Set up a sig genny and test him out


Much easier to say the test tape is stretched.
Perhaps perfect pitch testing would only work by playing the likes of JSB
Tocatta and Fugue in D major, not pure tones

Has anyone ever heard of a tape stretching enough to be detectable?
I find that very hard to believe. Far more likely that the motor's
speed control is off.

Do you have another deck you can use? Record 5 minutes on the reference
deck and then compare the time to play the same on the test deck.
I've used a CD recording and then played the CD at the same time as
playing the tape on the test deck. If they fall out of sync then the
test deck is running at a rate different than the reference deck.
