The total power utility will display the total RMS power level for the entire spectrum and is equal to the total power bar on the right side of the spectrum plot. The weighting (Flat, A, B or C) used for this utility is set under the Scaling options dialog box. This is equivalent to the readings on a Sound Level Meter with calibrated to units of SPL.
This utility window can be resized as required by the user and its contents will update anytime a new spectrum is computed. The window will contain the channel index and name; the channel name can be modified in the Calibration Settings.
Right clicking on the utility window will allow you to copy the contents to the clipboard.
