The measurement process was relatively straightforward and quick (actually the quickest of these three), and the resulting responses seem in line with what I was getting with REW. I don't like the fact that you can't edit (or even see) the target curve in the plugin (Processor component), and due to issue with loading saved projects it can be tricky to edit saved curves. Usability and UI is very nice in general - though I was having some issues with logging-in to the user account on the Processor component (VST plugin) and was also getting some errors when loading saved projects. Here's some of my quick thoughts on each one of them: Measurements were done with a Cross-Spectrum Labs calibrated Dayton EMM-6 measurement microphone and RME Babyface Silver edition soundcard. Sonarworks Reference 4 Studio edition - €299 with micĪll of them offer free trial versions, which is what I used to test them out and compare.IK Multimedia ARC System 3 - Price: €178.49 software only (on sale right now) or €304.99 mic included Crossgrade price: €99.99 SW only or €182.99 with mic ( EDIT: updated ARC3 pricing info, thanks for info).Dirac Live 3 for Studio - Price: $349 SW only.As you can see, we get a bit of bloom under ~200Hz, which should be right around the Schroeder frequency of this room. Some of my in-room measurements are available already in this post, and here are the quasi-anechoic measurements of our pair of speakers. Lately I was playing a bit with digital room correction (DRC) SW to see if I can tame the bass in our living room with a pair of Revel M16 (no subs) so I thought it could be useful to share my findings.
