Are there any free EAX addons? Also, does the one sold here, "Enhancement Expansion Pack" allow you to specify EAX effects as robustly as the Creative Labs EAX Control Panel in the AudioHQ?

A friend of mine recently bought an OEM Audigy and it didn't come with AudioHQ, so he can't create any custom voice modulation effects for his mic. He's wanting to join me in my fun on voice chat because I keep creating interesting effects for my voice. I tried letting him use my driver CD but it complained that his card is OEM and refused to install

So what I need specifically is to tap into EAX, to be able to specify which sources are modified by EAX. Basically 100% on Mic, 0% on Wave. I need to be able to access all of the EAX effects (Flanger, Pitch Shifter, Ring Modulator, etc).

Lastly, ideally, it would be able to leave the effects in place after the DB program closes down. Some computers don't like DBPro and the program we're voice chatting on at the same time. (The program we're using is an OpenGL based avatar chat, and DBPro is DirectX... My system handles it fine but I don't know how well his will.)

OpenGL has no audio, but that is moot, since any shared resource that is opened first by an application that is not willing to share will suffer that same malaise.

And that's a real shame for you both, I like all of Creative's crap, even the stupid 8-bit parrot. Has he spoken to them about it? They never seemed secretive about any of it to me, quite the contrary, they rule!

You might get good results trying to use the Windows MultiMedia dll, winmm.dll and its associated dll set. I am just now arriving at my need to do this very thing you are mentioning, but...I want to see what Windows will offer me.

Well my point is more the some video cards don't like DBPro programs and Second Life to be open at the same time.

I seriously doubt that the stock Windows API has EAX stuff, concidering it's a Creative Labs specific API.

I never said it did, merely that you have access to the MCI interface that it exposes (and thus the microphone, and wave and MIDI and everything else), so issues with regard to sharing Creative Labs API are not a concern, as you deal with Windows, not a driver, or DirectX, either, but sure...I'd recommend again that you go see what documentation Creative has for doing that, since that is your wont.
Cheers.

Hey, Lucy, I found it! Here
