Thank you sdurani for that link. Do you or any others on this thread feel that the REW calibration program would be better than my Audysey program which came with my Onkyo TX-SR 876 AVR? I know absolutely nothing about the REW program but the Audysey program seems to work pretty good. Your replies and sharing of your knowledge would be greatly appreciated. Thank you and Happy New Year to everyone.

REW is not a calibration program... it will analyze your system in several different respects, but does no equalization itself. It can help you with suggestions on what to equalize. It will let you see what Audyssey is doing to your system. I think most of us here use it more to help determine what we need to equalize our subwoofer response, but we also like to see the overall response of our systems.

Happy New Year!

REW actually doesn't do what the Audysey, YPAO etc does.
REW measures what these have done to the sound/room, in your system Audysey, with more accuracy.

REW will help to fine tune the effects your system with bass traps, EQ etc.

Hope this helps a bit

I'm curious to know exactly what John has done to help install/use this mic as a PNP option in the new REW.

The reason I ask is that although this mic is a good option at a good price, it comes directly from Hong Kong and isn't truly individually calibrated like for instance a UMM-6 USB Mic would be that you can purchase from Herb at CSL, who is also a great forum contributor, and a US Based business, for about the same price.

I don't have either mic yet and I've been helping some folks get on the REW bandwagon over at AVS and there have a been a lot of questions and concerns from folks worrying about setting REW up for the first time.

While I know it's simple and have been working with it for a few years now, I do know it would be much better/easier if John could/would offer the same support for the UMM-6 Mic as he does for this MiniDSP mic as I feel more comfortable in recommending the UMM-6 to folks for the reasons mentioned above, mostly due to the personalized calibration though.

I'm not a huge poster over here and if there is a thread this would be more appropriately posted in, I'll be more than happy to move it or ask again.

Can someone explain the difference in setting up the UMM-6 mic vs setting up the MiniDSP mic in REW and can someone who is in contact with John ask if he can add support for the UMM-6 Mic just as he has the MiniDSP or direct me to the proper forum in which to ask this question?

Thanks so much,

--J

Thanks everyone for your replies and answers, they really helped. Is the mic that I need to purchase the only thing I need to buy in order to get started with REW? Thank you.

These forums are very helpful with setup etc.

Agree


I thought the UMIK was individually calibrated?

Maybe post in the UMM-6 thread.

What i understand is that there wouldn't be any difference. Only thing that comes to mind is the SPL, which comes with the UMIK calibration file, not sure if it comes with the UMM-6.

The only extra you will need is a RCA from your laptop to the receiver.

I use the Omnimic and this the only extra i needed.

So, as I understand it, when taking measurements, the mic should be pointed towards the speaker & not the ceiling, while using the supplied calibration file.

I just got my UMIK today. I can't find a calibration file anywhere or instructions on where to download it. Can anyone point me in the right place?

Sorry if this has been covered but can this mic be used as an SPL meter to set speaker/subwoofer levels using AVR test tones?

Yes, with REW's SPL meter - the cal file includes the sensitivity info REW needs to translate the readings into SPL figures.

I wonder if there is a backlog in orders. I ordered on Jan 2 and website has not updated from "confirmed". I have not received an email confirming shipment and the calibration file. Anyone else experiencing a delay?

Would this microphone be suitable to use with a DRC program such as Audiolense? I have checked with Dirac and thye have run some tests with one which they have had in their office but no conclusion yet as they have had inconsistent results on 2 computers they have tried it. One worked and the other they had an issue with. They are preparing for CES but will get back to me after the show.

I've always wanted to get into REW but never could. I had an old RS meter but I could never get it to work properly. This was several years back.

So this new mic ... basically you just plug it into your notebook/PC, and two cables to your receiver, and that's that? I really think I should move on this as it gives me another opportunity to be able to measure using REW which I've always wanted to do but without requiring additional gear .. like an ext soundcard and phantom power.

Hi Everyone,

I am having some issues with my UMIK-1 and hope some of you might have some helpful advice.

1st Problem:
On both Mac (REW v5) and Windows (latest REW beta), the SPL readings appear to be way off. In my quiet apartment, the UMIK reports about 65-75 dBSPL, C-weighted. I have a standalone SPL meter which reads about 10-15 dB below this. I would tend to trust the calibration on the UMIK over my cheap SPL meter, but I think the UMIK reading is way to high for just the ambient noise level. These measurements were taken with the UMIK cal file loaded in to REW in both Mac and Windows.

2nd Problem:
When using the UMIK and REW on Mac, REW reports that the UMIK is clipping when taking measurements. This happens even when using my Macbook speakers for output, so I'm sure the sound pressure is not actually exceeding the range of the UMIK. I tried adjusting the UMIK level in the Mac OS MIDI Setup, but it did not appear to have any effect on the results. I am using a 128k sample length for these measurements.

Has anybody seen these issues? Any ideas?

Thanks,
Mike

I am having an issue with my UMIK-1 as well, the tracking # says it is pending a customs inspection since 1-3-2012 :rant:

We are sorry to let you know your order is delayed because the
product (UMik-1) is currently out of stock.

We will ship out your order as soon as we receive the next batch of UMik-1.

We apologize for the delay.
