About Us

Dr. Jouko Viitanen

CEO / Main Engineering Designer

The CEO and main engineering designer, Dr. Jouko Viitanen received one of the first patents on polyphonic samplers, U.S. Pat. 4502361, while consulting at Allen Organ Company, Macungie, PA, USA during 1982-83.

In present DSP era, a sampler is quite a trivial device, but at that time it required ASIC electronics, for which Allen was pioneering.

After that time Jouko did a career in research at Tampere University of Technology and VTT in Finland, working mainly in digital image processing, pattern recognition and automation related projects, and received several patents on various topics. He has practical experience on several generations of digital signal processors.

After leaving VTT in 2014, he concentrated on the design of DSP based electronic musical instruments. That work has resulted in the first product of Audiospektri.
