@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.
