Hi Guys,
I’m wondering if anything has been done in the way of converting audio directly to PWM
and playback with hardware PWM? Or am I on my own?

Recording either analogue input, or digitising to 1 bit and counting frequency directly.
I’m going to try the latter first.

I know about RB’s pic sound playback, but IIRC the PBP implementation could not be fast enough.
Cheers, Art.
