autocorrelation code for full signal |
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!

I don't see a question about the C++ language in your post. Please
understand, the fact that you plan to write a particular program in
C++ does not make this a C++ language question.
I would suggest you ask about this in news:comp.dsp, since what you
are asking is for an algorithm to do what you want, and they are the
experts.
Once you have selected an algorithm, if you have trouble coding it in
standard C++, this is the place to post problem code and ask for help.
