fxrapt - fundamental frequency estimation by Robust Algorithm for Pitch Tracking
(-i item) (-l) file
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.
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.
