int g722_decode	(	g722_decode_state_t *	s,
		int16_t	amp[],
		const uint8_t	g722_data[],
		int	len
	)

Decode a buffer of G.722 data to linear PCM.

Parameters:

	s	The G.722 context.
	amp	The audio sample buffer.
	g722_data
	len

Returns:

The number of samples returned.

g722_decode_state_t* g722_decode_init	(	g722_decode_state_t *	s,
		int	rate,
