For a speed calibration tape record a 3khz sinewave on your quartz locked deck. Then you can set the speed using either a frequency counter, a spectrogram app, an oscilloscope or wfgui. The advantage of using wfgui is you can test for wow and flutter as well, given your recording deck has low w&f itself. wfgui is free software you can find online.
@@kovutlk I don't like the sound of a 3khz tone, but I do want to experiment with wfgui, thanks. I'd rather use my method for speed calibration, but wfgui would be good for wow and flutter, thanks.
@@AvidRetro Actually, that was the primary reason I looked for one in the first place. I now have two C-10 cassettes for that purpose (forthcoming video).
I remember this era of MSX games.
@@Retroaria I never had an MSX compatible computer. I'll look into them.

Games and telephone answering machines frequently used 15 minute tapes.
I forgot about answering machines.
I have found using one of these shorter tapes is a good way of exercising an old auto reverse walkman :)
