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>.
Instructions are also provided there.

Realtek 3D SoundBack used for restoring EAX DirectSound3D features on Windows Vista and newer.
See the sound card page for details.
This file was originally downloaded from the Realtek website.

This guide was originally hosted on Creative's site (http://connect.creativelabs.com/alchemy/Downloads/ALchemy%20Quick%20Start.pdf) and provides instructions for configuring the ALchemy software to restore legacy DirectSound 3D effects to older games in Vista and newer Windows operating systems.

so, i was editing medal of honor: allied assault page, when it happened i went to the http://connect.creativelabs.com to extend my knowledge about alchemy
but.. the site is now down! (read this if you don't know what alchemy was)
all the alchemy stuff, the games recommended settings and so on.. aren't on this planet anymore
thanks to these guys i found out some links on the wayback machine (last update 2 june 2013) and on archive.is (last update 8 July 2012)
here's latest official alchemy version too, thanks to a dump of newer creative drivers
in short i think we should make a page for alchemy.
there would be lot of stuff to write, for example we could include how to install x-fi. on. realtek too (so that not only soundblaster owners enjoy this)
or write down some note about asus's GSDX eax emulation feature, available on their soundcard
with modded realtek driver i can obtain EAX up to version 4, while with this last thing i have EAX 5 too :P
and all without buying a single creative product
this other user instead claims you only need to download the universal alchemy version to achieve EAX effects up to version 4, but i haven't tried yet
for today i will be busy with RAGE (thanks to steam free weekend)
so if you want to start rough out a draft.. your work will be appreciatied
thanks everybody for the reading
