The peaks of the LP spectrum represent the resonances and harmonics. One of the peaks corresponds to the pitch. Estimating the peak locations from a discrete spectrum may compromise resolution, as the number of bins limits the spectral resolution. LP spectrum is an all-pole model where poles model the spectral peaks. LP offers the advantage of computing precise pitch and harmonic values directly from the pole angles of the denominator polynomial (⁠ 1,aks⁠) of Eq. (2).
