MATLAB: How is audio data stored in matlab

audioMATLAB

is it stored in simple arrays or multidimensional arrays?

[y,Fs] = audioread('YourAudioFile');
%Y is a nx1 or nx2 array
% Fs is a sample rate

To get the info of your audio file you can use

audioinfo('YourAudioFile')

You can use audioread function

[y,fs]=audioread('yourfile.mp3')

To play your file

sound(y,fs)

Look at

doc audioread

Difficult to say. You might not have a speaker or sound card connected, or its volume might not be up high enough or it might be muted.

Or perhaps you should be using

[y,fs] = waveread('filename');
sound(y,fs);
