pbrAudioShaders

Physically based rendered audio shaders.

Physically plausible collisions sound for rigid body simulation.

Features

• Physically-based reverse engeniering of rigidbody animation: Uses Hertzian contact theory for accurate collisions modeling
• Multi-object, multi-collision support: Handles complex scenes with multiple interacting objects
• Multiple collision type support: Handles impact, scraping, sliding and rotation.
• Material-aware synthesis: Considers material properties (Young's modulus, density, damping, etc.)
• Modal synthesis: Generates audio from object vibration modes
