Hey guys,
Here is my first test of Rew using standard laptop soundcard with the RS 4050 meter. I calibrated soundcard/spl meter and then i put pink noise in the system to -18db under speaker cal. but once i got my signals to ok and did my sweep it gave me a distortion alert. I read about this and it told me to lower my sweep volume which is default to -18dB. Well, I ended up having to lower this to -30dB before the distortion alert went away. So now, isnt my signal cal mest up if the -18dB calibration distorts? Because i had to record the sweep 12dB lower? Anyways some clearity on this would be great help. Here is the graph i did with the sweep calibrated to -18dB with a -30dB sweep.
