You have to decrypt the DVD first, then you can use Audacity
on the demuxed audio file. As I said you should have the
decrypting/ripping software output as demuxed audio and video.
It is that decrypted audio file that you edit with Audacity or other
audio software.
Even the old DVD Decrypter that comes with the Gordian Knot
download will do it in a couple of minutes. Any converter can
use the Lame MP3 encoding codec to turn your demuxed audio
into a .mp3 file in a few more minutes.
If you have www.VideoReDo.com you can use that on
the decrypted .vob, edit it and extract it to ES and even convert
the audio to .wav.
Luck;
Ken
