OpenAL Soft is an LGPL-licensed, cross-platform, software implementation
of the OpenAL 3D audio API.

OpenAL provides capabilities for playing audio in a virtual 3D
environment. Distance attenuation, doppler shift, and directional sound
emitters are among the features handled by the API. More advanced
effects, including air absorption, low-pass filters, and reverb, are
available through the EFX extension. It also facilitates streaming
audio, multi-channel buffers, and audio capture.
