Enhanced Room Correction is Here!

[Wiimer]

A quick comparison of UMIK-1 USB mic and iMM6 3.5mm jack connected mic. You can see the issue with the iMM6 at low frequencies when connected to the 3.5mm jack socket of a Pixel 3a.

My IMM-6 had the same low frequency drop as yours.
I don't know if the problem is with the phone or the IMM-6, however I did not see this problem with the IMM-6C.

Well, it just got even more confusing. I remembered I have a Galaxy Tab that has a headphone jack, so installed the Wiim app and set it up. I took three consecutive readings with the sound system hardware settings unchanged from earlier. I now have another completely inconsistent dataset, and not even sure what device is throwing up the errors!
I noted that it showed the mic as "h2w" but the results are wild. I didn't take any with the built in Tab mic, as by this time my wife and both dogs have gotten p1ssed off at the whooping noises

I'll have to wait and see what I get with the S23...

I suspect the ADC in the phone. I had a similar issue trying to use the iMM6 with REW using a TRSS to USB adapter which was even worse. The USB version of the iMM6 is probably fine.

Yes of course!
The string appears at one of the stages,you can trust my word

It's not a question of trusting you, but if we're talking about bathe same thing.

You said:

Yes, sure.
Recisely, it is recognized by Samsung

On Android phones hardware support for external hardware is not as standardised as it is with desktop operating systems. Your screenshot made it clear that the WiiM Home app recognised the mic. That's all that counts.

I do not know if it matters…

It shouldn't matter. You can place the PEQ filters in any order when setting them manually.

I'm not really surprised.

We're thrilled to announce that our Room Correction feature is getting a significant upgrade! Starting today, WiiM devices will receive big improvements to Room Correction performance when tuned, taking your listening experience to the next level.

What's New?
Broader Frequency Range: Expand the default 40Hz~4KHz frequency range to an impressive 30Hz~20kHz, enhancing both bass and high frequencies.

How to Experience the Upgrade:
To take advantage of these exciting improvements, simply update to the latest version of the WiiM Home App on your iOS or Android device, and make sure your WiiM device is running the latest firmware. Most of these changes happened server side, but we recommend making sure you have no updates pending.

Tips for Optimizing Room Correction:
A good way to evaluate the new Room Correction is by starting with bass frequency adjustments - which is much simpler than adjusting both bass and treble simultaneously. If your previous range was 40~4k Hz, try adjusting it to 20~4k Hz to see if it improves bass performance. Treble adjustments are more speaker-dependent and less influenced by the room, plus users have varying preferences for treble. The update improves treble alignment with your target curve, offering more precise control in the high-frequency range.

Questions or Feedback?
Feel free to share your thoughts or ask questions in this thread. We're always here to listen and help.

Thanks for being part of the WiiM community!

Hello. A happy new Wiim Ultra owner here. I am a beginner in audio, so really the EQ graphs don’t tell me much. Can someone please assess my room measurements after room correction? Thanks!

 

[Lvnmuskoka]

I found Wiim room correction isn't accurate at all above 5khz or so. It also added the same 8khz and 16khz peaks that you have, and made my system sound way too bright. Try stopping the room correction around 4khz to hear if it's much improved. The lower the frequency correction the better, at least down to 500hz anyway.
If you post before correction measurements, might be able to give better recommendations.

Hi.
The first screen is a fully automatic setup using beta functionality.



The next one is slightly adjusted manually.



The PEQ auto curve passed test by Carlos Santana’s “While My Guitar Gently Weeps” track.

First pedal strokes on bass drum didn't break the windows glass in home

India Ari's chest vocals on the track are dense and richly colored.

What frequency range did you choose and which mic?

Hi, I just bought an wiim ultra, I haven't opened it yet, it's for a second chain for which I'm still waiting for accessories, such as a power strip, I have both iOS and Android at my disposal, I also have an old iPad with a jack, which Dayton microphone should I buy? For a more accurate measurement, wouldn't it be better to have an extension to distance it from the phone? Or does it make no difference? Thanks.

You'd be better off using whichever devices has a USB connection, and buy the Dayton iMM-6C.

The important distance is that between the Mic and your speakers, not your phone

If you want Dayton, then the IMM-6C with usb-c. I plug it directly into my phone and it works great.

From cal files I have seen it does have some roll off at low frequencies. When cal files are added to WiiM RC that issue will disappear. Whether you like the result with less bass is another story

 

[Berico]

OK for android then, certainly the measuring distance is important, I thought it would be better to fix the microphone to a rod isolated from the body and from reflective surfaces (tab or phone)

People do say that but in all honesty who actually does it

 

[ArthurStereo]

You can correct the RC correction based on the parameters in the calibration file that comes with the microphone. Or even better, buy the HouseCurve app if you have an iPad. It's a great, inexpensive app and I use it with great results.

I don't use any extension cords. I plug it into my phone, tilt my head back and hold the microphone at ear level towards the speakers. Our body is also an acoustic element, so I sit in the sweet spot during the measurement.

 

[Berico]

I have some sound-absorbing cloth left for passive treatment, I will wrap the tablet even if a wool scarf is enough, I saw that some microphone calibration data was collected, then how did it end? They were inserted in the latest update, sorry but the purchase is not planned, nor is putting a second chain so I am not very informed about the wiim world, I have read a lot these days. Yes I know HouseCurve, but is it possible to load curves made by other programs? sorry but I can't quote.

 

[ArthurStereo]

For now, you can't load files into RC from other programs.
After setting the correction, I easily write the parameters from HouseCurve to the Wiim parametric equalizer and it's very effective.
