Perceptual evaluations of mp3 compression

  Research Project Information
Runtime: Jan 03, 2007 until Dec 30, 2011
Project coordination: Catherine Guastavino; Daniel Levitin

Mp3 compression is commonly used to reduce the size of digital music files but introduces a number of potentially audible artifacts, especially at low bitrates. In a series of experiment, we investigated whether listeners prefer CD quality to mp3 files at various bitrates (96 kb/s to 320 kb/s), and whether this preference is affected by musical genre and listeners' expertise.
