Back in pippi-land, I’ve got a branch started that integrates some of the modules from Paul Batchelor’s Soundpipe into pippi: https://github.com/luvsound/pippi/blob/soundpipe/pippi/soundpipe.pyx
So far: lowpass, highpass, bandpass, and band reject butterworth filters; a compressor; saturation distortion & dc blocking.
Next up probably is paulstretch, and using the mincer module as an option for pitch shifting without time change / time stretching without pitch change (right now there’s a basic granular implementation) and taking advantage of the bandlimited wavetable generators (plus possibly the osc and oscmorph 1d & 2d oscillators to replace my current roughshod implementations) but there’s lots more too…
