In this presentation, I will present a few scientific and technological tools that we develop to model physical systems and to process sound signals. The introduction will be devoted to a short description of some activities of the Project-Team S3 in physical modelling, nonlinear systems, robotics, sound synthesis and sound analysis. Then, selected works will be deepened.
- Port-Hamiltonian systems: sound synthesis based on the guaranteed-passive simulation of physical models.
- Fractional filters: modelling and simulation of a class of low-pass filters, the slope of which can be continuously tuned from 0 (unit gain) to -6 decibel per octave (1 pole filter).
- SnailAnalyser: a frequency-domain analyser that delivers in real-time an intuitive representation of sounds based on the chromatic alignment of spectral active zones.
Sound examples and demonstrations will be given along this presentation:
