Fast Python implementation of the Yin algorithm: a fundamental frequency estimator.

Based on the article:

[1] De Cheveigné, A., & Kawahara, H. (2002). YIN, a fundamental frequency estimator for speech and music. The Journal of the Acoustical Society of America, 111(4), 1917-1930.

All the functions in the code correspond to steps in the article [1]. Meanwhile, the difference function has been modify substantially in order to improve speed. Finally, speed has been improved by more than 1000x.

• Numpy
• Scipy
• Matlplotlib (for graphing)

$python yin.py

All parameters (i.e frequence min, frequence max, harmonic threshold) in the yin.py function should be adapted to obtain good results. See the article [1] for more details.
