OpenAL ShortCircuit

Library to allow one to use any OpenAL library in Minecraft. It also has some workarounds for the missing AL_EXT_source_distance_model extension on Creative's OpenAL when using hardware OpenAL on a X-Fi.

Using

Add -Dorg.lwjgl.openal.libname="{path}/openal-shortcircuit.dll" to your Minecraft Java launcher setting. For example: -Dorg.lwjgl.openal.libname="c:/users/bob/downloads/openal-shortcircuit.dll.

Configuring

One can configure the library through environment variables.

• SC_OAL_LIBRARY_DEVICE_NAME, sets the device to be used, such as OpenAL Soft or SB X-Fi Audio [0001]. Also supports full enumerated names if supported by the driver.
• SC_OAL_LIBRARY_BINARY_PATH, sets the OpenAL binary/driver to use, such as C:\Windows\System32\OpenAL32.dll or C:\Windows\System32\soft_oal.dll.
• SC_FORCE_XRAM, allows the use of X-RAM when available. Disabled by default, Minecraft seems to load buffers on demand instead of loading all audio assets in one go.

How to compile on Windows

• Install MSYS2 and build packages such as cmake and g++
• git clone
• mkdir build && cd build && cmake -G "MSYS Makefiles" .. && make
