[linux-audio-user] Extracting/Ripping tracks from DVD-Audio discs

[D. Sen]

The problem with all of these applications is that they downmix the 
audio down to stereo when storing to a wav file.

Do you know if the tccat/tcdecode/tcextract command will save the 
individual tracks (interleaved or otherwise)?

Thanks,
