Answers.Text: This answer is really general and doesn't really help the OP. Could you maybe edit it to make it more specific? Maybe add links to relevant Wikipedia pages.

  Compression codecs and methods are also based extensively in the field of Psychoacoustics. For this, I thoroughly recommend the books available from the [Focal Press](http://www.focalpress.com/audio.aspx), such as [this one](http://textbooks.elsevier.com/web/product_details.aspx?isbn=9780240521756&Search=978-0-240-52175-6&SearchCriteria=Keyword)
