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).
