Custom room fit target curve

[gasolin75]

Is it possible to make a custom room fit target curve or download additional filters
Can i have 2 or 3 profiles like having flat,harman and B&K roomcorretion profiles i can switch between


How big is the difference between B&K and Harman

No, that's not possible at the moment. If you are an iPhone user you can use the app HouseCurve where you can create a custom curve and do your measuring directly in this app. You can then create a custom PEQ which you can enter in WiiM Home App under RoomFit manually.

Yes.

"Harman" has significantly more bass than the "B&K" curve - so the choice would depend mostly on how much bass you want.
The "flat" curve is meant for extreme nearfield, for very dead rooms, or for loudspeakers with non-standard directivity patterns (e.g. omnidirectional); apart from those in most other use-cases it will sound bright.

I like bass but the Harman setting is just a little to much bass in some case

I want to switch between them to choose what i like or a custom curve like you can do with a IK Multimedia ARC Studio

Could that be made in a future update so it can be saved for easy change, 3 profiles and more target curves like a midrange setting for those who make music and want more midrange focus for hearing all the details or listening at night with less bass and more clarity

My suggestion would be to use a neutral curve to start (IMHO B&K is a very good choice in most cases), and then use EQ to tweak the amount of bass. Note that now you can use RoomFit and EQ (GEQ or PEQ) at the same time in most WiiM devices.

To add a bass boost to the curve in "EQ" (PEQ) screen you can add a single PEQ low-shelf (LS) filter with the center frequency at 100Hz (or 150Hz), Q=0,7 and gain corresponding to the amount of bass boost you'd like. Since the boost applies equally to both channels I'd suggest to use "stereo" mode. You can save different EQs as profiles as well - so you can easily switch between them.

To get an answer on this I believe you'd need to make a request directly to WiiM using the WiiM Home App (More > Feedback).
But IMHO you can ge the same result already by using just one target curve in RoomFit and then using EQ on top (as suggested above).

I have tried lowering 31,63 and 125 hz with 1 db it seem (sounds) better (som songs still sound like i have my subwoofer on)

B&K enhances the lower tweeter, i do not want to do anything to the highs then making it neutral,flat

I by accident deleted my flat room correction, flat and then 31-125hz (eq) 1 or 2 db up

Have to experiment with both settings

Regarding this, I'd advise to limit RoomFit to lower frequencies only (below approx. 500Hz).

If your loudspeakers require correction above that then I'd suggest to check if an EQ profile for them exists on spinorama.org and to configure it as an EQ profile. Just make sure to only load spinorama.org EQ filters above >500Hz (if that was the upper limit you used in RoomFit).

Hope this helps!

No spinorama

I just chosed as wide as possible 30-20khz eq is fine tuning

Flat to me was a little o bright, bass often needs 1-3 db , target curve like Harman don't just do 2 db from 50-200hz for more bass, it's does more specific things,adjustments that isn't just 50-200hz + 2 or 3 db like on studio monitors

The RoomFit shall give you a baseline and it doesn't have to sound good but it will equalize the worst room resonans and then when adding the EQ (PEQ or GEQ) on top, it gives you the clean sound of your liking.

I always use the flat RoomFit target curve and then select the EQ depending on what is playing.

PS: No need to post the same questions in multiple threads. It's just confusing.

It is not a surprise you found the flat target bright - see the other thread for an explanation.

Using EQ much above 500Hz based on the in-room response to fix the response of your loudspeakers (like you're trying to do with RoomFit) is just not a good idea, as it can easily make the response worse and introduce new resonances to the direct sound response that could be audible. There's less chance of such undesirable results if using higher response smoothing (e.g. 1/3 or even 1/1, instead of 1/12 or less), but then low frequency resonances aren't addressed optimally.

If your loudspeakers weren't measured anechoically that makes things more difficult, especially since RoomFit doesn't support variable smoothing.

You could try this:

1. Run Individual Channel RoomFit with 1/12 smoothing, B&K curve, and frequency 30Hz-500Hz , and save the result as a new profile. This will be your room correction.
2. Run Stereo RoomFit with 1/3 smoothing, B&K curve, and frequency 500Hz-20000Hz, and save the result as a new profile. This is your loudspeaker correction. Note that you will need to manually configure these RoomFit PEQ filter values to a new EQ profile, and enable the new EQ profile at the same time as the RoomFit profile from 1.

A better/more flexible option would be to create a full range correction in REW (where variable smoothing exists as an option) and then configure the filters manually in WiiM. But that is a bit more complicated to do. Perhaps this post will be a good intro, and this thread is also a good resource.

Again, even under ideal circumstances full-range correction is not guaranteed to work well. The only "right" way to equalize loudspeakers at mid and high frequencies is the one based on anechoic measurements. Fortunately, there is a way you could make (quasi-)anechoic measurements of your loudspeakers in your home, e.g. using the guide in this thread. This is again not trivial, but IMO well worth learning to do if you're interested in audio.

Havn't tried with my subwoofer, and havn't tried any more advanced adjustments with the mic dayton imm 6c i just got today

So fare i think it sound good full range and eq for fine tuning for just a little more sparkle or more or less bass

What min/max gain and max q would you advise for these Roomfit runs? And should non-boost mode be on?

 

[gasolin75]

Personally i just have to try all target curves

Perfect would be a setting that don't needs adjustments after room correction from the eq

Harman does add to much bass for me, so fare 31-125hz is down by 1.5 db and is still above avarage (sounds like i have 2 floorstand speakers with 2x5½ woofers pr speaker)

I might try -2db
