Thanks Monty.  I'm mainly interested in pre-gap info so I can
determine what rubyripper is doing with pre-gaps.  EAC appends them to
the previous track by default, and that is the "format" AccurateRip
uses to generate its checksums.

Do you know of any way to determine if a track has a pre-gap (even
just a couple seconds of silence) or not without listening to each
track on a CD player?
