Bodo Maass

Bodo Maass is the founder and main software developer of Sygyt Software. He first began programming at the age of 11. After studying Cognitive Science (Psychology and Philosophy) at the University of Oxford, he worked on voice based human-machine interfaces for a company called MicroStrategy in Washington D.C. He subsequently returned to Oxford to become the first employee of the newly founded company NaturalMotion, where he was the lead developer for NaturalMotion’s award winning 3D animation software “endorphin”, a commercial product to synthesize human movement based on artificial intelligence research. He discovered Overtone Singing in 1994 and immediately wanted to learn this seemingly impossible art of singing two melodies at the same time. He and his teacher in this method, Wolfgang Saus, talked about the lack of good software to assist teaching overtone singers, and thus “Overtone Analyzer” was born. This work was later expanded to create the next generation of the software “VoceVista” together with the voice scientist Don Miller.
