Confusion about linear prediction within flac
Hi,
I'm researching lossless compression for a highschool mathematics
research essay and am fairly confused about how the linear prediction
coefficients are solved for within flac.
As far as I understand, Levinson Durbin Recursion is used to solve for
these coefficients, however, what I don't understand is what the
toeplitz matrix is composed of. I found sources using samples from
within

The Wikipedia page on this subject is not terrible:

The very high-level answer is that if want to choose your coefficients
to minimize the mean squared error of the prediction, then you get a
least-squares problem where the matrix you're inverting is just the
auto-correlation matrix of your signal (the Yule-Walker equations). The
discrete F...

I am not an expert on the guts of FLAC, but
there is some information about this at:
http://flac.sourceforge.net/documentation_format_overview.html
and scroll down to "MODELING".
