Modeling principles for time-domain simulations of wind instruments in playing situations.
Conférence invitée
Auteur
DUCASSE, EricRésumé
The development of an evolutive free software which simulates the physical behavior of wind instruments in playing situations can be based on the following modular postulates. In an object-oriented context, the virtual instrument is designed as a set of “anticipative” and lumped elements. After connection rules are laid down, new elements are progressively added and each element is separately improved. One example illustrating this approach for single reed instruments includes modeling of air columns by usual waveguide or two-port, considerations about the reed, and a key-pad model. The current state-of-the-art research in acoustics has a great potential for future extensions.

A tensor Hankel transform'' (THT) is defined for vector fields, such as displacement, and second-order tensor fields, such as stress or strain. The THT establishes a bijection between the real space and the wave-vector ...

For more than a decade, the digital waveguide model for musical instruments has been improved through the simulation of cylindrical and conical bores. But several difficulties remain, such as instabilities due to growing ...
