Valve has announced the release of Steam Audio, a free spatial audio solution to recreate realistic sound game sound. The royalty-free SDK is available to download and works on PC, Linux, macOS, and Android.
Steam Audio adds physics-based sound propagation on top of HRTF-based binaural audio, for increased immersion. Sounds interact with and bounce off of the actual scene geometry, so they feel like they are actually in the scene, and give players more information about the scene they are in.
Steam Audio includes such features as Binaural Rendering, Occlusion, Physics-based Reverb, Real-time Sound Propagation, and Baked Reverb & Propagation. Plugins are also available for popular middleware.
