What Does Dolby Digital Do For Your Sound System
There 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.
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.
Having the ability to support several channels the Dolby Digital technology enables the ability to disseminate in mono or stereo quality. Used primarily in digital equipment like CD players, Tv's and DVD's and of course the movie theaters there is a variation that is used in the video gaming industry to make that feeling even more realistic.
A man by the name of Ray Dolby began the phenomenon about 50 years ago. He started by wanting to cut down the white noise and ever present static commonly found in audio devices back then. The overall clarity was degraded by this static noise, so Mr Dolby set about finding a solution to this problem. Initially the Dolby Digital technology was used by record companies but very quickly was embraced by the movie theaters.
From these humble beginnings the technology has grown into the behemoth we know today. The movie theaters had a more compressed format that is used to take advantage of the multiple layers of channel distribution. The very first time this technology was used effectively to the masses was though a movie called "Batman Returns". The resulting sound gave the audience a more clearer sound that was appreciated by all, and as a result the Dolby Digital system was and still is used by movie theaters around the world.
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.
