Note: Windows 8 Users

Windows 8 has a USB recording bug. To get around this issue and use the OmniMic on a machine using Windows 8, please perform the following:

Find the OmniMic icon, Start Menu entries, etc., that you use to start the OmniMic software. Instead of left-clicking the icon, right-click and then left-click on the "Properties" menu item. A "Properties" window should open. Select the compatibility tab and find a checkbox labeled "Run this program in compatibility mode for:" There is a drop-down box just below the checkbox, set that to "Windows XP (Service Pack 3)". Then put a check in the checkbox and click "Ok" to close the properties windows.

Now when you start OmniMic using that icon (or menu item), it will run in the XP mode that avoids the Windows 8 USB recording bug.

Calibrate Your OmniMic V2 Instantly

A unique serialized calibration .txt file will be available for your OmniMic V2. Once you receive your microphone, click Calibrate OmniMic V2 where you will be prompted to enter the serial number found on the base of your calibrated OmniMic V2. After entering the serial number, your unique calibration .txt file will be available for you to download.

Dayton Audio OmniMic V2 Precision Measurement System is rated 4.7647 out of 5 by 17.
Rated 5 out of 5 by from exceptional packageI've used many acoustical measurement systems over the years and found the OmniMic V2 a very solid package. Its very user friendly and accurate both expert and novice will be comfortable operating this measuring system. I compared it to systems that far more costly and found it just as accurate if not more simple to run. Hats off to both Dayton Audio and the folks at Liberty instruments for creating this great acoustical measurement package.

Rated 4 out of 5 by from Easy to use.Fantastic tool, very easy to use. A little bit expensiv, but is mandatory in the toolbox.

Rated 3 out of 5 by from Seems great, but no decent tutorialI purchased the system to improve my theater. When I began trying to use it, I realized that using it is kind of left to 'try this or try that' and it seems I'm not getting anywhere. I am getting measurements but having a hard time interpreting the results. Do I need to run the entire test CD for this or just certain tracks for that? How do we average readings and then extract the corrections needed to acquire the EQ desired? After reading the entire Help manual for the third time, I still am foggy on how things are done. I yet have a million questions. A tutorial for dummies would be appreciated so dummies also would be permitted to acquire better audiophile listening.

Rated 5 out of 5 by from Very easy to set upSo far I just started using it , looks like a great asset for measuring speakers without breaking the bank! so far so good , the mic cable and connector could be a of better quality the cable is quite stiff and the connector should be a locking type .but overall its performance its good all around .

Rated 5 out of 5 by from This is a good piece of deviceI'm starting working in this subject of testing sound and this is quite simple to use and quite accurate. Sw is quite good and easy to use.

Rated 5 out of 5 by from So far, very simple to useI believe this is simpler than I expected. I tried using an EMM-6 mic and ARTA, but couldn't get it to work. The OmniMic system is easier than I expected. Install the software (easy), load the mic calibration file (easy), and plug in the mic (super-easy). I ran some measurements on a speaker I was listening to at the time and it worked first time. I'm not good at anything that has more than two or three steps in the instructions. I;ve been trying to get my head wrapped around speaker design for more than 5 years. If the Omni-Mic is easy for me, it should be easy for anyone. If you're on the fence about getting one, don't let the fear of complexity stop you. It really is very easy to use,

Dayton Audio OmniMic V2 Precision Measurement System

Does this system let you record MLS or sine sweeps, derive the impulse response of the speaker, and then export the impulse response (for example, as a .wav file)?

Asked by: SoundGuyInc

Will this work on a MAC?

Asked by: SHCEO
Unfortunately no, this is not Mac compatible.

Does this give you recommended EQ settings?

Asked by: Mcallister
This will not tell you specifically what to EQ per se, but it will show you problem areas in the frequency response in the way of peaks or nulls which will allow you to EQ those frequencies to your liking.

Are replacement microphones available?

Asked by: AMF2

Will this help me time align my speaker system? I am using separate low and hi frequency drivers with dedicated amplifiers and electronic time delay crossover.

Asked by: Benzov12
Yes, OmniMic provides several features to help with this. You can use the impulse plot in the Frequency Response section to make sure that all the impulses line up, and you can further examine the decay characteristics of your system with the "waterfall" and "wavelet spectrogram" plots.

Will this work with my Samsung Galaxy Tab S ? Thanks

Asked by: cyberboy
You need a Windows PC (or a Mac running Windows) to use the OmniMic software and obtain the full "plug and play" experience. However, the OmniMic hardware will provide audio input via any USB connection (similar to a USB sound card but with only one channel of input), and some tablets and smartphones can accept audio input from the OmniMic hardware, but you will need to use third-party measurement software that can load the OmniMic calibration file in order to receive accurate results when performing acoustic analysis. We have not tested tablets and smartphones for proper operation with the OmniMic (since that is not its intended usage), so compatibility depends on your handset or tablet hardware, your OS, and any required accessories that provide USB connectivity, and we cannot guarantee compatibility with a particular handset, tablet, or accessory.
