...ce, i read that the stability of the interpolated LSF synthesis filter is satisfied only by preserving the intra-model interlacing theorem (the LSFs are interlaced with each other for a given LP analysis order) from speex codes, i see that stability of LSFs is enforced each time using the function lsp_enforce_margin. So, the synthesized filter after interpolation of filters may be unstable? will it be stable under certain conditions as mentioned in the previous paragraph? 2) bandwidth expansion lag windowing is applied to the autocorrelated signal and from what I understand, it's used for bandwidth ex...
