It's a bit noisy but averaging multiple sweeps helps a lot (averaging is common in acoustical measurements), as does running the sweeps as close to full-scale (0dBFS) as possible. One thing I love about REW is the real-time readout showing the noise floor before the measurement starts. The 10k...

This is great! Thank you John! One issue I noticed is that when I toggle the 'Use harmonic frequency as ref' check box on the Overlays Distortion plot it didn't switch back and forth, I realized changing one distortion plot (standard or overlays) changes both (which makes sense). If I go to...

I may be late to the game, but couldn't find anything posted about DATSv3 when searching the REW forum. I've been using my DATSv3 with REW to measure impedance and Thiele-Small parameters on my Mac and posted a how-to guide on diyaudio a couple of years ago (see attachment). It's become even...

Hi, Is it possible to plot THD in percentage on a linear y-scale? So far I can only plot percentage in a log scale. Also is it possible to plot two different THD plots simultaneously? I often find it useful to plot two THD plots on a linear scale when comparing different speaker implementations...
