Details on ESPS' get_f0 function work

Started by Dims March 19, 2010
Hi!

I am experimenting with pitch analysis with the help of ESPS.

Can anyone give a few hints?

I cannot find in manuals here
http://www.ee.uwa.edu.au/~roberto/research/speech/local/entropic/ESPSDoc/manpages/indexes/index.html
about in what amplitude range a processing signal should be? 

Should it be [-1,+1] or [0,1] or [0,32767] or it does not matter?

And what the rate of output samples will be returned?

Thanks.
