'''OpenAL''' ('''Open Audio Library''') is a [[cross-platform]] audio [[application programming interface]] (API). It is designed for efficient rendering of multichannel three-dimensional positional audio. Its API style and conventions deliberately resemble those of [[OpenGL]]. OpenAL is an environmental [[3D audio effect|3D audio]] library, which can add realism to a game by simulating [[Acoustic attenuation|attenuation]] (degradation of sound over distance), the [[Doppler effect]] (change in frequency as a result of motion), and material densities. OpenAL aimed to originally be an [[open standard]] and [[open-source software|open-source]] replacement for [[proprietary software|proprietary]] (and generally incompatible with one another) 3D audio APIs such as [[DirectSound]] and [[Core Audio]], though in practice has largely been implemented on various platforms as a [[Wrapper library|wrapper]] around said proprietary APIs or as a proprietary and vendor-specific fork. While the [[reference implementation]] later became proprietary, there are open source implementations such as [[#Implementations|OpenAL Soft]] available.
