Dolby Digital is now found in the HDTV (ATSC) standard of the United States, DVD players, and many satellite-TV and cable-TV receivers.Дolby developed a digital surround sound compression scheme for the TV series The Simpsons. 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. Dolby Stereo Digital (now simply called Dolby Digital) was first featured on the 1992 film Batman Returns. Дolby developed a digital surround sound compression scheme for the cinema.

The first true LCRS (Left-Center-Right-Surround) soundtrack was encoded on the movie A Star Is Born 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. 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). Callan (1974) was the first film with a Dolby-encoded optical soundtrack. 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. To filter this noise, the high-frequency response of theatre playback systems was deliberately curtailedвЂ¦ 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. 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. Dolby worked more on companding systems and introduced Type B in 1968.Дolby also sought to improve film sound.

These units were intended for use in professional recording studios.Дolby was persuaded by Henry Kloss of KLH to manufacture a consumer version of his noise reduction. The first product Dolby Labs produced was the Dolby 301 unit which incorporated Type A Dolby Noise Reduction, a compander-based noise reduction system. He moved the company headquarters to the United States ( San Francisco, California) in 1976. The method was first used by Decca Records in the UK. patent on the technology was filed in 1969, four years later. In the same year, he invented the Dolby Noise Reduction system, a form of audio signal processing for reducing the background hissing sound on audio tape recordings. Dolby Labs was founded by Ray Dolby (1933вЂ“2013) in London, United Kingdom, in 1965.
