Analysis of physical models, analysis by means of physical models Sound synthesis and frequency analysis by the mean of CORDIS-ANIMA masse-interaction networks

This paper focuses on methods for model analysis and for modelisation dedicated to signal analysis. Especially regarding mass-interaction physical networks and the audio signals they produce. In the context of sound synthesis for artistic creation relying on physical modeling, such kind of methods are of central interest in a way to provide guidance to users. In the first part of this paper, we will focus on the harmonic oscillator built with CORD'S-ANIMA. Then, starting with this very simple and well known element, we will present two approaches for calculation and analysis of the properties of signals produced by a model, the latter being either linear, non-linear, simulated or no yet, in real-time or not. The outcomes of both of these approaches will then be exemplffied.
