compute_allocation()

int compute_allocation	(	const CELTMode *	m,
		int	start,
		int	end,
		const int *	offsets,
		const int *	cap,
		int	alloc_trim,
		int *	intensity,
		int *	dual_stero,

		int *	fine_priority,
		int	C,
		int	LM,
		ec_ctx *	ec,
		int	encode,
		int	prev,
		int	signalBandwidth
	)

Compute the pulse allocation, i.e. how many pulses will go in each band.

Parameters

m	mode
offsets	Requested increase or decrease in the number of bits for each band
total	Number of bands
pulses	Number of pulses per band (returned)

Returns

Total number of bits allocated

compute_pulse_cache()
