Here is a simple, slow example of the DFT that demonstrates how to calculate the band-limited power spectrum.

Thanks for the code. I think it be very slow on an ATmega2560. I was considering moving to one of the ARM based processor such as a Teensy 4.1 where its speed should be ok. I'll give it a try when I move processors.
