Michael L. Dorrough (born January 1942), American inventor and audio engineer generally regarded as the “father of multi-band processing.” He is the founder of Dorrough Electronics and inventor of the Discriminate Audio Processor (DAP) in 1973, and the Dorrough Loudness Monitor. While the DAP product instantly changed audio processing in the broadcast world, the company is best known for its award winning “eyebrow” scale audio loudness monitors in widespread use throughout the motion picture, recording and broadcast industries worldwide. == Biography == 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. Always 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. He has always been an avid collector of early broadcast equipment and recordings and maintains a large collection. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Michael L.
