Revolution 5.1 card
M-Audio has introduced the high-definition surround sound card for PCI-based computers. Built upon the same architecture as the Revolution 7.1, Revolution 5.1 offers "a multitude of features for today's power user." M-Audio designed the Revolution 5.1 with gamers in mind. Today's gaming technologies, such as EAX, OpenAL, A3D, DirectSound and Sensaura, are built right in allowing 3D audio positioning and realistic environmental simulation. Revolution 5.1 also features low CPU usage, an important factor for fast visual response in gaming. Revolution 5.1 also brings DVD movies to life with up to 5.1 surround sound.
