The UKAN Computational Acoustics Special Interest Group are pleased to welcome Enzo De Sena (University of Surrey) who will present a talk on perception-based methods for spatial audio. This talk will take place on Zoom. Please sign up via Eventbrite here.

 

Perception-Based Methods for Spatial Audio

Developments in immersive audio technologies have been evolving in two directions: physically motivated systems and perceptually motivated systems. Physically motivated techniques aim to reproduce a physically accurate approximation of desired sound fields but involve a very high equipment load and sophisticated, computationally intensive algorithms. Perceptually motivated techniques, on the other hand, aim to render only the perceptually relevant aspects of the sound scene by means of modest computational and equipment load. This talk will focus on perceptually motivated techniques, and more specifically in the areas of multichannel audio recording and reproduction, and room acoustics modelling.

Biography

Enzo De Sena is a Lecturer at the Institute of Sound Recording at the University of Surrey. He received the M.Sc. (Laurea Specialistica) cum laude in 2009 from the Università di Napoli “Federico II” in Telecommunication Engineering and the Ph.D. degree in Electronic Engineering in 2013 from King’s College London. Between 2012 and 2013 he was a Teaching Fellow at King’s College London. Between 2013 and 2016 he was a Postdoctoral Research Fellow at the Department of Electrical Engineering of KU Leuven. He held visiting researcher positions at Stanford University (2013), Aalborg University (2014-2015), Imperial College London (2016) and King’s College London (2018-current). He is a Senior Member of the IEEE and a former Marie Curie Fellow. His current research interests include room acoustics modelling, multichannel audio, beamforming and binaural modelling. For more information, please see www.desena.org.
