# Pitch Detector

JUCE module for pitch estimation

PitchYIN class based on the YIN implementation found in the [aubio](https://aubio.org) library

PitchMPM class adapted from the McLeod Pitch Method implementation in https://github.com/sevagh/pitch-detection

The updated version of the PitchMPM class now uses FFT for the auto-correlation function using the AudioFFT library (via the module wrapper at https://github.com/adamski/audio_fft). The previous time-based version is now in the `time-based` branch. 

### Usage

**NOTE:** `bufferSize` should be a power of 2!

```cpp

// Class members

PitchMPM pitchMPM;     

AudioSampleBuffer sampleBuffer;

// Setup / prepare

pitchMPM.setBufferSize (bufferSize);

pitchMPM.setSampleRate (sampleRate);

// Process

float newPitch = pitchMPM.getPitch (sampleBuffer.getReadPointer (0));

```

### TODO

- [ ] Seperate time-based method into another class that can be used as an alternative to the FFT based method

- [ ] Add FFT based YIN implementation (not a priority, MPM works well for my needs - PR's welcome)

- [ ] Create base (virtual) `Pitch` class and add implementations as subclasses.  

- [ ] Add other methods, e.g. Wavelet? 

- [ ] Remove JUCE dependency from implementations so that they can be used on embedded platforms, e.g. Arduino/Teensy. Will also need 'pluggable' FFT methods for this to work.
