Deliver best-in-class spatialized audio experiences with Steam Audio.
Go Beyond HRTF
Use fully-featured spatial audio attuned to the physical attributes of your in-game geometry. Combine accurate occlusion, reflection, reverb and HRTF effects for natural sounding immersion.
Simplify spatial audio design
Easy to implement and deploy for all major audio engines, game engines and platforms. Tweak high level parameters to optimize immersion and performance quickly and easily.
Tailor Fidelity
Exercise full control over spatial effects - from fully automatic physical sound simulation, to unique handcrafted tuning and everything in-between.
Why Steam Audio?
Steam Audio delivers a full-featured audio solution that integrates environment and listener simulation. HRTF significantly improves immersion in VR; physics-based sound propagation completes aural immersion by consistently recreating how sound interacts with the virtual environment.
With Steam Audio, sound appears to flow and wrap its way around mazes and corridors accurately, and adapts to changes in geometry and materials on the fly.
It's pretty great.

Features
Steam Audio offers an end-to-end spatial audio solution.
Realtime Sound Propagation
Steam Audio automatically captures and computes how sounds interact and travel through the environment.
Occlusion + Reflection
Intuitive controls let you use existing scene geometry to occlude and reflect sounds.
Virtual Reality
Rotational and positional tracking, low-latency physics-based audio, and supporting a wide range of hardware to create immersive VR.
3D Audio
HRTF-based binaural rendering that minimizes frequency coloration while providing accurate localization cues.
Performance
Low-latency 3D audio for hundreds of sources, even on mobile. Experience physics-based sound propagation on a wide range of hardware.
Ambisonics
Render physics-based audio into first or higher order Ambisonics. Spatialize Ambisonics audio using HRTF.
Baked Propagation
Calculate physics-based sound propagation at design time to reduce runtime overhead and improve quality for static scenes.
