Hi everyone,

i wondered if someone made a patch measuring the PHASE of a reference signal compared to measured signal

Hi,

you could one of the cross-correlation externals to measure the time delay between 2 signals. (there's one external in iem_tab from pd-extended I remember and there are possibly more). If that's useful for you I created a similar, fft based patch using vanilla objects I can post here.

However correlation doesn't directly measure phase differences of separate frequency bands but the delay of the signal over all frequencies.
