The system compares the pitch and frequency spectrum of the sound played by the user with that of a reference sound source, and provides feedback and advice on how to improve based on the difference. Previous wind instrument learning support systems used methods such as attaching sensors to the instrument itself or placing markers around the mouth and measuring them with a camera, but these methods had the problem of altering the normal playing sensation and tone quality of the performer. This research solved this problem by performing a Fourier transform on the sound output from a normal instrument without any sensors attached, and estimating the embouchure state from the detected harmonic condition, thus enabling more practical practice and advice.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告エンタテインメントコンピューティング（EC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-03-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2024-EC-71"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":233642,"links":{}}
