Pitch detection method

Variants

Schmitt

Schmitt trigger

This pitch extraction method implements a Schmitt trigger to estimate the period of a signal.

This file was derived from the tuneit project, written by Mario Lang to detect the fundamental frequency of a sound.

See http://delysid.org/tuneit.html

Fcomb

A fast harmonic comb filter

This pitch extraction method implements a fast harmonic comb filter to determine the fundamental frequency of a harmonic sound.

This file was derived from the tuneit project, written by Mario Lang to detect the fundamental frequency of a sound.

See http://delysid.org/tuneit.html

Mcomb

Multiple-comb filter

This fundamental frequency estimation algorithm implements spectral flattening, multi-comb filtering and peak histogramming.

This method was designed by Juan P. Bello and described in:

Juan-Pablo Bello. “Towards the Automated Analysis of Simple Polyphonic Music”. PhD thesis, Centre for Digital Music, Queen Mary University of London, London, UK, 2003.

Yin

YIN algorithm

This algorithm was developed by A. de Cheveigne and H. Kawahara and published in:

De Cheveigné, A., Kawahara, H. (2002) “YIN, a fundamental frequency estimator for speech and music”, J. Acoust. Soc. Am. 111, 1917-1930.

See http://recherche.ircam.fr/equipes/pcm/pub/people/cheveign.html

Yinfast

YIN fast algorithm

This algorithm is equivalent to the YIN algorithm, but computed in the spectral domain for efficiency. See also python/demos/demo_yin_compare.py.

Yinfft

YIN fft algorithm

This algorithm was derived from the YIN algorithm. In this implementation, a Fourier transform is used to compute a tapered square difference function, which allows spectral weighting. Because the difference function is tapered, the selection of the period is simplified.
