% Non Scalable TWIN-VQ program implementation in MATLAB.
%-------------------------------------------------------
% This program encodes monoaural audio .wav files using the TWIN-VQ
% algorithm. The program assumes that the input .wav file is single channel
% audio sampled at 44100 samples per second and with 16 bits per sample.
% However, the program can be modified to work with different sampling 
% rates. The program can encode and decode in the range of 6 - 64 kbps.
%
% The main encoding program is encode_tvq.m.
% Function call: encode_tvq(<wave file>, bitrate)
% Example: encode_tvq('..\original_audio\bene.wav',8000);
%
% Note that the bitrate is always in bits per sample and not kilo bits per 
% sample.
%
% The program encodes the audio at the appropriate bitrate and stores the 
% indices and side information as a .MAT file.
%
% The main decoding program is decode_tvq.m
% Function call: decode_tvq
%
% This program opens the appropriate .MAT file and reconstructs the audio 
% from it. Before reconstructing the audio sequence the program prompts the
% user to input the reconstruction bitrate in the range between the 6 kbps
% and the maximum encoded bitrate.
