I've run RoomFit in two rooms now and it's a clear improvement in sound quality over using Room Correction for me.
I've played with it a bit and since documentation is light on this currently thought it might be useful to post how I have used it.
Here's my setup for ref:
Office: Q Acoustic M20's, Q Acoustic 3060S Sub, WiiM Ultra. Simple signal path here.
Lounge: Q Acoustic Concept 30s, Q Acoustic Q Sub 80, WiiM Ultra, Audiolab 6000A. Vinyl is with a Pro-Ject Debut Evo 2 and Pro-Ject Phono Box S2 Ultra.
VINYL : Pro-Ject Debut EVO 2 (turntable) → Pro-Ject Phono Box S2 Ultra → WiiM Ultra (line in)
STREAMING : Roon/Qobuz → WiiM Ultra
FROM WIIM ULTRA (post RC / bass management)
→ Sub Out → Q Acoustics Q Sub 80
→ RCA Line Out → Audiolab 6000A → Q Acoustics Concept 30
I use the UMIK-1 mic for RoomFit - I think this mic is a very good investment for this.
In the office I connected the UMIK-1 to my Mac via USB-C and in the lounge I connected it to my iPhone 16 Pro via USB-C. I ran the RoomFit on the Mac in the Office and on iPhone in the lounge.
In both rooms I used the same settings for RoomFit:
Target Curve: Harmen
Freq: 20.0 to 4000Hz (to include the sub frequencies because I have subwoofer calibration on)
Max Gain: 10db, Min Gain: -10db
Max Q: 10
Cut-Only mode : off (not sure when I would use this unless there was a particular issue with room resonance to remove?)
External Microphone: UMIK-1 (On the Mac I had to select this in Sound Settings > Input first)
External Mic Calibration : I use the 90Deg file for the Mic (you download this from a code when you buy the mic). This is the one that expects the mic pointing upwards.
Subwoofer Calibration: on
Moving Mic Measurement (beta): off (I may try this in the future though, just trying to understand how you actually use it - seems to be more valuable if you want to fix gaps in the acoustics or optimise for more than one listening position - though I am guessing on that)
Advance Settings : Smoothing: 1/6 Octave (not sure why!)
Multiple Measurements (beta): On (takes 3 readings instead of one which makes sense to me)
Not sure if these are optimised but they have worked well for me in both rooms.
I hold the mic pointing up where my head would be in my listening position and run RoomFit. I made sure the room was nice and quiet through the whole procedure. I chose the option to measure left and right, which in hindsight might mean I should have used the other calibration file for the mic and pointed it at the speaker I was testing - oh well I will need to try that later!
Once run I named the profile appropriately and turned off EQ, so just RoomFit is on. My understanding of EQ vs RoomFit, is that RoomFit adjust for your room acoustics and then you can vary EQ on top of that for different music or input/outputs. For me so far I have just left EQ off, but I could see a situation where I may create an EQ for certain music types for example and have it as a preset.
Anyway hope that is helpful. And if anyone has any suggestions or better explanations I would be happy to hear them.
