Release Name: avitoac3 v1.0.5.0 Hide changelog Notes: Changes: Improved single file encoding with fewer steps. Eliminated temporary wav files. Now I'm piping output from wavi directly to aften. Release Name: Avi To AC3 v1.0.4.9 Notes: Changes: Added ini file to remember settings. Added Program Setup tab to change programs path if installed in any other directory than default. Cleaned up batch files. Removed pskill.exe and replaced it with native windows taskkill to abort the process. Removed SSRC.exe because of problems with Vista UAC and replaced with ssrc in temp avisynth file. Version 1.0.4.8 Bug fix. Terminate Process button wasn't working. Now fixed. Version 1.0.4.7 Added support for mpeg audio conversion. Useful for converting VCD mpeg with mpa/mp2 audio to AC3. Version 1.0.4.6 Added Single file processing. Version 1.0.4.5 Added Process log window. Completely hid the dos screen and redirected the output to the log window. Added button to save log window contents to a text file. Added terminate process button. Version 1.0.4.4 Added button that opens the online guide in a web browser. Version 1.0.4.3 Updated Sox to version 14. Now has mono wav merging functionality. Removed wavavimux. Cleaned up the batch files some more. Version 1.0.4.2 Fixed bug in temp. created avs file. Avs file was creating wrong directory. Fixed now. New in version 1.0.4.1 Fixed file size bug in temp created 6 channel wav. Removed interlx Added wavavimux New in version 1.0.4.0 Simplified GUI by removing Extract to Wav button. Now all that is needed to do is just select directories, select ac3 bitrate and select your form of ac3 encoding (2 channel, Upmix, or 5.1) then press start. Replaced Avisource with DirectShowSource() to the avisynth scripts created by avi to ac3 which should allow for extraction of 2 channel ac3 from avi's for upmixing. Added a more visible guide to the end of the installation process as well a pdf guide in the program files directory. New in version 1.0.3.9 Bug fix Removed requirement that OS has to be installed on c: drive. App should now work if your "program files" directory is on a drive other than c: New in Version 1.0.3.8 Tweaked the batch files some more. Fixed Typo in the gui. New in version 1.0.3.7 Improved batch process. Added cleanup of temp avs files created by avi to ac3. Removed the Resample audio button but left dither control. App will now run ssrc on all created wav files. New in version 1.0.3.6 Updated aften to version 0.08 Added AVITOAC3_ to the avs files created by the app to prevent possible overwriting of already existing avs files. New in version 1.0.3.5 Removed one extract wav button. Now one button serves both functions. Added Upmix function taking 2 channel input and outputting 5.1 Ac3. Uses Sox, Soxmix, and interlx to create a 5.1 wav from a 2.0 wav. Added 5.1 AC3 output from 5.1 source

Okay danielk68 I think this may help you. First if you want to upmix an avi containing a 2 channel ac3 to 5.1 ac3 you will need to create an avisynth script for it using directshowsource("d:\whatever\youravi.avi") as avi to ac3 dosen't handle ac3 decoding natively without it. Follow these steps exactly. 1. Select source directory . 2. Select the directory you want your ac3 files to be output to. 3. Press "Extract Wav from AVI or AVS" 4. Optional. Add dithers (noise shaping) if needed. 5. Select your AC3 bitrate 5a Press this if you are just doing a 2 channel AC3 encoding. 5b Press this if you want to upmix 2 channel source audio to 5.1 AC3 5c Press this if your source audio is already 5.1 and you want to encode to 5.1 AC3 6. After making your settings press start This is all documented in the guide that was included in the setup file. You can also find the guide here http://forum.videohelp.com/topic338084.html#1760733 For problems, request, or bug reports please use the development thread. http://forum.videohelp.com/topic338084.html

Ok, It's Works Now Even if my o.s it's not on c:/ Drive. But it,s not a 1 click tool, First You Have To Extract The Sound To a Wav File By Clicking The "Extract Wav To...", Then You Have To Choose Your Choice, Upmix ,2 or 5.1 Channel Etc. When Extracting To Wav, The Final Result It's Not Saved On The Destination Directory, And At The End Of Process, The Wav File Result It's Deleted!!! (the App Made a Batch File, So i Manually Removed The Deletions Steps and run it again). Same Issue occurs, When Choosing Upmix, 2 or 5.1 Channels, without an option to use these Temporary Files. I Couldn't made a 5.1 channel audio file, from an ac3 2 channel file. is it because i have a 2 channel sound card, or because another issue? (a mini guide will be useful. what Dither Means?)

This Tool, Has a Very Big Potential. I Couldn't Make It Work, Because my O.S It's On My D:\ Drive And Not On C:\ As Default.The App Didn't Run For Me Because Of that. (App is Looking For Something On C:\programs Files\....) (No Forums To Report That Bug) When Fix This, i'll Report Another Post.

Volume drop with ffmpeggui (which is an older version of ffmpeg under the covers) ? Ah ! So that's what's been happening. Now I/m a happy chappy. Off to look at aften as I want to do stuff in a batch file via command lines ...

I don't think the previous poster really understands what this app is for. It is not for re-encoding ac3 audio from avi files. It is for taking avi files with other audio (mp3, mp2, etc.) and extracting to wav, resampling, then encoding to ac3 in a batch process. It does in one step what otherwise takes several steps with different apps.... with the exception of ffmpeggui. One advantage of this over ffmpeggui is that this uses aften for the ac3 encoding so it's faster and you don't suffer from the volume drop that you would get with ffmpeggui..

I'm wondering if this program is really necessary to create DVD compliant AC3 audio. The main reason why AC3 audio ripped directly from an AVI isn't DVD compliant, is because there are junk/partial frames at the start of the AC3 file. For example, Nandub's "Save wav" option adds a 58 byte artificial wave header, which has to be removed before it's DVD compliant. This can easily be done within a few seconds with the program DelayCut. VirtualDubMod's Stream list -> Demux option doesn't add junk at all to the AC3 audio, unless it has a positive audio delay. But then you can use DelayCut to remove it as well. So in most cases it isn't necessary to reencode the AC3 audio file in order to make it DVD compliant.

Hmm, didn't try it. Wondering why use this over (1) ffmpeggui - maybe because it isn't updated that often (2) a simple ffmpeg command line in a baych file with parameters (2 channel in this case)_ "C:\SOFTWARE\ffmpeg\ffmpeg.exe" -i "%InputAVI%" -ab 192k -ar 48000 -ac 2 -acodec ac3 -y "%OutputAC3%" ?
