Real time pitch detection

by

Taking a step back… To get this working you MUST figure out a way to plot intermediate steps of this process. What you’re trying to do is not particularly hard, but it is error prone and fiddly. Clipping, windowing, bad wiring, aliasing, DC offsets, reading the wrong channels, the weird FFT frequency axis, impedance mismatches, frame size errors… who knows. But if you can plot the raw data, and then plot the FFT, all will become clear.
