N2 - A continuous function model is developed for efficient head-related impulse response (HRIR) representation. In this model, HRIR is modeled as the response of an IIR filter via common factor decomposition analysis, where HRIRs at the same azimuth but different elevations share the same IIR pole part and HRIRs at the same elevation but different azimuthes share the same IIR zero part. The pole and zero coefficients of the proposed common factor IIR (CF-IIR) filters are further modeled using sinusoidal functions of azimuth and elevation, respectively. A fast algorithm for evaluating sinusoidal function for efficient synthesis of virtual 3D sound is also developed.
