Functions
void	calcDVFCoeffs (float alpha, float rho, float fs, float b, float a)
	Calculate the Distance Variation Function (DVF) filter coefficients, as described in [1].

void	interpDVFShelfParams (float theta, float rho, float iG0, float iGInf, float *iFc)
	Calculate the shelving filter parameters for the Distance Variation Function filter from the source (ipsilateral) azimuth and distance.

void	dvfShelfCoeffs (float g0, float gInf, float fc, float fs, float b0, float b1, float *a1)
	Calculate the DVF filter coefficients from shelving filter parameters.

void	calcDVFShelfParams (int i, float rho, float g0, float gInf, float *fc)
	Calculate the high shelf gains and cutoff parameters, given a azimuth index `i` and distance `rho`.

void	doaToIpsiInteraural (float azimuth, float elevation, float alphaLR, float betaLR)
	Convert a frontal azimuth/elevation to a modified Interaural-Polar coordinate.
