Added support for offsets larger than 2 GB.
Redesigned the "what's new" dialog.
Added an option to the View menu to show/hide RMS in waveforms.
OpenVINO AI effects can now be downloaded from audacityteam.org/download/openvino/
Bugfixes
#6340 When recording to a new track, the track is now scrolled back into view again.

Various compiler warning fixes and OpenBSD build fixes. (Thanks, Brad Smith!)
Audacity 3.5.1
This is a hotfix release. It fixes the following bugs:
#6322 Fixed a crash on launch on macOS 11 and older.
#6324 Fixed the update notification looking for alpha versions instead of release versions.
#6321 Fixed a freeze when using macros on multiple files.
Audacity 3.5.0
Audacity 3.5 adds cloud saving, beat detection, pitch shifting and more.
Major changes
Cloud project saving
We've introduced a new cloud-saving feature that allows you to save your Audacity projects to audio.com. This allows you to work from any device, share & collaborate with others and restore previous versions if something went wrong.
Automatic tempo detection
Audacity can now automatically detect the tempo of imported loops, and adjust them to be in tempo.
Tempo detection is done via both audio analysis and metadata checking. If you want to prepare your loop for automatic tempo detection without relying on audio analysis, both acidizer tempo tags or simply writing "123 bpm" anywhere into the filename work.
Automatic tempo detection can be turned off via Preferences -> Import/Export.
Pitch shifting
You now can non-destructively change the pitch of a clip by holding Alt and pressing the Up and Down arrow keys. Alternatively, you can click on the overflow menu (...) and select "Pitch and speed...". When changing the pitch this way, an arrow in the UI indicates how much you've shifted it.
Other changes
Additions
Added an option to skip plugin scanning to Preferences -> Effects.
Added an overflow menu, as well as speed and pitch indicators to clips.
Added subtitle formats for labels. Export to WebVTT and SubRip and import of SubRip files is now supported. (Thanks, Pokechu22 and Larry Bordowitz!)
Changes
Reworked the plugin manager.
Improved accessibility. (Thanks, David Bailes!)
When zooming in vertically (Ctrl+scroll on the vertical scale), the zeroline now remains centered. Moving the vertical zoom off-center still is possible via Shift+scroll on the vertical scale.
Changed the look of the selection adjust cursors (previously pointing fingers on Windows and macOS, now look like >| everywhere).
Changed the timeline options button from a green triangle to a settings gear. From it, you can switch between Beats & Measures or hh:mm:ss timeline rulers, set various preferences regarding to looping, as well as playhead behaviors: "Scroll view to playhead" (previously: "Update display while playing") and "Continuous scrolling" (previously: Pinned Play Head).
Improved BSD support. (Thanks, Brad Smith!)
macOS: Changed the Audacity.app icon on macOS to fit new design guidelines.
Reordered some menus.
Moved OK/Cancel buttons of effects to the bottom.
Removals
There have been a number of removals of niche features to simplify the app. This should make the app a bit less overwhelming to use, and also will speed up future development as fewer things need to be considered.
Removed the read-only mouse preferences page.
Removed Printing options.
Removed Screenshot tool. To make a screenshot, use Win+Shift+S (Windows) or Cmd+Shift+4 (Mac) instead.
Removed Karaoke view.
Removed the "solo=none" preference.
Removed timeline tooltips preference.
Removed "dragging selection edges" preference.
Removed some warning dialogs and associated preferences.
Removed "scrolling left of zero" preference.
Replaced "Advanced Vertical Zooming" with new always-on behavior.
Removed some vertical zoom presets.
Removed EQ XML to TXT converter, which was needed for the Audacity 2.3 -> 2.4 transition. It is now a plugin instead, downloadable at https://plugins.audacityteam.org/additional-resources/eq-curves/eq-xml-to-txt-converter.
Removed the "Vocal reduction and isolation" effect. As a replacement on Windows and Linux, the Intel OpenVINO plugins work better and on a wider array of content, including mono tracks. The old effect still can be downloaded from https://plugins.audacityteam.org/nyquist-plugins/effect-plugins/filters-and-eq#vocal-reduction-and-isolation
Bugfixes
Fixed a number of dialogs that were able to grow too large to fit on the screen.
#2133 Fixed the playback cursor sometimes desynchronizing with actual playback. (Thanks, David Bailes!)

Plugins now automatically get scanned, tested and enabled when Audacity starts.
System changes
Apple Silicon (arm64) is now supported on macOS
Note: When using an arm64 Audacity, you must use arm64 versions of FFMPEG and plugins. Plugins for x86-64 (Intel macs) will not load.
For the time being, Audacity will continue to download x86-64 versions by default to avoid these incompatibilities,
but you can download an arm64 version from Github releases: https://github.com/audacity/audacity/releases
FFMPEG 5.0 (avformat 59) is now supported, in addition to avformat 55, 57 and 58
Added support for Wavpack
On Linux, Audacity can now be compiled without JACK present.

Note: If you are upgrading from a previous version, Audacity will keep using the ~/.audacity-data and ~/.audacity folders until you delete them.
Switched from mad to mpg123 as MP3 importer
License update
Audacity binaries are now licensed under the GNU General Public License, Version 3.
Most code files remain GPLv2-or-later, but VST3 support required this license update.
More information can be found in the announcement post: #2142
Removals
Removed the Zoom Tool. You can use the zoom buttons or Ctrl+Scroll (macOS: Cmd+Scroll) to zoom instead.
The Audacity Manual HTML pages are no longer included in the installation.
If you require offline access of the manual, you can download it here: https://github.com/audacity/audacity-manual/releases

Audacity 3.0.5 was released
Changes and improvements since previous version
Audacity 3.0.5 replaces all previous macOS versions.
This is a hotfix release that fixes a bug on macOS that could corrupt project files when being opened via cmd+o on languages where the decimal separator wasn't a dot.
Other than that, this release is identical to Version 3.0.3.
Audacity 3.0.4 was released on 24 Aug 2021.
This is a hotfix release that fixes a bug with envelope points, which could multiply uncontrollably and cause Audacity to crash. In particular:
#1476: Envelope points are multiplied when using Filter Curve EQ or Graphic EQ
#1477: Filter Curve EQ will crash if there is an envelope point outside of the selection
This fix re-introduces an earlier, but way less destructive bug:
bugzilla 208 / #1500: Some effects delete Envelope Control Points, or do not move them when timeline changes
Other than that, this release is identical to Version 3.0.3.
3.0.3
Changes since version 3.0.2:
Display of Track Name
A new command has been added to the View menu, View > Track Name (on / off).
When this is enabled the audio track name is displayed superimposed translucently at top left of all audio tracks.
Note that the track name is always shown in the Track Control Panel but will be truncated if the name is too long to fit.
View Menu Show Track Name.png
This has the same effect as the setting for Show track name as overlay in Tracks Preferences.

2.2.2
Changes since version 2.2.1:
Improvements
* Dropout detection Dropout detection is controlled from a setting in Recording Preferences called "Detect dropouts". When this setting is "on" (default setting) Audacity will detect dropouts (brief gaps in the recording) and will insert zeroes into the recording to keep the other good parts synchronized. These silent spans will make the dropouts more obvious, but keep the duration of the recording correct. When recording stops, a Warning message box alerts the user and a label track, called "Dropouts", is added showing the lost parts, labeled with consecutive numbers.
* Improved horizontal zooming For this release we have improved the way zooming using your mouse wheel works and provided a new Zoom Toggle function.
* Improved vertical zooming We have added a context menu to the vertical scale to control vertical zooming Previous vertical zooming methods (left-click in the vertical ruler, left-drag in the vertical ruler) remain available by selecting "Advanced Vertical Zooming" in Track Behaviors Preferences.
* "Extra" menu The "Ext-Bar" and "Ext-Command" menus have been consolidated into the "Extra" menu.
* Theme tweaks The appearance and/or contrast of a few icons has been improved.
* Easier access to changing key bindings for shortcuts For menu commands that are enabled (not grayed-out) if you hold the Shift key and click on the sub-menu item, instead of executing the command the Keyboard Preferences pop open at the chosen command. You can then change that (or any other) shortcut binding.
* Language selection in Preferences Interface Preferences has been upgraded so when selecting languages the proper spelling of these languages is shown with accented and special characters.
Bug Fixes
* Multiple use of "Save As" to the existing open project can result in data corruption/loss
* Crash undoing during record, using Discard button of History window
* Exporting audio in compressed formats to device with insufficient space produces inconsistent/truncated results
* In Export Multiple, Cancel does not remove the file that is in progress when Cancel is chosen
* Unicode page encodings fixed ( ° °)
* Crash using SBSMS pitch change at low sample rate
* (Mac) Equalization: "Telephone" curve displays a flat line, no sound on Preview
* Toolbars: open undocked if previously not shown, unless Reset Toolbars first
* Analysis effects that create labels should give focus to label track
* Control value may be out of range when using FloatingPointValidator
* Analysis effects produce false indication that a label is open for editing
* Import Uncompressed File Dialog Incorrect Reference to Menu Item
* Wave Color not grayed out in TCP dropdown menu when in Spectrogram view
* Hover indication on note track channel toggle appears on all tracks (when they rerender)
* Installer has old logo for 2.2.1 and 2.2.0

2.2.1
Changes since version 2.2.0:
Improvements
* Waveform colorways
You can optionally change the colorway of the waveforms displayed in your project.
The setting is per track and not per project so you can have multiple colorways
in the same project.
* "Save Other" reverts to "Export" in the File menu
When we made the menu changes for 2.2.0 we introduced an entry into the File menu
called "Save Other" which led to a sub-menu for exporting various audio formats.
Many users were confused by this change and found it hard to find where they could
export audio from. So for 2.2.1 we have changed that menu entry to be File > Export.
Bug Fixes
* Release 2.2.1 is mainly a maintenance release.
Soon after the release of 2.2.0 we discovered some problematical bugs in Audacity:
Bug #1767 - Opening a second project from Mac's Finder produces a second
inaccessible instance of Audacity
Bug #1770 - Crash applying certain chain files
Bug #1783 - Preview fails when selection extends before zero
Bug #1787 - Auto-scroll stopped working in 2.2.0
Bug #1765 - Using File > Open to import audio gives wrong zoom level
and no scroll bar slider

* Sync-Lock button removed (use menu item or keyboard shortcut instead)
* New preferences and preference pages
* Overhaul of much code:
* Overhaul of envelope handling code to deal with some anomalies
* Overhaul of exception handling for greater safety

Bug Fixes
* Major work on bug fixing. 198 bugs that were in 2.1.3 were fixed for 2.2.0.
* The most serious bug fixed this time round was bug 437 which was about what happens when Audacity is recording and runs out of storage.
* Most of the bugs fixed were more minor, such as bug 463 which was about a case in which the numbering on the timeline could display
incorrect times.

* Items in the Effect, Generate or Analyze Menus can be sorted or grouped by name, publisher or class of effect.
* Noise Removal is improved and renamed to "Noise Reduction".
* Change Speed has new time controls for current and new length. You can now enter the speed change as a multiplier e.g. "2" is twice as fast.
* New "Crossfade Tracks" effect can be used for crossfading two tracks. This replaces Cross Fade In and Cross Fade Out.
* Nyquist Prompt and most shipped Nyquist effects now have Preview button.
* Interface:
* Redesigned Meter Toolbars: The default shows separate Record and Playback Meters, half-height so they can be wider while docked, in gradient style.

* Transcription Toolbar (Play-at-speed) can now loop play and cut-preview.
* Timer Record now saves recordings automatically into an existing project.
* New Armenian translation.
* Operating system and sound device support:
* (Windows) Audacity 2.1.0 requires Windows XP SP3 (32-bit) or XP SP2 (64-bit), Vista, Windows 7, Windows 8 or 8.1.

* Please report any issues with WASAPI recording/playback or Yosemite to http://audacity.sourceforge.net/contact/#feedback .
* (Linux Ubuntu) Under Unity, keyboard shortcuts are not visible in the Audacity menus. Keyboard shortcuts are visible if you install the classic GNOME Flashback interface or under Unity if you open Audacity with the UBUNTU_MENUPROXY=0 environment variable. Audacity compiled from source will ship with src/audacity.desktop.in set to UBUNTU_MENUPROXY=0 but it will remain up to distributions to use this desktop file.
Bug fixes:

* Device names were corrupted when using system language other than English.
* Fixed crashes using (external program).
* Waves v9 Audio Units should now work correctly.
* GNU/Linux:

* Fix segfault exporting an FFmpeg format to an unwritable folder.
* Fix silent failure exporting FFmpeg, MP2 or OGG to an unwritable folder.
* Fix ENTER activated an effect when OK button was greyed out.
* Addendum:
* The previous Audacity 2.0.6 version fixed an issue that projects did not reopen correctly if they contained tracks having 2^31 samples or greater of audio (just over 13.5 hours at 44100 Hz).
Changes since version 2.0.5
Improvements
Interface:
Redesigned, searchable Keyboard Preferences with Tree, Name and Key views.
Edit Menu: "Cut" and "Delete" are now in the top level of the menu.
Transport Menu now includes "Play/Stop" and "Play/Stop and Set Cursor" (use Keyboard Preferences to create shortcuts for "Play" and "Stop").
Tracks Menu now includes "Mix and Render to New Track".
Track Drop-Down Menu now has Move Track To Top and Move Track To Bottom.
New right-click menu choice "Delete Label" to remove single labels.
"Snap To" now offers choice of snap to the "closest" or "prior" position. Note: the previous "Snap To On" keyboard shortcut will no longer work.
"Snap To" settings are now independent for each project.
Effects:
Truncate Silence: redesigned with simpler option "Truncate Detected Silence" to shorten to the specified length without compressing silence.
VST effects: New "Settings" dialog lets you specify buffer size (for faster processing) and enable buffer delay compensation (to prevent inserted silence). Compensation may cause a crash in a few plug-ins.
VST effects now support standard FXP presets.
LV2 effects are now supported on all platforms (textual interface only).
Import or export using FFmpeg now requires FFmpeg 1.2 or later (or libav 0.8 or later). For recommended downloads of recent FFmpeg please visit http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown.
New Tamil translation (largely complete).
(Windows) FLAC exports can now exceed 2 GB in size.
(OS X) Easier Audacity installation using the DMG: drag the Audacity folder to the /Applications shortcut.
(Linux) Self-compiled builds of Audacity now search for system LADSPA effects in /usr/lib/ladspa.
Bug Fixes
Interface:
Region Restore did not restore the region after using Preferences.
Dragging selections with the keyboard or Selection Toolbar digits was very slow.
(Windows) Help > About Audacity crashed when run in Magyar language.
(OS X) Some full and reduced Menu Bar items were not translated.
(OS X and Linux) Fixed various interface crashes.
Effects:
Reverb and Paulstretch were missing from Chains.
Analyze > Contrast could report very inaccurate rms levels.
Noise Removal: Attack and decay times were half as long as set.
(OS X and Linux) Nyquist effects ran much more slowly than on Windows.
Click or drag on the Timeline after Loop Play continued to loop.
Transcription Toolbar did not play slower than 0.1x speed.
(Linux) Audacity did not build if python 2 was not available.
Changes since version 2.0.4:
Bug fixes for:
* Shaped dither was corrupted and too loud on all stereo exports except FLAC.
* Keyboard Preferences: some Edit and Align commands for different sub-menus showed the same name.
* Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
* In locales that use comma for decimal separator: * Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem. * Built-in generators produced silence after running a Nyquist effect.
* (Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
* (Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
* (OS X) Frequent crashes occurred on importing audio files on some machines.
* (OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon.
* (Linux 64-bit) Fixed a crash when using Equalization.
* (Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB.
* (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared.
Changes and Improvements:
* Tracks Menu:
* The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands.
* "Align and Move Cursor" renamed to "Move Selection when Aligning".
* Label Tracks:
* Labels Editor now allows empty labels to be saved on closing the editor.
* TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label.
* (Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
* (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
* (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units.
* (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
* (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
Changes since version 2.0.3:

* (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
* Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
* Numerous other interface fixes.
Changes and Improvements:
* New "Reverb" effect to replace GVerb, based on the original "Freeverb".
* New View > Go to Selection Start and Go to Selection End commands.
* New "Align End to End" command to append existing tracks to each other.
* Change Tempo now supports fractional BPM.
* Plot Spectrum now supports FFT sizes up to 65536.
* WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO tags and also support ID3 tags.
* Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
* (Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.

* Export Multiple didn't prevent export if there was no audio or all audio was muted. This allowed export of small invalid files.
* Time Track:
* Loop Play of a speeded-up track inserted silence.
* Playback and rendering was significantly inaccurate, creating audible and visual glitches.
* Accessibility:
* The mnemonics character "&" was read out by screen readers in most of the Preferences choices.
* NVDA did not read static text in most dialogs. Text can now be read by using INSERT + B.
* JAWS and Window-eyes misread the "Duration" control in Silence Generator.
* Toolbar buttons could not be pressed by ENTER
* Other interface bug fixes.
Changes and Improvements:
* The SoX Resampler library (libsoxr) has replaced libresample in Audacity releases, offering both higher quality and greater speed. .
* Time Tracks new features:
* "Set Range" now changes only the range of the Time Track, preserving the pitch/speed set by any existing warp points.
* Vertical scale added with options for linear and logarithmic display and interpolation.
* Upper and lower speed limits will now be remembered when saving and reopening a project in 2.0.3. Warp points in projects saved by previous Audacity versions will be correctly restored in 2.0.3.
* Warp points saved in a 2.0.3 project will be preserved if opened in previous versions but playback and display will be incorrect.
* New effects:
* Studio Fade Out (uses a filtered "S" curve).
* Adjustable Fade (accessible effect for creating partial fades and adjustable fade shapes).
* Bass and Treble (replaces Bass Boost).
* Real sample rates up to 384000 Hz are now supported for playback and recording in high resolution devices (the maximum is up to 192000 Hz for Windows DirectSound host).
* Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now allows splits to be placed at point labels. Labeled audio regions
that touch without overlapping are treated as separate regions. Overlapping labeled audio regions are treated as a single region.
* Compilation: cmake is required in order to build libsoxr.
* New Croatian translation of Audacity.
Changes since version 2.0.1:
Bug fixes for:
* Interface:
* "Retain labels" Interface Preference did not retain labels for a region that snapped exactly to both label edges.
* Projects did not save the track selected state.
* (OS X, Linux) Timer Record: Interlinking of the Start, End and Duration controls was broken.
* (Windows) JAWS screen-reader did not read the "Draw curves" and "Graphic EQ" radio buttons in Equalization correctly.
* Envelopes and Clips:
* Exporting (or any render operation) on a track containing split lines could create clicks at the split lines.
* Dragging a clip into another track caused a crash if Sync-Lock Tracks was enabled and there was also a label track.
* Effects and Analysis:
* Normalize could crash if the track name contained "%".
Changes and Improvements:
* Duration controls when generating at a point now default to hh:mm:ss + milliseconds format. Selection Toolbar also defaults to that format on first installation or resetting preferences.
* Toolbars visual improvements:
* "Snap To" in Selection Toolbar now has an explanatory tooltip.
* Device Toolbar tooltips now display the selected device.
* Increased default width of Device Toolbar and Meter Toolbar.
* Improvements and some bug fixes to Nyquist effects, including:
* Delay (new option to prevent duration change)
* Sample Data Export (new "L-R on Same Line" layout option)
* Risset Drum (new "Amplitude" slider).
* Importing a labels file writes the file name to the name of the Label Track, and exporting a labels file offers the name of the last Label Track in the project.
* Removed the "Audio cache" option from Directories Preferences due to frequent crash reports. All data operations will now be written to disk and not to RAM.
* Removed the FFmpeg "On-Demand" option from Libraries Preferences (this fixes Audacity not building if configured --without-ffmpeg).
* Compilation: Progress on making the Modules feature mainstream. Modules can now be individually enabled and disabled in Preferences.
Changes since version 2.0.0:
Bug fixes for:
* Interface:
* Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
* Finding zero crossings could cause the selection to expand into white space at either side of the clip.
* Clips did not drag to another track if mouse was over a selection.
* Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
* Imports, Exports and Files:
* Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
* (Mac) Fixed crashes importing MP3 files on PPC machines.
* (Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).
* Effects and Analysis:
* Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
* Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
* Other miscellaneous bug fixes, including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen,
Changes and Improvements:
* Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
* Nyquist Effect plug-ins can now be added to Chains.
* New "Paulstretch" effect for extreme slowdown without pitch change.
* New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.
* New Preference (off by default) to import files On-Demand (without seek ability) when using the optional FFmpeg library.
* New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.
* (Windows installer) New option to reset Preferences on next launch.
* (Mac) Audacity now has excellent compatibility with the VoiceOver screen reader. For details, please see: http://manual.audacityteam.org/help/manual/man/accessibility.html#mac .
* CleanSpeech Mode (no longer supported) will not now be enabled even if it was enabled by an earlier version of Audacity.
* Added Serbian (Latin and Cyrillic) translations.
Changes since version 1.3.14 Beta
Bug fixes for:
* Interface:
* Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
* (Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.
* Imports and Exports:
* Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
* Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
* Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
* (Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.
* Effects and Analysis:
* Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
* Fixed Plot Spectrum background could be transparent on some machines.
* Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
* Chirp, Tone and Silence generators now remember their settings.
* Other miscellaneous bug fixes.
Changes and Improvements:
* New Interface preference to show the track name in the display (this
is off by default).
* Longer default Playback preference for effects preview and preview
before cut.
* Restored use of Page Up and Page Down to scroll horizontally.
2.2 Summary of bug fixes and new features between 1.2.6 and 2.0.0
* Bug Fixes:
* Labels now accept lower case "z".
* (Windows Vista/7) Pressing Stop after recording could cause a crash.
* (Mac OS X) Fixed shortcut keys activating when typing in file open or save windows.
* (Mac OS X) Audacity 2.0.0 fully supports Unicode, which fixes an issue where Audacity could not work with folders having non-English characters in their name.

Please visit http://audacity.sourceforge.net/about/features for a full list of features in 2.0.0. You can click Help > Manual (in web browser) in the program to read more.
Changes in version 1.3.14 Beta:
Bug fixes for:
* Interface:
* Excessive delay occurred when typing into labels in long projects.
* Last digit of TimeText controls could not be manipulated in some formats.
* (Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar.
* (OS X, Linux) Crash occurred if Toolbars were reset during playback or recording.
* Imports and Exports:
* MP2 files were not importable without FFmpeg library or an import rule.
* Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
* Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.
* Effects and Analysis:
* An empty command could be added to a Chain which then displayed a Nyquist error message when run.
* Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.
* Other bug fixes:
* Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence.
* Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
* Fixed some crashes and incorrect movement of audio when dragging tracks.
* (Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
* (Linux) Restore building if USE_PORTMIXER is not defined.
Changes and Improvements:
* Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently.
* Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
* Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
* Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
* CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).
* (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
* (Linux) Set the per-user files directory per the program name set in configure.
* (Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots.
Changes in version 1.3.13 Beta:
Bug fixes for:
* Interface:
* Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
* Generating inside a clip could modify the clip length or create spurious clips.
* Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name.
* Edit > Region Save did not save the cursor position.
* (Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks.
* (Windows) Some Unicode characters could not be typed into labels, or caused a freeze using some input methods.
* (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
* Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.
* Imports and Exports:
* Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
* Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
* New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
* Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
* U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
* Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled.
* (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).
* Other bug fixes:
* Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
* (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
* (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.
* (Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough.
* (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate.
Changes and Improvements:
* Control Toolbar renamed to Transport Toolbar.
* Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
* New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
* Equalization: New "Manage Curves" dialog for importing and exporting curves.
* Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise.
* New "Extended Import" Preferences for specifying different importers to open specific file extensions.
* Improved Automatic Crash Recovery with all project changes autosaved.
* MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
* (Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project.
* (OS X) Simpler installer with top-level "Auadacity" folder.

1. Collapse/Expand Tracks
2. Multiple clips per track
3. Selection Bar
4. Improved Label Tracks
5. QuickTime and Audio Units on Mac OS X
6. Other features
Changes in Audacity 1.2.4
* The File menu now includes a list of recent files.
* The "Generate Silence" effect now prompts for a length.
* Audacity is now built with Vorbis 1.1, which features better encoding quality and file compression.
* Dragging sound files into the Audacity window now works on Mac OS X and Linux, as well as Windows. (Before, it worked only on Windows.)
* Better support for certain audio devices on Mac OS X 10.4 "Tiger"
* The "View History" window can now discard old undo levels to save disk space on Windows. (This previously worked only on Linux and Mac.)
* "Preferences" command is now in Edit menu.
* "Plot Spectrum" command is now in Analyze menu.
* Opening a project file saved by a later version of Audacity displays an intelligent error message. Also, trying to import a project file (instead of open it) displays an intelligent error message.
* Audacity now compiles in Visual C++ .NET 2003.
* Other minor bug fixes.
* New or updated translations: Arabic (ar), Czech (cs), Finnish (fi), Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl), Simplified Chinese (zh_CN), Traditional Chinese (zh_TW).
Changes in Audacity 1.2.3
* Windows: Fixed a bug that caused recording to stop or display incorrectly after about 50 minutes, on some Windows systems. (This was partly fixed in Audacity 1.2.2, but still didn't work on some systems.)
* Mac OS X: Fixed a major bug that caused Audacity to crash at seemingly-random times on Mac systems, especially during playback or recording.
* The Change Pitch and Change Tempo effects have been upgraded to use a new version of the SoundTouch library by Olli Parviainen, with better speed and higher quality.
* libsndfile has been upgraded to version 1.0.11. Audacity can now import Sound Designer II (SDII) files.
* Fixed a bug that caused the program to run slowly when using the Envelope tool.
* Shift-clicking on a mute or solo button now un-mutes (or un-solos) all other tracks.
* Nyquist plug-ins can now accept strings as input. Also, a "Debug" button has been added to Nyquist effect dialogs, which allows you to see all of the output produced by Nyquist, for aid in debugging.
* When the audio file referenced ("aliased") by an Audacity project is missing, Audacity will now always play silence. Before, Audacity would sometimes repeat the most recent audio that was played previously.
* VU Meters will now always reset when audio I/O has stopped.
* New or updated translations: Italian (it), Hungarian (hu), Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh), Norsk-Bokmal (nb), French (fr), Russian (ru).
Changes in Audacity 1.2.2
Meter Toolbar added for monitoring volume levels during playback and recording. Click on the recording meter to monitor the input without recording.
Export Multiple - new feature that lets you export multiple files at once, either by track, or split based on labels.
Attempt to automatically correct latency in full-duplex recordings. (This does not work perfectly, and is not yet supported on all systems. It will improve in future versions.)
Fixed a serious bug that could cause data loss when you save and then reload and re-edit an Audacity project containing repeated or duplicate data.
MP3 tags dialog will only pop up the first time you export as MP3; after that it will not pop up again as long as you have filled in at least one tag.
You can now add a label at the current playback position - in the Project menu, with a shortcut of Ctrl+M.
Clicking on a label now selects all of the tracks, making it easier to use the label track to recall selections.
Windows: Fixed a crash in the Time Track "Set Rate" command.
Fixed a bug that caused problems with recordings over 45 minutes on some Windows systems.
Mac OS X: Improved support for the Griffin iMic by fixing a bug that was causing it to always record in mono instead of stereo.
Added support for Software Playthrough (listen to what you're recording while recording it, or while monitoring using a VU meter) - this makes it possible, for example, to record using one audio device while listening to it play through a separate device.
Unix/Linux: Fixed freeze caused by captured mouse when audio device hangs. (Audacity may not respond, but it will no longer freeze all of X.)
Fixed a cosmetic bug that caused improper waveform display if you tried to open an Audacity project saved on a different platform (e.g., copying a project from a Mac to a PC).
Fixed bug that could cause instability when pasting, splitting, or duplicating a label track.
You can now change the font of a label track by choosing "Font..." from the label track's pop-up menu.
Basic printing support has been added. Currently it scales the entire project to fit exactly on one page. Try printing in landscape orientation for best results.
Mac OS X and Windows: Audacity ships with a newer version (1.0.1) of the Ogg Vorbis encoder. Vorbis compression will now have higher quality and smaller file sizes.
Fix a bug that occasionally caused crashes when applying effects to split tracks.
Zoom In / Zoom Out now properly disable when they're not available.
Always delete temporary files created by the "Preview" feature.
Other minor bug fixes and performance improvements.
Changes in 1.2.1:
* The following translations have been added or updated: Finnish, French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian.
* Fix a bug that could cause data to be lost when pasting audio from one project into another, after the first project has been saved and closed.

* Don't allow percentages less than -100% in Change Pitch/Speed/Tempo effects (fixes a possible crash).
* Fix a crash when the temporary directory is not available on startup.
* Correctly load ID3 tags saved in Audacity project files.
* On Linux and OS X, store lockfiles in the temp directory instead of the user's home directory. This fixes problems in lab environments where users have restricted or network-mounted home directories.
* Fix a bug that prevented Nyquist effects from running when certain regional settings were activated.
* Fix a bug in the Quick Mix command that could cause old temporary files to not be deleted.
* Linux: Fix endianness problems in playback on PowerPC.
* Linux: Fix compilation problem in Nyquist on MIPS.
* Linux: Include a more recent PortAudio v19 snapshot (fixes compilation problems when building with the --with-portaudio=v19 option).
* Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out."
* Other minor bug-fixes.
Changes since 1.2.0-pre4:
* New cross-fade effects.
* Fix problem where samples were drawn in the wrong position when zoomed all the way in. This caused the drawing tool to move a different sample than the one under the cursor.
* Don't use id3v2.4 tags, which are not yet supported by most players. (This was fixed in 1.2.0-pre2, but appeared again by accident in 1.2.0-pre3.)
* Correctly display translated messages in the status bar.
* When the cursor is on-screen, the Zoom In button now zooms to the area around the cursor.
* Mac OS X: Fixed audio problems on the Apple PowerMac G5.
* Linux/ALSA: Work around a bug in ALSA's OSS emulation that caused Audacity's playback cursor to move too quickly.
* Microsoft Windows: The Audacity source code should now compile out of the box on Windows.
* Many new/updated translations.

is no longer dependent on the wxWindows DocView
classes, so we can handle files ourselves. The
project file format is now text-based for easy
debugging. Eventually it will probably move to XML.
* Improved handling of wave tracks: as before, the data
is stored in blocks, but now, the blocks are correctly
limited to betweek n and 2n bytes each (for some n),
which guarantees editing operations always take the
same amount of time, while also ensuring that projects
don't get more fragmented over time.
* Rewritten user interface code. The shades of gray
are taken from the OS, and the project window has been
redesigned to have more consistent layout across all
platforms.
* Selecting "Open" now does the smart thing, opening a
project if you give it a project, or importing a WAV
file if you give it that.
