surround sound
Last modified: Wednesday, January 04, 2006 

Surround sound is a term used to describe a type of audio output in which the sound appears to "surround the listener" by 360 degrees. Surround sound systems use three or more channels and speakers in front and behind the listener to create a surrounding envelope of sound and directional audio sources. The term surround sound has become popular in recent years and more commonly used since the advent of home theater systems. Surround sound can be either an analog or digital system.

Also see "How Surround Sound Works" in Webopedia's "Did You Know..." section.

A history of multichannel audio from mag stripe to Dolby Digital. The first commercially successful multichannel sound formats were developed in the early 1950s for the cinema. At the time, stereophonic sound, a concept new to the public, was heavily promoted along with new wide-screen formats by a film industry feeling threatened by the rapid growth of television.
