Digital Waveguide Modeling for Wind Instruments: Building a State-Space Representation Based on the Webster-Lokshin Model

Input impedance computation for wind instruments based upon the Webster-Lokshin model with curvilinear abscissa

Coupling between hyperbolic and diffusive systems: A port-Hamiltonian formulation

The aim of this paper is to study a conservative wave equation coupled to a diffusion equation. This coupled system naturally arises in musical acoustics when viscous and thermal effects at the wall of the duct of a wind instrument are taken into account. The resulting equation, known as Webster-Lokshin model, has variable coefficients in space, and a fractional derivative in time. This equatio...

Sound Synthesis by Simulation of Physical Models of Musical Instruments

Over the last decades, several powerful sound sythesis techniques have appeared on the consumer market. This is due to both the increased computation power of processors and the re-emergence of software-based synthesis. At the same time, the need for simple user interfaces to control complex intrument models has become apparent. In this thesis, the digital waveguide technique is used to build m...

Physical Modeling Synthesis Update∗

Recent research in physical modeling of musical instruments for purposes of sound synthesis is reviewed. Recent references, results, and outstanding problems are highlighted for models of strings, winds, brasses, percussion, and acoustic spaces. Emphasis is placed on digital waveguide models and the musical acoustics research on which they are based.

Proper Orthogonal Decomposition-Based Modeling, Analysis, and Simulation of Dynamic Wind Load Effects on Structures

Multicorrelated stationary random processes/fields can be decomposed into a set of subprocesses by diagonalizing their covariance or cross power spectral density ~XPSD! matrices through the eigenvector/modal decomposition. This proper orthogonal decomposition ~POD! technique offers physically meaningful insight into the process as each eigenmode may be characterized on the basis of its spatial ...
