Ambisonics

The subject will doubtless continue to fascinate scientists and engineers for some years to come. (Philip Nelson, Physics Today, June, 2020)

Franz Zotter studied Electrical and Audio Engineering at the University of Technology and University of Music and Performing Arts in Graz, Austria. By the time receiving his diploma in 2004, he had the opportunity to join the Institute of Electronic Music and Acoustics as a researcher, later on also lecturer. In 2009, he finished his Ph.D. dealing with the topic of spherical arrays for sound radiation analysis and synthesis, and he was awarded the Lothar-Cremer medal by the German Acoustical Society (DEGA) in 2012 for the work on this topic and Ambisonics, and he became tenuring assistant professor in 2019. He is a member of the DEGA, chairs the DEGA TC on virtual acoustics, he is a member of the Audio Engineering Society (AES), and the society of German Tonmeisters (VDT). Matthias Frank studied Electrical and Audio Engineering at the University of Technology and the University of Music and Performing Arts in Graz, Austria. After receiving his diploma in 2009, he joined theInstitute of Electronic Music and Acoustics in Graz as a researcher and lecturer. In 2013, he finished his Ph.D. on the spatial and timbral properties of auditory objects created by multiple loudspeakers and models thereof, in particular considering Ambisonics. He is a member of the Audio Engineering Society (AES) and the German Acoustical Society (DEGA), and the society of German Tonmeisters (VDT).
