And I really like fast answers. :) Thanks Dan!

I'll check them out now.

I like questions with easy answers:

Use Josh's PV_BufRd and PV_BufWr ugens. (In the JoshUGens in
sc3-plugins.) In fact he's written quite a few ugens around this
topic, PV_Freeze, PV_RecordBuf, PV_PlayBuf...

Hi all,

I've been scratching my head on this one, can't think of an easy way of doing this, maybe because my lack of command over the FFT implementation of SC, or maybe there is no easy way to do this at all without crafting an UGen
for it. Anyway here it goes:

I need a simple live phase vocoder, in which I can freeze magnitudes and phases (both) on demand, and I also want to be able to go back in time in variable time (so I need to save the old frames somewhere, and call them later on!). Unfortunately, I'm a bit clueless on saving all data to a buffer
and re-reading on demand part.

Any pointers on the subject will be appreciated.

Thanks,
Batuhan
