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