yes, it adds only very little latency

i am not shure either. probably you (and wikipedia) are right,
and autotune uses a phase-vocoder. using millers phase-vocoder with
small window-sizes sounds awfull though. but maybe, with
waves which are already periodic (like single cycles) it is possible
to do without windowing and short fft sizes (like 128 or even 64).
i will try this when i have found a way to extract
single-cycle waves from audio input in pd...

bis denn!
