This research presents the design, usage, and evaluation of a highly generic music constraint system called Strasheela. Strasheela simplifies the definition of musical constraint satisfaction problems (CSP) by predefining building blocks required for such problems. At the same time, Strasheela preserves a high degree of generality and is reasonably(More)
The calibration of model parameters is a crucial subproblem for realistic model-based sound synthesis. This paper describes the revision of the calibration process of a classical guitar model, and extends the parameter extraction procedure to capture information about performance characteristics, such as the damping regimes, repeated plucks, vibrato(More)
A sound synthesis algorithm for the harpsichord has been developed by applying the principles of digital waveguide modeling. A modification to the loss filter of the string model is introduced that allows more flexible control of decay rates of partials than is possible with a one-pole digital filter, which is a usual choice for the loss filter. A version(More)
This paper presents a model-based sound synthesis algorithm for the Chinese plucked string instrument called the guqin. The instrument is fretless, which enables smooth pitch glides from one note to another. A version of the digital waveguide synthesis approach is used, where the string length is time-varying and its energy is scaled properly. A body model(More)
Computer Music Journal Computer Music Journal, 25:3, pp. 38–49, Fall 2001 © 2001 Massachusetts Institute of Technology. Sound synthesis based on physical modeling of stringed instruments has been an active research field for the last decade. The most efficient synthesis models have been obtained using the theory of digital waveguides (Smith 1992). Commuted(More)
