    Multiple simultaneous differing audio signals?

    Okay, was that title confusing or what?
    To clarify, what I am talking about here is three separate audio signals playing at the same time. Let's say that there are three monitors, all displaying different things for different people but running off of one CPU.
    Monitor one is being used for a music player. The audio signal associated with this is being run through a processor for EQ and alignment (per driver) and then run to six speakers. This would be, say two high/full range, two mid/bass, and two bass.
    Monitor two is running a movie, and this sends a signal to a headphone jack.
    Monitor three is playing a video game, and this is to a headphone jack like monitor two was.

    Is it possible to run three audio signals like this all at the same time? I apologize for not searching more, but I am at a loss as to what to even look under... if someone has asked a similar question before a link to that is just fine.

    Absolutely...with three sound cards. I'm pretty sure OM supports independently assigning audio source and output to individual screens, and Centrafuse 3.2 will too. I don't know about RR.

    I don't believe there's anyway to do it with only one sound card, though.

    The topic your referring to is called multi-zone. Searching for that should give you a good bit of info.

    Some Links:
    OpenMobile 0.5.0.14 Released (11/27/09)
    Truly independent multi-zone

    Also note-the term multi-zone is sometimes improperly used for the following:
    * 2 screens and 2 audio outputs should be known as Dual Zone
    * 2 screens but only one audio output should be known as twin-view or dual screen

    Actually there have been some users able to use 5.1 or 7.1 sound cards as multiple output devices. It definitely takes a bit of work and its not something you'll find a step by step guide for but my recommendation would be:
    http://software.muzychenko.net/eng/vac.htm

    Of course like VegasGuy said...multiple sound cards is really the best way to do it.

    Man, I started reading about KxProject, they must have about the least informative website I have ever seen. Going into this knowing that it was drivers for sound cards I managed to glean almost no additional information from their site. Partly this is my fault because I am not as educated on the subject as I could be; partly this is their ridiculous website.
    For my three zone setup, can I run two sound cards, one of which splits for two (two channels each) signals if I use these KxProject drivers (or any others)?
    There website seems to be more focused on self promotion than actual information.

    i assume you know a little about audio processing programs like audio mulch, or console?

    that is essentially what the kx project is, except instead of relying on the pc hardware to do all the processing, the kxproject driver re-uses the audio chips on the soundcard.

    open mobile makes it easy enough that as long as your soundcard shows up with multiple outputs in windows, you should be able to use just the one card..

    its simplier than it looks for the first time

    EMU10K1/2 chipset based card's drivers from creative are very dumb, focuset on playing only. but these chipsets are much more smart than a simple AC97 or other: they have DSP calculation algorithms, for example they are able to calculate lowpass / highpass filters by hardware and several other. here are the DSP editot table from kx driver:



    FXBusX on the left side is the source, epilog on the right is the output. each input soure and output port has a pin on its module (analog, spdif, ac97 and i2s on aud_ext connector, etc). for example, if You connect directly the first 2 pin of FXBusX and epilog, then You get a simple stereo soundcard with analog output, without any DSP processing. but its a very good game to test the modules


    but there is a huge negative score for these creative cards: i tested it with a Live and Audigy1 too, and i had horrible booms on my speakers during turning ON and OFF, despite of that i had used the delayed ON/OFF feature of M4-ATX. now i swapped the creative card to an ASUS Xonar DG: the sound quality is better, and absolutely there is no noise during turning ON and OFF the whole system...

    ^what he said..

    the first time i started delving into audio processing, none of it made sense-- it wasn't until i got the sound card, and located a step-by-step demo setup(i believe there is a link on the kxproject page to it) that i finally understood how everything works together..
