The tape recorder needs to be set to the correct speed and equalization, and the magnetic tape could have some intentional or unintentional alterations. During both the creation and the musicological analysis of a digital preservation copy, the quality of the work may be affected by human inattention. This article presents a methodology based on neural networks to recognize and classify the alterations of a magnetic tape from the video of the tape as it passes in front of the tape recorder's playback head. Furthermore, some machine-learning techniques have been tested to recognize a tape's equalization from its background noise. The encouraging results open the way to innovative tools able to unburden audio technicians and musicologists from repetitive tasks and to improve the quality of their work.<\/jats:p>","DOI":"10.1162\/comj_a_00487","type":"journal-article","created":{"date-parts":[[2019,6,5]],"date-time":"2019-06-05T12:53:12Z","timestamp":1559739192000},"page":"59-74","update-policy":"http:\/\/dx.doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":14,"title":["Computing Methodologies Supporting the Preservation of Electroacoustic Music from Analog Magnetic Tape"],"prefix":"10.1162","volume":"42","author":[{"given":"Niccol\u00f3","family":"Pretto","sequence":"first","affiliation":[{"name":"Department of Information Engineering University of Padova Via Gradenigo, 6b Padova, 35131, Italy niccolo.pretto@dei.unipd.it"}]},{"given":"Carlo","family":"Fantozzi","sequence":"additional","affiliation":[{"name":"Department of Information Engineering University of Padova Via Gradenigo, 6b Padova, 35131, Italy carlo.fantozzi@dei.unipd.it"}]},{"given":"Edoardo","family":"Micheloni","sequence":"additional","affiliation":[{"name":"Department of Information Engineering University of Padova Via Gradenigo, 6b Padova, 35131, Italy edoardo.micheloni@dei.unipd.it"}]},{"given":"Valentina","family":"Burini","sequence":"additional","affiliation":[{"name":"Department of Information Engineering University of Padova Via Gradenigo, 6b Padova, 35131, Italy valentina.burini@dei.unipd.it"}]},{"given":"Sergio","family":"Canazza","sequence":"additional","affiliation":[{"name":"Department of Information Engineering University of Padova Via Gradenigo, 6b Padova, 35131, Italy sergio.canazza@dei.unipd.it"}]}],"member":"281","published-online":{"date-parts":[[2018,12,1]]},"reference":[{"issue":"12","key":"p_1","first-page":"1089","volume":"45","year":"1997","journal-title":"Journal of the Audio Engineering Society"},{"key":"p_4","first-page":"26","author":"Brock-Nannestad G.","year":"1997","journal-title":"Proceedings of the 103rd Audio Engineering Society Convention"},{"key":"p_5","first-page":"114","author":"Burini V.","year":"2017","journal-title":"Proceedings of the Colloquium of Musical Informatics"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1007\/s00799-012-0088-x"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1145\/2808200"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1109\/TASL.2009.2030005"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1076\/jnmr.30.4.289.7494"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1076\/jnmr.30.4.289.7494"},{"issue":"4","key":"p_14","first-page":"472","volume":"16","author":"Eilers D.
