Is it possible if we convert the audio that has 1 channel (mono) to 2 channel (stereo) in Matlab?

Hello

I have 2 channel binaural audio

I re-recorded using my cellphone and the audio was saved into one channel

Is it possible if we convert the audio that has 1 channel (mono) to 2 channel (stereo) in Matlab?

if possible, what kind of Matlab code to use ?

Thank you

Stereo = repmat(Mono(:), 1, 2);

In the case where Mono is already known to be a column vector then this can be simplified to

Stereo = Mono(:, [1 1]);

However, you will not be able to separate channels back to their original -- not unless there is some distinguishing characteristic of the two. For example if the original two channels were sine tones of different frequencies, then Yes, you might be able to separate them out. Two singers that are not harmonizing, and which have distinct voices... might be doable with some work. Left and right click tracks at irregular times... NO.

okay Mr, thank you

It works

what if the case is different Mr

I have binaural audio with two channels

then the audio is divided into two which are one channel each

Using this code Mr :

mono=y(:,1);

Then after the process, I want to combine the two audios into one audio that has two channels as before

although the audio of this result is not the same as the beginning

So, how to combine them Mr ?

Thank you

new_stereo = [new_mono1, new_mono2];
