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

Perhaps this —

v1 = rand(5,1)
v1 = 5×1
0323
5666
5766
9202
0240
v4 = v1 * ones(1,4)
v4 = 5×4
0323    0.0323    0.0323    0.0323
5666    0.5666    0.5666    0.5666
5766    0.5766    0.5766    0.5766
9202    0.9202    0.9202    0.9202
0240    0.0240    0.0240    0.0240

在 MATLAB Online 中打开

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.
