HISTORY

Creative's Environmental Audio Extensions (EAX)

Creative Technology's Environmental Audio Extensions, also known as EAX, attempted to create more ambiance within video games by more accurately simulating a real-world audio environment.

The release of Windows Vista deprecated the DirectSound3D API on which EAX relied on in 2007, so Creative Technology encouraged the move to OpenAL's EFX.

EFX

EFX is a system in OpenAL that delivers high quality sound reverberation. It is the successor to Creative's Environmental Audio Extensions (EAX).

NOTES

Reverb effects only work with the OpenAL sound backend.
