Wed 22 Nov 2023 12:30 – 13:30. This seminar will be in person (338, Peel Building). A teams link is also available to join online.
In order to achieve a high level of immersion and externalisation in interactive applications it is important to render room acoustics appropriately. Room acoustic modelling methods can be classified on a scale that goes from very high computational complexity and high physical accuracy to low computational complexity and accuracy. At the former end of the scale are methods based on space and time (or frequency) discretisation of the wave equation, followed by geometrical acoustics models, which make the simplifying assumption that sound travels as rays. On the other end of the scale are artificial reverberators, i.e. perceptual models that do not render the acoustics of a specific room but rather render certain desirable perceptual qualities of reverberated sound. This seminar will focus on methods that aim at bridging the gap between physical and perceptual models, with the objective of achieving reasonably accurate perceptual rendering with a low computational complexity.
Enzo De Sena is an Associate Professor (Reader) and Director of the Institute of Sound Recording (IoSR) at the University of Surrey. His research interests include auralisation, room acoustics modelling, sound ﬁeld reproduction, beamforming and binaural modelling. He received the PhD degree from King’s College London, UK, in 2013. Between 2013 and 2016 he was a postdoctoral researcher at KU Leuven, Belgium. He held visiting researcher positions at Stanford University, Aalborg University, Imperial College London and King’s College London. He is a Senior Member of the IEEE and a member of the IEEE Audio and Acoustic Signal Processing Technical Committee. He currently serves as Associate Editor for the EURASIP Journal on Audio, Speech and Music Processing and IEEE/ACM Transactions on Audio, Speech and Language Processing. He is a recipient of an EPSRC New Investigator Award and a co-recipient of best paper awards at WASPAA-21 and AVAR-22. He is due to chair the 27th International Conference On Digital Audio Effects (DAFx-24). For more information see: desena.org.
