Hi, I would like to make a calibration file of my microphone (an USB mic, not UMIK-1). I wonder what kind of information needs to be provided in the calibration file in order to make REW treat the microphone as a SPL-calibrated one ? I tried the calibration file of UMIK-1, but REW doesn't...

Hi, I would like to use UMIK-1 to measure SPL with my Python code, but I can not find the sensitivity of UMIK-1, nor in its datasheet of its calibration file. In its calibration file there is one line saying "Sens Factor =-0.667dB", but it doesn't make sense to me. I wonder how REW calculates...
