DSP Seminar Abstract: This talk will provide an overview of some recent developments of the communication acoustics group at Aalto University such as signal-dependent spatial audio processing and laser acoustics. Two novel developments in the field of parametric spatial audio processing will be discussed. Firstly, A parametric spatial filtering technique that utilizes coherence-based measures between beamformers of different orders as a criterion for focusing applications. Secondly, a perceptually motivated parametric sound field recording and reproduction technique for loudspeaker or binaural renderings by mixing noisy and directionally-selective beamformers with high quality robust beamformers.
Bio: Symeon Delikaris-Manias is a last-year doctoral candidate in the Electrical Engineering at Aalto University, Espoo, Finland. His research focuses on developing techniques for parametric spatial audio analysis and synthesis with acoustic arrays. He received his M.Sc. degree in sound and vibration from the institute of sound and vibration research (ISVR), Southampton, UK, in 2008 with a thesis on inverse-filtering methods for sound reproduction systems and his B.Sc. degree in mathematics from the University of Crete, Heraklion, Greece in 2006. Between 2008-2010, he was employed by GSacoustics as an acoustic consultant, and was responsible for acoustic modeling and auralization. Between 2010-2011 he was employed as a research at the Center for Virtual Reality, Brest, France developing and evaluating sound-field recording and reproduction techniques for ship simulators for the French Navy.
