A small collection of pitch tracking algorithms in C
A transparent discovery signal based on current public GitHub metadata.
This score does not audit code, security, maintainers, documentation quality, or suitability. Verify the repository and its current documentation before adoption.
Pitch tracking methods:
- Zero crossing rate estimator
- FFT with Quadratic Interpolation (QIFFT)
- Autocorrelation
- Average magnitude difference function (AMDF)
- YIN estimator
Technical notes: - Correlation methods are computed in the frequency domain with FFT - Implementation relies on the kissfft library (MIT licensed) - Tests (to be added) rely on libsndfile (GPL licensed)
