Sound in 6 Degrees-of-Freedom VR/AR

Speaker: Prof Sebastian Schlecht, Professor of Sound in VR, Aalto University, Finland

Recent advances in tracking technology brought wide-spread accessibility to room-scale virtual experiences providing the user with movement in 6-Degrees-of-Freedom. But how to create compelling soundscapes that the spectator can freely explore? The possibility to travel through space leads to many technical, perceptual, and design challenges as complex acoustics scenes need to be adapted in real time. Purely physical acoustics rendering continues to be too demanding, particularly for mobile platforms. The most promising results rely on a mixture of efficient algorithms, perceptual subspaces, and sound design. This talk presents recent advances for sound in XR, including virtual room acoustics and insights into auditory perception and sound production in room-scale experiences.

Bio

Sebastian J. Schlecht is a Professor of Practice for Sound in Virtual Reality - a joint appointment at the Acoustics Labs, Department of Signal Processing and Acoustics and Media Labs, Department of Art and Media, of Aalto University, Finland. He received the Diploma in Applied Mathematics from the University of Trier, Germany in 2010 and an M.Sc. degree in Digital Music Processing from Queen Mary University of London, U.K., in 2011. In 2017, he received a Doctoral degree at the International Audio Laboratories Erlangen, Germany, on the topic of artificial spatial reverberation and reverberation enhancement systems. From 2012 to 2019, Dr. Schlecht was also external research and development consultant and lead developer of the 3D Reverb algorithm at the Fraunhofer IIS, Erlangen, Germany. Between 2010 and 2019, he spent half his working time as a touring and recording musician playing internationally with bands such as Mighty Oaks, David Lemaitre, and Get Well Soon. His research interests are acoustic modeling and auditory perception of acoustics, analysis and synthesis of feedback systems, music information retrieval, and virtual and augmented reality and their artistic applications. He is the recipient of multiple journal and conference best paper awards, including JAES (2020), WASPAA (2019), DAFx (2018 and 2021), and AES AVAR (2018).
