| What did I do wrong? I finally got around to trying REW again. Below are a couple graphs. The first is from the soundcard on my laptop being calibrated. The second is a room reading from 20hz to 100 hz. I had already done manual measurements and EQ corrections using the excel workbook for my RS meter so I'm assuming it should be flat down to 20hz. I was watching the meter and playing around with sine wave freqs in REW and none of the measurements match what the meter says. I did notice when calibrating the SPL meter in REW, I could only get 63db from the test tone even with my receiver volume at 0. Any suggestions?   | ||||

| Re: What did I do wrong? See how the second graph is the exact inverse of the meter calibration file? That's because you have an internal monitor loopback turned on as an option in the soundcard software. Find it and turn it off. Then you'll be OK... brucek | ||||
