Several well-established approaches to physical modeling synthesis for musical instruments exist. Finite-difference time-domain methods are known for their generality and flexibility in terms of the systems one can model but are less flexible with re

The simulation of nonlinear components is central to- virtual analog simulation. In audio effects, circuit elements often include devices such as diodes and transistors, mostly operating in the strongly nonlinear regime. Mathematical models are of th
The Odeo Cornaro in Padua (Italy) is a well-preserved XVI Century octangular music space (from Latin the ottangulo) surrounded by communicating smaller halls. Inspired by Roman classicism, the Renaissance architect Falconetto designed such coupled vo

This work addresses the problem of the struck piano string. This system is highly nonlinear, and a sound representation of the energy balance is therefore necessary in any time stepping routine used in simulation, in order to preserve stability. Many

String vibration represents an active field of research in acoustics. Small-amplitude vibration is often assumed, leading to simplified physical models that can be simulated efficiently. However, the inclusion of nonlinear phenomena due to larger str

Collision modelling represents an active field of research in musical acoustics. Common examples of collisions include the hammer-string interaction in the piano, the interaction of strings with fretboards and fingers, the membrane-wire interaction i

In this paper, a complete simulation of a trombone using finite difference time-domain (FDTD) methods is proposed. In particular, we propose the use of a novel method to dynamically vary the number of grid points associated to the FDTD method, to sim

For physical modelling sound synthesis, many techniques are available; time-stepping methods (e.g., finite-difference time-domain (FDTD) methods) have an advantage of flexibility and generality in terms of the type of systems they can model. These me

This paper presents a number of finite difference time domain (FDTD) schemes to simulate the vibration of prestressed beams to various degrees of accuracy. The Timoshenko, shear and Euler–Bernoulli models are investigated, with a focus on the numer
