Nice.
But I've got some bad news... I was loading more wav files, and I have
found one file for which wavread fails to read it (your version and the
orginal one)... so you were right and more bug fixing must be done :O
I've uploaded the file to:
http://www.telefonica.net/web2/mrvinyes/fails.wav.zip

Maybe sbdy can find some time to fix it. I'll try it later; too busy now...
I think we should take a look at the source of programs like rezound,
which support perfectly all kind of wav's, and the port it to matlab...
