Best free avi to mp3 converter/extractor?

[SoulAssassin]

I'm looking for a freeware app to rip the audio from a bunch of avi files (concert footage) to mp3 files. Everything I've found either doesn't work right or has an X second limit and wants you to buy the full version, google has failed me for one of only a few times. Something I can point to the dir and let it run on all the files in batch would be awesome but if I have to do them one at a time I'll deal with it.

Try this...
http://avidemux.sourceforge.net/

I had a real simple one for Windows, but I can't remember what it was called. It didn't do batch processing, but individual use couldn't be much easier.

Edit:
Batch processing using Avidemux...

Sweet...for posterity the cmd line was:

set avidemux="C:\Program Files (x86)\Avidemux 2.5\avidemux2.exe"
for %%f in (*.avi) do %avidemux% --load "%%f" --audio-process --audio-normalize --audio-resample --save-uncompressed-audio "\mp3\%%f.mp3" --quit

Thanks for the update, and I'm glad you got it working. I have it installed, but I haven't had to use that since I've been running Ubuntu. I was still on Windows last time I had to separate audio from video.
