REW SPL Meter Calibration against C- or A-Weighted SPL Meter

[Chris Lineau]

Dear John,

I want to use the REW SPL Meter. For the calibration I was just wondering whether I should set my external hardware SPL-Meter to C- or A weighting. When I hit on calibrate in the REW SPL-meter, the REW SPL-meter always jumps back to C-weighting, no matter if I have set A-weighting on the REW SPL-meter before. Can you tell me which weighting I should use on my external SPL-meter for the calibration? I didn't find anything in the online manual pages.

Kind regards,

Chris

I’m sure John will weigh in on the REW issue, but for audio purposes, external meters are typically used with C-weighting.

Yup, C weighting.
