Acoustic Ray Tracing

Acoustic Ray Tracing is a tool included in the Meta XR Audio SDK that simulates how sound propagates from its source to the listener based on actual game geometry. This includes early reflections, reverb, occlusion, obstruction, and diffraction. Acoustic Ray Tracing provides the power to quickly and easily achieve realistic acoustics for complex spaces, with controls to fine-tune the response to realize your creative vision. This is an alternative to the lightweight Shoebox Room Acoustics model (Acoustics).

By the end of this document, you’ll be able to:

  • Implement Acoustic Ray Tracing in your project.

  • Define Acoustic Ray Tracing and what developers can do with it.

  • Define default Acoustic Ray Tracing behavior.

  • Explain how and why to use Acoustic Ray Tracing.

See Getting started with Acoustic Ray Tracing for setup instructions and an overview of how to use the features.

Afterwards, see the specific feature pages for details about every control:
