Detailed Description

Pitch detection using 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.
