MATLAB: How do you apply amplitude modulation to a wav file

amplitude modulationwav

I would like to apply AM to a wav file, but I'm not sure how to go about it

Hi,

1st you would need to read the wav file with: [YY, fs] = audioread('MY_wav.wav');

then perform the AM operations with yx = ammod(YY, Fc, Fs). How to do it shown here.

Good luck.

Doc audioread..

[y,fs] = audioread(filename);
    dt = 1/fs;
    t = 0:dt:(length(y)*dt)-dt;
    plot(t,y); 
     xlabel('Seconds'); 
     ylabel ('Amplitude');

That is the correct result. See Product-to-sum and sum-to-product identities (link) for the maths underlying it.
