calculate all coefficients for several orders during cholesky factorization, the resulting coefficients are not strictly optimal though as there is a small difference in the autocorrelation matrixes which is ignored for the smaller orders Originally committed as revision 5758 to svn://svn.ffmpeg.org/ffmpeg/trunk

this will find the coefficients which minimize the sum of the squared errors, levinson-durbin recursion OTOH is only strictly correct if the autocorrelation matrix is a toeplitz matrix which it is only if the blocksize is infinite, this is also why applying a window (like the welch winodw we currently use) improves the lpc coefficients generated by levinson-durbin recursion ... optionally (use_lpc>2) support iterative linear least abs() solver using cholesky factorization with adjusted weights in each iteration compression gain for both is small, and multiple passes are of course dead slow Originally committed as revision 5747 to svn://svn.ffmpeg.org/ffmpeg/trunk
