    ways of achieving DD 5.1 in FMV in games...

    My question is: If game needs cinematics (FMV) with a DD5.1 sound so it needs AC3 stream inside or is there some other options ???
    Maybe a WMV file with a multichannel wma ???

    or any other ways ???

    Depends on the Hardware and Sound Engine. We have done 4 and 6 channel streaming wav files for a Xbox 360 title we are doing.

    It really depends on the video format you're working with and if the audio is streamed separately (as per a DVD) or built into the FMV.

    AC3 is the surround format used for Dolby 5.1, ProLogic II is suported on Stereo encoded files which is useful for WMV - Prologic II being LCRS (rear surrounds are not individual, and LFE/sub is calculated).

    What video format are you encoding to?

    The sound engine of the game will be FMOD EX and the FMV will have to be in 5.1.... so I need AC3 encoded stream or maybe some other way ??? Adobe Audition i have can export 6 chn wav files for surround.

    You will need to know the end FMV format and if that supports 5.1 digital or not to figure out what 5.1 format you'll be supporting.

    At the very least the stereo files should be encoded to ProLogic II.

    Yes, to produce AC3 you'll need 6 streams + an AC3 encoder.

    I know how to produce AC3 stream, but which game sound engines will passthru it to the external decoder or downmix it to stereo if player doesn't have more then 2 speakers ??? (this is unclear to me)
