EAX

post #1 of 15
Thread Starter 
Guys, I used to have a SB live which had hmm i think EAX but had never used it , this card was with me since 99 and now has gone kaput due to my idiocity I shorted it somehow but anyway, now that I have a SB 5.1 VX and was checking EAX under COD 4 (no more a gamer but just was testing ) well the thing when I enable EAX I have to select the ambiance and that screws up the sound it sounds hollow.

EAX's main function is ambiance so if that screws up the sound, don't use EAX.

EAX will not work well in windows 7 to begin with. The EAX technology is based on DirectSound, which MS stopped supporting with windows vista.

it's not ambiance, it's positional cue audio. EAX is not dead with Windows 7, rather it just travels a different processing path than pre-Vista.

Not technically. EAX was designed to be processed through the hardware on the creative card via DirectSound. Since MS removed Directsound with vista, most audio processing is done in software emulation now.

Let's see, according to EAX's motto:

"The aim of EAX is to create more ambiance within computer and video games by more accurately simulating a real-world audio environment."

And I don't even know where you are going with positional cue audio...what the hell is that? There's nothing in EAX's technology description that involves positional cues, they are all environmental profiles.

Those profiles are for external use, to apply to your normal desktop or overtop of the in-game experience. "real world" means actually changing the sounds in a game based on where you were in a level to more accurately reflect your environment. it doesn't describe "positional cues" but EAX is able to make the direction a sound is coming from more apparent when you're using 2 channel speakers/headphones.
For example, the original halo was able to use EAX. say you were inside one of the bases on the island map and a tank fired outside, EAX made the sound reverb like it would if you were in a tunnel, but it sounded normal if you moved outside. Without EAX it sounded the same whether you were inside or outside.

One of the main reasons MS dropped DirectSound in windows vista was because of the OpenAL audio emulation standard and the higher adoption of surround-sound equipment which made EAX obsolete.

If you still want to get EAX effects from games like halo you can use creative's ALchemy program. ALchemy takes the Directsound/EAX cues and wraps them into the OpenAL stream.
