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: https://en.wikipedia.org/wiki/Linear_prediction 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 discret...
