MATLAB: Cannot create mat file.

Question

>> filename=('s2.wav');
>> y=wavread(filename);
>> [y,Fs,nbits]=wavread(filename);
>> save(filename,'-mat');

why save(filename,'-mat'); does not create the *.mat file?

Answer 1

You should do this:

filename = 's2.wav';
[y, Fs] = audioread(filename);
save('s2.mat','y');
