Can anyone help please? I am trying to use wavread to convert .wav to .matfiles but I am getting a message saying "undefined function or variable 'wavread'.

For example one of my named sound files: y = wavread('barber-s-01-t1.wav')

Or is there another way of converting to .mat files?

Any suggestions would be much appreciated.

Thanks in advance.

The wavread function was deprecated a while ago. Use the audioread function (R2012b and later versions) instead.

Thank you.

So I typed this: [y,Fs] = audioread('barber-s-01-t1.wav') which seemed to work.

Then how do i actually convert or save it to a .mat file?

Sorry if I seem completely cluless (because I am!). I am trying to get some understanding of Matlab!

My pleasure.

Create a name for the output file (I call it ‘soundfile.mat’ here), then save ’y’ and ‘Fs’ to your .mat file:

save('soundfile.mat', 'y', 'Fs')

You need to save ‘Fs’ (and any metadata as well) to it. In your workspace, ‘y’ will exist as a one- or two-column double array, and ‘Fs’ as a scalar.

Also, when you read it, load it into a variable to create a structure. You can then rename any parts of it to whatever variable names you want, not necessarily the variable names that exist in the .mat file. See: Load List of Variables into Structure Array
