Low Complexity Room Acoustic Modelling - Enzo De Sena

This video is of a seminar given by Enzo De Sena - Associate Professor and Director of the Institute of Sound Recording at the University of Surrey - at the University of Salford on Wed 22nd Nov 2023.

Abstract:

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.
