Ch. 6 - Virtual instruments
This chapter presents the ultimate contribution of this
thesis. Three different virtual instruments are presented: a system of
multiple plates in 3D, the nonlinear double membrane drum (a model for bass
drums and tom toms), and finally the snare drum. All these instruments are
embedded in the 3D acoustic field. They are obtained by combining together in a
modular way the components presented in the previous chapters. As such, the
resulting numerical schemes possess a numerical energy that can be used to
guarantee their stability. For each of these virtual instruments, a
description of the physical model is given, together with the implementation
details and simulation results. The implementation of these instruments as
energy conserving algorithms is original.

Sound examples
One of the perks of numerical physical modelling is the ability to play with the parameters of the system, pushing sound synthesis to its limits. Here is an example of a square, 2x2 m gong played in a 3D space.
Here is a short piece that I made just for fun, putting together sounds generated with different virtual percussion instruments I created.
