What is Dolby Digital Surround Sound
One of the major players in the surround sound game is the Dolby Digital technology that is used by many of the new systems. When we go to the theater, they often advertise that the movie we are about to see is being broadcast with “Dolby Digital Surround Sound.” No doubt, this is supposed to impress the moviegoers and home theater system purchasers. But does anybody actually know what Dolby Digital technology is or what it consists of? There are many variations within Dolby Digital technology, but the basic idea remains the same throughout the variations.
Specifically, the term “Dolby Digital” refers to a digitally enhanced encoding system used by many audio devices for sending and receiving sound signals. Dolby is the name of the laboratory that perfected the technology and it is one of the forerunners in the competition for a bigger and better audio experience. There are competitors in the audio industry, but Dolby is the most prominent and widely-used currently.
Dolby Digital technology can support either a single channel or several channels so that audio can be broadcast either with stereo or monophonic qualities. It is used mainly with digital devices (DVD player, CD player, digital TV, movie theaters, etc.) and there is a special type of Dolby Digital technology that can be used to enhance your gaming experiences in a more realistic way.
Dolby technology started out about fifty years ago by a man named Ray Dolby. His idea was to reduce the white noise and static that occurred on many sound sources, such as audio tapes. The white noise on many sources is characterized by static-like noises that take away from the clarity of the audio. This technology began to be used by record companies, but quickly moved on to be used in movies and theaters.
From there, Dolby Digital technology came about. It was a more compressed format of sound that was best experienced in a movie theater. In 1992, Batman Returns was the first movie to be broadcast at a movie theater using the Dolby Digital technology. It combined a stereo sound (right and left channels) with a more crisp audio quality. The technology became popular and spread to thousands of movie theaters in a very short time.
The future of Dolby Digital continues to improve on the technology that the Dolby laboratory has already created. It has made the movie viewing experience an experience of being fully immersed in sound and sight – both at the theaters and at home. This technology comes standard in the USA and is included in almost all of the DVD players and other audio/visual devices sold today.
With an ever-changing home theater system technology, Dolby continues to stay ahead of the competition in bringing quality audio enjoyment to the avid, and even occasional, movie lover.
