I am trying to implement an FFT Spectral Freeze patch based on "A Tutorial on Spectral Sound Processing Using Max/MSP and Jitter", Jean-Francois Charles. In the project, Charles uses the jitter objects to solve this.

I am starting to play around with some ideas, but I was wondering if this is implemented somewhere.

What is interesting in these patches is that the spectral freeze is dynamic so it sounds more organic.

any thoughts?
