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.
