Game Audio Engines

Game audio engines sit between a game and its sound: sound designers build events, mixes and adaptive music in an authoring tool, and a runtime plays them with 3D positioning, effects and voice management on every platform the game ships to. The paid field runs from full middleware (Wwise, FMOD, CRI ADX, Miles Sound System and the adaptive-music specialist Elias) through Unity-only frameworks (Master Audio, Sonity) and spatial audio engines (Rapture3D, atmoky trueSpatial) to the BASS playback library. Open-source options are mostly programmer libraries without an authoring tool: miniaudio, SoLoud, OpenAL Soft, Kira and SDL_mixer for playback and mixing, Steam Audio for physics-based spatial sound, FAudio for XAudio2 compatibility, Heavy (hvcc) for compiling Pure Data patches into plug-ins, barelymusician for generated music, and the pre-release Amplitude SDK as the closest open match to commercial middleware.
