MATLAB: How to audiowrite a soundfile from m4a to wav

Question

Hello!

I want to write an audiofile from m4a to wav? I thought it was easy, but I miss something I guess..

This is what I'm doing:

load hoi.m4a
filename='hoi.wav'
audiowrite(filename, y, Fs)

This is what the help function says, but what am I supposed to fill in on y and Fs?

Thanks!

Laura - I think that you want to use audioread first as

 m4AFilename = 'hoi.m4a';
 [y,Fs] = audioread(m4AFilename);

and then write it as a wav file using audiowrite as

 wavFilename = 'hoi.wav';
 audio write(wavFilename,y,Fs);

Try the above and see what happens!
