Get Ready To

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.

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.


Low-latency 3D audio for hundreds of sources, even on mobile. Experience physics-based sound propagation on a wide range of hardware.


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.

Integrations / Platforms

Integrated with the leading game engines and industry-standard audio middleware, and supports multiple platforms.


We look forward to your feedback upon trying Steam Audio and our development tools, now in Beta.
