Hi all.
I have 2 mics:
- Calibated UMIK-1
- Not Calibrated UMC8000
What is the right way to create calibration file for UMC8000:

You can do a substitution calibration, making a measurement with each mic in turn from exactly the same position (usually best close to a source) and then using the All SPL trace arithmetic A/B to calculate the ratio of the responses. Probably best using magnitude-only data for the ratio, which you can make from the measurements by selecting each in turn (with no other measurement selected) and using the "Average the responses" button which will produce a magnitude-only copy. The UMIK-1 measurement needs to use the UMIK-1 cal file. Levels should be manually aligned to match at 1 kHz.
