Kuo Perception of moving sound sources obeys different brain processes from those mediating the localization of static sound events. In view of these specificities a preprocessing model was designed based on the main perceptual cues involved in the auditory perception of moving sound sources such as the intensity timbre reverberation and frequency shift processes. This model is the first step toward a more general moving sound source system including a system of spatialization. Two applications of this model are presented the simulation of a system involving rotating sources the Leslie Cabinet and a 3D sound immersion installation based on the sonification of cosmic particles the Cosmophone.

INTRODUCTION The simulation of moving sources is of great importance in many audio sound applications including musical applications where moving sources can be used to generate special effects inducing novel auditory experiences. Motion of instruments while they are being played can also subtly affect the sound and hence the expressiveness of the performance. Wanderley et al. 1 have described for example that the motion of the clarinet follows specific trajectories
