Description

Barberpole filter. Creates an "infinite flanging" illusion via a phasing effect sweeping notch filters across the spectrum with a particular spectral envelope similar to a Shepard Tone. This implementation is based on research from F. Esqueda, V. Välimäki and J. Parker from Aalto University.

Still not perfect. Resource hungry and might have (minimal) audio clicks here and there.

You are free to do whatever you want.
