@section synopsis Synopsis

@SYNOPSIS@

pda is a pitch detection algorithm that produces a fundamental frequency
contour from a speech waveform file. At present only the
super resolution pitch determination algorithm is implemented.
See (Medan, Yair, and Chazan, 1991) and (Bagshaw et al., 1993) for a detailed
description of the algorithm.

The default values given below were found to optimise the performance
of the pitch determination algorithm for speech data sampled at 20kHz
using a 16-bit waveform and low pass filter with a 600Hz cut-off
frequency and more than -85dB rejection above 700Hz. The best
performances occur if the [-p] flag is passed.

Pitch detection on typical male voice, using low pass filtering:

    $ pda kdt_010.wav -o kdt_010.f0 -fmin 80 -fmax 200 -L
