'''Surround''' [[sound]] [[encompass]]es a range of [[techniques]] for enriching the sound [[reproduction]] [[quality]] of an audio [[source]] with audio [[channels]] reproduced via additional, [[discrete]] speakers. The [[three]]-[[dimensional]] (3D) [[sphere]] of [[human]] hearing can be [[virtua]]lly [[achieved]] with audio channels above and below the [[listener]]. To that end, the multichannel surround [[sound]] [[application]] en[[circle]]s the [[audience]] with surround channels (left-surround, right-surround, back-surround), as [[opposed]] to "screen channels" (center, [front] left, and [front] right), i.e. ca. 360° [[horizontal]] [[plane]] (2D).

''Surround sound'' [[technology]] used in [[cinema]] and [http://en.wikipedia.org/wiki/Home_cinema home theater systems], video game consoles, personal computers and other platforms. Commercial surround sound media include videocassettes, [http://en.wikipedia.org/wiki/DVD-Video DVD]s, and [http://en.wikipedia.org/wiki/HDTV HDTV] [[broadcasts]] encoded as [http://en.wikipedia.org/wiki/Dolby_Pro_Logic Dolby Pro Logic], Dolby Digital, or DTS. Other [[commercial]] formats include the [[competing]] DVD-Audio (DVD-A) and Super Audio CD (SACD) formats, and MP3 Surround. Cinema 5.1 surround formats include Dolby Digital and DTS. Sony Dynamic Digital Sound (SDDS) is a 7.1 [[Cinema]] [[configuration]] which features 5 [[independent]] audio channels across the front with two independent surround channels, and an LFE.

Most ''surround sound'' recordings are [[created]] by [[film]] [[production]] companies or video game producers; however some consumer [http://en.wikipedia.org/wiki/Camcorder camcorders] have such [[capability]] either built-in or available separately. Surround sound [[technologies]] can also be used in [[music]] to enable new [[methods]] of artistic [[expression]]. After the [[failure]] of quadraphonic audio in the 1970s, multichannel music has slowly been reintroduced since 1999 with the help of SACD and DVD-Audio formats. Some [http://en.wikipedia.org/wiki/AV_receivers AV receivers], stereophonic systems, and computer soundcards contain integral [http://en.wikipedia.org/wiki/Digital_signal_processors digital signal processors] and/or digital audio processors to [[simulate]] surround [[sound]] from a stereophonic [[source]].
