hello there! I'm trying to make a small app that detects the pitch of what you say in the microphone (and possibly do something with it). I managed to get the volume, but I can't figure out how to get the pitch. any ideas? I'm on c#, btw.

You can apply a fast fourier transform to the buffer data to determine the frequency (pitch) spectrum. If you're interested in a particular pitch, you can search the spectrum for a peak around that frequency.
