gordguide - this is what I want to do, do you know of a program that will do this?To create hidden tracks (ie negative track number) you need a program that allows you to control where the index markers go. Combine (for example) 2 audio tracks into a single track with an audio editor. Then, set the 01 index marker to a point after the first song ends. There is no "00 index marker" in the CD redbook standard.
My first song, 3 minutes
Blank space (not space between tracks, but encoded as silence) 2 seconds (for convenience, makes it easier to find a truly silent place to point the index marker to).
My second song, 3 minutes.
All above encoded as one track.
Set 01 index marker to 3 minutes 1 second.
The user now has to hit the back button when the "second" song plays to hear the hidden "first" song. The hidden song will never show up in the CD player's table of contents.
