I used a script like this (I just rewrote it from the top of my head, so
this one is untested):
EXT="mp4"
DEST="/home/michael/music"
for F in *.${EXT}; do
N=${F/$EXT/wav}
mplayer -vc dummy -vo null -ao pcm -aofile "${DEST}/${N}" "$F"
normalize "${DEST}/${N}"
lame --verbose -q 2 --abr 192 "${DEST}/${N}" "${DEST}/${F/$EXT/mp3}"
done
The catch with this over-engineered and occasionally inefficient script was
that I would use it for both random audio formats and video files to extract
the audio track (think presentation-to-podcast-like conversion).
