Dayton OmniMic Precision Measurement System - Page 60

post #1771 of 2086
That's what I do. Personally, I don't agree with it in theory and would prefer these measurement softwares using 5/7.1 signal. With multichannel audio being pretty straightforward on computers and most computers having HDMI now, I don't see why we don't see that more often.
post #1772 of 2086
Depends on what you are measuring. Omnimic comes with left and right test tone sweeps and L+R test tone sweeps. What is really needed, and is in the works, is a DVD/BD with separate tones for each of the 6 or 8 or 9 (for subs too) speakers.
post #1773 of 2086
Yes. I am eagerly awaiting such a test disc to come out. Bill has mentioned a 5.1 dvd but I would LOVE a 7.1 BD or some form of multichannel discrete test tones.
post #1774 of 2086
in the meantime, most pre/pro's have a Party mode that sends the stereo signal to the surrounds; then you unplug all of the speakers except the one you want to measure

I know but... I don't want to have to do that. tongue.gif
post #1776 of 2086
The PE folks are trying to get the dvd out in a few weeks. Im waiting on a first copy to check out.
post #1777 of 2086
Thank you Bill. Great product especially for someone like me who has "test anxiety."

Bill, my Omnimic software doesn't display properly on a 1920x1200p screen (my computer monitor). Some selections/items aren't displayed. Is there a way around this?
post #1779 of 2086
Theresa,

A quick work around until you can get an official answer is to go to right click on desktop, select personalize, and adjust the resolution.

Theresa,

At the upper right of the screen should be the Windows control frame buttons. Click the one that looks like a box in front of a box, and the form should reduce to its smallest size. When not full screen, you can also stretch it to other sizes. Click that button again and it will go back to full screen.

I use the small screen often on a netbook, which is what the minimal screen is designed for.

Bill

The various options get real small if I change to small type and when minimized to its smallest size. More and more computers have high res screens so I think this should be allowed for.

Scott, this is facilitated easily with an all active 7.x system tongue.gif

But yes, until I went all active, this was a pain in the arse.


Bill, thanks for all the steady improvements.

Hi guys,

 

I am a little confused and wonder if someone can set me straight.

 

I have the V1 OmniMic (with the small USB connector on the mic body). I have just downloaded the latest version of OM software (4.02) and I notice that the test tracks refer to a different CD than the one that came with my OM. I have downloaded the relevant zip file from the Parts Express website.

 

My question is this: right above the link for the test tones CD download it says "OmniMic Audio V2 Test Tracks". Does this mean that the test CD in that download can or cannot be used with the setup I have - V1 mic, OM software Ver 4.02?  Thanks.

Theresa my monitor is also 1920x1200 and Omnimic displays full screen for me. My Omnimic version is 3.10 dated 1-8-2012. Is yours a different version?
post #1785 of 2086
Yes, 4.02. It can be made to fill the screen but then some items are "off screen."

no the original signals. cd will still work. Either Mic will work with all cds or dvds.

Hi has anyone time aligned a main speaker with there sub?

Please can you advise.

I am running dual stereo subs, Velodyne DDs through my stereo outputs on my Yamaha Z9.

The IR peaks don't appear. as per manual.

Thank you in advance
post #1788 of 2086
if they are co-located with your mains, flip the polarity of the subs 180 degrees, adjust the delay/distance until you get a maximum suckout in the frequency response at the crossover point, then flip the polarity back and enjoy.
post #1789 of 2086
Still figuring out Omnimic. I was led to believe that one of my tweeters rolled off above 10kHz by 15db at 20kHz. After much investigation, I put a towel over my desktop computer whose cooler has become noisy and the roll off was gone. Reinforces the rule to eliminate environmental noise when measuring. Too bad I've already ordered a replacement tweeter.

I got my new OmniMic and I am pleased with my results. This is a sweep from my sweet spot chair.

Not to be a killjoy, but are you using 1/6th smoothing? You might be able to further improve your listening experience by looking at 1/12th or 1/24th smoothing and see if there's an changes you can make to speaker/sub positioning that further smooth the curve, particularly around the crossover region between your mains and sub(s).

What are you testing?
post #1792 of 2086
^^^

Just sub response in that sweep. I really only have one spot for my dual subwoofers and while I am sure I could slightly improve the graph, it would take quite a bit of work. I might look into finding the absolute best spot sometime in the future but for now, It sounds good to me.

I wish settings such as smoothing were persistent and didn't require resetting each time Omnimic is started up.

Well, it does reset to 1/6 smoothing each time.  :-)

post #1795 of 2086
exactly what I meant.
post #1796 of 2086
Man, I really, really want to pull the trigger on this thing now so I can play with it over the long weekend, but I don't want to lose out on any Black Friday/Cyber Monday discounts...does PE.com price match or offer refunds if your item goes on sale after you buy?

Between this and my miniDSP, I should be able to customize my sub response quite well.
post #1797 of 2086
I am using software version 4.00

Now 4.02 is available?

Whats different?

Where can i get it from?

I have to remind myself as well. Unfortunately I'd lose the respect of the audiophiles on the Audyssey threads if I did anything less granular than 1/12th smoothing...and give up my status in the rabbit hole:).
post #1799 of 2086
has anyone tried to run the omnimic on an intel atom processor?

there is a windows 7 tablet pc at dell for $200 that looks like it might be a perfect companion for the omnimic if it is fast enough.

I run it on an Asus Netbook that uses an Atom processor and Windows XP. Seems to work ok.
