Estimating the deviations is required for score-guided 1 instrumental part removal or any other manipulation of musical audio signal. For this problem, existing alignment algorithms are not sufficient because they deal with only tempo. On the other hand, our approach models how musical signal is generated from score, considering (i) tempo variation, (ii) deviations in each note and (iii) variation of acoustic signal features, and then, estimates tempo and deviations with max imum a posteriori probability based on the model. Simulation quantitably show our approach has advantage of processing deviation and needs more consideration especially on deviation modeling.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"110","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"105","bibliographicIssueDates":{"bibliographicIssueDate":"2007-08-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"81(2007-MUS-071)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":55777,"updated":"2025-01-22T05:17:38.107636+00:00","links":{},"created":"2025-01-18T23:19:20.783165+00:00"}
