Reading .wav file in Matlab Coder

I want to read an audio file with matlab coder. The problem is that wavread() is not supported, but as this is a pretty essential part of any audio coding I am thinking that there must be another way to achieve this? Any ideas?

fopen() is now supported starting from Matlab 2013a. See here.

What is your use case? If you really just want to run the generated code in a MEX-function within MATLAB you can use coder.extrinsic to call wavread. This will not work outside of the MATLAB environment.

Outside the MATLAB environment, you will need to use custom C code integration.

The WAV file format is fairly simple & widely documented for example here. You can use the low-level file IO functions, fopen(), fread(), fseek to read the file, assuming these are themselves available. This is exactly what wavread() does internally - take a look at the source.
