A cross-platform, LGPL-licensed software implementation of the OpenAL 3D audio API.
OpenAL Soft is a software implementation of the OpenAL 3D audio API that provides capabilities for playing audio in a virtual 3D environment. It handles features like distance attenuation, doppler shift, directional sound emitters, and advanced effects including air absorption, occlusion, and environmental reverb. The project is a cross-platform, LGPL-licensed fork of the original open-sourced Windows version.
Game developers, audio engineers, and application developers who need spatial audio capabilities in their software across multiple platforms.
Developers choose OpenAL Soft for its accurate implementation of the OpenAL specification, cross-platform compatibility, and advanced audio processing features that are available under an open-source LGPL license.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports Windows, Linux, macOS, iOS, and Android with backends like WASAPI, ALSA, and PipeWire, ensuring consistent 3D audio across systems as highlighted in the build instructions.
Implements EFX extensions for realistic spatial audio, including environmental reverb, air absorption, and occlusion, directly mentioned in the README's feature list.
LGPL licensing allows for modification and use in various projects, with community-maintained bindings for languages like C#, Java, and Python listed in the README.
Offers per-user and per-system configuration via alsoftrc.sample, enabling fine-grained control over audio behavior without application changes, as noted in the configuration section.
Requires CMake configuration and correct backend detection; the README warns that issues like no sound or crashes often stem from misconfigured backends, adding to setup time.
Based on the older OpenAL specification, it may lack features found in modern audio APIs like WebAudio or proprietary middleware, limiting integration with newer standards.
As an open-source project, it lacks formal commercial support, documentation, and tooling compared to alternatives like FMOD or Wwise, which offer more polished solutions.
