autocorrelation code for full signal

Started by Unknown December 7, 2007
Hi:

i got the source code of autocorrelation  (AC) for a frame (for
example: 600 samples out of 40000 samples) of a signal. Can anyone
show me the AC code for the whole 40000 samples which means
continuosly analyse every  600 samples up to the 40000th samples, so
that the result would be stored in an array. i need this for pitch
tracking.

or can anyone give me a better idea on doing the pitch tracking,
showing the pitch of a voice in graph form.

thanks in advance!
