I am looking for a way to use the standard arduino FFT (no FHT for non-AVR) but only for a small section of the audio spectrum.
Instead of breaking down the entire spectrum, resulting in wide bins even after /2, I'd like to only sample 2 or 3kHz of the spectrum, and thereby have a more...
For a hobby project, I'm making a spectrum analyzer using an 8 bit datapath in a MCU.
I wanted to learn more about how the FFT/FHT works, so I am taking a stab at my own attempt at both an FFT and FHT. I have both an 8bit forced datapath FFT and FHT "working" in python, and it's...
