I’ve been experimenting with pitch~ in conjunction with a mic input to find the F0 of the incoming signal. The problem I have is it will give an accurate result then flip to a strange one just when I don’t need it to. I’ve tried outputting the results when there’s a sound above a certain threshold but I can’t eliminate the problem.

I was wondering, since I’m recording the incoming audio to a buffer if there’s any objects or processes that can tell me the F0 in non-realtime?

Here’s a patch that shows many different methods for smoothing data, have a look and perhaps implement one that works well for you.

Thanks for that, it is *very* interesting and useful. Will help a lot with things like Arduino input. Your patch has a great layout that lets you easily compare and understand the many ways of doing smoothing. Kudos!

The [lbyl] external from CNMAT might also be worth a look.

Speaking of that, I’m working on a better pitch tracker, based on a fast lifting wavelet transform. It’s some months away yet, but it is much less jittery than other methods I’ve tried.
