+1 on that. OmniMic is more expensive, but if REW becomes as easy to set up, and the HDMI support with ASIO4ALL addresses the 'pick your channel' aspect, it goes a long way toward overcoming the torture test that actually using has supposedly been to date. I hope PE is taking notes smile.gif

If the 5.1 DVD were released the OM would be back in the competition, at least for me.

I went to upgrade my version 3.1 software to the newer 4.0 and see that they want you to email the company giving them your serial number and date of purchase.

Has anyone else had to do this?

From their webpage:
Latest software version


The latest software version is: VERSION 4. Should you require an upgrade to your OmniMic software or need a replacement copy please contact us at: info@daytonaudio with subject line OmniMic Software Needed along with your name, serial number, and date of purchase.

I sure hope they are not going to want this for every software upgrade they put out.

Is anyone here using the OmniMic V2 with Spectrum Lab?

Sure looks like it.

So much for running test this weekend.

Did any one compare XTZ Pro II and Dayton? 

post #1900 of 2086

Any update on the DVD that is supposed to be available early this year?

post #1901 of 2086
Yes it is past development and debug, and is at the duplicators now . Shouldn't be too much longer.

Please - because as much as the OmniMic's easy to use and completely Plug and Play, the new REW compatabiilty with USB mics, selection of individual channels, and HDMI output is creating a tidal wave of Audyssey users adapting it as the standard for accessing room effects, recommended treatments, and post Audyssey calibrations.

The multichannel DVD will mean I don't have to start using REW, get a new mic and a SLM.

There is so much more to REW than just that though, Theresa. Consider the ability, for example, to take one measurement, of the full spectrum, and then to later be able to graph that single measurement as a FR chart, a waterfall, an ETC etc. And to be able to select any frequency range for the graphs that you wish, from the full spectrum available.  Also consider the ability to upload your measurement data file to a thread, where people with greater expertise could load that data file into REW and make an analysis of it for you. These are just a couple of things that have drawn me to the 'new' HDMI/USB mic version of REW. OmniMic has the great virtue of simplicity, but it comes at a price.

I was going to get a Rat Shack SLM today but it is -13 f. right now and I'm not going out today as this cold is neither good for my body or that of my vehicle.

You don't have to get a new mic as the omnimic will work with REW. It'll even now recognize the omnimic file correction extention.

Although I'm in favor of using the omnimic hardware and software, I have to wonder if the DVD is actually coming out. IF it's in the process of being pressed, then why don't they put the files on their website for us to download and start using it today?

I also just learned that the OM cal file is for the 0 degree mic orientation (mic pointing towards the center channel).  Since we're typically taking measurements in the 90 degree orientation (mic pointing up) for room measurements, this could be problematic for higher frequency REW measurements.  I suppose you might be able to send out the OM mic to generate additional cal files (if it's even worth it vs buying another USB mic)?

Most room correction isn't at higher frequencies, though.

It is possible to send the omnimic out for calibration files to be created at other orientations. Only problem is that you wind up paying within $20-$30 of buying the mic with calibration files. Then you figure in shipping from your location to the calibrators, and it's just not economically feasable. If you do go this route, mail it in the small flat rate box. It's $5.80. Just used that service yesterday and was surprised that you get 2 day shipping for up to 4 lbs at that price. Had to return some monoprice cables.

On a seperate point of interest, you can import your omnimic measurement into REW. I don't think you'll be able to do everything with it, but you can do some of the more common task which include determining correction filters for various subwoofer equalizers.

If you don't have an HDMI out laptop (or desktop), then your best hope is that the DVD actually gets released. As my earlier post indicated, I'd think that it'd be available for download if it existed at all. So I'm doubtful. Otherwise, start looking for an HDMI equipped laptop but wait until all the issues have been resolved with the 3rd party drivers. Seems that some can not implement the drivers due to hardware limitations. Might even be a good idea to find out which laptop someone is using who obvious has it working consistantly and order one of those.

+1...I have met Bill and he is a straight shooter.

I plan on using OM whenever I am working with my 5 subs/DCX2496 and room placement. I can start the CD and watch the changes as I move things around the room as well as play with settings in the DCX2496 and the Onkyo 818 AVR...it is way too easy and fast vs. individual full spectrum sweeps in REW.

I plan on purchasing a USB mic from CSL and getting back to working with the advanced features found in REW...I want to see how well I did with my room treatments. smile.gif
post #1913 of 2086
Why would you buy another mic? As JimP stated above, you can use the Omnimic with REW already.

James
post #1914 of 2086

I guess the main reason is if I am going to participate in the REW thread, they are taking measurements with the mic positioned upright (90 degrees) and the calc file with OM is calibrated at 0 degrees. It seems like there are differences in the HF range and the calc file might be off on the OM if I placed it at 90 degrees...

I would like to compare both mics and software to see if there is a difference...
post #1915 of 2086
Where did you read or find that the mic was calibrated at 0 degrees? Have you taken measurements at both 0 and 90 of your system and seen any difference (just wondering since I always took mine at the 90).

Once you are finished testing let us know what if any differences are that you find. Thanks.

I too have met Bill, spending a day listening to some music and talking shop. A great guy, gracious host, quite knowledgeable, and a true DIY'er.

So I don't understand those comments about the DVD release.

This is an aspect of OmniMic that I truly love. cool.gif

Hi James, I guess this is an assumption on my part based on the "speaker design" aspect of OM with respect to measuring at 0 degrees...maybe Bill will check in and let us all know. Since we didn't get any information on the calc file, I assumed they calibrated the OM in the 0 degree position. I always measure with the mic facing up to see what Audyssey has achieved in my room since the Audyssey mic is facing up. On the REW thread here at AVS, they are making a big deal about having calc files in 0, 45 & 90 degrees to get accurate results while measuring in the HF range.

I have taken measurements with OM at 0 & 90 degrees and didn't see any differences but I wasn't focusing on the HF range...I will post any differences.
post #1919 of 2086
Laugsbach,

Thanks for the reply. I must say I have not ever heard of this before “having calc files in 0, 45 & 90 degrees to get accurate results while measuring in the HF range.”, but then again I have not been reading too many audio threads lately. I will see if I can find it and see why people are doing it.

James, here is link to CSL that the folks are using in the REW thread:
