EFFICAC(e)

The aim of this project is the development of tools exploring the relations between computation, time and interaction in computer-aided composition. It is based on OpenMusic and other technologies developed at IRCAM and at CNMAT.

We consider computer-aided composition out of its traditional "offline" paradigm, and try to integrate compositional processes in structured interactions with their external context. These interactions can take place during executions or performances, or at the early compositional stages (in the processes that lead to the creation of musical material). We focus in particular on a number of specific directions, such as :

• Reactive processes for computer-aided composition
• Control and management of time structures in computation and music
• Interactive control, visualisation and execution of sound synthesis and spatialization processes
• Rhythm and symbolic time structures

Several critical antagonisms in the domain of computer music are addressed in this project (signal versus symbolic approaches, off-line versus real-time…). By bridging high-level computer-aided composition systems with other disciplines and frameworks such as sound processing, spatialization and gestural integration, it includes control and interactions in abstract and expressive compositional models.
