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:

    Today we seek a moral basis for peace.... It cannot be a lasting peace if the fruit of it is oppression, or starvation, cruelty, or human life dominated by armed camps. It cannot be a sound peace if small nations must live in fear of powerful neighbors. It cannot be a moral peace if freedom from invasion is sold for tribute.
    Franklin D. Roosevelt (1882–1945)

    Immortality is what nature possesses without effort and without anybody’s assistance, and immortality is what the mortals must therefore try to achieve if they want to live up to the world into which they were born, to live up to the things which surround them and to whose company they are admitted for a short while.
    Hannah Arendt (1906–1975)
