All features

VST plugins support

ocenaudio supports VST (Virtual Studio Technology) plugins, giving its users access to numerous effects. Like the native effects, VST effects can use real-time preview to aide configuration.

Available in version 2 beta8 or higher (Microsoft Windows and Mac OS X)

Real-time preview of effects

Applying effects such as EQ, gain and filtering is an important part of audio editing. However, it is very tricky to get the desired result by adjusting the controls configuration alone: you must listen the processed audio. To ease the configuration of audio effects, ocenaudio has a real time preview feature: you hear the processed signal while adjusting the controls.

The effect configuration window also includes a miniature view of the selected audio signal. You can navigate on this miniature view in the same way as you do on the main interface, selecting parts that interest you and listening to the effect result in real time.

Available in version 2 beta7 or higher

Cross-platform support

ocenaudio is available for all major operating systems: Microsoft Windows, Mac OS X and Linux. Native applications are generated for each platform from a common source, in order to achieve excelent performance and seamless integration with the operating system. All versions of ocenaudio have a uniform set of features and the same graphical interface, so the skills you learn in one platform can be used in the others.

To assist ocenaudio development, a powerful toolset of audio editing, analysis and manipulation called Ocen Framework was created. ocenaudio is also based on Qt framework, a well known library for cross-platform development.

Multi-selection for delicate editions

To speed up complex audio files editing, ocenaudio includes multi-selection. With this amazing tool, you can simultaneously select different portions of an audio file and listen, edit or even apply an effect to them.

For example, if you want to normalize only the excerpts of an interview where the interviewee is talking, just select them and apply the effect.

Efficient editing of large files

With ocenaudio, there is no limit to the length or the quantity of the audio files you can edit. Using an advanced memory management system, the application keeps your files open without wasting any of your computer's memory. Even in files several hours long, common editing operations such as copy, cut or paste happen almost instantly.

Try it, you will be amazed!

Fully featured spectrogram

Besides offering an incredible waveform view of your audio files, ocenaudio has a powerful and complete spectrogram view. In this view, you can analyze the spectral content of your audio signal with maximum clarity.

Advanced users will be surprised to find that the spectrogram settings are applied in real time. The display is updated immediately when altering features such as the number of frequency bands, window type and size and dynamic range of the display.

Program works better and better... Greetings!

Review by clark on Jul 16, 2019 Version: 3.7.1 OS: Windows 10 64-bit Ease of use: 9/10 Functionality: 9/10 Value for money: 9/10 Overall: 9/10

I was so excited to find this software and instead of editing my recordings with my phone app, it was so much quicker to do it on my PC, unfortunately no one can read the files. so sad. I saw in the updates 3.6.2 fixes some issue reading MP4 files, but I guess it's not really fixed.

Review by Sharon on Apr 7, 2019 Version: 6.3.2, 64 bits OS: Windows 10 64-bit Ease of use: 10/10 Functionality: 2/10 Value for money: 10/10 Overall: 6/10

Good software but... why the feature "save as.." does not permit to specify at what bitrate I am saving the audio?
Why the program does not memorize the last used settings? Is it useful to save a file at 8kbit, by default???

Review by clark on Feb 27, 2019 Version: 3.6 OS: Windows 10 64-bit Ease of use: 10/10 Functionality: 7/10 Value for money: 9/10 Overall: 8/10

Excellent tool!
Thanks do the development team!

- I miss multi-track handling
- I miss FadingOut/In the Volume to/from e.g. 10% rather than 0% (or envelope tool)
cheers, radioMan
