Description:

This project focuses on the interaction of autonomous, realistic and musically-gifted virtual agents with sound synthesis systems.

Our interest lies both in the analysis and the synthesis of percussive gestures. One the one hand, the analysis focuses on timpani gestures and aims at extracting relevant movement features. On the other hand, the synthesis part involves an inverse-dynamics control chain of a mechanical virtual agent model. For improved realism, we will use physical modelling for sound synthesis.

We expect that the virtual agent simulation will show the relevance of gestural control in animation, since gesture influence acts on the fine nature of the produced sound and on the spatial and temporal coordination of movements in charge of musical expressivity.
