Nice one, I finally made a phase-vocoder based time freezer, inspired to a variety of Electro-Harmonix effects.
We'd like to have a library of effects among the examples, these should be mostly about the DSP and as less as possible about interfacing with it, with a clear interface so that they can be easily re-used by others as building blocks.
It is going to be challenging to find the appropriate format, though, and my TimeFreezer, for one, is nowhere close to these specs as of now, but if anyone is interested in contributing or pitch in as to what format it should have, feel free to do so.
I will open a dedicated thread later, but I am leaving this as food for thought ...
