Inverse problem in sound synthesis and musical creation using mass-interaction networks

Sound synthesis with mass-interaction physical modeling networks can be considered as a general paradigm capable of being the central part of complete software environments for musical creation. GENESIS 3, built around the CORDIS-ANIMA formalism and developed by ACROE/ICA Laboratory, is the first environment of this kind. Using it, the artist may be facing an inherent problematic of every creation process: how to use a given tool in order to obtain an expected result. In our context, the question would be: “Considering a sound, which physical model could produce it?” This paper especially aims at presenting the frame in which this inverse problem is set and at establishing its very own inputs and outputs. However, we will also present two different algorithmic resolutions applied on quite simple cases and then discuss their relevance.
