Description
An open-source implementation of the OpenAL 3D audio API used by applications and games to provide positional audio playback and related effects.
OpenAL Soft is a free and open-source, cross-platform software audio library that implements the OpenAL (Open Audio Library) API, an interface designed to provide hardware- and platform-agnostic audio for interactive applications such as games and simulations. It acts as a drop-in implementation for programs that target OpenAL, exposing concepts such as listeners, audio sources, buffers, and 3D spatialization so sounds can be positioned and attenuated in a virtual environment. The library supports multiple backends for audio output and input (varying by operating system), common audio data formats, and optional extensions for enhanced features such as environmental audio effects (via EFX), HRTF-based headphone spatialization, mixing/resampling controls, and device enumeration.
It is commonly used on Windows to supply OpenAL functionality for titles that ship with or depend on an OpenAL32-compatible runtime, and it is also packaged by many operating systems as a general OpenAL implementation.
