The term \u201caudio\u201d is used here to distinguish from generative \u201cmusic\u201d systems, emphasizing the strong coupling between processes governing the production of high-level music and lower-level audio. The classical time-invariant implementation of an all-pass filter is subject to issues of instability that can arise when time-invariant filter parameters are allowed to vary over time. These instabilities are examined, along with the adoption of a power-preserving rotation matrix formulation of the all-pass filter to ensure stability and ultimately an improved synthesis for a generative audio system. <\/jats:p>","DOI":"10.1162\/comj_a_00344","type":"journal-article","created":{"date-parts":[[2016,4,5]],"date-time":"2016-04-05T16:57:10Z","timestamp":1459875430000},"page":"54-69","source":"Crossref","is-referenced-by-count":2,"title":["Generative Audio Systems Using Power-Preserving All-Pass Filters"],"prefix":"10.1162","volume":"40","author":[{"given":"Greg","family":"Surges","sequence":"first","affiliation":[{"name":"Department of Music University of California, San Diego 9500 Gilman Drive La Jolla, CA 92093 USA"}]},{"given":"Tamara","family":"Smyth","sequence":"additional","affiliation":[{"name":"Department of Music University of California, San Diego 9500 Gilman Drive La Jolla, CA 92093 USA"}]},{"given":"Miller","family":"Puckette","sequence":"additional","affiliation":[{"name":"Department of Music University of California, San Diego 9500 Gilman Drive La Jolla, CA 92093 USA"}]}],"member":"281","reference":[{"key":"p_1","first-page":"1076","author":"Abel J.","year":"2006","journal-title":"Proceedings of the Audio Engineering Society 121st Convention"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2005.845602"},{"key":"p_5","first-page":"305","author":"Kleimola J.","year":"2009","journal-title":"Proceedings of the International Conference on Digital Audio Effects"},{"key":"p_6","first-page":"28","author":"Lazzarini V.","year":"2009","journal-title":"Proceedings of the International Conference on Digital Audio Effects"},{"key":"p_8","first-page":"445","author":"Puckette M.","year":"2011","journal-title":"Proceedings of the International Computer Music Conference"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2006.870376"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1162\/COMJ_a_00176"},{"key":"p_11","first-page":"525","author":"Surges G.","year":"2013","journal-title":"Proceedings of the Sound and Music Computing Conference"},{"key":"p_12","first-page":"78","author":"Surges G.","year":"2015","journal-title":"Proceedings of the International Computer Music Conference"},{"issue":"7","key":"p_13","first-page":"521","volume":"57","author":"V\u00e4lim\u00e4ki V.","year":"2009","journal-title":"Journal of the Audio Engineering Society"}],"container-title":["Computer Music Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/COMJ_a_00344","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,12]],"date-time":"2021-03-12T21:33:51Z","timestamp":1615584831000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/comj\/article\/40\/1\/54-69\/94572"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,3]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2016,3]]}},"alternative-id":["10.1162\/COMJ_a_00344"],"URL":"https:\/\/doi.org\/10.1162\/comj_a_00344","relation":{},"ISSN":["0148-9267","1531-5169"],"issn-type":[{"value":"0148-9267","type":"print"},{"value":"1531-5169","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,3]]}}}
