Hi all, Well I am very proud of myself, Why?

I have bugger all knowledge of programming but I've managed after approx two months to get an EAX2 plugin for lite-c to work, "very basic at the moment".
For those who don't know what EAX2 is here is a brief rundown.

Creative®’s Environmental Audio Extensions (EAX™) add 3D reverberation
capabilities with occlusion and obstruction effects to the DirectSound™
component of DirectX or to OpenAL.

EAX is an open standard that takes advantage of any hardware-accelerated card
(such as Sound Blaster® Live!) that provides the necessary reverberation and
occlusion/obstruction processing. In either DirectSound or OpenAL, when your
application first asks for EAXsupport, the card’s audio driver is queried to see if
EAX support is available. If EAX is not available, the application will still work
properly, but will not have EAX effects.
As an open standard, EAX works not only with Creative’s cards, but also with
any manufacturer’s cards that care to take advantage of the EAX property sets.

Consider a sword clanked in a small padded cell. It should sound much different
than the same sword clanked in a large cathedral, and it’s reverberation that tells
the story. Or, consider a scream coming from the next room. The occluded
(muffled) quality of the scream tells you there’s a wall in between you and the
screamer. Without environmental audio effects, sound sources are naked and lack
warmth—the aural equivalent of a visual world without shadows, haze, and
independent light sources.

And the best part.
OpenAL re-distributable license
Creative Labs, Inc. is providing you with this OpenAL32.dll installer and other OpenAL files ("Software"). You may use and freely integrate with your software applications and distribute such throughout the world at no cost or further obligation to Creative.

If any person wishes to help me by answering any questions no matter how stupid they may seem, Please PM me. Must also know how to program the plugin

This plugin will benefit all users but as it stands at the moment it is only very basic. I hope to add more options over the next few months.

So please test it and ley me know how it goes.

Here is the link EAX2 Demo

I am using an old fire demo as an example.
There is also a dummy.wav,eax.dll and the GS_EAX2.DLL wrapper in the main program folder. DO NOT delete these.

The dummy.wav file is needed to initilize the wrapper.

There is no readme file as yet, but if you have a look at the main.c code it is self explainatory.
Oh yeah, It won't or shouldn't affect any background music playing via the media_play function.
Have fun.

Wow! Thanks!

nice work, and very good stuff you have made

Awesome stuff!
One question though:
Is it possible (with EAX generally) to adjust the environment per sound?

Thanks for the comments I really appreciate them.
Xarthor:- Yes it is afaik, I just got to figure out how.

Here is another snippet from the EAX developer guide.
----------------------------------------------------
Secondary Sound Buffers (Sound Sources)
----------------------------------------------------
DirectSound supports as many secondary sound buffers as the host system is able
to accommodate in computer RAM or sound-card RAM most cases this is 32 sound buffers. Each of these buffers
represents a sound source. Each holds a waveform table created by the
application for playback and plays back the waveform table as directed by the
application. When DirectSound is set to simulate a 3D environment, the
application can assign a secondary buffer’s position in the 3D aural world as well
as its velocity (if it’s in motion), its sound cones (for directional sound projection),
its minimum-maximum distances from the listener, and so on.

-----------------------------
Objects and Interfaces
------------------------------
Because DirectSound is object oriented, it creates each sound buffer—the primary
and any secondary buffers—as objects. To provide application control for each
sound object, DirectSound creates a standard interface (also an object) for each
sound object and ties the interface to the sound object. An application controls
each sound buffer through the buffer’s interface by calling member functions on
the interface. An application can, for example, call the member function
SetVolume on a buffer’s standard interface to set the buffer’s playback volume.

As I stated before, please be patient with me as I don't know much about programming. I'm doing it as trial and error at the moment lol.

Version 1.0 is now complete. Changes are as follows -

1) A better DEMO LEVEL with statements to where AEX2 is been used.
The three main files are - main.c, EAX_Presets.h and player.c

2) Changed from eax.dll to OpenAL sdk, Better handling and faster execution.
Option to develop into a fully fledged sound engine for GS. "Providing
if I get enough encouragement

3) Package contains the re-distribution OpenAL software and txt files,
PLEASE - It is important you read them FIRST before running the demo.

4) The BESTIST thing, It now has whopping 113 Enviromental Effects.
There are the 27 DEFAULT presests, 9 CASTLE presets, 9 FACTORY presets,
9 ICE PALLACE presets, 8 SPACE STATION presets, 9 WOOD GALLEON presets,
9 SPORTS presets, 5 PREFAB presets, 6 DOME & PIPE presets,
5 OUTDOOR presets, 3 MOOD presets, 8 DRIVING SIMULATION presets,
6 CITY presets and 3 MISC ROOMS presets.

Well guys here is the link again EAX2 Demo

So try it out and have fun. But please give me feedback.

Just need to correct myself with this one.

After further reading and understanding of how EAX works the proper answer I think - NO!. The reason is that with EAX you are changing your enviroment/surroundings and not the source. You can however manipulate the
sound source settings but the EAX Enviroment will still be the same, Just the
outcome of the sound source will have changed.

eg: If I changed the sound source to have a higher pitch and volume quiter,
and I set the Enviroment simulate an echoing tunnel the end result be
that the sound source would be of higher pitch and quiter but would still
sound like a tunnel.

This is because the EAX sets up the listener and not the source.

hell, i just saw this thread! i guess this is exactly what i wa looking for years i'll test immediately when i am at home. .hopefully it is what i am thinking that it is

thats awesome. Is it free for use?

heya, i just tried it out and it seems not to work here on my SigmaTel C-Major Audiocard.. neither your demo nor after i added it to my project.. any idea? hope to get it to work
