4.3.1 pitchextract

pitchextract is used to extract the fundamental frequency contour from monophonic audio signals. A simple sinusoidal playback is provided for playback of the resulting contour. In the following example, the pich is extracted from soundfile, using a windowsize of 1024 (-w 1024), a lower pitch of 36 (-l 36) and an upper pitch of 128 (-u 128).
