Simplified REW SPL Meter Calibration for XLR mic.

Attached is a pdf of a simple method to calibrate the REW SPL meter when using a XLR mic and external audio interface (analog IOs). I think this general thought process can be applied to most any common interfaces used with REW. It only requires a suitable loopback cable.
[This method has not been tested with various interfaces so it is possible that one with a much higher max output level may require using a modified version of this method; one that uses less than full output level?]

The absolute accuracy of the method is not likely to be any better than using an SLM or multi-meter. Instead it provides a quick easy way to get a highly repeatable REW SPL cal level from calibration to calibration using only a simple loopback cable. The input level and thus the resulting headroom can also be easily changed without any impact to the REW SPL meter level.
