If all the measurements are inverted, their relative polarity is still captured. I'm no Dirac expert but I don't see how inverting all measurements would provide a different result for a room EQ scenario. FWIW it's quite common for amplifiers to invert the output, no one notices as long as...

There's an "invert" check box on the sound card preferences window.

REW is "compressing" the chart to maintain a specific aspect ratio, change IEC263 ratio to "as plotted".

No problem installing and running from my end on Linux, Manjaro flavour.

There's about 175ms timing offset when comparing the excfilt data to the EXC or LTI data. In any case, I don't think you need to keep EXCFILT, I don't think there' much to be gained from it that isn't already in the LTI response.

How? It's the only option you have with that equipment. Optimal configuration would be to get a XLR mic and plug it into your audio interface.

Carpets, rugs, cushy furniture, house plants, tapestries, curtains are all functional acoustic treatments without looking like acoustic treatments.

Try right clicking on the graph.

It's no problem, I can get what I need from the LTI file, I was just curious.

REW absolutely will show you the modelled impedance curve.

Make sure the acoustic reference is somewhat near the mic, of reasonable volume so it's well captured by the mic, and a driver with high frequency output, ie a tweeter. If there's significant reflections in the reference recording, REW may have a hard time picking out the fundamental impulse...

As another feature request, while I absolutely love the "measure with these filters" functionality within the EQ window, it's use in REW is quite cumbersome. It's very often that I need to take many measurements with a specific filter, and each time going through the process of selecting the...

Hello, For FSAF, I've noticed when using filters such as "measure with these filter" via the EQ window, that saving the excitation WAV file doesn't include the filtered result, it appears to simply be a copy of the original audio for the time length specified. Should this wav file not include...

I see no reason for you to do anything more than follow the REW measurement guide for VituixCAD. If you want to develop the digital filter within VituixCAD, maybe start with setting the Generic DSP system in the options (and select sample rate matching your DSP config) and confirming that filter...
