He was also a co-inventor of video tape recording while at Ampex. He is the founder and chairman of Dolby Laboratories.

Biography

Dolby was born in Portland, Oregon. He was raised in San Francisco, California.

As a teenager, in the decade following World War II, Dolby held part-time and summer jobs at Ampex in Redwood City, working with their first audio tape recorder in 1949. While at Stanford University, from 1953 to 1957, Dolby continued at Ampex, working on early prototypes of video tape recorder technologies for Alexander M. Poniatoff and Charlie Ginsburg. In 1957, Dolby received his B.S. in electrical engineering from Stanford. He subsequently won a Marshall Scholarship for a Ph.D. (1961) in physics from Cambridge University, where he was a Research Fellow at Pembroke College.

After Cambridge, Dolby acted as a technical advisor to the United Nations in India, until 1965, when he returned to England, where he founded Dolby Laboratories. In that same year, 1965, he officially invented the Dolby Sound System ,although his first U.S. patent was not filed until 1969, four years later. Dolby Laboratories has been good to its founder.

Dolby is a fellow and past president of the Audio Engineering Society. Ray Dolby is a member of the Forbes 400 with an estimated net worth of $2.9 billion in 2008. [http://www.forbes.com/lists/2008/54/400list08_Ray-Dolby_KQ30.html]

Ray Dolby and his wife Dagmar have two sons, Tom and David. The musician Thomas Morgan Robertson, also known as Thomas Dolby, is no relation.

Dolby noise reduction

Dolby noise reduction works by increasing the volume of high-frequency sounds during recording and correspondingly reducing them during playback. This reduction in high-frequency volume reduces the audible level of tape hiss.
