Function Documentation

const void* pcm_convert	(	struct pcm_convert_state *	state,
		const struct audio_format *	src_format,
		const void *	src,
		size_t	src_size,
		const struct audio_format *	dest_format,
		size_t *	dest_size_r
	)

Converts PCM data between two audio formats.

Parameters:

	state	an initialized pcm_convert_state object
	src_format	the source audio format
	src	the source PCM buffer
	src_size	the size of src in bytes
	dest_format	the requested destination audio format
	dest_size_r	returns the number of bytes of the destination buffer

Returns:

the destination buffer
