About Us

Dr. Andy

Dr. Harold (Andy) Hildebrand is the founder of Antares Audio Technologies and serves as its CEO and Chief Scientist. 

Dr. Andy (as he is widely known) received a Ph.D. in electrical engineering from the University of Illinois in 1976, specializing in random processes and estimation theory. He initially worked in the geophysical industry for Exxon with Dr. John Mouton in Exxon Production Research, mainly in the area of seismic processing research.

Andy and John left Exxon about 1979 to start a geophysical consulting  company named Cyberan. One of the projects at Cyberan was to develop a geophysical workstation for Seiscom Delta. During this time, they meet Robert Limbaugh, who introduced them to Roice Nelson. The four founded Landmark Graphics and leveraged the Seiscom workstation to successfully promote a 3D interpretation workstation to venture capitalists. 

Landmark Graphics Corporation

Dr. Andy headed technical development at Landmark and was the mind behind the software of the Landmark workstation. Dr. Andy designed and implemented software applications for 2D and 3D interactive seismic interpretation products. He also developed seismic data processing software for digital filtering, deconvolution, wavelet extraction, and wavelet substitution.  

Dr. Andy created and managed the development of the first integrated software framework, known as OpenWorks, which unified and standardized database interface and schema, user interface and inter-task communication in a distributed computing environment across Unix platforms. 

Andy was Senior Vice-President/Chief Technical Officer, Assistant Secretary, and a Director of the company. His tenure included taking the company through an IPO and listing on NASDAQ.  Dr. Andy left Landmark in 1989. 

Antares Audio Technologies

Antares Audio Technologies (originally called Jupiter Systems) was founded by Dr. Andy in 1990 to develop DSP-based products for the music industry. Antares quickly established itself as a creative innovator of high technology digital signal processing products.

The first of these products was the Infinity software. This program allowed string ensembles and other complex sounds to be used in sampling synthesizers. This was the final technological hurdle which allowed symphonic film scores and much of the music heard today to be created entirely by synthesizers. 

As an early pioneer in digital audio plug-ins, Dr. Andy's most significant development at Antares is undoubtedly Auto-Tune. This technology allows a singer's pitch to be made in tune, in real time, without artifacts, while preserving all of the nuance of the original performance. Despite the ongoing debate over the "morality" of pitch correction, Auto-Tune remains the worldwide standard in professional pitch processing, being used in the vast majority of all vocal recording.

In 2004, Dr. Andy began focusing on the development of other DSP products specifically for vocalists.  These include real time physical modeling allowing a singers' vocal tract to be modified, the automatic generation of vocal doubling and and choirs, and most recently, harmony generation. This allows a single voice to be transformed in five part harmony, creating singers with different vocal ranges and even different genders.

Most recently, Dr. Andy has pioneered the application of Auto-Tune pitch processing technology to the guitar market. The resulting Auto-Tune for Guitar technology is poised to revolutionize the guitar in the same way that Auto-Tune revolutionized vocal production.

Dr. Andy holds multiple patents for his technology developments at Landmark and Antares. He and his wife, Georganna, have two dogs, two cats, uncountable raccoons, and live in a redwood forest near Felton, California. Dr. Andy's hobby is woodworking, from felling and milling native trees to building fine furniture.
