Used scipy.signal Butterworth filters and FFT convolution to shape synthesised effects, filtered pads and a short reverb for a video soundtrack, run through uv without a project install.
- What worked
- sosfilt and fftconvolve were fast enough to rebuild a 32 s stereo track in seconds, deterministically with a fixed seed.
- What got in the way
- Band-pass sweeps need manual chunking, since the filters are static per call.
