What are Dolby and Dolby Surround?
Dolby is a recording system introduced in films in 1972 to improve audio clarity. Dolby Laboratories, its creator, later expanded the system to create acoustic effects, and it is the underlying process by which dimension is added to a motion picture soundtrack. (For instance: plane engines that seem to come from the back of the theater before the aircraft appears on the screen.) It has been advanced significantly in the modern digital environment. A Dolby decoder, typically built into an A/V receiver or DVD player, is necessary to take advantage of the multidimensional effects.
