Duane H. Cooper
Encyclopedia
Duane H. Cooper was a physicist, who made early investigations regarding
the intricate geometry of the phonograph
stylus-groove interface.
He earned a Bachelor of Science and Ph.D. degree with honors in physics in 1950 and 1955 from the California Institute of Technology
.
In 1954, Dr Cooper joined the Coordinated Sciences Laboratory at the University of Illinois, where
he became a research professor. He developed a unified treatment of phonograph
tracking and tracing distortion by utilizing a skew transformation. In the late 1960s and early 70s, Dr Cooper contributed significantly to the theory of surround sound
multi-channel stereo.
Dr Cooper served as president of the Audio Engineering Society
(AES) from 1975-1976. He was named an AES Fellow in 1966, and received the AES Silver and Gold Medals.

Surround sound
Surround sound encompasses a range of techniques such as for enriching the sound reproduction quality of an audio source with audio channels reproduced via additional, discrete speakers. Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and...
