Hello,
I'm new to the group, just getting REW set-up on my laptop, am going to use the old model RS sound meter, Model 33-2050.
I'm mostly concerned with the lower frequencies, out of curiosity I opened the cal file using wordpad, I saw the value for 20hz was - 17.04, 16hz was - 20.63, both which sounded high. I also downloaded and opened the cal file for the newer model, 30-2055, it showed - 9.05 at 20hz and -12.66 at 16hz, which sounded closer for the newer analog meter.
All the values for the newer model showed less extreme then the 33-2050. After reading several articles on the accuracy of the older model verses the newer models I expected the opposite ! Am I in error what these cal files mean ?
Looking foward to using REW and I'm sure I'll have questions in the future. Thanks to any help/explanation you can give me.
Dave

Neither meter is really oriented toward good low frequency performance, and not particularly great above 3kHz either. Cal files will show differences for every meter/microphone. Typically the higher the boost, the further into the devices noise floor the signal is.
