help to find solution with second audio card

[SeregaZ]

PC has 2 sound cards.

main is stereo, 2.0 channels. play song, or game, or movie. basic audio function.

second card is 4.0 quadro - it must to play, in real time, same sound, that plays in main card. but! this audio card must to have some additional driver or audio player, where i can set equalizer each(!) channel.

now players basicly have equalizer, that tune both channels of stereo at the same time (or quadro). but i need to tune each channel by separate. for example: front left plays bass, front right hi, rear left one part of middle more closer to bass, rear right second part of middle more closer to hi. this is happen in real time, both sound cards must to play sound synchronously.

any idea?

Hi,

i would do that with an older creative audigy
Just get one with an emu 10k2 soundchip from ebay or so. These are pretty cheap.

The advantage with these cards is, that there is a special driver available.
This driver gives you full control over the inputs, outputs and the dsp of the soundcard.
It's possible to route everything you want. You can add effects, equalizer... where you want,
the possibilitis are endless.

For your problem i wouldn't use 2 seperate soundcards, because it's hard (or impossible?) to let them play the same thing exactly in realtime.
But with the audigy you have 6 or more channel which you can use for everything you want.

Why not just use a single card? Unless you have some stipulating reason that they need to both play different streams in real-time for some reason..

As far as separating channels and routing frequencies, it sounds like what you need is DSP software of some sort.. i.e the program I use for my HTPC, J River Mediacenter, has a DSP plugin which lets me control the volumes of individual channels, as well as redirect frequencies to them.

Dadido3, ebay in my country is big lottery this stuff will be lost on the way. our system of delivery is ***

Zach, i have old PC with only 2 channels audio and i have old PCI sound card with 4 channels. some dj's programm can do this - work with 2 sound cards and play same sound in both, but they not have equalizer to each channels so i though maybe some one programming this software on PB... and it is only player, i need in some kind of driver programm, that detect all sounds in first sound card in background and stream it in second card with this 4 channels equalizer.

Have you tried looping the output of Soundcard 1 to the Line-In of Soundcard 2?

You could connect them with a simple 3.5mm Stereo Male->Male

Something like this http://www.newegg.com/Product/Product.a ... 6882021054

Zach, i like it! but male to male need to some upgrade 2.0 have only 1 out channel, so male jack need to additional female jack for speaker. i can do it - it is not problem. but equalizer options still remain

[SeregaZ]

i am a idiot one switcher in programm of sound driver and 2.0 become to 5.1

so now i need to make some 6 channels equalizer. i think equalizer itself can be found in audio players example in PB. and for send sound to 6 channels - maybe this is present in some dvd players code example.

5.1 sound card + AC3Filter = almost that i need rear channels play not 100% same that front. it is a little problem for configuration... and this AC3Filter is work with windows media player and did't work with winamp. how to make marry between them?

[Zach]

Try setting Winamp to default system output (Wavout or DirectSound)

I've never tried running AC3 filter for its on the fly encoding properties, much less with Winamp. But it should be a DirectShow filter, so you probably need to make sure Winamp is rendering through DirectShow somehow.

If that doesn't work I've no idea

You'd probably do better asking on an Audio/Video forum where dealing with AC3 Filter and ffdshow, etc. Are much more common tasks.

this forum is better by my plan i want to programm this player. PB is only one language, that i know. but now, i think, do this will be unreal.
