Ray Dolby revolutionized the audio industry in the 1960s by inventing
the Dolby System, which electronically reduced the pervasive "hiss"
from analog tape sound recording, thus creating a clearer, crisper sound.
With the Dolby System, sound is passed through an encoder as it is recorded,
then played back through a decoder, dramatically lowering background
noise and hiss with none of the side effects inherent in previous attempts
at noise reduction.
Ray Dolby was born in Portland, Oregon. He received a B.S. in electrical
engineering from Stanford University and a Ph.D. in physics from Cambridge
University. He founded Dolby Laboratories in 1965 to develop his ideas
about noise reduction.
The following year, Decca Records became the first recording company
to use the Dolby System. By 1967 major record labels such as FICA, MCP,
and CBS followed suit. The 1970s saw the use of Dolby technology in
film production and exhibition, in movies such as Apocalypse Now and
