decode_audio_file_into_dynamic_memory()

std::tuple< void *, ALsizei > decode_audio_file_into_dynamic_memory	(	const char *	filename,
		SNDFILE *	sound_file,
		SF_INFO	sound_file_info,
		enum FormatType	sample_format,
		ALenum	format,
		ALint	byteblockalign,
		ALint	splblockalign )

Decode the whole audio file to a buffer

Returns

the pointer to dynamic memory, along with the number of bytes it takes up

determine_format_type()

		SNDFILE *	sound_file,
		SF_INFO	sound_file_info,
		ALsizei	num_bytes,
		ALenum	format,
		ALint	splblockalign )

Buffer the audio data into a new buffer object, then free the data and close the file.

Returns

the identifier to the openal buffer
