aaaahh...  Sync pulse direct recording is OK. See second track below, exactly 20 cycles, direct meaning with electrical connections between the board and my computer audio line in.

But acoustical coupling shows transients that will make postprocessing harder...

Acoustical coupling for board → speaker → mike → computer ADC

I'll rather try to shape the pulse with a gaussian on the SAMD21 to avoid those.
