- Abstract
- Acoustic synthesis for frictional sound modelling is a challenging task because of nonlinear coupling in friction phenomenon, in achieving a coherent perceptual audio-visual consistency, especially for games and virtual environments. In this paper we studied and presented an advanced friction model that simultaneously synthesizes both the high-rate sounds and low-rate video phenomenon based on lumped modal description of resonating bodies. An efficient technique and algorithmic chain are developed to demonstrate the low-cost and real time framework for the proposed discretized nonlinear dynamical frictional model using modal analysis. The developed methodology incorporates all interactions that occur in strong-contact conditions having nonlinearity and are dynamically imposed force dependent. Audio-visual animations are developed in order to implement the proposed methodology that showed a perceptual consistency in both audio and video and in reproducing sound of several materials in everyday frictional phenomenon.
