Bob Katz played the B flat clarinet from the age of 10, and his lifelong love of sound and music led him to become a professional recording, mixing and mastering engineer (since 1971). Three of his recordings have garnered the GrammyT award and many others have been lauded in publications such as Stereo Review, Audio, and Stereophile. He has written over one hundred articles for audio and computer publications, and is an inventor and manufacturer with processors and support gear in use at mastering studios worldwide. His most recent patent-pending inventions, the K-Stereo and K-Surround Processors, fill a missing link in the mastering and post- production pantheon. He has been a workshops, facilities and section chairman of the AES and has given lectures in several countries. Currently, Bob runs Digital Domain Studios just north of Orlando, Florida.
