Abstract

This paper proposes a method of estimating the HRTF (head-related transfer function) to shorten its measurement time by applying a system identification method. Since each directional HRTF has conventionally had to be measured one by one, a larger number of directions results in a longer HRTF measurement time. Since multidirectional HRTFs can also be treated as an MISO (multiple-input single-output) system, the proposed method estimates them simultaneously by a PEM (prediction error method). Experimental results indicated that the proposed method shortens the measurement time for HRTFs of 61 directions by a factor of 280.
