ESR12 Project Title: Physics-Based Source Modelling with Time-Variant Parameters
This project will belong to the work stream of Work Package 1, which focuses on modelling and simulation of sources and their near field characteristics. Research in this project will be conducted in collaboration with the University of Performing Arts Vienna (MDW), and will be further informed through industrial engagement by ARTIM.

Objectives: One of the key tasks in accomplishing further step changes in aural immersion involves replacing sample-based strategies with interactive, procedural source models based on realistic simulation of vibrating structures. Using a rigorous physical modelling framework, these will render physically consistent changes in the source signal in response to a human actor interacting with the embedded vibrating objects. Progress on this topic can partly build on a steadily advancing body of numerical techniques for simulation of musical instruments, which have become increasingly viable for real-time application, and are now seeing direct application in the design of new virtual-acoustic instruments.

From an engineering perspective, such interactions can be framed in terms of continuous human-driven adjustment (i.e. time-variance) of physical model parameters. This project seeks to introduce extended parameter time-variance in physics-based simulations of musical instruments and other sound-emitting mechano-acoustic vibrating systems for the following two complementary purposes:

• Exploration: discovery and design through fine-tuning global system parameters (e.g. dynamically adjusting the tension of a virtual-acoustic string or the mass density of a virtual-acoustic plate).

• Articulation: local parameter changes associated with physical human actions (e.g. sounding a virtual-acoustic membrane through repeated mallet striking with varying force and excitation position while dynamically exerting local hand damping control on a specific region of the membrane surface).

The principal research challenge that the project will address is enabling such control and interaction introducing minimal artefacts (which would degrade the sense of immersion) for both elementary and complex systems consisting for linearly and nonlinear coupled vibrational subsystems, with specific focus on avoidance of undesirable or unphysical energy changes that typically arise with existing discretisation approaches. Addressing this challenge will involve deriving numerical models that allow the specification of precise trade-offs between desired energetic behaviour, parameter adjustability and computational efficiency; both finite difference and modal expansion forms will be explored in this context.

Expected Results
1. New numerical methods and models for simulation of vibration and sound produced by virtual-acoustic source systems (including musical instruments) under time-variance of system parameters. 2. New methods for analysis of stability and energy behaviour for such systems. 3. Off-line and real-time realisations for demonstrating the models in the contexts of virtual reality, music performance, and audio processing.

Research Environment
The successful applicant will be part of and contribute to the Systems & Sensors research theme within the School of Electronics, Electrical Engineering and Computer Science, and will be based in the Sonic Arts Research Centre (SARC). SARC (http://www.sarc.qub.ac.uk) brings together researchers in composition, performance, musicology, electrical engineering, computing, acoustics, perception, sound recording, interaction design, broadcast, critical improvisation studies, sound art, aesthetics and media theory, forming an interdisciplinary research environment with over 60 academics and postgraduate students.

The purpose designed SARC building features a state-of-the-art Sonic Laboratory, several multichannel studios, an Interaction Lab, and a VR/AR Lab. The ESR will interact regularly with other researchers in the network, and will conduct part of the research in collaboration with the team based in the Department of Music Acoustics – Wiener Klangstil (IWK, https://iwk.mdw.ac.at/) at the University of Performing Arts Vienna (MDW).
