Reading .wav file in Matlab Coder

问题:

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?

回答1:

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.

回答2:

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.

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