However, creating a new large dataset requires recording many samples for many performance techniques, which is costly and time-consuming. Therefore, in this study, we attempt to augment data by increasing the number of recording microphones without increasing the recording duration and verify the effectiveness of this data augmentation method. As a result of recording \ufb02ute playing techniques using multiple microphones, the accuracy and macro F1-Score of a convolutional neural network-based classi\ufb01er improved when using a combination of the \ufb01ve most close-to-source microphones. The classi\ufb01er\u2019s performance further improved when data were combined with a data augmentation method based on pitch shifting.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Paper written by Nicolas Brochec*, Tsubasa Tanaka*, and Will Howie*\u2020 has been presented at the ICMC2024 (International Computer Music Conference 2024). * Tokyo University of the Arts\u2020 Japan Society for the Promotion of Science Full publication Abstract: Within existing research on the automatic classi\ufb01cation of musical instrument playing techniques, few available datasets include enough playing [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[46],"tags":[],"class_list":["post-2136","post","type-post","status-publish","format-standard","hentry","category-publications-research"],"aioseo_notices":[],"blog_post_layout_featured_media_urls":{"thumbnail":"","full":""},"categories_names":{"46":{"name":"Publications","link":"https:\/\/reach.ircam.fr\/index.php\/category\/research\/publications-research\/"}},"tags_names":[],"comments_number":"0","wpmagazine_modules_lite_featured_media_urls":{"thumbnail":"","cvmm-medium":"","cvmm-medium-plus":"","cvmm-portrait":"","cvmm-medium-square":"","cvmm-large":"","cvmm-small":"","full":""},"_links":{"self":[{"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/posts\/2136","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/comments?post=2136"}],"version-history":[{"count":3,"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/posts\/2136\/revisions"}],"predecessor-version":[{"id":2140,"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/posts\/2136\/revisions\/2140"}],"wp:attachment":[{"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/media?parent=2136"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/categories?post=2136"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/reach.ircam.fr\/index.php\/wp-json\/wp\/v2\/tags?post=2136"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
