Previous studies have reported the effects of appropriate cut frequencies on viewer impressions, as well as the impact of synchronizing visual and auditory information on cognition and sensitivity. These findings suggest that incorporating visual expressions, along with corresponding auditory expressions, could further enhance the viewer's experience. In this study, we propose a method to improve the music experience of live video viewing by automatically adding visual and auditory expressions. We conducted a subjective evaluation through questionnaires, comparing levels of immersion, social presence, and interest in the performers to assess the effectiveness of the proposed method. The results demonstrated that incorporating visual expressions was effective across all evaluation criteria. Additionally, when viewers had a high level of satisfaction with single-viewpoint live videos, combining visual and auditory expressions further enhanced their music experience.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1724","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1715","bibliographicIssueDates":{"bibliographicIssueDate":"2025-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"66"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/0002006327","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"80578"},"created":"2025-12-09T01:41:28.856997+00:00","updated":"2025-12-19T07:31:38.640421+00:00"}
