Basically cd audio tracks have a base sector and a start specified. That allows sectors representing audio before timestamp 0:00 to be represented the track.

Basically cd audio tracks have a base sector and a start specified. That allows sectors representing audio before timestamp 0:00 to be represented the track. The reason for this originally was probably to allow the drive to get synchronized before the track started. Enterprising cd masterers put actual hidden audio data in that area which would allow you on some CD players to rewind past 0:00 and then play the hidden audio at the negative timestamp.
- crazygringo 2y agoHow much hidden audio could be stored? Was it limited to something negligible like a couple of seconds? Or could you store a whole five-minute recording in there or something?
- boomboomsubban 2y agoThere doesn't seem to be a limit, this https://en.wikipedia.org/wiki/List_of_albums_with_tracks_hidden_in_the_pregap https://en.wikipedia.org/wiki/List_of_albums_with_tracks_hid... mentions a 27 minute live recording.
- jvan 2y agoIncredible! Songs in the Key of X was the only album I ever knew to do this, and it wasn't even the first. I had no idea so many others did the same thing. Edit: Son of a *, I've had a copy of Sister Machine Gun's Burn for almost 30 years and never knew there was a hidden track!
- ChrisArchitect 2y agoClassic X-Files album is the one I think of too. And how they hinted to everyone that there even was a hidden track on the sleeve: "'0' is also a number". (and the technical fineprint about the disc possibly not being Redbook compliant)
- croes 2y agoI guess the limit is some milliseconds short of 74 minutes.
