Dolby Laboratories, Inc. (often shortened to Dolby Labs) is an American company specializing in audio noise reduction and audio encoding/compression. Dolby licenses its technologies to consumer electronics manufacturers. Dolby Labs was founded by American Ray Dolby (1933-2013) in the United Kingdom in 1965. He moved the company to the United States (San Francisco, California) in 1967. The first product Dolby Labs produced was the Dolby 301 unit which incorporated Type A Dolby Noise Reduction, a compander based noise reduction system. These units were intended for use in professional recording studios. Dolby was persuaded by Henry Kloss of KLH to manufacture a consumer version of his noise reduction. Dolby worked more on companding systems and introduced Type B in 1968.
