Sound Systems and Signals: Audio/Acoustics, InstruMents
The Sound Systems and Signals: Audio/Acoustics, Instruments team develops theoretical, technological, and experimental tools addressing multiphysical systems and the sound signals they produce.
The team seeks to explore, understand, realistically reproduce, or invent sound objects in audio and acoustics, with a focus on musical instruments and extending to voice production.
More specifically, the objectives are to model, simulate, identify, and optimize these systems (voice, musician/instrument, loudspeakers, electronic audio effects, etc.), with the particularity of relying on physics to reveal intrinsic structures and benefit from them. The team develops methods for the analysis, transformation, control, and simulation of sound, as well as tools supporting design processes, within virtual, real, or hybrid paradigms.
Within this framework, the global “systems and signals” approach brings synergy from the very design of the tools, by connecting (rather than simply juxtaposing) several disciplines and scientific fields: physics, systems and control theory, differential geometry, numerical analysis, signal processing, computer science, electronics, mechatronics, and robotics. The targeted applications concern scientific, artistic, educational, and health-related domains.
