In their own words
Steam Audio SDK
Steam Audio SDK is a free toolkit for adding spatial audio to games and VR/AR apps. It renders positional audio binaurally using HRTFs to model sound direction relative to the listener. Environmental features include physics-based sound propagation, occlusion, reflections and reverb. The SDK can spatialize Ambisonics audio and rotate it with listener orientation, and developers can provide HRTFs in AES SOFA format. Multicore CPUs and supported GPUs can accelerate environmental simulation and rendering. Listed integrations include Unity, Unreal Engine, FMOD Studio, Wwise and a C API. The C API is intended for custom game engines, audio middleware and digital audio workstations, and can be called from languages that use external libraries. Supported systems include Windows, Linux, macOS, Android and iOS; SteamOS is also listed as a runtime platform. Integration requirements include Unity 2017.3 or later, Unreal Engine 4.27 or later, FMOD Studio 2.00 or later and Wwise 2023.1.0 or later. The project describes its development tools as being in Beta. Steam Audio is available free to developers, subject to a license agreement.
