[linux-audio-user] Mystery first "track" on many CDs?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,

I'm batch-ripping and encoding a lot of my CD collection to
put on my mp3 player.  I've noticed that a number of CDs contain
an apparently spurious first track that's apparently very short
(about a tenth of a second) and contains no audible signal. 
What the heck is the point of this track?

e.g.

$ sndfile-info track00.cdda.wav 

Version : libsndfile-1.0.11
