Spectral Freeze

A M4L Device that freezes the audio spectrum of any sound source. It uses jitter matrices to store a few frames of FFT values and continuously interpolates between them, generating a drone-like timbre that doesn't sound "frozen". Includes an envelope follower for automatic freezing and a feedback + crossfade control for the frozen matrices.

Based on the paper "A Tutorial on Spectral Sound Processing Using Max/MSP and Jitter" by Jean-Francois Charles (https://www.jstor.org/stable/40072649).
