Our method is also aiming at retrieving similar music such as that played at different tempo, played with different instruments, and so on. In this paper, we evaluate the robustness of our method against these changes. Experiments using a test database containing 216 music pieces show that the search accuracy is quite good. For example, when the average length of the queries is 19 s, the detection rate is more than 90% even when the tempo or pitch differs. It is also shown that the detection rate is about 77% even when the instruments were changed.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"44","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"39","bibliographicIssueDates":{"bibliographicIssueDate":"2004-12-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"127(2004-MUS-058)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T05:12:58.131738+00:00","created":"2025-01-18T23:19:28.441274+00:00","links":{},"id":55941}
