Hi everyone, May I get some advice here? I have tried to flatten the SPL response of my room over the whole spectrum. My strategy has been: using MSO to handle the lower part of the spectrum and then using REW EQ filters for the rest. For the low end, I optimize with MSO until 300 Hz and I...

Hi, I would like to make a calibration file of my microphone (an USB mic, not UMIK-1). I wonder what kind of information needs to be provided in the calibration file in order to make REW treat the microphone as a SPL-calibrated one ? I tried the calibration file of UMIK-1, but REW doesn't...

Hello Beginner question on SPL reading calibration referenced in the help file section 'Calibrating the SPL Reading'. Where should I position my SPL meter? Should it be at the same position as the position of the measurement mic (which is not a USB mic)? Thanks!

Hi There, i have recently connected a UMIK-1 mic to REW with a particular interest in the SPL module. when i am measuring sound levels of the ~90dBa range (~100-105dBC) i start getting the "Over" warning appear. i also notice that the levels meters are showing very close to 0 (i.e peaking). is...

Dear REW community, A hopefully simple question! Are frequency sweeps and accurate way to match the level of left/right stereo speakers? To explain: I usually calibrate my speaker levels using pink noise and the SPL meter in REW (together with a handheld SPL meter as a double-check), but I...

Hi all, Sorry if this is a stupid/basic question but I'm looking for a tool to allow me to take measurements of a device (electric motor) and the measurements of a room and then compare both sets of data to generate a spectrograph of JUST the electric motor IE remove the noise of the room to...

Hi folks, I’m a REW newbie, having arrived here from starting out with Fuzzmeasure (which I also like). So far I’m really enjoying some the extra functionality offered by REW. However, I have a newbie question that I’m struggling to find an answer for, having searched this forum and the REW...
