The contribution of this paper is the parametric formulation ofa sparse representation for synthesizing a signal that has a timevaryingspherical directivity component.This class of signals can be considered conceptually asjoint angular-temporal impulse responses on the sphere. Usingadditive linearity we show how to synthesize these signals froma sparse discrete summation of elementary components that area linear combination of rotation and scattering operators on thesphere that have reflective and rotational resonant oscillations.The paper concludes with a discussion of applications ofthe method to acoustics and spatial auditory scene renderingtechnologies.
