It implements the DirectSound interfaces by translating the calls to OpenAL, and fools applications into thinking there is a hardware accelerated sound device. EAX is also implemented (up to version 4) by using OpenAL's EFX extension, allowing for environmental reverb with sound obstruction and occlusion effects. Ultimately, this enables DirectSound applications to enable their DirectSound3D acceleration path, and turn on EAX. The actual processing is being done by OpenAL with no hardware acceleration requirement, allowing it to work on systems where audio acceleration is not otherwise available. Or more succinctly: it enables DirectSound3D surround sound and EAX for systems without the requisite hardware. Source Code =========== To build the source, you will need CMake 2.6 or newer (you can get it from <http://www.cmake.org/>). You can either use the CMake GUI, specifying the directories for the source and where the build files should go, or using one of the command-line programs, for example by first making sure to be in an empty directory where the build files will go (such as the provided build/ sub- directory) and running cmake with the path to the source. Once successfully built, it should have created dsound.dll. Usage ===== Once built, copy dsound.dll to the same location as the desired application's executable. You must also provide an OpenAL DLL in the same location, named as dsoal-aldrv.dll, or else the DLL will fail to work. Some applications may need to be configured to use DirectSound3D acceleration and EAX, but it otherwise goes to work the next time the application is run. Source releases, the Git repository, and Windows binaries for OpenAL Soft are available at its homepage <http://kcat.strangesoft.met/openal.html>. Instructions are also provided there.
