If you want it without being mp3 compressed try this mplayer $avi -vc null -vo null -ao pcm:fast:file=$wav

I did a batch operation on multiple files with for file in `ls -1`;do mencoder "${file}" -of rawaudio -oac mp3lame -ovc copy -o audio/"${file/%avi/mp3}";done assuming audio/ directory has been created beforehand. This is simply an awesome one-liner. Thank you for sharing this!

Two things i've learned using this: 1) using mencoder is faster than "mplayer -audiodump"; the latter will play the entire video in normal speed as it dumps the audio. 2) If your files have spaces on their names use: $ for file in *; do mencoder "${file}" -of rawaudio -oac lavc -ovc copy -o audio/"{file/%avi/}mp2";done
