Hi,
I'd suggest starting with the 'Wiim Support' menu at the top of this site and searching for roomfit or room correction.

(I find googling "wiim faq <subject>" often brings up the relevant WiiM support pages, inter alia
)Have a look at this FAQ article as well for some practical setup tips.
Some additional notes:
- Speaker/sub placement is really critical, and needs to be optimized first for RoomFit to work well! This IMHO cannot be overstated. I provided some placement advice and explanations previously in this post.
- I'd always recommend to use "Individual Channel RoomFit" instead of "Stereo RoomFit" when the option is presented.
- RoomFit "No-Boost Mode" was released recently and I'd advise to enable that. In this mode good values to start are Min Gain: -12dB, Max Gain: +6dB, Max Q: 10.
If you have a UMIK-1 I'd definitely use that, regardless of the phone you use with it.
Just note that some phones were reported to underrepresent bass even with external mics connected (see this example). I don't believe there's any definitive list of devices that have this issue, though.
Sorry, I don't know. Perhaps try searching in the forum, other members might have experience.
IMHO you can get very comparable results with RoomFit and REW, see here for an example.

Hi, here are some screenshots taken during the measurements.
I first performed the measurements with the Umik-1 microphone using an iPhone 15 Pro Max. I didn't perform them with an iPhone 16 because it's my daughter's; it's like asking for the key to the safe.
1. RoomFit Profile 1, individual channels from 30 Hz to 500 Hz, then
2. RoomFit Profile 2, stereo from 500 Hz to 20,000 Hz.
I saved RoomFit Profile 1 and then manually entered the Profile 2 data into the EQ as recommended.

2. RoomFit Profile 2, stereo from 500 Hz to 20,000 Hz.
I saved RoomFit Profile 1 and then manually entered the Profile 2 data into the EQ as recommended.
First, I see you followed my suggestion from this post to create two RoomFit profiles for the respective parts of the spectrum. Note that later here I provided a bit more detailed RoomFit parameter suggestions.
However, as I mentioned in that other thread as well, this approach should really not be the first thing to try. RoomFit (and any room correction really) is best suited to handle correction at low frequencies only.
Of course if you're already happy that is great and you should just listen to music and enjoy!
In case you'd like to further optimize I'd suggest to first check the basics - especially speaker/sub placement.
Important information for this would be:
- Dimensions of your room?
- Do you use a subwoofer and how is the crossover configured?
- What loudspeaker model are you using? Can you find a generic EQ profile for them on spinorama.org?
- When siting at the listening position how far is your head from each loudspeaker and sub?
- How are the loudspeakers and sub positioned in your room, including distances from each wall/ceiling/floor (referenced to center or woofer/driver)? It might be easiest to draw a simplified floorplan with dimensions and distances.
- Without a sub: Push the loudspeakers all the way to the wall behind them. Leave 5cm gap if the speakers are back-ported.
- With a sub: Put the sub it in the room corner for maximum bass, cross at 80Hz, and keep loudspeakers >1,1m from the wall behind them. If you can't bring loudspeakers that far out into the room, push them all the way back to the wall behind them (again 5cm gap is speakers are back-ported).
A more complete and detailed explanation can be found in this post.
Yes, I was inspired by your post.
I have a vintage two-channel system, without a subwoofer.
The room is about 60 square meters. When I'm alone, I position the armchair further forward, about 400 cm from the speakers. That's where the sound is best. But when my wife is there, I have to move the armchair further away from the speakers, 116 cm from the rear wall; unfortunately, that position increases the bass. That's why I decided to apply room correction.
The speakers are 50 cm from the rear wall; if I move them closer, the bass increases.
In a family environment, you have to compromise.
I'll do another measurement as you suggested.
One last question: once I've run RoomFit on the individual channels, do I need to deactivate RoomFit to perform the second measurement in stereo?
How do you like the measurements?
Thanks

Note that this bass increase would actually be a plus when using RoomFit, as you'd have more level to work with which might give you a smoother bass response in the end. RoomFit should be able to knock down any excess bass easily so that isn't an issue, but filling in holes in the bass is much more challenging.
No need to manually deactivate the previous profile, RoomFit will automatically disable the previous profile when you re-run the RoomFit measurement.
But as I said, I wouldn't really recommend applying RoomFit correction at higher frequencies, unless there's really no other alternative.
Do you have some specific problem with the way your speakers sound without correction (without taking bass resonances into account)?
If you know the make and model of the speakers perhaps we can find some anechoic measurements and try to determine if loudspeaker correction is required at all.
It looks like your speakers are able to reproduce quite low bass in your room - this is great. The fact that apart from the two prominent resonances (at ~55Hz and ~100Hz), most of your response is contained within about 5dB range even without RoomFit also seems quite good to me.
However, there are some minor dips/nulls in the bass response that could probably be further improved by optimizing placement of the speakers.
For the frequencies above 300Hz I can't really make any judgement on the response without knowing how the speaker behaves anechoically.
My speakers aren't listed on the Spinorsma website. I have Grundig Box 2500 Audio Professionals.
If I listen with my listening position 400 cm from the speakers and 200 cm from the rear wall behind my ears, I don't need any room correction. It's from that position that I listen to CDs and vinyl records without any problems.
I'm skeptical about the effectiveness of the response calculated by Wiim with an iPhone. I tested it with ReW some time ago and didn't notice any bass deficiencies below 50 Hz.

OK, that suggests that you enjoy how these speakers sound without any EQ.
Accordingly I'd advise not to use RoomFit at higher frequencies at all - to avoid changing the basic sound signature of your loudspeakers.
So I'd personally suggest to completely disable the "Stereo" EQ profile ("Profile 2").
The correction is not calculated by the phone, this part of the process is done on WiiM servers, at least as far as I understand.
The phone is just used to measure the response and pass it to the servers for correction filter calculation, and then to push the calculated correction filters back to the WiiM device.
If you use a calibrated UMIK-1 connected to your phone then the response you measure should be quite reliable and basically equivalent to REW. I get very good matching between REW and RoomFit measurements with my UMIK-1 (with Samsung S23+ phone) - see this example.
For your second listening location (where you notice increased bass) I'd just use RoomFit to bring those bass resonances down. The following RoomFit setting should do just that:
- Individual Channel RoomFit, Smoothing: 1/12, Target: B&K, frequency: 30Hz-200Hz, No-Boost Mode: enabled, Min Gain: -12dB, Max Gain: +6dB, Max Q: 10
That's what I would try, anyway.
Good luck with your tests!

It's now possible to manually edit a RoomFit profile. That is nice but how do I check if the edit improved the profile?
I would like to be able to rerun the verification part of the RoomFit on the edited profile, to see the new frequency response graph.
Is that possible? I haven't found any way to do that.
PS: I know that I could use REW but that would require a PC with an attached microphone in the same room as the WiiM/loudspeakers. I don't have that.

Use HouseCurve to check results. It looks like this and runs on your phone using its mic or an attached one.

Thanks but unfortunately this is an iPhone only app. I don't own any Apple products.
Do there exists something similar for Android?
I would prefer to use same measure method as used by RoomFit. So it may look like I need to raise a request ticket to get that as part of the RoomFit functions?

It has been asked for many times and may even have been promised but is still missing.
I believe @Wiimer mentioned this function was implemented in one of the beta FWs at some point, do I remember that correctly? If so, strange that it still didn't make it to the official release.
It would be really great to have the option to just measure the current response of individual channels directly from WHA, to be able to visualize the effects of both RoomFit and EQ. As you said, it can be done with REW but it is significantly less convenient.
