This function loads a WAVE <TT

>If this function succeeds, it returns the given
<A

filled with the audio data format of the wave data, and sets
<TT

CLASS="FUNCTION"
>malloc</TT

buffer containing the audio data, and sets <TT
CLASS="PARAMETER"
><I
>audio_len</I
></TT

to the length of that audio buffer, in bytes.  You need to free the audio
buffer with <A

> when you are
done with it.</P
><P
>This function returns <TT

error message if the wave file cannot be opened, uses an unknown data format,
or is corrupt.  Currently raw, MS-ADPCM and IMA-ADPCM WAVE files are supported.</P
