how can i play sound to the right stereo channel only?

The sound command sends sound to both earphones. how do I send a sound to just one?

Answer 1

[Star Strider]

The sound files are (usually) a (2xN) or (Nx2) matrix, one row or column for each channel. To have it play in only the right channel, set the other to a vector of zeros:

Fs = 44100;
t = linspace(0, Fs*2, Fs*2);
s = sin(2*pi*t*1000);
Out = [zeros(size(t)); s]';

sound(Out, Fs)

There is a problem with the sound on my laptop, so it’s not rendering this correctly. It should work on your computer.

By convention, the left channel is the first column and the right channel is the second column.

With sound it is ok but if we audiowrite it is not work

Alireza Naghsh is right: Play works stereo, but when writing to file it doesn't seem to work.
