Disregard consonants and noise

deerell — Wed, 21 Dec 2011 23:20:21 +0000

I’m working on a pitch tracker using sigmund~, and I’m getting some weird readings from consonants. What are some ways that I can filter these sounds out of my signal, or get my patch to ignore them?

Tristan Jehan’s analyzer~ object has a brightness and noisiness outputs that might help you identify some of these spots, and ignore them. You might as well use that as your pitch tracker, too. Or, re-write sigumund to give you some of that data.

…and I’ve seen implementations which use [zerox~] –> [>~ 8] to identify noise/consonants, opening/closing a [selector~]. Probably need to experiment with the > value.

Since a lot of the noise and consonants are in much higher frequency ranges than vowels, the most simple solution is maybe a corresponding Highpass filter.
You could gate the incoming sound, so it gets cut if the highpassed signal has a certain amplitude.
