Abstract
This paper is concerned with perceptual control strategies for phys- ical modeling synthesis of vibrating resonant objects colliding non- linearly with rigid obstacles. For this purpose, we investigate sound morphologies from samples synthesized using physical modeling for non-linear interactions. As a starting point, we study the effect of linear and non-linear springs and collisions on a single-degree- of-freedom system and on a stiff strings. We then synthesize real- istic sounds of a stiff string colliding with a rigid obstacle. Numer- ical simulations allowed the definition of specific signal patterns characterizing the non linear behavior of the interaction according to the attributes of the obstacle. Finally, a global description of the sound morphology associated with this type of interaction is proposed. This study constitutes a first step towards further per- ceptual investigations geared towards the development of intuitive synthesis controls.
