It's quite easy:
Google for Virtual Dub Mod and then download it. Open your avi file with VDub Mod and click "Streams > Streamlist" . This will list all audio tracks of your avi file. Just click the right one and then "save as wave...."
That's it

If you want to convert it to another filetype, BeSweet would be a good porgramm. Similar program which is more easily to use would be Headac3he. It will convert your AC3 stream into pcm wave/mp2/mp3 or whatever you prefer.

If any further questions.. ask! cause might know some things you need

Sure. You export the sound as I have mentioned it above.
Then you use Headac3he or BeSweed to get rid of the AC3 and output a wave file.

If you succeeded, the wave file will be about 900mb. Okay, then open Virtual dub (not mod, cause I don't really know how to do it with VDub mod) and select "Video > Direct stream copy" then "Audio > Wave audio" and select the wave file outputted by Headac3he/BeSweet. When the wave file is loaded, click "Audio > Compression" and select something like mp3 (or whatever you prefer) and the bitrate you'd like to have.
When finished just click "File > Save avi" and save the avi

What's the sense? You'll have normal mp3 audio instead of ac3 audio in your avi file. the picture quality will be 100% the same cause you've previously selected direct stream copy on video. so just the audio gets reencoded.

hope you get what I mean.

Thanx!

Edit: Headac3he tells me that there's not enough space on destination drive when I try to convert but there's like 25 Go...

Hm... shouldn't be that way. Did you DL all dlls you need?

Or try besweet instead if Headac3he doesn't work probperly.

I normally need 15-20mins for the whole decoding (just for info).

I don't know what was the problem... But I just directly extracted the AC3 file from the video and converted it to wav... seems to work..

Edit: Virtual dbu is telling me this message:

No audio decompressor could be found to decompress the sound format

Do I miss a dll or something? Plz help

They have all you need. And a german forum with english spoken topic to.
I think you need the AC3 filter, maybe you need a codec. G-Spot is the best tool to check your codecs.
