Description

TECHNICAL DESCRIPTION

This invention describes a digital simulation process of a non linear interaction between an exciting source and a wave in a resonator. It can be used for the real time digital synthesis of signals representing an oscillating phenomenon such as the sound produced by a musical instrument.

The invention includes:
– An efficient process of digital transcription in the time domain of the physical variables characterizing the waves in a resonator, using combinations of simple elements whose parameters are explicitly expressed as functions of the propagation medium, the geometry and the boundary conditions of the resonator.
– An explicit digital process of resolution of the nonlinear equations linking the physical variables in the case of woodwind and brass musical instruments.
– A real time control of digital synthesis, which makes specific use of physical playing parameters that can be piloted with standard commercial devices.

INDUSTRIAL APPLICATIONS

The invention could be used in synthesizers and more generally for sound synthesis.
