Resonant Processing of Instrumental Sound Controlled by Spatial Position
This work presents an incremental advancement in interactive music technology by integrating existing motion and pitch tracking with resonance models for enhanced instrument control.
The authors developed an acoustic musical instrument that uses a resonance model controlled by real-time spatial position of an electric violin, with pitch tracking as an additional control option, enabling interactive sound manipulation.
We present an acoustic musical instrument played through a resonance model of another sound. The resonance model is controlled in real time as part of the composite instrument. Our implementation uses an electric violin, whose spatial position modifies filter parameters of the resonance model. Simplicial interpolation defines the mapping from spatial position to filter parameters. With some effort, pitch tracking can also control the filter parameters. The individual technologies -- motion tracking, pitch tracking, resonance models -- are easily adapted to other instruments.
