About

=====

This project is for a DirectSound DLL replacement. 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>.
