my card will need it as it doesn't have any method to internally route the signal.

What about looping it through the spdif? I thought I read somewhere that that was possibility.

So anyway, they really should reword their instructions then from just saying you need a card with ASIO drivers to ASIO drivers + internal software routing.

durwood, what my thinking is on using 2 pc's is, pc 1(1.2m ulv tablet) will run the front end, the actual mp3's would reside on there own networked drive, so it is accessable to either pc independantly... the "output" from the tablet would go raw into pc2, which will do all the processing & audio end, & also contain the soundcard...

now with that soundcard red has shown, I can just do 2 laptop boards, & the second may even be a duo 2 core laptop or something... I think I'm going to ditch the XCcube before I load it up, after doing all this reading on dual core.... anyone want it cheap

Ah gotcha!

Red-

I'll have to look for it tomorrow. Sorry for the suspense.

Ok I found this in my thread I had started over in THUNEAU

Cool, they have native ASIO now. I enquired about it a while a go and they didn't back then.
You will have to feed audio to the card somehow. I'm not sure their drivers offer a way of folding the signal internally like Direct Wire.
If not, see the writeup by Presto on how to stream to Allocator using Virtual Audio Cable. http://www.thuneau.com/forum/viewtopic.php?t=79 He uses on board hi def codec, but there is no reason why it shouldn't work with any sound card.
You can also always use the SPDIF input on the card.

Here is more from this thread http://www.thuneau.com/forum/viewtopic.php?t=19:

I don't have DSP in my RME card either.
I come out SPDIF from my motherboard (it's build in- Asus board) into SPDIF on the RME card. That works only partially good since the motherboard sound chip resamples everything to 48kHz. Of course I can plug in a CD player's SPIDIF output into it as well.
You could use the Prodigy for digital out, or any other inexpensive sound card with digital out for that matter.
Come to think of it, the Digi96/8 has a digital input header on the card itself (inside the computer). You might have digital audio pins on the motherbord. Check for it.
If you used ASIO output plugin for Foobar, maybe you could loop the SPDIF signal from RME card's out back to the input.
Just set the sync to internal.

The Prodigy has DirectWire drivers, which let you route Windows WDM Drivers outputs to ASIO inputs within the card. The converters on the Prodigy are supposed to be of good quality. Give it a shot and let me know. One of my Beta testers has a Prodigy card and I have not heard any complaints from him. I assume it is compatible with the Allocator.

One more post from that thread

Quote:

Great news.

Allocator (and arbitrator) work fine with the M-Audio Revolution 7.1. The only trick with a consumer 7.1 card like this is that there is no ASIO patching, routing or mixing - you only get access to the cards hardware I/O which is 2 analog inputs and 8 analog outputs. There is no way to patch in an output from a software player or a digital signal (like S/PDIF) using the ASIO driver.

This means the Allocator could very well work with any audio card that is based on the Envy 24HT or 24HT-S chipset.

You can, however, use ASIO4ALL and Virtual Audio Cable to make the card work. The Virtual Audio Cable can be used "instead" of the analog inputs of the M-Audio Card. This can be done by following these steps.

1] Set up Foobar or Winamp to use kernel streaming output.
2] Set up a virtual cable to have 2 channels 44100khz and 16 bit bitdepth.
3] Lauch Allocator and in Audio Setup select ASIO4ALL at 44100hz
4] Enter the ASIO4ALL settings via the Allocator audio setup panel
5] Enable Virtual Cable 1 INPUT as the ONLY input device
4] Enable the M-Audio OUTPUT as the only OUTPUT device.
5] Max out all buffer settings for V.A.C.1 and the M-Audio - but don't select hardware mixing.
6] Press "OK"
7] Now launch the Allocator "Audio Routing" panel
8] Select Virtual Cable 1 1 for left input and Virtual Cable 1 2 for right output
9] Select M-Audio Revo 1 through 8 IN ORDER for the outputs.

Known issues:

a] If clicking and popping occur

-Reduce Video Acceleration by "one click" and reboot
-Increase Foobar KS output latency
-Disable Windows Services you do not need
-Rarely, Wireless networking cards have cause clicks and pops
-If using a USB drive, change from "Hotplugging" mode to "Performance" mode

b] Foobar seems to more prone to clicks and pops than Winamp (when using KS output)

Cheers,
Presto

And another thread about SPDIF looping.

Ok I finally understand some things a bit more and RED you might want to re-organize/reword the links in the first post. I don't know what the best terminology is though. I think we kind of already understood this somewhat already though, but it's going to help others.

There is a difference between Console and Virtual Audio Cable (VAC).

VSTSHELL for combining/wiring/stringing VST plugins together

-Console is a VSTSHELL that works with ASIO it works for routing the cards in and outs and gives you the ability to wire up multiple VST plugin effects how you want them. It does not stream audio from the actual media player unless the output of the player is ASIO. However, I was not able to get the ASIO output plugin for winamp to work with it. maybe soemone else can try if they feel like it.

Audio Stream Capture to use with VSTSHELL programs and ASIO

-VAC is an audio streaming program designed to capture the audio signal from media players using KS/Direct sound/WDM to be routed to VSTSHELL programs or any program that needs/uses ASIO.

-Reaper is another program that captures the audio stream with the "REAroute" function built inside of it.
http://www.cockos.com/reaper/
See this thread for how it was used: http://www.thuneau.com/forum/viewtopic.php?t=71

-Directwire (Only available on ESI PRO and some Audiotrak Cards)

-Some M-Audio cards also have this capability but it is unknown which ones for sure. I heard the 410 and Firewire 410 can do it.

-Other options might be to use the SPDIF OUT looped back to the SPDIF IN if the card has both available. For details on how to do that way check some of the info in my previous post before this one.

RedGTiVR6 · 01-18-2007, 08:58 AM

Ok - changed. Let me know.

The post is starting to get a bit long so I had to trim it to fit it all.

netchris · 01-23-2007, 11:13 PM

Hey guys could one of these be used as a free alternative to Console?

http://www.toptensoftware.com/cantabile/
http://www.hermannseib.com/english/vsthost.htm

I haven't downloaded cantabile yet, but I've been playing with VST Host and what I'm thinking is that I could set the windows default sound driver as a VAC cable and then use that cable to input the the VST host. From there the audio could be equalized, crossed over, and whatever other VST goodies one might want to apply. Then audio would be outputted to an ASIO capable card.

This way any sound that any program makes will be routed through the EQ and crossover. Does this sound like a good way to do things? The only thing I'm concerned about is this kernel re sampling that I've heard about.. All of this stuff hasn't sunk in yet, so I'm not sure if the 48kHz re sampling problem applies here?

Thoughts?

Thanks guys!

-Chris

[edit]

I set everything up and found that I had skipped a step. As per one of the quotes in the first post of this thread I wrapped everything up in the Asio 4 All driver and got everything to work. (Well, it LOOKS like it works anyway. No sound comes out yet! :-P)

CPU usage is also pretty low -- only 10-15% on a 2.2GHz Celeron!

Looks good. I didn't knwo you were going to include the quotes. Holy moly. Looks good though.

Netchris-
I was looking atthose too. It might be an option. I downloaded vsthost a few days ago but never got a chance to test it. I'll check it out. Did you get a chance to play with it?

Yes, it seems to have the same functionality as Console, but is free!

[edit]

Right now I'm able to put audio into VST Host and route it to the eq31 and FA plugins. I can also see the visual displays of the plugins move and show that they are receiving audio. What I can't figure out, though, is how to get that sound to come out of the speakers!

I have it configured as per the quote in the first post of this thread, but minus the kernel streaming audio out from winamp.

netchris · 01-24-2007, 04:43 PM

Here's another 31 band graphic EQ I found. There are a lot of other fancy looking things there too :-P. I don't know if that EQ is any better or worse (or even exactly the same) as the ones that have already been posted, but I figured I'd post it up anyway!

[edit]
I did some more looking and found some more filters.. I don't know if these are IIR or FIR, but here they are:
http://home.earthlink.net/~rocksonics/FreePlugs.htm

There is also a phase plugin at the bottom of the page.. does that help us?

netchris · 01-24-2007, 07:57 PM

Here is a link to a bunch of VST filters:
http://www.audiomastermind.com/brows...5887003-1.html

I've browsed through them a bit but I'm still learning this, soo I figured I'd throw up the link so other people could look too. Maybe there is something in there that we can use.

[edit]
Ok well I have found this:
Band pass filter
High pass filter
Low pass filter

Which looks like an exact straight cut, so it shouldn't give us any problem with the phase getting out of alignment. What I don't know, however, is if a straight cut gives better/comparable/worse audio quality than a crossover with a slope like what FA has!

[edit again]
Ohh this too!

Time delay from 0-2000 ms with .1ms resolution (if you type it in)

netchris · 01-24-2007, 11:53 PM

I hate to quadruple post, but I just made a pretty-looking VST setup in VST Host, so I want to pat myself on the back and make a new post! Remember that when I came here at the beginning of this month I knew literally nothing about car audio or even audio in general. Hell, I didn't even know what a crossover was! There is still tons of knowledge out there, but I'm happy that I've learned so much in such a short time. Without further ado.. here is my proposed active setup which features the ability to work with any front end (anything that outputs audio to the default windows sound driver, which is everything really), .1ms resolution time delay, and uses only free software for all the poor college student types such as myself!

No $50 console or $60 FA here!

Well it seems that FTP access to my host is down, soo here it goes as an attachment. It seems attachments are very limited in dimensions and file size, so I tried the best I could to cram everything in there..

One thing I'll have to note is that VAC and Asio4All are both required for this, so this proposed solution isn't COMPLETELY free, but at least it won't require an ASIO card! (I don't think..)

durwood · 01-25-2007, 06:57 AM

Good work. I wonder how well it works. You are really soaking in alot. Way to do some searching and add to this project.
