Audio Tracing v1.0.2 (5.6) for Unreal Engine

Audio Tracing is a plugin that integrates real-time Ray Tracing technology into Unreal Engine’s Sound system with the goal of achieving more realistic sound propagation simulation. It physically calculates complex acoustic properties—such as the position, direction, and reflections of sound sources within a real-time, changing game environment—and applies them to the listener, providing a realistic and spatial sound experience.

This plugin automatically calculates sound reflections and occlusion via real-time ray tracing. This approach makes it possible to implement realistic sound variations based solely on the world’s geometry, without the need to set up separate audio occlusion volumes or complex Blueprint logic.
