    PCI based Dolby Digital on the fly encoding is here!

    Check out this new PCI based soundcard with on the fly DD encoding, works with games and everything else it will even upconvert 2 channel to 5.1!


    HDA Digital X Mystique 7.1 gold

    You can buy one here:

    The DD on the fly encoding is software based but causes very little cpu overhead, read more here:

    It is also rumored that the drivers and software can be used on any card with the CMI8768 8ch+ chip. I do not know if the driver have to be modified to make them work or if the drivers or software can be made to work on other cards. You can download the drivers here and try your own experiments ;) :

    mmm i wonder how many standard SPDIF inputs this thing has… if its 3, you might be able to chain an Audigy 2 ZS to this thing

    Interesting idea,

    Likewise, if you had 4 stereo analog inputs on that card perhaps you could do 7.1 from the ZS thus beable to do DD EAX 4 in 7.1.

    keep them SPDIF inputs, no ADC/DAC distortion/quality loss… the ZS has 4 SPDIF outputs…

    I am going to try and get one of these cards and see,

    This card will output 16/ 41.1 - 24/48 or 24/96 so besides the EAX stuff it would be interesting to hear a CD played using ASIO and outputting 24/96 DD or ASIO upconverted to 5.1 DD.

    you won't notice a difference in sound quality. CDs are 16/44.1. Upsampling does nothing

    In my case I might because I would be out putting it in digital instead of analog to my receiver thus using a better quality DAC on my receiver.


    Besides that I am more curious about upping a 2 channel CD from ASIO to DD 5.1, I know that the settings for 5.1 on the card are adjustable in the software like the AC3Filter so it can be tweaked, I know it won't be multi channel SACD quality but I bet it would sound pretty damn good.

    Looks like you can only get two Digital inputs and you would need to purchase the Digital I/O HDA-X10 S/PDIF Input Extension board for the X Mystique card to get them.


    Here is a pic of the extension board for the curious:

    I have the card. There is a lot I like about it BUT consider this: If I disable the card (device manager) Doom3 timedemo (sound is off) increases about 5 FPS to 37. Aquamark3 also shows a similar increase. The drivers must always be using cpu. Note: this is analog out only (DDL is even worse). This means more performance hit than previously seen but a sneaky way to hide it since it wont show up in the baseline. I don't know if or how much loss is incurred with other cards. Can someone test this with other sound cards for comparison. Can someone with this card try it themselves. My system is athlon xp 2000+.

    I am seeing a big hit from this card just being enabled in device manager. For instance:

    Call of duty bench with HDA on 143.
    Call of Duty bench with HDA off and sblive enabled in device manager 176 (you can switch between the two for a/b comparison)

    Counter Strike Source stress test with HDA 138
    Same with Sblive 180 !

    Thats a giant hit ! Call of Duty OU online feels much choppier to me and I am still troubleshooting to see if its the card or sopme weird conflct. I have emailed bluegears and awit their responce.
