I did the calibration and saved it but as it turns out i need to calibrate each time i do a alignment .
I can put in the sensitivity but if i verify with a calibrator (piston@94db) it doesn't match al the time . It's always a bit of .
If i punch in the numbers on sim3 and then verify spl read out on the mic it's off and the same within smaart compared to the piston@94dB .
The smaart i/o's are great . First calibrate and after that you joggle the gain settings all you want . The spl read out will still be valid .

In the help file it says as you already found :
"The Microphone selector is normally disabled unless you are using an input device with known electrical sensitivity, in which case you will be able to store and recall sensitivity values for named microphones that allow you to essentially calibrate Smaart to SPL (or some other reference) without a sound level calibrator."
I suspect you'll need to use the smaart i/o because i can put in a voltage/p.
Maybe ask the people from rational
