{{Short description|Sound system}}
'''10.2''' is the [[surround sound]] format developed by [[THX]] creator [[Tomlinson Holman]] of TMH Labs and the [[University of Southern California]] (schools of Cinematic Arts and Engineering). Developed along with [[Chris Kyriakakis]] of the [[Viterbi School of Engineering|USC Viterbi School of Engineering]], ''10.2'' refers to the format's slogan: "Twice as good as 5.1". However, there actually may be 14 discrete channels if the left and right point surround channels are included. He states that 5.1, a name which he himself came up with in 1987 was chosen as it was "the minimum number of channels necessary to give a sense of spaciousness".<ref>{{cite web|url=http://www.audioholics.com/education/surround-sound/audyssey-dsx-10.2 |title=Audyssey DSX 10.2 Surround Sound Overview — Reviews and News from |publisher=Audioholics |access-date=2012-11-09}}</ref> Holman and others state that higher [[sampling rate]]s, which is a recent trend in digital recording, does not have a significant perceivable effect and that the next frontier in sound engineering is to increase the number of discrete channels to meet human spatial sound perception.<ref>{{cite web|url=http://www.audioholics.com/news/on-location-articles/on-location-with-audyssey-laboratories/introducing-the-10-2-surround-format |title=Introducing the 10.2 Surround Format — Reviews and News from |publisher=Audioholics |date=2006-09-24 |access-date=2012-11-09}}</ref> {{as of|2015}}, several decoding, [[Ultra-high-definition television|UHD]], or virtual expansion processors have approached numbers as great or greater than 10.2.
