Stereophonics

Stereophonics, most commonly called stereo, is a system of sound reproduction that creates a sensation of multi-directional perspective. This is accomplished by using two or more separate audio channels directed through two or more speakers. This way the sounds that are being reproduced give the impression of coming from different directions and of being surrounded by sound. The is the basis of not only stereo but of quadraphonics and surround sound and is used in TV, movies, and recorded music.
