  • Dolby Digital encoding

    I have a Creative Audigy 2 NX which supports up to 7.1 audio. I have it connected through the SPDIF audio out to a 5.1 receiver, but all sound becomes 2.0. Is there any way to have it encode in real-time to Dolby Digital 5.1, most likely through software?

    How are you recording this now? Software or hardware?

      This would be for games and other sources that already create 5.1 audio (normally played through 5.1 computer speakers).

        Hmm... have you tried Audio Hijack Pro for the Mac? Also, I'm assuming it is, your soundcard is ASIO-compliant, correct?

          This is for Windows so I don't see how Mac software will help.

          I believe my card (which is USB) works as a generic sound device without drivers if that's what you're asking.

            This isn't going to be possible for games if I am not mistaken. When using SPDIF, your feed becomes digital, which only a dolby digital decoder can decode, and I don't know of one decoder that can decode games. Your digital line is simply passing data to your decoder in which is must decode into 5.1 or 7.1, but it was not designed to determine which channel to direct gun fire and ambient noise to.

              I should generalize my question: with this card and Windows XP, can I in real time encode whatever is sent through the analog 5.1 audio connections to a Dolby Digital signal?

                What you're asking for is impossible. I tried to do the same thing when I got my Audigy and had an older 5.1 reciever. The only sound card that encodes DD 5.1 in realtime is the Soundstorm chipset on nvidia boards. You will need to hook each channel into the reciever through analog.

                  All of my receiver's analog inputs are stereo so I guess that's out, unless I could do Pro Logic II encoding.

                    I ended up just buying a new reciever. >_<
