Hi,
      I recently got a UMIK 1. It will be used alongside REW to tune audio in automobile applications. However, while taking measurement inside the car with the engine and all equipment off i am getting the below reading which somehow  don't looks right to me. REW is installed on a Windows 10 PC, i have disabled the Intel Smart sound drivers for the PC to detect UMIK. Can some one shed light on this issue. The mic serial number is 709-1832  

That definitely isn't right. The most obvious thing to check is whether you have the UMIK-1 calibration file correctly selected in REW.

Calibration file was downloaded from the website, using the 90degree file out of the 2. Any settings I need to change in windows.

My point was about selecting the calibration file in REW...

This is the screenshot from REW.
 

^That looks sensible.

For what it's worth below is an old picture of a noise spectrum I measured with my UMIK-1. You may find you get this resolved more quickly on the REW forum rather than here but if you want someone from miniDSP to try to assist you should contact Support via the link at the top of the page.

 

Thanks.. i have asked on REW forum and is still waiting for answers.

Found that noise cancellation was ON in the HP audio controls. However, could not disable it so uninstalled it and tried. No change in measurements unfortunately.
 

Meanwhile i installed REW in an old PC, getting the same result prettymuch... can it be an issue with the caliberation file?
