Editing Audio normalization (section)

==Peak normalization==
One type of normalization is peak normalization, wherein the gain is changed to bring the highest [[pulse-code modulation|PCM]] sample value or analog signal peak to a given level{{snd}}usually 0&nbsp;[[dBFS]], the loudest level allowed in a digital system.<ref name=Myths>{{cite web |author=Des |date=April 20, 2008 |url=http://www.hometracked.com/2008/04/20/10-myths-about-normalization/ |title=10 Myths About Normalization |publisher=Hometracked |access-date=2012-06-10}}</ref>

Since it searches only for the highest level, peak normalization alone does not account for the apparent loudness of the content. As such, peak normalization is generally used to change the volume in such a way to ensure optimal use of available dynamic range during the mastering stage of a [[digital recording]]. When combined with compression/limiting, however, peak normalization becomes a feature that can provide a loudness advantage over non–peak-normalized material. This feature of digital recording systems, compression and limiting followed by peak normalization, enables contemporary trends in program loudness.<ref>{{Cite book|url=http://ir.lib.uwo.ca/cgi/viewcontent.cgi?article=1709&context=etd|title=Audio Mastering as Musical Practice|last=Shelvock|first=Matt|publisher=University of Western Ontario: EDT|year=2012|location=London|pages=26}}</ref><ref>{{Cite book|title=Mastering Audio: The Art and the Science|url=https://archive.org/details/masteringaudioar00katz|url-access=limited|last=Katz|first=Bob|publisher=Focal Press|year=2007|isbn=978-0-240-80837-6|pages=[https://archive.org/details/masteringaudioar00katz/page/n159 168]}}</ref>
