light-pitch-detect

This light-pitch-detect uses MPM method, which is extracted from sevagh/pitch-detection. It is light, no heavy dependency and easy-to-use.

The only dependency is anthonix/ffts. The windows binary of ffts has been uploaded to this repo, so no need to compile ffts. For other platforms, it needs to compile locally.

The api is ready, all you need is to include api/pitch_api.h, then invoke like this:

float pitch = pitch_get(audioBuffer, buffer_size, sample_rate);
