AB  - Binaural technology using a dummy-head is a powerful technique to provide realistic sound reproduction through headphones. To obtain the binaural signals as if a listener moves around in the sound field, we need to move the dummy head. To overcome this problem, it is a promising approach to convert signals observed by a microphone array into binaural signals at arbitrary positions. In this paper we aim to reproduce horizontal binaural signals at semi-arbitrary listener’s positions using linear microphone array signals based on the inverse wave propagation method with spatial over sampling and simulated head-related transfer function (HRTF) directivity pattern. We perform the computer simulation and listening experiments in a reverberant room. A listening test is performed for two cases to verify the performance of the sound localization (case-I) and distance perception (case-II). We con?rm that the binaural signals obtained by the proposed method are almost expressed by the HRTF directivity pattern. We find that the angle errors of sound localization is ranged from 1.2° to 4.2° from the results of case-I. According to the results of case-II, the subjects can perceive a distance change of the virtual sound image when the auditory stimulus is white noise
