This enables the service to trace the channel of a broadcast program that a user is watching or listening to. One approach is to record an audio signal from the user's mobile device, and match it with one in a reference database. However, reverberation and exogenous noise distort a recorded audio signal, making accurate identification more difficult. This paper presents a new fingerprinting method for content identification that is robust against reverberation and noise. It employs pseudo-sinusoidal components, which are components that can be regarded as sinusoidal over a short period of time. The method generates a fingerprint that represents the distribution of pseudo-sinusoidal components in the time-frequency domain. Experimental results show that the method can match a 5-s-long input signal against 792 hours of reference signals in 1.56 s on a single PC, and can identify the correct program with a recall of over 92% and a precision of 100% in a realistic setting.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-05-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2013-MUS-99"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:40:57.902043+00:00","updated":"2025-01-21T15:15:24.706622+00:00","id":91808}
