Hello, I need help. I was record on my phone a sound. I want to hear that sound in matlab. How to do that?
I already tried with load and audioread and so on. Than I tried that sound convert in .wav and he still does not recognize that file. When I put for example load pcela.wav % pcela.wav is my name of that recorded sound Error using load Unknown text on line number 1 of ASCII file pcela.wav "RIFF’_".
Am I doing something wrong? Please help me I don't have no idea anymore and I cant find anything similar on web.
Thanks.

I found a matlab script (with exe and library) that can import m4a files. I tried it and it seems to work. See www.ee.columbia.edu.
