We extend the convolutional\nrecurrent neural network to handle more than one type of these multichannel\nfeatures by learning from each of them separately in the initial stages. We\nshow that instead of concatenating the features of each channel into a single\nfeature vector the network learns sound events in multichannel audio better\nwhen they are presented as separate layers of a volume. Using the proposed\nspatial features over monaural features on the same network gives an absolute\nF-score improvement of 6.1% on the publicly available TUT-SED 2016 dataset and\n2.7% on the TUT-SED 2009 dataset that is fifteen times larger.","url_abs":"http://arxiv.org/abs/1706.02291v1","url_pdf":"http://arxiv.org/pdf/1706.02291v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"sound-event-detection-using-spatial-features","repo_url":"https://github.com/sharathadavanne/sed-crnn","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"event-detection","task_name":"Event Detection"},{"task_slug":"sound-event-detection","task_name":"Sound Event Detection"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
