However, there are many problems in using a surround sound system at home. Then, we propose the construction of a system that visualizes surround sound and makes it easy for general users to tune the localization of sound sources. In this report, we describe the direction estimation of instrumental sound sources as a necessary element for the visualization system. Focusing on the overtone structure of instrumental sounds, we show its effectiveness by simulation on a method that uses fundamental and harmonic components with relatively large amplitude.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-06-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19","bibliographicVolumeNumber":"2022-MUS-134"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":218411,"updated":"2025-01-19T15:10:13.876388+00:00","links":{},"created":"2025-01-19T01:18:46.904921+00:00"}
