Surround Sound

Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (centre, left, and right) originating only from the listener's forward arc.

Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and presents a fixed or forward perspective of the sound field to the listener at this location. The technique enhances the perception of sound spatialization by exploiting sound localization; a listener's ability to identify the location or origin of a detected sound in direction and distance. Typically this is achieved by using multiple discrete audio channels routed to an array of loudspeakers.

There are various surround sound based formats and techniques, varying in reproduction and recording methods along with the number and positioning of additional channels.

Famous quotes containing the words sound and/or surround:

    He is said to have been the last Red Man
    In Acton. And the Miller is said to have laughed
    If you like to call such a sound a laugh.
    Robert Frost (1874–1963)

    It is not enough for us to prostrate ourselves under the tree which is Creation, and to contemplate its tremendous branches filled with stars. We have a duty to perform, to work upon the human soul, to defend the mystery against the miracle, to worship the incomprehensible while rejecting the absurd; to accept, in the inexplicable, only what is necessary; to dispel the superstitions that surround religion—to rid God of His Maggots.
    Victor Hugo (1802–1885)
