i've written at least 4 different pitch detection algs in my life for
at least 3 different parties. i don't know everything about the
subject, but most terms regarding pitch detection (or "pitch
estimation" if that's what you want to call it) are something that i
have read about and have an idea what the term means. but i have
never heard of "pitch prediction gain". i just don't know what that
is. and, although i have an idea of what pitch prediction might mean,
i am not sure what the application is. most (or all) pitch detectors
have a *delay* from when a note begins and the algorithm has enough
data to confidently determine and report the pitch. decrease that
delay (prediction?) will certainly increase error and the likelihood
of bad pitch estimation decisions.

FWIW.

Hi,
I hope to pitch prediction gain between two pitch estimation
algorithms. Does anyone here have a software to compute pitch
prediction gain or show me how to calculate pitch prediction gain?
Thanks in advance!
