Documentation

Produce the full set of linear prediction coefficients from a frame of speech waveform.

Parameters:

sig - : the frame of input waveform
acf - : the autocorrelation coefficients
ref - : the reflection coefficients
lpc - : the LPC coefficients The order of the lpc analysis is given as the size of the <parameter> lpc <parameter> vector - 1. The coefficients are placed in the locations 1 - size, and the energy is placed in location 0.
