I bought a new USB soundcard, the Focusrite Scarlett 8i6. One of the first things I did with it was to run REW's soundcard calibration. I have REW v5.20.4.
I followed the instructions shown in the help section in the bottom part of Preferences > Soundcard. Connected the output directly to the input, set the output level to -12dB as remommended, adjusted the input channel's volume until it matched the output bargraph (+/- 0.2dB), then proceded to the measurement panel. This is what it showed:
Except for the very minor glitches at 50Hz and multiples thereof, I think this looks decent. Do you agree? Please do write if you don't, and tell me why.
Subsequently, I could then make the cal file.
I don't remember why, but for some reason I then did a regular measurement (not calibration) with the exact same physical setup. Same wiring, same level settings on out- and input.
This is what I got:
I do not understand why this curve is so very different. Shouldn't it be equally linear???
