Caractérisation acoustique et perceptive du mouvement évoqué par les sons pour le contrôle de la synthèse

Abstract : An important issue within sound synthesis, is to propose intuitive control strategies that are accessible to most potential users. Among fundamental sound attributes, the ones linked to motion are almost unexplored and thus cannot be easily controlled. This Ph.D. concerns the perception of time varying characteristics of monophonic sounds, which leads to the notion of motion evoked by sounds and the conception of intuitive control strategies for such motions. To address those questions, we developed several experiments based on categorization tasks and evaluations through drawings using a parameterized graphical interface. In order to help listeners focus on intrinsic sound attributes, we mainly used so-called ''abstract'' sounds for which the physical sound source is not easily recognizable. The results of those experiments enabled us to identify attributes that characterize evoked motion from a perceptual point of view, such as shape, direction and size of the trajectory. Those dimensions were further validated in an experimental protocol using sound synthesis. This work opens many perspectives, in particular within virtual reality, sound design and musical domains. The proposed methodology aimed at being sufficiently generic to be transposed to other perceptual attributes such as emotions and quality.
