Yes, thank you Paul, I looked at the spec on Amazon where I purchased it an it said 3.3v and I assumed that was it. I am still trying to get the spectrum analyzer composited but I'm impressed the port from FastLED to Octo library is a huge improvement in the framerate. It looks much better.
So for some reason I was thinking I could connect the mic using PWM and select any pin. Now after reading my last working configuration was Pin 16 (A2) on the Teensy 3.6. Now on Teensy 4.0 it seems that pins 15 and 16 need jumpered? In the Octo schematic they are not available?
