Lukas Gölles is a researcher based in Graz. He studied Electrical Engineering and Audio Engineering at the University of Music and Performing Arts Graz. He completed his master’s degree in 2021 with a thesis on the curvature of arc-shaped sound sources. He subsequently pursued a PhD at the Institute of Electronic Music and Acoustics, focusing on immersive sound reinforcement technologies, which he successfully completed in 2025.

His research focuses on the development and optimization of spatial sound reinforcement systems, as well as on (immersive) recording techniques and online reproduction of three-dimensional audio content. In addition, he works on methods to improve the directional resolution of Ambisonic impulse responses.

Alongside his academic work, he is active as a sound engineer, combining research and practical application.

Matthias Frank is PostDoc at IEM and deals with virtual acoustics, Ambisonics, musical acoustics, and psycho acoustics. He studied electrical and audio engineering at Graz University of Technology and University of Music and Performing Arts (KUG) and graduated in 2009. In 2013, he finished his PhD at KUG about the perception of auditory events created my multiple loudspeakers.
