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_1522300295150": "ja", "subitem_1522300316516": "琉球大学"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "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_1522646500366": "ISSN", "subitem_1522646572813": "0386-5738"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN10144831"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学教育学部紀要 第一部・第二部"}]}, "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_1522305645492": "NA", "subitem_1600292170262": "http://purl.org/coar/version/c_be7fb7dd8ff6fe43"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "Vol45p411.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "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"], "permalink_uri": "http://hdl.handle.net/20.500.12000/1374", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-08-08"}, "publish_date": "2007-08-08", "publish_status": "0", "recid": "2001473", "relation": {}, "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_shared_id": -1}
