Sound Systems and Signals: Audio/Acoustics, InstruMents

Edit






The team Sound Systems and Signals : Audio/Acoustics, InstruMents creates theoretical, technological, and experimental tools based on multiphysic systems and the sound signals they produce.
Edit






The team is interested in exploring, understanding, reproducing, and inventing sound objects in audio, acoustics, focusing on musical instruments and the production of the human voice. 

More precisely, the objectives are to model, simulate, identify, and optimize these systems (voice, musician/instrument, loudspeakers, audio electronic effects, etc.) using physics to reveal and benefit from heir intrinsic structures. The team creates methods for analysis, transformation, control, and simulation of sounds as well as tools to
assist conception in virtual, real, or hybrid paradigms. 

This global approach, “systems and signals” creates a synergy in the conception of these tools, connecting—not merely juxtaposing—several disciplines and scientific fields: physics, theory of systems and control, differential geometry, numerical analysis, signal processing, computer science, electronics, mechatronics, and robotics. 

Target applications concern scientific, artistic, educational, and healthcare domains.

Major Themes

  • Physical modeling of musical instruments and voice
  • Sound synthesis based on physical modeling
  • Modeling physical audio systems and loudspeakers
  • Experimental robotic platforms: robotic bow, robotic artificial mouth to play brass instruments, robotic  apparatus at a 1:1 scale
  • Identification of non-linear systems
  • Control of non-linear systems and historical objects
  • Augmented instruments, hybrid instruments
  • Augmented lutherie

Specialist Areas

Acoustics, mechanics, non-linear systems, automatic and control, signal theory, differential geometry, digital analysis, experimentation, mechatronics, real and virtual instrument-making, sound synthesis.

Modalys

free
Modalys is an environment that lets users create unheard of virtual instruments based on simple physical objects such as strings, plates, tubes, membranes, plectrum, bows, or hammers, and making them interact. It is possible to construct objects with complex forms using a threedimensional mesh or resulting from measurements.
