fxanal - estimate fx from sp using autocorrelation and tracking
(-i item) (-f) (-X) file
estimates FX from a speech waveform by autocorrelation.
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.
and their meanings are:
Identify program and exit.
Select input item number and type.
Use LX signal as source. Some processing is modified for LX signals.
Modify default settings to improve the decoding of high-pitched voices.
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
FX estimate by autocorrelation.
