/**
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.
</para><para>
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. </para><para>
