I wanted to do realtime audio FFT Filtering and could find no examples. Taking Python’s SoundDevice wire.py as my starting point, I created wireFFT.py [in GitHub as my WireFFT project https://github.com/joem5636/WireFFT]. I’m still working to make it more elegant and to add back my actual filtering, but it works with minimal delays and glitches [there is a brief startup glitch as buff fills].
