Reliable pitch extraction methods for monophonic signals exist, but polyphonic cases are much more difficult, especially if the number of the sound sources is not known. In this report, a sequential estimation method for the number of the sound sources is proposed. Using the peak detection in the time-domain and the exponentially decaying power model, the generation and the continuity of each sound source is checked. The effectiveness is evaluated by applying to real sound data.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岩野, 公保","creatorNameLang":"ja"},{"creatorName":"イワノ, キミヤス","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"14586","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"横道, 政裕"},{"creatorName":"ヨコミチ, マサヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"Yokomichi, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6617","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30274773","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30274773"}]},{"creatorNames":[{"creatorName":"Iwano, Kimiyasu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14588","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"43engineering40_pp.251-256.pdf","filesize":[{"value":"892.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"43engineering40_pp.251-256.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/2779.1/files/43engineering40_pp.251-256.pdf"},"version_id":"ffc8f2c6-a267-470b-b82a-3e610ba5bf0c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Automatic Music Transcription System, Sound source estimation, Multi-pitch extraction, Power decay model","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"基本周波数帯域におけるパワー減衰モデルを用いた音源数推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"基本周波数帯域におけるパワー減衰モデルを用いた音源数推定","subitem_title_language":"ja"},{"subitem_title":"Estimation of number of sound sources in multi-pitch extraction by power decay model in fundamental frequency","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["36","73","321"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-03-12"},"publish_date":"2012-03-12","publish_status":"0","recid":"2779.1","relation_version_is_last":true,"title":["基本周波数帯域におけるパワー減衰モデルを用いた音源数推定"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-07-29T11:22:11.055013+00:00"}
