OpenAL
OpenAL is a cross-platform 3D audio API for games and other audio applications.
What OpenAL is
OpenAL is a cross-platform 3D audio API for games and other audio applications. It models sound sources moving through three-dimensional space and renders them from a listener’s position. The site describes its rendering as quick and the API as efficient, simple to use, and vendor neutral; developers familiar with OpenGL code will recognize its approach. OpenAL is listed for Linux, macOS, and Windows, with runtime platforms also including BSD, IRIX, Solaris, Macintosh OS 8/9 and OS X, Xbox, and Xbox 360. Documentation links to the OpenAL 1.1 specification and Programmers Guide as PDFs. Listed extensions cover device enumeration and audio capture, alongside MP3, Ogg Vorbis, WAVE, and multi-channel audio formats. Linux and standard extensions include playback-position and volume settings. macOS extensions include Apple Spatial Audio and static buffer support; Windows extensions include EAX 2.0 through 5.0 and an effects extension. Audio streaming is supported, and downloads include the OpenAL 1.1 Core SDK and a Windows installer, both as ZIP files.
