clc, clear
% load data
load handel.mat
filename = 'handel.wav';
audiowrite(filename, y, Fs);
% save only 2 second of audio
y = y(1:2*Fs);
% extend the audio from 2 sec to 2 minutes
rep = round(2*60/2);
yrep = repmat(y, [rep, 1]);
% write the extended audio
audiowrite(filename, yrep, Fs);
% read the extended audio
[y, Fs] = audioread('handel.wav');
% listen to extended audio
sound(y, Fs);
