	Historically, before the advent of widespread [[digital electronics\|digital technology]], analog was the only method by which to manipulate a signal. Since that time, as computers and software have become more capable and affordable, digital signal processing has become the method of choice. However, in music applications, analog technology is often still desirable as it often produces [[Nonlinear system\|nonlinear responses]] that are difficult to replicate with digital filters.

	===Computer audition===		===Computer audition===
			Computer audition (CA) or machine listening is the general field of study of [[Algorithm\|algorithms]] and systems for audio interpretation by machines.<ref>{{cite book \|url=http://www.igi-global.com/book/machine-audition-principles-algorithms-systems/40288 \|title=Machine Audition: Principles, Algorithms and Systems \|publisher=IGI Global \|year=2011 \|isbn=9781615209194}}</ref><ref>{{cite web \|title=Machine Audition: Principles, Algorithms and Systems \|url=http://epubs.surrey.ac.uk/596085/1/Wang_Preface_MA_2010.pdf}}</ref> Since the notion of what it means for a machine to "hear" is very broad and somewhat vague, computer audition attempts to bring together several disciplines that originally dealt with specific problems or had a concrete application in mind. The engineer [[Paris Smaragdis]], interviewed in ''[[MIT Technology Review\|Technology Review]]'', talks about these systems {{--}} "software that uses sound to locate people moving through rooms, monitor machinery for impending breakdowns, or activate traffic cameras to record accidents."<ref>[http://www.technologyreview.com/blog/VideoPosts.aspx?id=17438 Paris Smaragdis taught computers how to play more life-like music]</ref>
	{{excerpt\|Computer audition}}

			Inspired by models of [[Hearing (sense)\|human audition]], CA deals with questions of representation, [[Transduction (machine learning)\|transduction]], grouping, use of musical knowledge and general sound [[semantics]] for the purpose of performing intelligent operations on audio and music signals by the computer. Technically this requires a combination of methods from the fields of [[signal processing]], [[auditory modelling]], music perception and [[cognition]], [[pattern recognition]], and [[machine learning]], as well as more traditional methods of [[artificial intelligence]] for musical knowledge representation.<ref name="Tanguiane1993">{{Cite book \|last=Tanguiane (Tangian) \|first=Andranick \|title=Artificial Perception and Music Recognition \|date=1993 \|publisher=Springer \|isbn=978-3-540-57394-4 \|series=Lecture Notes in Artificial Intelligence \|volume=746 \|location=Berlin-Heidelberg}}</ref><ref name="Tangian1994">{{Cite journal \|last=Tanguiane (Tanguiane) \|first=Andranick \|year=1994 \|title=A principle of correlativity of perception and its application to music recognition \|journal=Music Perception \|volume=11 \|issue=4 \|pages=465–502 \|doi=10.2307/40285634 \|jstor=40285634}}</ref>
