Yes. We talk about latency because Charles and myself come from proaudio and when working realtime live or studio this can be a disaster (nothing worth for musician returns). However up to 3ms this is acceptable for most of us. 10ms is very long! Hope you have a kind of delay control on video player, i could not stand non synced lip.
Thanks. I did follow that much though.
I'm trying to decide whether to buy a regular MiniDSP like the 2 X 8 or go with the miniSHARC which can do IIR or FIR. They say you can use a freeware app called rephase to generate the FIR filters. But apparently they don't have the GUI plugins for the miniSHARC like they do for their regular kits.
I'd like to order one of the 2 X 4 boards to play with adding subwoofers to my current speakers with really flexible crossover points and PEQ but they don't have the digital input modules in stock right now.
Anyway, I know that's getting off topic.

That makes sense. My use case is stereo only with digital out from a PC as the source.

It can be entertaining to hear people start to slur their words the first time they experience it. A sports radio station I listen to has a bunch of clips where people are speaking over a PA at sporting events and sound drunk from the delayed feedback.
I've got JRiver Media Center. It's definitely got some powerful DSP functionality but I don't know how to use it as a crossover without buying a really expensive PCI card like the Lynx AES16e. $700.
Is there a better way to get at least 7 channels out? Or just something I'm missing? I've only had JRiver installed for a couple weeks.
Thanks,
Chris
No need for a LYNX AES! you'll be struck anyway because aes is a digital format, you'll need to buy converters to convert aes to analog...
If you need 7 channels out and want to stay in progear try to see MOTU offers, usually they are cheaper units and nearly as good. It's been a long time since i've looked at what's on the market... I'll take a look and keep you in touch.
I agree with that, though I choose to use one of the paid programs, JRiver and love it. It has an excellent base for DSP including a convolver for FIR filters build in, IIR PEQ's and lots more including (basic) crossover slopes, accepts plugins and also has an excellent movie player build in with madVR. That basically solves any lip sync issues with movie playback and using FIR filters. MadVR in itself is a marvelous (free) HD video render engine with a lot of custom options and continues to develop still. Excellent renderer and it can also be used in other (free) players.
Possibilities are endless. Lots can be done with free programs, I just happen to like JRiver too much after running a 30 day demo (that was about 4 years ago). I just couldn't give it up. May skip an update every now and then but I just love what it can do. Using mobile phone as remote and even stream to that... So if you do have that PC....
Yep, I would have to use external DACs with something like the LYNX. The expense of all that is another reason I'm looking at a hardware DSP rather than using JRiver.
I don't know my way around pro gear at all. This Crown XLS I got for driving subwoofers is the only thing I have. I had a Behringer pro amp and Feedback Destroyer before but that's it.
I've been considering using a car audio DSP as well. There are some really nice all in one products out there with slick GUI interfaces that just don't seem to have an equivalent in the home audio world.
So your budget should be many thousands of dollars because converters using aes input are not cheap ones... We talk about serious pro gear here!
Something like Prismsound or Weiss audio, or Lavry...
But i don't think you'll spend so much money or you'll have to sell your house!
In fact last time i looked around their still was PCI on motherboards and if you have one on your PC and can find drivers for windows you are using something like that should be perfect:
M-Audio Delta 1010LT
second hand should be less than 100usd and quality is ok!
But if you cannot find any of the 2 in bold just forget.
Maybe other could give you advice about that, me i just know stuff used in the industry i've worked in so prices are not in the same range.

Ok, so you're using a PC DSP as a crossover into 8 digital channels and the external USB does the digital to analog conversion for all channels?
Or does the USB module go HDMI or something to an AV receiver?

PCI is getting more scarce but can be found on some workstation type PC's.
I tracked down a Lenovo Workstation just for that PCI bus.
That could be a great solution! I own an old PCI+rack card AARdVARK PCI (8in/8out)24bit/96khz which as really great sound (it's now Antelope audio). If you can find one with drivers running on win jump on it! It should be less than 100usd and quality it's on par with Apogee and the like...
O.T.: Wesayso, i just discovered your epic build of line array 2 days ago! Hats off to you, really, it's stunning build! Very very impressive.

Thanks, actually it sounds even better than it looks (lol). Would have been a lot harder to do without JRiver though. The thing I love about a program like that is anything and everything is possible. A separate DSP will have certain limits.
You want bigger?
Here is an Analogue Systems (not Solutions!) modular to aim for. ;-)

It depends on the budget you are ready to invest. But in a way you're right: i could never perform auto acoustic correction or phase linearisation (using FIR, i've got a very complete allpass module on mine) with mine. But everything else is possible. But it's not cheap, that's a fact.
Please stop with synth porn!!!!
It's time to go sleeping and i'll have wet dreams!
