Multiple pitch estimation is a popular problem in audio analysis. Particularly, the estimation from short signals has been desired in various real-time processing. The sinusoidal constraint differential equation (SCDE)-based method for realizing high-temporal resolution has been proposed for the frequency estimation of a single sinusoid or multiple sinusoids and fundamental frequency estimation. The SCDE-based method can efficiently and accurately estimate frequency even from a short-term signal. In this paper, as its extension towards the multiple pich estimation, we introduce the harmonic constraint to the SCDE-based method, and propose the method. Our experimental results show that our method estimated multiple pich with high accuracy with sinals of 2 ms.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"70","bibliographicVolumeNumber":"2024-SLP-151"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:33:28.037983+00:00","updated":"2025-01-19T10:24:50.691346+00:00","id":232540}
