    REW Forum
    In REW I'm wondering if there is a way to add a calibration factor to the Generator basically in the same way you do for the SPL Meter.

Generally, the calculation of THD agrees between both but the THD+N as calculated by REW5 is always much higher (more than a factor of 2). Is...
