I'll grab screenshots tomorrow morning. I'm working a 15 hour day today, then going bowling 'till 3am.. heh

I don't completely remember, but I can mute all of the hardware and software inputs. Unfortunately, console ties the ASIO outputs to the software inputs for channels 1-10, so if I mute either the software input or hardware output, it mutes the channel. (a screenshot will better explain it) but I can route the HW outputs to: SW input, monitor mixer (for ch 1+2 and spdif only), spdif in, spdif (channels L/R swapped), and hardware inputs. I might be mistaken about the muting though.

I don't mind using the loopback at all. If it makes things work, it makes 'em work. I ordered two off the 'bay for $10 shipped total so it's not like it's money wasted.

Oh, remember how I was asking you about multiples of these cards? Well apparently in other apps, cubase, logic, etc, they add inputs/outputs, so instead of having 1-10, you get 1-20. very cool.


All that does is connect HW spdif out directly to HW spdif in. A passthrough of sorts.

I wish I had the options that the mac users do for this card. Their control panel software can directly connect to ASIO in AND out... heh

Isn't that the same thing? Now I'm confused. :blush:


Very cool indeed. If someone needed more than 8 channels, I don't think you could go any other cheaper route. I'm going to keep it in mind if I need to do something really crazy. I just feel somewhat bad recommending this card to you when what I thought wasn't completely true, but no one said this would be easy. You can always return it or sell it if it doesn't work I guess.


No kidding. Finally, a vaild reason Mac trumps PC.

It takes the hardware spdif input, and replicates it to software spdif input, and then to hardware spdif output. There is no processing available to the stream.

what happens:
HW spdif in -> SW spdif in -> HW spdif out

I think what you're thinking is
SW spdif in -> HW spdif out -> HW spdif in ->

Loopback would be SW spdif in -> HW spdif out -> HW spdif in -> console -> SW analog out -> HW analog out ->


No joke, I was tossing the idea of virtualpc... HAH. not.


Oh I'll get it to work. I think all issues will be solved with spdif loopback. I got my card for I think 135 shipped NIB from the 'bay. If I can get a method together for getting this to work, you can't beat that.

Here's the M-Audio console. From what I've come to understand, they all use the same console software.

Whenever I muted the SW analong inputs (and accessed HW output directly via ASIO), all of my echoing and reverb disappeared. However, I still have popping and clicking that makes the recordings sound like on old damaged vinyl.



This is using asio output and using console to capture sound through "mixer".

durwood

Well actually here is what I was thinking if you look at output screen.

on the right side, set the box below the spidf out to spidf in. EDIT: NEvermind it looks like you assign it an output, not an input.

Then in winamp select spdif out. and select spdif in console as your input and all the analog outs for you out. SO it should look like this.

winamp/DVD/VIDEO -> SW/HW SPDIF out -> HW/SW SPIDF IN -> console -> SW Analogs outs -> HW Analog outs.

Maybe it doesn't work like that, but that is what I was thinking.


so if you mute the software analog inputs it works right? You just get popping and clicking? The popping and clipping is from too low of a latency setting. in the ASIO sample setting box on the last screen set it as high as you can go. My Audiotrak can only go up to 1024, and works pretty well with only slight clicking. If I could go a bit higher on the latency I think it would completely disappear.

to go sw/hw output -> sw/hw input I need the loopback cable But that's what I'm going for.

I have a support topic open with M-Audio about loopback not working.

Even with asio buffer size to 4096 samples and winamp directsound buffer set to 20000ms, I still get popping and clicking. Is there a latency setting in Console? On the ASIO tab it's locked at 6ms input and 5ms output and I can't seem to change it via Console or M-Audio console.

When playing with the spdif output in the control pannel, it doesn't matter what I set it to, because despite the fact that I'm outputing directly to SPDIF out, right now I'm pulling audio into console from the monitor mixer.

More good stuff.

Another vst plugin chainer/routing/mixing program

Plogue Bidule -$75

Stereo Crosstalk cancelation + ambiance

V.I. Suite (fL fR good for ambiosonics)

Very briefly played with them, so don't ask me too many questions.

Wow, I think I hit the jackpot. Completely untested by myself, but I think this one is really awesome without even trying it yet. I will tonight!

Rubberfilter - Free

What is it? A filter/crossover plugin with 6db/oct up to 384db/oct if your computer can handle it. Holy brickwall filter batman!


Phasebug - Free

Phase adjustment.

His whole site actually has some pretty useful plugins.

More great and useful VST plugins,

Ambiosonics

Swiss plugins

Emigrator plugin

Panorama plugin

York Plugins

I tried this one out last night, no need for time delay or level adjustment with this bad boy. Just measure your angles of direction of speakers from straight line if front of you and it's angle of elevation.

Well, i do not see this posted anywhere on here via searching, so here it is..

ARC system from IK Multimedia

Although the write ups are fairly vague, it looks like this package includes a Mic and software. Using the mic to take measurements, the software will calculate EQ and delays using Audyssey's MultEQ®, then export as a VST plug in with the calculated EQ/delays.

I do not see any crossovers, but maybe that could be worked around. Maybe one could make different plug-ins to put in after the crossover in Console. After reading about it I am not sure how many Plug-ins it will make.. Not cheap at around $600 though, but may be worth it if it can do total EQ and delays for a whole system..

IK has updated their ARC page with significantly more information than was originally posted. After looking at their page and thinking more about the technology, I think this technology would work fine for CarPC users.

Because the system uses a microphone to measure the response at various points in the vehicle (I especially like this idea, being able to tune for primarily driver seat listening, but still trying to improve passenger listening as well), it compensates for total system response, not individual driver response. The time delay, EQ, and phase correction it implements will apply to the total sound signal.

Sounds to me like you would just drop the plug-in on your total audio stream in console, with your cross-over plug-in behind it. Based off the home-audio examples on the page, they have the ARC plug-in running on the PC and then passive crossovers on the individual speakers or crossovers on the external audio equipment. Having the crossover plug-in downstream of the ARC plug-in should achieve the same thing. The ARC system won't automatically tune your crossover points and slopes, but tuning 1 thing manually is a hell of a lot easier than tuning 4,5,6 or more things simultaneously without the ARC system.

I'm seriously considering this technology for my audio install in my new truck this fall. If I do end up using it, I'll let y'all know how it works out

so i found a 4 way FIR crossover that even does room correction.. and its free! check it out:



[edit]
you could probably use this to create your impulse response file.

RedGTiVR6

that looks an awful lot like a rip off from frequency allocator...strange.

good find though!

regardless of whether the gui bears any similarities, this has totally different innards. FA is an iir filter with a parametric eq while crossvolver is a fir filter with drc.

crossvolver is actually the only fir crossover i've been able to find, which is nice because no phase correction is necessary. i know PA can correct FA's phase alignment, but i don't know if there is any other advantage to fir over iir. i made another thread about that..

[edit]
here's a free 3 way crossover. it's iir, but easier to set up than crossvolver, and i'm pretty sure you can just set your slopes to 24dB/oct and stay in phase.. but correct me if i'm wrong about that.

netchris

it seems the guy who made the fir crossover also made an iir version:



but you can only go up to 24dB/oct.. i don't know if that's really a limitation though.
