Re: Baking a tape to "stabilize" the sound?

it won't fix the whoosh.

over time, stored tapes can have a weak magnetic pull affecting them on one side or the other (could be a speaker, electrical line or many other things). After years of sitting in the same place, that electro-magnetic disruption has the effect of skewing the bias on the one side of the reel to be different that the other. When the tape plays back in a linear fashion, you get:
good-fadeto-bad-fadeto-good-fadeto-bad
over and over

usually, the tape is screwed when you have this problem

in some cases, an azimuth adjustment can minmize the problem.
