I'm fiddling with a fun little oscillator with an additive flavour, but so far I've done all the processing on the frequency of the incoming midi signal.
now I want to use the same gui and code modules but apply it to incoming audio. However, all the math I throw at the audio stream deals with levels, not frequencies, so it doesn't work like I expect it to.
So.
Simple, basic question:
How do I take an audio stream and fiddle with its frequency?

fundamental frequency detection is not a simple basic thing 🙂 a common method is autocorrelation (http://en.wikipedia.org/wiki/Autocorrelation) for a more basic, brute-force method you could try lowpassing the signal at a low frequency, distort it as hell, and then count the time between zero crossings to detect the fundamental period.
