    * *Description:* MusicSpace is developed at the Sony CSL laboratory in Paris, as part of the “Active Listening” project. The original idea of MusicSpace is to introduce a constraint solver to control the location and movements of sound sources. Movements initiated by the user trigger the solver which then moves automatically other sound sources to satisfy a set of “constraints”. We have shown that a limited set of constraints (available in MusicSpaces’s constraint palette) suffice to ensure, for instance, that every movement of user would always produce a “good” mix. Other constraints can be set to produce automatic trajectories of sound sources.
