Abstract (in Japanese) (See Japanese page) 
(in English) As a sound source localization method using two microphones, GRODMIC(GRODup Delay between MICrophones)has been developed. GRODMIC estimates the time differences of arrival between microphones based on the group delay characteristics of a propagation delay characteristics identified by a digital filter. In this process, because ripples make occur in the group delay characteristics due to estimation residuals and other reasons, and thus the estimation performance is often degraded. it is apparent that the extraction of flat group delay samples is an effective solution to this problem. Therefore, it is effective to extract high density flat group delay samples. In this study, the estimation performance improvement usinghigh density flat group delay samples is proposed.
