I have an audio signal ( of my voice ) .However,I want to multiply it by cosine function.
t=[1:1000];
n=cos(2*pi*fc*t);
[y fs]=audioread('message.wav');
How can I do that ?

The cosine signal must be the same size as ‘y’.
One way to define it as such:
t = linspace(0, 1, fs);
Then create the cosine funciton to be what you want.
Try this:
t = linspace(0, 1, fs);
fc = 440;
n=cos(2*pi*fc*t).';
y_new = y .* n;
sound(y_new,Fs)
