## S-MSVQ_Codec2.m
%---------------------------------------------------------------------------
% This script:
% * loads wave file with the speech corpus
% * extracts LPC coefficients for every 20 ms frame (with 10 ms overlap)
% * converts LPCs to LSFs and builds a training codebook: Nx10 matrix of floats
% * calculates coarse codebook plus additional fine codebooks for split MSVQ
% * dumps codebook data to a text file (codebooks.txt)
%
% In case of convergence error - re-run the script.
