Linear predictive analysis of a speech signal. This program takes as input a signal and outputs a LPC, PARCOR or LAR SPro data file. For each frame of the input signal, a generalized LPC analysis is performed using the Levinson-Robinson-Durbin procedure to solve the Yule-Walker equations (implemented as in [5]). Option -order=n controls the order of the LPC analysis. The default behavior is to output the linear prediction coefficients but option -parcor (resp. -lar) enables to save reflexion (resp. log-area ratio) coefficients to the output file.
