Re: How to set the speed on cassette decks.
The official way to do it is to use a manufacturer's reference tape and a lab grade frequency counter. I don't have either of those, so this is how I do it:
1. Generate some some sine wave tone using software, and save it as a WAV file.
2. Burn the WAV file to an audio CD.
3. Record the CD onto a cassette using a known good recorder.
4. Play the CD on a player while playing the cassette on the player needing adjustment.
5. Adjust the speed for a zero beat between the two.
Domestic deck speed stability isn't great and it can be difficult to find the exactly correct setting, but you can get very close.
