Member Function Documentation

void Interpolator::initialize	(	unsigned int	_FIRLength,
		rateConversionRatio	_ratio,
		unsigned int	_sampleRate,
		bool	_polyphase = `true`
	)

inline

setup the sample rate interpolator

Parameters

_FIRLength	the interpolator's anti-aliasing filter length
_ratio	the conversion ratio (see rateConversionRatio)
_sampleRate	the actual sample rate
_polyphase	flag to enable polyphase decomposition

InterpolatorOutput Interpolator::interpolateAudio ( double xn )

inline

perform the interpolation; the multiple outputs are in an array in the return structure
