FXRAPT

NAME

fxrapt - fundamental frequency estimation by Robust Algorithm for Pitch Tracking

SYNOPSIS

fxrapt (-i item) (-l) file

DESCRIPTION

fxrapt is a program to perform fundamental frequency estimation algorithm using the normalized cross correlation function and dynamic programming. The algorithm implemented here is similar to that presented by B. Secrest and G. Doddington, "An integrated pitch tracking algorithm for speech systems", Proc. ICASSP-83, pp.1352-1355. It is fully described by D. Talkin, "A robust algorithm for ptich tracking (RAPT)", in W. B. Kleijn & K. K. Paliwal (eds.) Speech Coding and Synthesis, (New York: Elsevier, 1995).

This algorithm was originally used in the "get_f0" program of ESPS.

LICENCE

Some code in this program was originally written by David Talkin and Derek Lin as part of the Entropic Signal Processing System and is used under licence from Microsoft.
