AB  - This paper addresses efficient interpolation of Head-Related Transfer Functions (HRTFs) for binaural generation of moving sound. Aiming at computational complexity reduction, the authors recently proposed a new method for HRTF interpolation based on auxiliary Inter-positional Transfer Functions (IPTFs). The present paper reviews this IPTF-based method and focuses on IPTF design, which employs tools such as balanced model reduction and spectral smoothing to compute a complete set of reduced-order IPTFs. The interpolation scheme based on these reduced-order IPTFs is computationally more efficient and yields results perceptively comparable to those attainable by the bilinear method, which uses the HRTFs directly. Therefore, the proposed method is promising for real-time generation of spatial sound.
