    Reduce Audio Sampling Bandwidth for FHT/FFT

    Experts, 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...

    Frequency Analysis Fun, Low-end "Noise"

    So, 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...
