After listening to some CDs, I found some of those were treated in an excessive way for increasing the loudness. As a result of excessive treatment, despite the successful increased loudness, I have come to doubt that there is deterioration in sound quality or a change in balance among musical instruments. Therefore, I verified the situation, and I described below my consideration to what could be the right recording level of CDs. With regard to DVD-Videos, most of them were movie-films when they were initially put on the market, but nowadays many musical DVD titles recording the live concerts or the promotional films have also been released. I sometimes found a significant difference in the recorded audio level between a CD and a DVD-Video, which were packaged together in a set article. It is inconvenient for users to adjust volume level every time they listen to it when there is a variation in the Audio Level within the same article, and the existence itself of a variation in loudness within the same media is a problem. Therefore, I describe below my verification of the situation, the causes, and the countermeasures for them.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"2","subitem_description_type":"Other"}]},"item_3_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00004920326","subitem_description_type":"Other"}]},"item_3_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_3_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_publisher_22":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"尚美学園大学芸術情報学部","subitem_publisher_language":"ja"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11624171","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13471023","subitem_source_identifier_type":"PISSN"}]},"item_3_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"尚美学園大学芸術情報学部情報表現学科"}]},"item_3_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Shobi University"}]},"item_3_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"ディジタル パッケージ メディア ニ オケル オンセイ シュウロク レベル ニ カンスル コウサツ : サイセイ スル タチバ カラ ミタ テキセツナ オンセイ レベル ハ イカニ アルベキカ","subitem_title_language":"ja-Kana"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"千葉, 精一","creatorNameLang":"ja"},{"creatorName":"チバ, セイイチ","creatorNameLang":"ja-Kana"},{"creatorName":"CHIBA, Seiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-21"}],"displaytype":"detail","filename":"KJ00004920326.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"KJ00004920326.pdf","url":"https://shobi-u.repo.nii.ac.jp/record/267/files/KJ00004920326.pdf"},"version_id":"920f7ea7-1373-480e-ae61-1f12ed1379e6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"音量感(ラウドネス)","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"CDマスタリング・レベル","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"DVD-Videoのオーディオレベル","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ダイナミックレンジ圧縮","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"オペレイティング・レベル","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ラウドネスレベルメータ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Loudness","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CD-Mastering level","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Audio Level for DVD-Video","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dynamic-range Compression","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Operating Level","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Loudness Level Meter","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":"ディジタル・パッケージ・メディアにおける音声収録レベルに関する考察 : 再生する立場から見た適切な音声レベルは如何にあるべきか","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ディジタル・パッケージ・メディアにおける音声収録レベルに関する考察 : 再生する立場から見た適切な音声レベルは如何にあるべきか","subitem_title_language":"ja"},{"subitem_title":"A study on the audio recording level of the Digital Package Media : What audio-level could be the best for users in terms of reproduction","subitem_title_language":"en"}]},"item_type_id":"3","owner":"3","path":["46"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-04-21"},"publish_date":"2017-04-21","publish_status":"0","recid":"267","relation_version_is_last":true,"title":["ディジタル・パッケージ・メディアにおける音声収録レベルに関する考察 : 再生する立場から見た適切な音声レベルは如何にあるべきか"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-21T02:42:55.877805+00:00"}
