Virtual-Acoustic Instruments

 

Physical Modeling techniques can be employed to develop new, acoustic-sounding musical instruments for highly nuanced performance that, through the physicality of the control parameters, afford a learnability and virtuosity similar to that of traditional acoustic instruments. The principal novel feature offered by such virtual-acoustic instruments is the extended range of design and control options, such as the adjustment of material and geometrical properties. In order to fully exploit the musical potential, crude simplifications in the derivation of physical models should be avoided as much as possible, while simultaneously allowing for real-time performance. These demands lead to high computational costs, and also present new challenges regarding numerical modeling and controller design. To address these, novel strategies and solutions are investigated in the following topic areas:


- numerical algorithms for physical modeling
- computation architectures for physical modeling
- design tools for rapid hardware creation
- sensing and signal processing for parameter estimation and controller design
