EAX, otherwise known as Environmental Audio eXtensions, is a positional 3D audio standard with roots in Creative's SoundBlaster Live. The standard tags in-game sounds with information about their position in the world, allowing for more realistic interactions with the player. Through EAX, positional audio is mapped to the appropriate speakers in a multi-channel setup, giving the player a sense of direction associated with each sound. EAX can also modify in-game sounds to take into account obstructions like walls and pillars, and the occlusion effect of different materials, such as wood and glass, between the player and a given sound...Check it out over here.
