A channel in audio refers to a separate stream of audio data. The most common values are:
- 1 channel: Mono
- 2 channels: Stereo
For example, if you read a stereo WAV file as given below, you will see that ‘y’ will be a N-by-2 matrix where the first column is the left channel and the second column is the right channel:
[y, fs] = audioread(‘filename.wav');
size(y)
For more information on the ‘audioread’ function, refer to the given MATLAB Documentation:
