def SDL_LoadWAV_RW(src, freesrc):
"""Load a WAVE from the data source.
The source is automatically freed if `freesrc` is non-zero. For
example, to load a WAVE file, you could do::
SDL_LoadWAV_RW(SDL_RWFromFile('sample.wav', 'rb'), 1)
You need to free the returned buffer with `SDL_FreeWAV` when you
are done with it.
:Parameters:
- `src`: `SDL_RWops`
- `freesrc`: int
:rtype: (`SDL_AudioSpec`, `SDL_array`)
:return: a tuple (`spec`, `audio_buf`) where `spec` describes the data
format and `audio_buf` is the buffer containing audio data.
