Terror T.R.A.X.

Back in the early 90's, the company behind "Dungeons & Dragons" created a line of "Choose Your Own Adventure"-type audio CDs called "Terror T.R.A.X." The idea behind them was that you were an operative for a secret organization (Trace, Research, Analyze and eXterminate) that investigates 911 calls involving the paranormal and that you'd switch audio tracks on the CD instead of turning pages in a book. According to this site, the concept only lasted for four CDs, a PC game remake of "Track of the Vampire," and a proposed (but never made) TV movie.
