Microphone ID
Sonarworks XREF 20 measurement microphones are individually calibrated to exhibit neutral frequency response during the speaker measurement process. This data is available in a form of a microphone calibration profile and can be accessed via the Microphone ID number. Each XREF 20 mic has its own unique Microphone ID and it can be found imprinted on the microphone unit, as shown in the picture below.
Loading the microphone calibration profile in Reference 4 Measure
The mic calibration profile can be loaded straight into the Reference 4 Measure app during the Hardware Setup stage of the speaker measurement process. To load the mic calibration profile, simply enter your Microphone ID as shown in the picture below. Note that this functionality requires an active internet connection.
Downloading the microphone calibration files
If you need to download the actual calibration files for any reason (using an offline computer, using the XREF 20 mic with third-party software, storing them for backup purposes, etc.), they are also available to download on our downloads page here. Simply enter your Microphone ID as shown in the image below - this will download a .zip package consisting of two files:
- Microphone calibration file for 30° off-axis measurements in .swmic format (Sonarworks software native format) to be used with Sonarworks Reference 4 Measure app.
- Microphone calibration file for 0° on-axis measurements in .txt format for third-party use.
Using the .swmic file to load the microphone calibration profile in Reference 4 Measure on an offline computer
- Download the microphone calibration files as described in the previous paragraph (see above).
- Extract the files from the downloaded .zip package. Most computer operating systems feature free built-in utilities for compressing/extracting ZIP files, but you can always use free software like 7zip if having any issues.
- Click on I'm Using an Offline Computer when presented with the "No internet connection" dialog during the Hardware Setup stage in the Measure app (the dialog will appear automatically if there is no internet connection)
- Click on Browse... to load the calibration file
- Navigate to the .swmic file (extracted from the .zip download) select it. Press Open to load the file
Is it possible to use the XREF Profile in other measurement apps in order to make further use of the the mic?
Yes! This is why we provide the 0degree claibration .txt file which you can upload to other software!
Hi!
I would like to measure my room with XREF 20 on Room EQ Wizard.
I would need a 90 degree calibration file for a flatter response of the whole room.
Is it true there are no 90 degree calibration files for the Sonarworks mic?
Hi Chris, download link refers to trial version of Reference 4. Where can I download the XREF 20 calibration profile exactly? I'll use it with Room EQ Wizard, but I can't find the file or is it located in Reference 4 folder on local hard disk somewhere after entering serial number of the mic?
Thanks a lot!
Hi Guys!
We don't have a 90° file available, but we might introduce it at some point. The mic files can be downloaded here.
Hi, download works on PC maybe an issue with smartphone. Thanks a lot!!!
I've just checked it on the latest iOS and the download does work for me. Are you running Android, which version? What is the browser you're using?
Hi!
I can't find the dowanload link of mic profile.The page I opened is different from you sent on June.However, I used Android and IOS smart phone. Where can I download profile now？
Hey!
I apologize for the inconvenience!
You can still download the microphone calibration profile, but it has to be done using a computer or employing the desktop mode in your mobile browser.
This is so because Systemwide cannot be installed on mobile devices and there are not too many mobile applications for Measurement microphone use.
Why does the file not contain phase values?
Hey Raphael,
This is due to the fact that the phase response of the microphones is quite linear. The only distortions that might be present are beyond the range of human hearing.
I must note that the phase response of the microphone is not as relevant in when measuring your setup with the Reference software as we do not correct the phase discrepancies of the room, but generally only frequency response.
Like mirock616 I'm also looking for a 90º correction profile. Is there any way to get this?
Hey Bob,
I am sorry to disappoint you, but 90 degree calibration profiles are not available for XREF20 microphones.
In my case, I was looking for the 90 degrees calibration profile to use the mic with "Room EQ" (REW Software) in order to research acoustic treatment. Is it possible with the 0 degree calibration file?
Hi Shawn,
0° degree file is available as described above but 90° is not available. It could actually be possible to add 90° files at some point down the road (also for the existing mics that are already distributed), but not in the near future, I'm afraid.
