1 ACROE - ACROE

The CORDIS-ANIMA physical modeling system is one of the oldest techniques for digital sound synthesis via physical modeling. This formalism which is based on the mass-interaction paradigm has been designed and developed by ACROE in several stages since 1978. The aim of this article is to enlighten some special and particulars features of this approach by exploiting it mathematically. Linear CORDIS-ANIMA (CA) models are studied and presented using several useful system representations like system function input/output external descriptions, state space internal descriptions, finite difference model, modal decomposition, electrical analogous circuits, CA networks and digital signal processing block diagrams.
