I cant find any code examples of EAX being used by openAL. Does anyone even use it? This sucks.

Do EAX environment operations only apply to mono waves?

You need this file included: http://ftp.berlios.de/pub/worldspace/Mingw...nclude/al/eax.h

and you request it like this:

  alIsExtensionPresent("EAX2.0");
  palubyte FnName = "EAXSet";
  eaxSet = alGetProcAddress(FnName);
  FnName = "EAXGet";
  eaxGet = alGetProcAddress(FnName);

  //set the effect
  TAluInt Env = EAX_ENVIRONMENT_BATHROOM;
  eaxSet(DSPROPSETID_EAX20_ListenerProperties,
        DSPROPERTY_EAXLISTENER_ENVIRONMENT or
        DSPROPERTY_EAXLISTENER_DEFERRED,
        0, &Env, sizeof(TALuint));
  // Commit settings on source 0
  eaxSet(DSPROPSETID_EAX20_BufferProperties,
        DSPROPERTY_EAXBUFFER_COMMITDEFERREDSETTINGS,
        source, null, 0); //where source is the source to apply it to.. i think....
  // Commit Listener settings
  eaxSet(DSPROPSETID_EAX20_ListenerProperties,
        DSPROPERTY_EAXLISTENER_COMMITDEFERREDSETTINGS, 0, null, 0);

this is translated from object pascal so please ask somebody else if there's problems with it.. i'm not really an expert into c++ :blush:

That header is from 1999! I am pretty sure EAX 4.0 exist nowadays.

Check out these links for more info:
EAX 2.0
alEax.c

Yes, EAX 1 -> 4 is only applied to mono sources. Stereo support is promised in version 5. Until then, just place 2 3D sources in the room, and pan them.
