%% Read and Write Audio Files
% This example shows how to write data to an audio file, get information about the file, and then read data from the audio file.
%% Write to Audio File 1

load handel.mat

%
%% Write to Audio File 2

audiowrite('handel.wav',y,Fs)
clear y Fs

%
%% Get Information About Audio File

info = audioinfo('handel.wav')

%
%% Read Audio File

[y,Fs] = audioread('handel.wav');

%
%% Plot Audio 1

t = 0:seconds(1/Fs):seconds(info.Duration);
t = t(1:end-1);

%
%% Plot Audio 2

plot(t,y)
xlabel('Time')
ylabel('Audio Signal')
