I am currently working with a reel-to-reel recording of Neal Cassady. While listening to it, I notice that it seems to have an underlying track in reverse. When the interview runs out, there is still the sound reversal until the end of the reel. Does anybody know how this occurs or how I might listen to it?
Second thought (too obvious): a half-track mono recording played back on both output channels. Turn one off/down. Turn the tape over to hear the reversed track.
