lpc varying L

This exercise shows the matching behavior of the LPC polynomial log magnitude spectrum of the STFT.

This MATLAB exercise illustrates the matching behavior of the LPC polynomial log magnitude spectrum to the log magnitude spectrum of the STFT of the designated input frame of speech as a function of the frame size, Lm for a range of values of Lm; (e.g., Lm =Linit, Linit+Ldelta, ... , Linit+4*Ldelta) msec. This exercise processes a frame of a speech file (from a designated starting sample and a varying frame duration), and plots the LPC polynomial log magnitude spectrum as a function of the speech frame duration, Lm, for each of 5 frame durations, and compares the results with the log magnitude spectrum of the STFT of the designated frame of speech.
