Use wavread to read the file into MATLAB. Then, use save to save the file as a .mat file.

See the help for wavread and save

[fatimah]

in the command line of the matlab first i was wrote wavread signal.wav

then the command line give me the value of this wave

then i was wrote save ans next i have ans.mat

put when I load it in the wavemenu make me error message.

What error did you get? and how did you save the .wav file, did you save the whole workspace by mistake

Try this:

[sig,fs] = wavread(filename);

save('testsig.mat','sig');

[fatimah]

Thanks

I tray

[sig,fs] = wavread(filename);

save('testsig.mat','sig');

and I get testing.mat

put I need to generated my matlab code from wavemenu -> multiple 1-D ->multivariate Denoising

put I can't do that "I don't have the choice in the file menu"

How I can do that can you help me :\

and thank you for every thing :)

[Wayne King]

but wait, the output from one .wav file should not be a multivariate signal

[fatimah]

my wave file is content mixed signal ..

can you help me to generate my denoising code

[Wayne King]

So it's just a Nx1 vector. Then just use wavelet 1-D. All noisy signals are "content-mixed signals". By the way, on any wavemenu subitem, you can always use Import from Workspace, you don't have to save the data as a .mat file.
