Ray Traced Spatial Audio for GigaLights

Bring your world to life with ray-traced Spatial Audio, powered by GigaLights - Infinite Lights for Unity. Simulate realistic sound propagation and occlusion. Built for Unity URP, BIRP and HDRP.

Supported Unity Render Pipelines:

Built-in Render Pipeline (BIRP), Universal Render Pipeline (URP) and High Definition Render Pipeline (HDRP).

Ray tracing support:

• Hardware ray tracing: Available on compatible DX12 hardware and PlayStation 5.
• Software ray tracing: Available across all supported platforms and graphics APIs.

GigaLights automatically uses hardware ray tracing when available and falls back to software ray tracing otherwise.

Current supported platforms*:

• Windows (DX11, DX12)
• Linux (Vulkan)
• MacOS (Metal)
• iOS (Metal)
• Android (Vulkan)
• WebGL (WebGPU)

Working on support for:

• VR
• Playstation 4
• Playstation 5
• Xbox One
• Xbox Series
• Nintendo Switch 2

🔊Bring your world to life with GigaLights - Spatial Audio for Unity!🔊

Great visuals create atmosphere. Convincing audio brings it to life. GigaLights Spatial Audio adds a new level of realism by making sound respond to the environment around it. From narrow corridors and dense city streets to vast open spaces, give your players a more immersive experience where sound feels like a natural part of the world.

🌊Ray-traced spatial audio

Extend your GigaLights setup with dedicated ray-traced spatial audio. Simulate how sound interacts with your scene’s geometry, accounting for obstacles and surrounding surfaces. Create a more convincing sense of distance, direction and space, helping audio sources feel grounded in your environment.

• Occlusion & wall attenuation: Obstacles reduce and muffle sound, with attenuation responding to wall thickness and multiple layers.
• Sound through openings: Sound can travel through doorways and around corners, shifting its perceived arrival direction toward the opening.
• Directional reflections & dynamic reverb: Add echoes from surrounding surfaces and room reverberation that adapts to the environment, with adjustable reflection bounces.
• Automatic surface response: Approximate acoustic absorption from supported visual material properties, with optional surface overrides for extra control.
• HRTF headphone spatialization: Give supported 3D sources and reflections a stronger sense of direction and elevation when listening on stereo headphones.

⚙️ Built around your existing audio

Existing Unity 3D AudioSources are discovered automatically, while you retain control over clips, playback, volume and mixer routing. Spatial Audio uses the shared GigaLights ray-tracing scene, without requiring additional colliders or manually placed reverb zones. Choose from Performance, Balanced and High quality presets, and adjust wall attenuation and reflections & reverb to suit your scene.

🧩Part of the GigaLights family

Spatial Audio is an optional module for GigaLights. Combine it with the dedicated Global Illumination and Reflections modules to bring together contact shading, indirect lighting and reflections in a shared ray-tracing and denoising workflow.

Please note that this asset requires the base GigaLights asset to function.
