Mic sensitivity .cal file

[oliver]

Dear John,
I am on Mac OSX, latest REW build.
I do have a sound card with 8 inputs with each a different microphones/sensors.
I would like to make a sensitivity cal file for each input, in order to not repeat the calibration process every time I switch input.
I do not want to load a SPL Meter Calibration data, but just a file were only the sensitivity is indicated.
I tried to make a .cal file with only the "Sensitivity" line, but REW shows an error window:

Probably I am doing something wrong, is there a way to load a .cal file with only the sensitivity value?

Another question,
is there any way to rename the inputs with reference to what is connected to them?

Thank you.
Oliver.

Just add a couple of frequency values in the file with 0 as the correction. There isn't a way to relabel the inputs, sorry.
