Spectral Filterbank

About

Spectral Filterbank is a multi-effects plugin by Michael Norris. It applies real-time spectral processing to audio from static files or live streams. Most of its effects convert audio into the frequency domain with a Fast Fourier Transform algorithm. In that domain, the sound can be smeared, blurred, granulated or frozen.

What it sounds like

Large FFT sizes can produce smooth, ethereal drone textures.
