Born in
San Francisco. Began his career as a recording engineer in 1963 at Casey Kasam and Bob Hudson's Emperor Productions. While focusing on recording, he maintained working relationships with several of the Los Angeles radio stations, bridging the gap between the two mediums, which enabled him to experiment with audio processing. Later at
RCA, he continued his research on his theory that audio processing should be directed toward perceived power and not on amplitude alone. The first composite tri-band processor was incorporated into the recording sessions of such artists as
Jefferson Airplane and
Carol Burnett. In 1970 Dorrough Electronics was formed to market this product. Aware of the inconsistencies in the metering of program levels, he realized that to maintain consistent listening levels that there must be a relationship between the peak and the average content, and that both should be displayed on a common scale. His development of a LED meter displaying both peak and average ballistics with dual reference points is used for audio program level indications throughout the world. Dorrough is a native of
Los Angeles and lives in
Woodland Hills, California. He is married and has five children. ==Awards and honors==
