Understanding and Tuning Mass-Interaction Networks Through Their Modal Representation

Sound is all about vibration, and the GENESIS environment provides an efficient way for modeling and simulating complex vibrating structures, enabling to produce rich sounds. In this paper, we propose an overview of tools recently developed and available within the GENESIS environment, allowing a better understanding on how massinteraction networks behave and introducing some enhanced tuning of their vibrating properties. All these tools try to address an inherent need of any creative process either in the physical world or in GENESIS, which is to create bidirectional connections between properties of a phenomenon, in our case, audible sounds, and properties of what produced it, here, mass-interaction networks. For this purpose, we will introduce the topological and modal representations of such mass-interaction networks and appreciate how relevant it can be to switch between these different representations to really apprehend its inner properties and those of the sounds it produces.
