static void aw_parse_coords	(	WMAVoiceContext *	s,
		GetBitContext *	gb,
		const int *	pitch
	)			[static]

static void aw_pulse_set1	(	WMAVoiceContext *	s,
		GetBitContext *	gb,
		int	block_idx,
		AMRFixed *	fcb
	)			[static]

Apply first set of pitch-adaptive window pulses.

Parameters:

	s	WMA Voice decoding context private data
	gb	bit I/O context
	block_idx	block index in frame [0, 1]
