[Poster Presentation] A study of processing time reduction for sound source localization by sub-band peak hold phase processing
Yuki Imanishi, Yutaka Kaneda (Tokyo Denki Univ.) EA2015-47
Abstract (in Japanese) (See Japanese page) 
(in English) Sound source localization is applied to various technologies such as directional sound receiving and robot audition. In a real environment, however, a localization error occurs owing to reflected sounds. To reduce the localization error, we previously proposed sub-band peak hold (SBPH) processing and sub-band peak hold phase (SBPHP) processing. These processing methods work well but require a large processing time, making them unsuitable for real-time processing. In this paper, we propose a method of reducing the time required for SBPHP processing. In this method, we reduce the window shift length for sub-band processing while maintaining the localization performance. Experimental results show that the processing time of the proposed method is about 25% shorter than that for the conventional method.
