digiology

I have a patch which stores fft data in four buffers and plays it back in real time. I want to freeze the contents of the buffers with the patch continuing to re-synthesize that data.

If you try my patch below it attempts to do this but when clicking the toggle in the top right it'll freeze the sound but there is obvious amplitude modulation.

There are a few excellent patches on spectral freezing which use jitter to create a sonogram analysis of fft frames, which is then used to re-synthesize the audio.

They are by Jean-Francois Charles and available here:

Your patch looks cool , I find the concept of freezing sound really intriguing. I actually quite like the AM as well, but I can see that it's not desireable for most things!

I may have time tomorrow to look at your patch, a new way to freeze sound is always interesting!
