Environmental audio extensions

Environmental Audio Extensions (EAX) is a special technology that allows us to hear sounds in a game or other digital software just like we hear them in real life. It makes the sound appear all around us in different directions, as if we were actually there.

Imagine you're in a forest and you hear birds chirping in front of you, a river flowing to your left and wind rustling through the trees to your right. That's how EAX makes it sound in a game. It adds several layers of sound effects to create a 3D audio experience that feels more realistic and immersive.

For example, when you're playing a game and walking through a city, EAX can change the sounds that come to your ears, based on whether you are walking on a street, inside a building, or standing near a park. It utilizes special algorithms to calculate the distance and direction of each sound source and adjust the sound depending on the environment.

In simpler terms, EAX makes the sounds in digital games and software more natural and more like reality. It helps us to pay attention to each sound and tells us what's going on around us.
