+   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.
