For binaural reproduction, in general, head-related transfer functions (HRTFs) are modeled as finite impulse response (FIR) models requiring a lot of parameters. The purpose of this study is to reduce the computational load of binaural processing through low-order modeling of the HRTFs. In this paper, an asymptotic method is used to identify the HRTFs in order to reduce the model orders. Experiments proved that the proposed method enables the HRTFs to be approximated with low-order models.
