# Demo script for processing all audio tracks with a mp3 decoder
# based on a news article by Tom Kludy

# wav files (see cdda2mp3.new).

# usage: cdda2mp3 <name prefix for all mp3 files>

# list_audio_tracks is a (symbolic) link to cdda2wav
# and used to generate a list of audio track numbers and start
# sectors, which in turn are used in a loop to spawn cdda2wav
# and the post processor on a track by track basis.

# specify the sampling program and its options
