EAX 4.0 introduces the spatialization of multiple reverberant environments along with an extensible library of audio effects algorithms. The Multi-Environment feature of the EAX 4.0 API allows for the rendering of multiple, simultaneous audio environments & effects in real time. Developers can now create tremendously rich & highly defined audio landscapes, by placing different 3D environments around the listener. The EAX 4.0 API also offers a host of new effects algorithms, allowing developers to incorporate studio effects such as chorus, flanger, frequency shifter, echo & many more, within a mixing framework analogous to traditional studio production systems. Like previous versions of EAX, EAX 4.0 can be used with either OpenAL or Microsoft DirectSound 3D.
