The most exciting element is certainly the Dolby Digital Live mode (whose logo decorates Intel Audio Studio). This is a Dolby Digital 5.1 real-time encoder. In this mode, the S/PDIF digital output delivers an AC-3 signal. The available technical information, available from both Intel and from Dolby is very patchy, and it is hard to get an accurate concept of just what Dolby Digital Live is capable of. Our research shows that - at least on the computer we were using - choosing Dolby Digital Live in the output configuration deactivates the analog outputs and sends an AC-3 (Dolby Digital encoded) signal to the S/PDIF output. This signal is immediately recognized and decoded by an external decoder.
