OpenAL
What OpenAL is
OpenAL is a cross-platform 3D audio API for games and other audio applications. It represents sound sources in three-dimensional space and renders them from a listener’s position, so developers can build audio that responds to movement and listening position. The site describes OpenAL as efficient, simple to use, and vendor neutral, and says developers familiar with OpenGL code will already know how to work with it.
The site lists Linux, macOS, and Windows, with runtime platforms also including BSD, IRIX, Solaris, Macintosh OS 8/9, Microsoft Xbox, and Xbox 360. Audio streaming is supported. Documented extensions include device enumeration and audio capture, plus MP3, Ogg Vorbis, WAVE, and multi-channel audio formats. Linux and standard extensions cover 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. Documentation links to the OpenAL 1.1 specification and Programmers Guide as PDFs. The downloads page offers the OpenAL 1.1 Core SDK and a Windows installer as ZIP files.
Who it suits
