In this paper, we present an approach for the psychoacoustic analysis of musical signals based on the discrete wavelet packet transform. The proposed method mimics the multiresolution properties of the human ear closer than other techniques and it includes simultaneous and temporal auditory masking. Experimental results show that this method provides better masking capabilities and it reduces the signal\u2010to\u2010masking ratio substantially more than other approaches, without introducing audible distortion. This model can lead to greater audio compression by permitting further bit rate reduction and more secure watermarking by providing greater signal space for information hiding.<\/jats:p>","DOI":"10.1155\/2008\/346767","type":"journal-article","created":{"date-parts":[[2008,2,14]],"date-time":"2008-02-14T15:01:36Z","timestamp":1203001296000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Psychoacoustic Music Analysis Based on the Discrete Wavelet Packet Transform"],"prefix":"10.1155","volume":"2008","author":[{"given":"Xing","family":"He","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael S.","family":"Scordilis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,2,14]]},"reference":[{"key":"e_1_2_5_1_2","unstructured":"ISO\/IEC 11172-3 Information technology\u2014coding of moving picture and associated audio for digital storage media at up to about 1.5 Mbits\u2014part 3: audio 1993."},{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/5.842996"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-1684(98)00014-0"},{"key":"e_1_2_5_4_2","unstructured":"LiuQ.
