Approximation of binaural room impulse responses

Abstract

An approach to approximation of Binaural Room Impulse Responses (BRIRs) is presented. Here, a BRIR is considered to have two constituent parts: the anechoic Head Related Impulse Response (HRIR), convolved with the Room Impulse Response (RIR). Each part is approximated individually. The HRIR is partitioned as the convolution of a directional independent component and a directional dependent subsystem. The RIRs are split into their early and late reection components, and an interpolation method is presented using Dynamic Time Warping (DTW).
