Function Documentation

int sms_residual	(	int	sizeWindow,
		sfloat *	pSynthesis,
		sfloat *	pOriginal,
		sfloat *	pResidual,
		sfloat *	pWindow
	)

get the residual waveform

Parameters:

	sizeWindow	size of buffers
	pSynthesis	pointer to deterministic component
	pOriginal	pointer to original waveform
	pResidual	pointer to output residual waveform
	pWindow	pointer to windowing array

Returns:

residual percentage (0 if residual was not large enough)

Todo:

why is residual energy percentage computed this way? should be optional and in a seperate function
