Harold Hildebrand, or "Dr. Andy" as he is widely known, founded Antares Audio Technologies in 1990.
Antares develops high-tech digital signal processing (DSP) products for the music industry.
Its first product was the Infinity software. Allowing string ensembles and other complex sounds to be used in synthesizers, the program cleared the
final technological hurdle that enabled symphonic film scores and CDs you hear today to be created entirely by synthesizers.
Dr. Andy's most significant development at Antares is Auto-Tune, which puts a singer's pitch in tune, in real-time, without artifacts.
Virtually all music studios today use Auto-Tune to fix singers' intonation (a practice whose virtues music-industry pundits vigorously debate).
Dr. Andy also designs and manufactures hardware versions of Auto-Tune, and he is working on DSP products specifically for singers.
Before founding Antares, Dr. Andy worked in the geophysical industry and was a cofounder of Landmark Graphics, where he designed and implemented
software applications for 2-D and 3-D interactive seismic-interpretation products.
Dr. Andy received his Ph.D. in electrical engineering from the University of Illinois in 1976, specializing in random processes and estimation
He and his wife, Georganna, live in a redwood forest near Felton, California, where they have two dogs, two cats, and uncountable raccoons.
Dr. Andy's hobby is fine woodworking, from felling and milling native trees to building furniture and making art.
