Abstract: The INEDIT project aims to provide a scientific view of the interoperability between common tools for music and audio productions, in order to open new creative dimensions coupling authoring of time and authoring of interaction. This coupling allows the development of novel dimensions in interacting with new media. Our approach lies within a formal language paradigm: An interactive piece can be seen as a virtual interpreter articulating locally synchronous temporal flows (audio signals) within globally asynchronous event sequence (discrete timed actions in interactive composition). Process evaluation is then to respond reactively to signals and events from an environment with heterogeneous actions coordinated in time and space by the interpreter. This coordination is specified by the composer who should be able to express and visualize time constraints and complex interactive scenarios between mediums. To achieve this, the project focuses on the development of novel technologies: dedicated multimedia schedulers, runtime compilation, innovative visualization and tangible interfaces based on augmented paper, allowing the specification and realtime control of authored processes. Among posed scientific challenges within the INEDIT project is the formalization of temporal relations within a musical context, and in particular the development of a GALS (Globally Asynchronous, Locally Synchronous) approach to computing that would bridge in the gap between synchronous and asynchronous constraints with multiple scales of time, a common challenge to existing multimedia frameworks.
ANR EFFICACe Project
Florent Jacquemard participates actively in the Efficace ANR Project . This project explores the relations between computation, time and interactions in computer-aided music composition, using OpenMusic and other technologies developed at IRCAM and at CNMAT (UC Berkeley). The participant 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). There are particular focus on a number of specific directions, such as the reactive approaches for computer-aided composition, the notion of dynamic time structures in computation and music, rhythmic and symbolic time structures, or the interactive control, visualisation and execution of sound synthesis and spatialization processes [23] .
