AUX Stereo to 5.1

Qwerty_uk · Oct 5, 2004, 08:58 PM

OK, I'm a complete noob to kx, and can't quite get my head round DSP. I'm not really bothered about doing lots of tweaking, but there is one thing I'd like to accomplish:

When I'm playing tracks in WMP, the sound comes from all (5.1) speakers - great! I have a Hauppauge WinTV card, which is connected to the internal AUX on the sound card (equating to the AUX slider on the AC97 page of kx mixer). This sound only comes out of the front left and front right speakers....

(incidentally, the AC97 slider on the Master page of the mixer has no effect on this volume - if someone could explain why this is the case too, that would be great)

.... I don't want to make any changes to the setting in Surrounder, as I want to keep the sound from WMP (etc.) as it is. But I would like the sound from the AUX input to be downmixed (is that the right word?) from stereo to 5.1 so that all speakers are used.

What changes do I need to make to the default DSP layout to accomplish this?

Thanks in advance for your help. I installed the kx drivers to get around a stuttering sound problem, which has worked a treat, but if I can get this to work too, it would be an added (and long soughtafter) bonus!

use the surrounder and set it to "copy"

Qwerty_uk · Oct 5, 2004, 10:23 PM

Thanks. That'll work for switching between one and the other, but is there a way I can use DSP to automatically direct the AUX input to use this setting without affecting the usual 5.1, Surround "On" setting for wave/music/DVD use, so I don't have to keep switching back & forth?

I've tried adding an extra "surrounder" in DSP (even though I'm not sure which connections to make to it), but I get a message saying "no more free iTRAM memory".

You need to be more clear....Do you mean..you want have all your speakers playing?..or do you mean you want TRUE dolby digital 5.1...directional and all that?....

Qwerty_uk · Oct 6, 2004, 09:27 AM

The main thing is just to get it to use all speakers (or at least 4.1 stereo) to provide a 'fuller' effect. The copy mode suggested by dj_skick ought to accomplish this. I just want to get it to always apply this to the AUX source only.

As far as I know, my SB Live! 5.1 card isn't capable of producing a 'faux surround' effect using Prologic/NEO:6. I have a Creative DDTS-100 decoder that can do this from the stereo signal from my cable box. This has a switch box that directs either it's own output, or the PC output to the 5.1 speakers, so I can't use it's features with the PC sound.

Any ideas on why the AC97 slider in the Master page of kx mixer doesn't change the volume of the AUX input signal, which is on the AC97 page?

Thanks for the prompt replies, by the way.

Qwerty

ROBSCIX · Oct 6, 2004, 07:12 PM

I don't use that page very much..but you have to select the source (AUX) unmute it..Unmute the master and adjust..similar to getting a mic to work which is all through this forum if that helps...just change the description to AUX instead of Mic..hope that helps..

ROBSCIX · Oct 6, 2004, 07:15 PM

what do you mean by AUX BTW...DO you have an internal Patch to the AUX connecotr on the card...or are you refering to the LINE-IN on the back of the card?

[color=yellow]There is no AC97 slider at all in the 'Master Page of kX Mixer' that I know of..!
So what do you mean?[/color]

[color=yellow]If you mean;[/color]
[color=yellow]Simply mixing the AUX signal into every available surround channel, then Yes this [/color][color=yellow]is possible in the DSP.[/color]
[color=yellow]Just add/insert a 'Stereo Mix' Plugin for each surr.channel,[/color]
[color=yellow]then feed the AUX signal (Prolog 0/1) to all those 'Stereo Mix' Plugins.[/color]
[color=#ffff00]That is the basic principle.[/color]

[color=yellow]/LeMury[/color]

Qwerty_uk · Oct 7, 2004, 09:29 AM

ROBSCIX: The former; the TV card is connected internally to the AUX connector on the card itself.

LeMury: I'm not at my PC right now, so I can't double check, but I'm pretty sure the leftmost slider on the bottom row of the Master page says AC97 above it. Maybe it's only on mine, as I read in the helpfile that the sliders appear dynamically according to the connections available and the layout of the DSP screen.

Your 'Stereo Mix' suggestion looks like it might be what I need. I will give it a try when I have a chance, which might not be until Sunday night as I'm away for the weekend. Where will the output side of the stereo mix plugins be connected?

**dj_stick** · Oct 7, 2004, 10:44 AM

do you mean the ins and outs page (the master page is the fvery first one)

Lex Nahumury · Oct 7, 2004, 10:50 AM

>>.. but I'm pretty sure the leftmost slider on the bottom row of the
>> Master page says AC97 above it.

[color=yellow]You probably mean the 'Ins & Outs' page, not the 'Master' page.[/color]
[color=#ffff00]DJ, where are you..! [/color]
[color=#ffff00](Everyone knows I dont like and thus avoid kX mixer..

)[/color]

>>Where will the output side of the stereo mix plugins be connected?

[color=yellow]The idea is to *Insert* a 'stereo mix' in an already *existing* signal path..![/color]
[color=yellow]So the 'outs' just go where the original signal went.[/color]
[color=yellow]That is why it's called an *Insert*.[/color]

[color=yellow]So the question is more like; where do I *insert* the mixers?[/color]
[color=yellow]a. before the surrounder[/color]
[color=yellow]b. after the surrounder, [/color]
[color=yellow]or;[/color]
[color=yellow]c. before xrouting[/color]

[color=yellow]This depends on what you think sounds/works best.[/color]
[color=yellow]Just give it a try when your home.[/color]

[color=yellow]/LeMury[/color]

[color=#ffff00]EDIT:[/color]

[color=#ffff00]ahh dj there you were..lol[/color]

haha one step ahead of you

so thats why you wrote the proFX…

i take that as a yes… but im sure most of the advanced users thank you alot (i know i do)

ROBSCIX · Oct 7, 2004, 02:41 PM

oK..Please correct me if I am wrong..Which I think I may be...Isn't there anyway to patch the Aux to the KX 0/1 thus giving the "surround sound" he's after....

[color=yellow]Sure. Just mix the aux signal with 0/1 signal in DSP.[/color]
[color=yellow]Point is; ...I really dont know what "surround sound" he's after..

[/color]

[color=yellow]btw; what do you mean by "patch"?[/color]

[color=yellow]/LeMury[/color]

ROBSCIX · Oct 7, 2004, 05:49 PM

a Patch...patch cables..etc..patching signals...I use guitar patch cables to get signals going where I want them...I assumed it was a standard term patching a signal...

[color=yellow]ah, I see, yes.[/color]
[color=yellow]I thought you meant some software setting (outside the dsp) to mix the aux into fxbus 0/1. [/color]

ROBSCIX · Oct 7, 2004, 06:33 PM

no..just a patch internal..external...whatever...

What changes do I need to make to the default DSP layout to accomplish this?

You're close - it's actually "upmix" if you want to get technical about it

The suggestion other people have had of mixing AUX into the Wave should be the simplest way to accomplish what you want. If I understand correctly what everyone is talking about, then these steps should accomplish what you want to do:

- Open the DSP window
- Right-click on a blank area of the DSP window
- Select "Add Effect / Plugin" -> "Basic" -> "Stereo Mix" to add a Stereo Mix plugin module to the DSP window
- Double-click the newly added Stereo Mix module to open its Tweak menu and set both sliders to 100% (for some reason they default to zero!), then close the tweak menu
- Drag a "wire" from the FXBus0 connector on FXBus to the in1L connector on Stereo Mix. Do the same from FXBus1 to in1R
- In the same way, connect prolog's "AC97 Left" and "AC97 Right" outputs to Stereo Mix's in2L and in2R inputs, respectively
- Connect Stereo Mix's outL and outR to xrouting's WaveL and WaveR, respectively

You will probably also want to right click on the In0 and In1 inputs on xrouting and choose Disconnect Input - otherwise the AC97 output will probably get mixed into your front speakers twice and sound extra loud.

I think it's strange that in the default DSP setup, the AC97 output doesn't go through Surrounder+, even though it appears to (or am I just misreading this thread? I haven't done any tests myself)

Once I learned how kX works, I trashed the default DSP setup and made my own - which (among other things) uses the Prologica plugin to do hardware ProLogic decoding. I'd recommend it as it makes MP3s, non-AC3 movies, and the background music in games sound much cooler than when using fake Surrounder effects.
