The first surround sound technology, Quadraphonic sound, appeared in the early 1970s.
The idea of being able to immerse yourself in 3D sound, on the other hand, did not go away with audio producers. Dolby Laboratories introduced Dolby Surround technology in 1982, which uses matrix encoding to transfer a surround sound signal to a stereo source. Dolby quickly introduced Pro-Logic surround sound technology and has since contributed to the advancement of surround sound in the home to the point where up to eleven speakers can now be used for surround sound to put the listener right in the centre of the action, whether it's a concert or a battle in deep space.
