6 OpenAL Soft is an LGPL-licensed, cross-platform, software implementation of the OpenAL 3D audio API. It's forked from the open-sourced Windows version available originally from openal.org's SVN repository (now defunct).
7 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, occlusion, and environmental reverb, are available through the EFX extension. It also facilitates streaming audio, multi-channel buffers, and audio capture.

13 To install OpenAL Soft, use your favorite shell to go into the build/
20 Assuming configuration went well, you can then build it, typically using GNU
21 Make (KDevelop, MSVC, and others are possible depending on your system setup
22 and CMake configuration).
24 Please Note: Double check that the appropriate backends were detected. Often,
25 complaints of no sound, crashing, and missing devices can be solved by making
26 sure the correct backends are being used. CMake's output will identify which
27 backends were enabled.
29 For most systems, you will likely want to make sure ALSA, OSS, and PulseAudio
30 were detected (if your target system uses them). For Windows, make sure
31 DirectSound was detected.
34 Building openal-soft - Using vcpkg
35 ----------------------------------
37 You can download and install openal-soft using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
39 git clone https://github.com/Microsoft/vcpkg.git
42 ./vcpkg integrate install
43 ./vcpkg install openal-soft
45 The openal-soft port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
49 The source package comes with an informational utility, openal-info, and is
50 built by default. It prints out information provided by the ALC and AL sub-
51 systems, including discovered devices, version information, and extensions.
57 OpenAL Soft can be configured on a per-user and per-system basis. This allows
58 users and sysadmins to control information provided to applications, as well
59 as application-agnostic behavior of the library. See alsoftrc.sample for
68 - Creative Labs for the original source code this is based off of.
69 - Christopher Fitzgerald for the current reverb effect implementation, and
70 helping with the low-pass and HRTF filters.
71 - Christian Borss for the 3D panning code previous versions used as a base.
72 - Ben Davis for the idea behind a previous version of the click-removal code.
73 - Richard Furse for helping with my understanding of Ambisonics that is used by
74 the various parts of the library.
