RoomFit Help Guide

[nerone]

Hi everyone, I'd like to use RoomFit for my 2-channel stereo system.
Could you advise me on how to start adjusting RoomFit settings?
Thanks.

I repositioned the speakers and sub to more 'optimal' positions now. It seems I may have to reduce the sub's volume somewhat - or shall I just let the room correction take care of that?

That looks much better, good work!
You could reduce sub level by 2-3dB, but you don't have to - as you said, RoomFit takes care about the level.

How do you like the sound with this latest placement and calibration?

EDIT: BTW, you can now use EQ to tune bass level to taste. A single band of low-shelf (LS) PEQ with frequency=150Hz, Q=0.7, and with gain to taste should do the trick.

Hello

I have a question. When I use the room correction measurement with Wiim Amp Ultima (I'm a beginner, unfortunately), there's always a boost at 8 kHz. We've discussed this in several forums, but why does it occur for me?

It's a whistling sound, I'd guess around 8 kHz, so in the very high frequency range. It doesn't bother me at all when listening to music. How noticeable should it be?

And now I've noticed that the final correction probably isn't even showing the correct result! When I access the saved values, this 8 kHz boost is no longer visible in the modified measurement results.

I'm confused now.

Shouldn't this graph from my saved profile show the final result? I've shown a slightly different graph so far, and not the correct one, without the 8 kHz boost.

I've shown this screenshot in other forums where the frequency increased to 8 kHz. And that probably wasn't even the correct result? But here's a graph below, which comes from the saved final result, where the 8 kHz peak is no longer visible. Is the one from the saved graph relevant?

The 8kHz peak is ghosting picked up by your phone's built-in microphone (or it could be internal phone noise). Since this sound isn't coming from the speaker, you can safely ignore it.

Edit: According to Gemini, the built-in microphone in phones often intentionally boosts sensitivity around 2kHz to 8kHz. This is apparently called "Presence peak".

Alright, everyone!

I just used my Denon AVR-X2400H with Audyssey to calibrate my Elac Debut Reference DBR62 and Teufel Ultima 40 speakers, and here are the results.

After calibration, the Denon sounds significantly better with both speakers (Elac Debut Reference DBR62 and Teufel Ultima 40) than with Wiim and its useless RoomFit function!

I'm even considering returning my Wiim receiver because Wiim calibration is completely pointless! It simply doesn't improve the sound. Denon's Audyssey measurement technology is clearly superior to me! Until now! Who would have thought?!

Here are the results.

So, Leute!

Ich habe gerade meinen Denon AVR-X2400H mit Audyssey verwendet, um meine Elac Debut Reference DBR62 und Teufel Ultima 40 Lautsprecher zu kalibrieren, und hier sind die Ergebnisse.

Nach der Kalibrierung klingt der Denon mit beiden Lautsprechern (Elac Debut Reference DBR62 und Teufel Ultima 40) deutlich besser als mit Wiim und seiner nutzlosen RoomFit-Funktion!

Ich überlege sogar, meinen Wiim-Empfänger zurückzugeben, denn die Wiim-Kalibrierung ist völlig sinnlos! Sie verbessert den Klang einfach nicht. Denons Messtechnologie Audyssey ist für mich deutlich besser! Bis jetzt! Wer hätte das gedacht?!

Hier sind die Ergebnisse.

Why are you repeating the comments from another thread?

The RoomFit works really good for me. Just need to set the measures to fit your equipment setup

And use a calibrated microphone

 

[Djdragon]

And use a calibrated microphone

Do I need to calibrate the microphone before using it? Or can I just plug it in and test it? Why do I need to calibrate it at all? Why isn't it calibrated at the factory?

Are there alternative, cheaper microphones that are just as good? Which one is better than the microphone that came with my phone?

It is calibrated at the factory. It comes with a calibration file which can be imported into RoomFit. The Dayton Audio imm6C is probably the cheapest USB microphone. It plugs directly into the phone USB socket while the UMIK-1 connects via a cable.

There's no point in comparing an actual measurement, the cyan curve, which shows the big peak due to the low quality smartphone mic, to the curve created by the correction filters.

The magenta curve on the final assessment screen is the same as the correction curve, just displayed at a very different resolution.

Without knowing your RoomFit settings (configured before running the process) it's impossible to help you. There's a lot of good information on what to look out for in this forum and in WiiM's FAQ pages.

I notice that Audyssey seems to apply some heavy sounding by placing a dip somewhere in the mid frequencies. Those graphs are pretty useless because there is no scaling for either axis, but most probably the dip is around 2 kHz and ~2 dB. This is sometimes done in an attempt to compensate for a general problem with stereo speakers and the human physiognomy. This results in a softer reproduction of voices and is considered more pleasing by some listeners. You could add the same EQ to your WiiM as well, if you prefer that sound.

I currently have a Dayton MMC6 microphone (the one connecting to a phone with a 3.5mm jack). In the last year I have changed my phone from one with a headphone socket to one with a USB C connector.

The bearded old fat guy who dresses in a red suit is hopefully going to bring me a Dayton MMC6C microphone if he thinks I've been good enough over the last 12 months.

My question is:

Can I have the two microphones with associated calibration files on my WiiM Pro, or do I need to delete the IMM6 and its associated calibration file before installing the IMM6C and uploading its calibration file?

Uploading the IMM-6C calibration file should overwrite and save it.

No, it is not

So you can't have calibration files for two different mics simultaneously

 

[Burnside]

Maybe not, but I can’t imagine too many people having that requirement, nor is reloading a calibration file that onerous.

 

[Wiimer]

That's true, but @AlanB probably won't be using IMM-6 anymore.

 

[slartibartfast]

That's true, but @AlanB probably won't be using IMM-6 anymore.

It will be interesting to see how the results compare with the new mic. When I used the iMM6 with 3.5mm jack the bass rolled off to a greater or lesser extent depending on the phone I used.

 

[harkpabst]

You can actually have multiple calibration files imported into the WiiM Home App. But you need to manually pick the right one whenever you change the mic.

The device running the WiiM Home App is where the files are stored, not the WiiM device.

He replaced his phone, so it probably doesn't have a 3.5mm port.

Thanks Wiimer, both the humour and the advice are much appreciated.

Thanks Harkpabst, can you delete the old calibration files and if do, do you know how?

I know but the results from the new USB mic should still be better unless the new phone has the problematic mediatek SOC.
