I have been using REW for a few years now and I am embassed to ask this but I can't figure this out. I know is a simple solution but..
What is happening is I left my SPL meter on and drained the battery so I replaced it with a new one.
When I went to do a new measurement I did the calibration to 75db first but when I did a sweep the volume was so loud well about the 75db set during calibration. The clipping message came up and the graph was in the high 80's.
I leveled the sound card again and have it set according to the program -18 output, -12db left and right. callibrates for main speakers. I'm using speaker out and line-in.
It's connected to my pre amp and the volume is set there to read 75 db on the radio shack meter.

so what going wrong Help!

I did the check level and I say's the volume is OK. That volume is OK and reads 75 db on my digital radio shack meter. Them I go to do a measurement the volume in much louder then when I calibrate it or do a check level. I have to lower the volume on my PC from when I set the calibation so it's not so loud and displays it in the correct range.

I have it set for the 80 db range. I will try again tonight to see if I can figure this out.

OK I said I was missing something small and stupid. I had the loudness button cheched on the soundcard settings. I unchecked it, recalibrated and I'm back in busimess .

Thanks for all the help.
