History

Dolby Labs was founded by Ray Dolby in England in 1965. Ray Dolby (born January 18 1933) is the American inventor of the noise reduction system known as Dolby NR. England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland He moved the company to the United States (San Francisco, California) in 1976. The United States of America —commonly referred to as the The City and County of San Francisco is the fourth most populous city The first product he made was Type A Dolby Noise Reduction, a simple compander. Dolby NR is the name given to a series of noise reduction systems developed by Dolby Laboratories for use in analogue Magnetic tape recording In Telecommunication, Signal processing, and Thermodynamics, companding (occasionally called compansion) is a method of mitigating the detrimental One of the features that set Dolby's compander apart was that it treated only the quiet sounds that would be masked by tape noise. In Telecommunication, Signal processing, and Thermodynamics, companding (occasionally called compansion) is a method of mitigating the detrimental Dolby marketed the product to record companies.

Dolby was persuaded by Henry Kloss of KLH to manufacture a consumer version of his noise reduction. Henry Kloss (1929 Altoona PA &ndash January 31, 2002, Cambridge MA) was a prominent audio engineer and businessman who helped advance KLH is an audio company founded in 1957 as KLH Research and Development Corporation in Cambridge Massachusetts by Henry Kloss, Malcolm S Dolby worked more on companding systems and introduced B-type in 1968.

Dolby did not manufacture consumer products outright; it licensed the technologies to consumer electronics manufacturers. The verb license or grant license means to give permission The noun license is the document demonstrating that permission Consumer electronics include electronic equipment intended for everyday use

Dolby also sought to improve film sound. As the corporation's history explains:

Upon investigation, Dolby found that many of the limitations in optical sound stemmed directly from its significantly high background noise. To filter this noise, the high-frequency response of theatre playback systems was deliberately curtailed… To make matters worse, to increase dialogue intelligibility over such systems, sound mixers were recording soundtracks with so much high-frequency pre-emphasis that high distortion resulted.

The first film with Dolby sound was A Clockwork Orange (1971), which used Dolby noise reduction on all pre-mixes and masters, but a conventional optical sound track on release prints. A Clockwork Orange is a 1971 Satirical Science fiction Film adaptation of a 1962 novel of the same name, by Anthony Callan (1974) was the first film with a Dolby-encoded optical soundtrack. Callan was the title of a British television series set in the murky world of espionage that aired on ITV broadcasting over four seasons spread out between In 1975 Dolby released Dolby Stereo, which included a noise reduction system in addition to more audio channels (Dolby Stereo could actually contain additional center and surround channels matrixed from the left and right). Dolby Stereo (or Dolby Analog) was the original analog optical technology developed by Dolby Laboratories for 35 mm film prints in 1976 The first film with a Dolby-encoded stereo optical soundtrack was Lisztomania (1975), although this only used an LCR (Left-Center-Right) encoding technique. Lisztomania is a 1975 film by Ken Russell, drawn from a biography of Franz Liszt. The first true LCRS (Left-Center-Right-Surround) soundtrack was encoded on the movie A Star Is Born in 1976. In less than ten years, 6,000 cinemas worldwide were equipped to use Dolby Stereo sound. Dolby reworked the system slightly for home use and introduced Dolby Surround, which only extracted a surround channel, and the more impressive Dolby Pro Logic, which was the domestic equivalent of the theatrical Dolby Stereo. 2 0-1 channels (dolby surround labelsvg|right|200px|thumb]] Dolby Surround was the earliest consumer version of Dolby's multichannel analog film sound decoding format Dolby Pro Logic is a Surround sound processing technology designed to decode soundtracks encoded with Dolby Surround.

Dolby Stereo Digital (now simply called Dolby Digital) was first featured on the 1992 film Batman Returns.

Introduced to the home theater market as Dolby AC-3 with the 1995 laserdisc release of Clear and Present Danger, the format did not become widespread in the consumer market, partly because of extra hardware that was necessary to make use of it, until it was adopted as part of the DVD specification.
