There are many approaches in computing sound pitch. But, no approach was seen in developing enough response-time and accuracy of frequency discrimination for pitch discrimination training. Therefore new methodology is considered to improve response-time and accuracy of frequency discrimination. In FFT (Fast Fourier Transformation), there exist mathematical relations such that\\n(1) time_range_of_analysis^*frequency_discrimination = 1 and\\n(2) response_time = time_range_of_analysis/2^*computing_time,\\nwhich shows no improvement in both response-time and accuracy of frequency discrimination. Fortunately, there exist the fact such that many peaks of power spectrum : f[Hz], f^*2[Hz], f^*3[Hz], ･･････ as the results of FFT from a single f[Hz] pitch sound.\\nTo improve both response-time and accuracy of frequency discrimination, the following new method is considered in this paper. Step1 : Compute pitch roughly from f[Hz] power spectrum peak. Step2 : Compute pitch accurately from f^*n[Hz].","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"琉球大学","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/1374"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0386-5738","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN10144831","subitem_source_identifier_type":"NCID"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"琉球大学教育学部紀要 第一部・第二部","subitem_source_title_language":"ja"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1994-10-31","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"45","bibliographicPageEnd":"418","bibliographicPageStart":"411"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"Vol45p411.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2001473/files/Vol45p411.pdf"},"version_id":"d6bda301-a5bf-4607-95b8-6feeadc9d551"}]},"item_title":"即時応答型音程トレーナーの為の周波数解析手法について","item_type_id":"15","owner":"1","path":["1642837760806","1642838405037"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-08-08"},"publish_date":"2007-08-08","publish_status":"0","recid":"2001473","relation_version_is_last":true,"title":["即時応答型音程トレーナーの為の周波数解析手法について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T00:48:55.295212+00:00"}
