Hi all, I would like to ask if it is possible to add an A weight to the RTA chart for each frequency? I'm using this software for engineering measurements, so I'm not only concerned with the final SPL number with A-weighting, but I want to know how this weighting affects each frequency. On the picture you can see my mesurment with some peaks. I want to know how the A weighting change the curve and individual frequance. Thanks a lot.

One option would be to load an A-weighting EQ curve as a souncard calibration.
 
Thank you @dcibel and @John Mulcahy for your files (dcibel sent me it seperatly). It works pretty well. I sending picture with your calibration files and also without calibration, it is red curve.
