OSX / iOS: Reading a .WAV into a float buffer

Question

I've got a ~1s mono .WAV on disk. I would like my OSX (and later iOS) app to read it into a float buffer.

What's the simplest way to achieve this?

Answer 1

Solution is to use ExtAudioFile()

I found it reading the most excellent Core-Audio bible

Answer 2

The libsndfile way :)

   SF_INFO sfinfo;
   SNDFILE *sf;
   float *buf;
   int err_code;

   sfinfo.format = 0;
   sf = sf_open("/meow.wav", SFM_READ, &sfinfo);
   err_code = sf_error(sf);
   if (err_code == SF_ERR_NO_ERROR) {
      buf = malloc(sfinfo.frames * sfinfo.channels * sizeof(float));
      sf_read(sf, buf, sfinfo.frames * sfinfo.channels);
      printf("Done!\n");
   } else {
      printf("%s\n", sf_error_number(err_code));
   }
