Proposed Project Title:
Design, Formulation, and Sensor-Based Control of Bowed Virtual-Acoustic Instruments

Principal Supervisor:   Dr M van Walstijn            Second Supervisor: Dr P Stapleton (SAEL)

Project Description:  

Bowed string instruments have evolved over centuries, culminating in the established instruments of today's musical scene and practice, all of which are operated by musicians through fine control of the frictional contact between the bow and the resonating string, and amplified and spatially projected by a sounding body.

This project aims to re-invent bowed instruments in new, partly computerised form, with the instrument’s response defined and rendered in parametric form in the virtual domain. Apart from advances in the formulation of appropriately versatile numerical models, this will require the design of novel controllers based on non-intrusive sensing and associated algorithms for real-time signal processing and parameter estimation.

The design process will be informed throughout the project by dialogues with improvisation-oriented performers and aided by machine learning tools. The overall objective is to develop new friction-based virtual-acoustic instruments with similar affordances as existing acoustic instruments but with a radically larger sonic scope that can be explored via on-line parameter tuning.

The successful applicant will be part of a cross-school team of audio and music researchers at QUB and based at the Sonic Arts Research Centre (SARC), which has cutting-edge facilities for measurements and recording and projection of audio.
