Real-Time Synthesis of Sound Effects Caused by the Interaction between Two Solids

We present the implementation of two sound effect synthesis engines that work in a web environment. These are physically driven models that recreate the sonic behavior of friction and impact interactions. The models are integrated into an online project aimed at providing users with browser-based sound effect synthesis tools that can be controlled in real time. This is achieved thanks to a physical modelling approach and existing web tools like the Web Audio API. A modular architecture was followed, making the code versatile and easy to reuse, which encourages the development of higher-level models based on the existing ones, as well as similar models based on the same principles. The final implementations present satisfactory performance results despite some minor issues.
