Hi, I am having trouble with this code. I want to do what the title says, but I don't know how to load only a single channel into my vector. Can someone help me, please?
the code:
% clear all the previous contents in workspace.
clc;
clear all;
% Read the audio file
[y, Fs] = audioread(‘Jolly Laugh.wav’ ; % read audio file to array
% Convert the stereo sound to the mono sound by loading only one channel
% data into the result vector
y = y(__________);
% play the audio
sound(y,Fs);
