How to extract audio from an mp4 video file

for nam in filename.mp4; do nice mplayer -ao pcm "$nam" -ao pcm:file="$nam.wav"; done

Then, for example:

lame -b 192 -h filename.wav filename.mp3

Or:

nice oggenc -q5 filename.wav -o filename.ogg

Conversion to mp3 or ogg can also be integrated in the "for" loop above. See here: Howto: convert aac/mp4 to wav/mp3/ogg on Linux.
