Re: tuning without detents


Hi Jerry,
I've actually thought about the idea of implementing an actual audio filter in the software. One of the later ARMs such is used on the Teensy 4.2 is well able to do that in its sleep.

But generating an 80kHz square wave to drive an SCAP would be trivial for an ARM, yes, but I'm mystified... are you using a filter to turn a square wave into a sinewave? Could you elaborate?
