Thank you :)

Minor annoyance - On ALL SPL chart, if there is an impedance measurement in my data set, using "align SPL" creates the following error: This forces me to de-select the impedance measurement(s) and try again. Would it not be more streamlined to avoid the error message and manual process and...

Interesting, DIM30 appears to come from IEC 60268-3 spec. https://www.audioprecision.com/news/dim-30-and-dim-100-measurements-per-iec-60268-3-with-ap2700

I think I wouldn't be surprised that a little micro-monitor with 3.5" driver struggles will bass, even at a relatively low volume. Potentially the little passive radiators are reaching their limits as well. Most/all drivers produce distortion (especially intermodulation) from bass, even high end...

Ok, I found "DIM" in the ARTA manual, but still don't know what the D stands for. I don't think REW's generator will do a square+sine multitone.

DIM? In REW you can measure inter-modulation using the signal generator and RTA. The signal generator is quite powerful to define a multitone test of your choosing. In the RTA window, I recommend selecting "show distortion" and save the measurement, on REW main window, select the distortion...

Reposting my request here as it may have been lost in the ongoing confusion of the FSAF thread. For FSAF, currently to evaluate the spectrum of the recorded residual audio, it requires a few steps of going to Distortion tab -> controls -> load FSAF residual as a new measurement, then go to...

SPL tab shows the frequency response of the measured device. Distortion tab shows the spectrum of the recorded audio. You can use many different stimulus audio and have very different distortion spectrum. But measurement frequency response on SPL tab will be the same. In your above screenshot...

Result is total distortion and noise, everything that is not in the original audio. When there is nothing in the original audio, measured result is only noise. Repeating advice already provided:

The other thing to note is that REW distortion tab for FSAF shows very limited information. It's just the spectrum of the entire recording. For a detailed analysis, open the distortion controls, listen to the residual, as well as select "load FSAF residual", then go to the spectrogram tab to...

Is the "timing markers" option enabled? I believe this is intended to correct for the unpredictable delays in windows audio. In any case, EXCL or ASIO is what I'd recommend. It looks like user### is using some drum samples as test stimulus, which have a fair bit of "Dead air" and don't excite...

Right click on the measurement itself in the left pane and adjust the offset there. Right clicking on the graph will adjust level for everything actively shown on the graph.

Perfect, thank you.

I am looking for an option for large thumbnails on the ALL SPL view. For my use, I use "show measurement level on thumbnails" for comparing same measurements at different levels without having to name each measurement individually. This information is absent on the ALL SPL view which only shows...
