RealityAudio
Open-source spatial audio package for RealityKit
The situation
Born directly out of Revenants: I needed spatial audio in RealityKit that could realistically muffle or block when a real wall or piece of furniture was between the listener and the sound source. RealityKit didn't have a simple way to do that — it meant hand-rolling matrix math and manual AnchorEntity setup every time.
Thought process
This felt like a gap worth fixing properly rather than a one-off hack buried in the game's codebase, so I pulled it out into its own package.
Engineering decisions
RealityAudio wraps spatial audio setup into a single function call — drop a 3D sound into a scene with one line — with native LiDAR-based occlusion built in, so sound realistically attenuates or blocks based on real-world geometry when the host app enables ARKit scene understanding. It ships with its own test suite and supports iOS 17+ and visionOS 1+.
