FXANAL
NAME
fxanal - estimate fx from sp using autocorrelation and tracking
SYNOPSIS
fxanal
(-i item) (-f) (-X) file
DESCRIPTION
fxanal
estimates FX from a speech waveform by autocorrelation.
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.
Options
and their meanings are:
-I
Identify program and exit.
-i item
Select input item number and type.
-l
Use LX signal as source. Some processing is modified for LX signals.
-h
Modify default settings to improve the decoding of high-pitched voices.
-X
Run extra check for "pitch halving", where the chosen Fx is exactly half
the correct answer. Only use this if you are having problems with pitch
halving.
INPUT ITEMS
1.xx
Speech waveform.
2.xx
Laryngograph waveform.
OUTPUT ITEMS
4
FX estimate by autocorrelation.
