Unfortunately, there are 2 versions of this. The other is here: https://github.com/endolith/waveform-analyzer I intend to either completely combine them or completely separate them, eventually.
Somewhat crude THD+N calculator in Python
Measures the total harmonic distortion plus noise (THD+N) for a given input signal, by guessing the fundamental frequency (finding the peak in the FFT), and notching it out in the frequency domain. This is a THDR
