Sound Core3D has been certified for Dolby Digital decode.
Dolby Digital Live works inside your PC or game console while you play, encoding the 5.1-channel audio in the game's audio engine into a Dolby Digital output bitstream. This makes the audio compatible with all Dolby Digital 5.1 playback systems, including A/V receivers, home-theater-in-a-box (HTiB) systems, and integrated 5.1 speaker systems. It also makes connecting your PC or game console to your home theater easy. All you need is a single S/PDIF connector.
7.1 adds two additional speakers to the more conventional six-channel (5.1) audio configuration.
