Sound files with 4 channels in MATLAB

Dear,

When I try to read the handel.wav audio in MATLAB, I found that it is a mono (1 channel) sound (p=1).

Can you suggest please an audio with 4 channels. It means Its not mono or stereo. I have to fing p=4

[Rik]

What do you need it for? And why can't you just replicate the mono sound to four channels?

@Rik How can I replicate it in MATLAB please

Perhaps this —

v1 = rand(5,1)

v1 = 5×1

0.0323 0.5666 0.5766 0.9202 0.0240

v4 = v1 * ones(1,4)

v4 = 5×4

0.0323 0.0323 0.0323 0.0323 0.5666 0.5666 0.5666 0.5666 0.5766 0.5766 0.5766 0.5766 0.9202 0.9202 0.9202 0.9202 0.0240 0.0240 0.0240 0.0240

S = load('handel');
new_y = repmat(S.y,1,4);
size(new_y)

ans = 1×2

73113 4

Now you can no longer use the sound function, as that only supports mono and stereo.
