What Does Dolby Digital Do For Your Sound System
January 14th, 2008There are a few technologies available in sound systems these days but one in particular seems to be remembered the most, Dolby Digital. When we go to the movies we are exposed to a pre movie advertisement for this technology with an impressive display of it’s capabilities. The “Dolby Digital Surround Sound” system can be found in nearly all new sound equipment which includes DVD’s and TV’s that are bought from electrical stores, so it is no wonder the average consumer is familiar with the Dolby logo.
The Dolby Digital title refers to the digital enhancement of sending and receiving audio signals for audio equipment. As they were one of the predecessors of this type of technology and also being marketed well, the system is now widely accepted as being the leader in the field and ensuring it’s wide spread use in most audio systems.
The 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 Digital was born 50 years ago by a man by the name of Ray Dolby, hence the Dolby Digital name. He wanted to eradicate or reduce the white noise and static that plagued the audio equipment at the time. Clarity of audio was degraded by this static noise so when the solution he found was released it quickly became the standard for record companies and movie theater production.
From there, the 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 sound. The technology became popular and spread to thousands of movie theaters in a very short time.
The future of the 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.
