Modal expansion of HRTFs: Continuous representation in frequency-range-angle

Zhang, Wen; Abhayapala, Thushara; Kennedy, Rodney; Duraiswami, Ramani


This paper proposes a continuous HRTF representation in both 3D spatial and frequency domains. The method is based on the acoustic reciprocity principle and a modal expansion of the wave equation solution to represent the HRTF variations with different variables in separate basis functions. The derived spatial basis modes can achieve HRTF near-field and far-field representation in one formulation. The HRTF frequency components are expanded using Fourier Spherical Bessel series for compact...[Show more]
