Using Dolby® Digital Live™

The Dolby® Digital Live™ technology encodes your computer’s digital audio contents to real-time Dolby® Digital streams. Using the CODEC and the Sony/Philips Digital Interface (S/PDIF) ports on the motherboard, you can send the encoded Dolby® Digital streams to an AC-3 decoder for playback on a multi-channel speaker system.

Refer to the following illustrations when converting sounds to Dolby® Digital streams.

Direct or non-encoded audio in your computer passes through the AC-3 encoder.

The AC-3 encoder converts the sound into Dolby® Digital streams.

The audio CODEC processes the streams then passes it to an AC-3 decoder through the S/PDIF out port.
