Post in thread 'WiiM Home App v3.2.2 Update – May 23, 2025'

Yesterday at 2:24 AM

Is there a reason for your chosen lower limit of 120Hz? Most of my issues are below that.

This is because the sub and main are connected to 2 WiiMs individually. Cross is 120 hz. try it without the sub this time.

• Wiimer

I did miss it, sorry!

 

[Wiimer]

I'd use the total system lower bound frequency, which would include the sub as well.
Based on the screenshots you pasted that looks to be about 25Hz in-room?

Sorry for the lack of explanation.
I have my main speakers connected to the Ultra and 2 subs connected to the Pro, so the RC on the Ultra cannot correct the full range including the subs. (The subs are adjusted by manual PEQ.)

This is my system.


My room is very small and oddly shaped.


I am the only one who listens to music here, and I always sit on a 60 cm wide camping chair to listen.

This time I tried MMM on the main speakers with the subs turned off.

Two measurements were taken by moving the microphone erratically within a sphere of 30 cm radius from the tip of my nose.




First, the RC was run on Ultra.

Frequency: 70hz-400hz
1/6 Octave
MMM on

[Test 1]


[Test 2]


Next, only the grey measurements are compared.
Tests 1 and 2 overlaped. (Note the different widths of the Y-axis).


The results generally agree, but it is interesting to note that there is a difference of about 3 dB at 50hz.


The PEQ values of tests 1 and 2 are then overlaped and compared.


Is this error acceptable?


Next, I ran RC on a Mini connected to the optical input of the Ultra to evaluate the correction results of Tests 1 and 2.

The stereo RC was run on Mini. (The microphone is fully fixed.)
Frequency: 9khz-20khz
1/6 Octave
MMM off

Overlap and compare the results of Test 1 and 2 measurements.



I was concerned about errors in the low frequencies, so I made MMM measurements of the 2 subs using Mini's RC.

The RC was run on Mini. (The microphone is fully fixed.)
Frequency: 25hz-120hz
1/12 Octave
MMM on

The RC is run twice and the results are overlaped.




In case you are wondering, when the same measurements are made using other analyser apps, the results are almost identical.

The sound source used for the measurements is the WiiM RC's pink noise.
The results were measured twice on each of the 2 apps and the results were overlaped.






Back to the story, when I did the first 2 MMM RCs, I got a strange error on the 2nd RC. The pink noise would play for a minute, but then it stopped halfway through and switched to the test audio (flowing river sound). I have already sent a ticket about this. (Ticket No.533449)

In my experience, audio playback errors sometimes occur during RC runs. e.g., when performing multiple measurements on certain tablets, sweeps that should play 3 times often play only twice. Also, sometimes the test audio is not played back.

This is only speculation, but it may be that for some reason the audio playback becomes unstable and adversely affects the measurement.
(Is the sweep being played back on the WiiM server?)

Note that MMM is much more sensitive to background noise compared to sweep method - that is actually one of the drawbacks of MMM. The analyser simply can't differentiate between measurement signal (periodic pink noise) and environment bacground noise.

So the 50Hz peak could be something like traffic noise, AC hum, refrigerator hum or something similar - which might explain the difference in level between takes.
Unfortunately the best solution is to use a healthy level when measuring, and to make sure you do it when there's limited or no background noise.

Otherwise the agreement between multiple takes/tests looks pretty good to me, great job!

Hi @Wiimer,

We’re currently enhancing the WiiM server to improve playback stability when using Room Correction. Our engineers will review the ticket you submitted next Monday.

 

[canard]

explanations of the methodology and precautions are essential... there are special cases... but without that, there will be no end of feedback for explanations or disappointment etc...

;-)

Ah, that is a very satisfactory explanation.
I believe the 50hz background noise is caused by the fridge in the mini kitchen .

I didn't think that would be an issue as the RC is loud enough... It's a very good learning experience.

Thank you very much!

KEF R3 Meta Bookshelf Speaker Review

Kef R3 Meta

www.erinsaudiocorner.com

Don't worry, the KEF R3 will play way lower than 70 Hz in-room than they do under quasi-anechoic conditions. Compare the response to other measurements performed by Erin and you will see that the response is quite unique and it's by deliberate design decision. They do pretty well (and play surprisingly loud) with no sub.

However, when you add a subwoofer (or two) anyway, I agree with @canard and would use the included foam plugs.

If you have subwoofer correction enabled in the WiiM RC settings, you should look at the lowest frequency expected to be played by the sub, indeed, not by the mains.

I still think that a swept sine in the technically exact MLP is very valuable and the right way to do it, but won't comment any further because I'm on holiday and don't have more time for you.

We can see things more simply...
propose a successful MLP approach, which for certain uses is the most powerful... (and 90dg too?)
and
a successful MMM approach, which is often well-suited for home use...

or an approach involving both...


but simply offer everyone the opportunity to easily compare the results and make their choice based on their tastes and circumstances, which are so variable ;-)

but in any case...
we must be sure that it is technically "successful" and sure.. ( mlp too )

;-)

As always, thanks for your helpful advice .

Yes, as you say, the R3 meta actually plays very rich bass, and there are 2 reasons why I cut it at 120hz and leave the bass to the sub.

1) In my room, there is a big dip around 110hz. (However, on @dominikz's advice I moved the speakers closer to the wall and this problem went away a bit.)

2) To be honest, the bass of the R3s is not to my taste. (I prefer the sound of the Focal in the other room in this respect.)

And yes, I have already pushed foam plugs into the R3 ports .

I still don't know if MMM is right for me. I really like the sound of manual PEQ with sweeps, so I don't intend to change this just yet.

But I always like to try out new features. This time I just tested it, but it was a lot of fun .

Have a nice holiday.
Thank you.

 

[canard]

reading you, the question is whether this mmm has already been achieved...because otherwise it's hardly a relevant comparison... ( mlp too)
;-)

 

[taube Taube]

I apologize again, does anyone know? Moreover, I don't remember how it was in previous versions. Was the year of the album's release displayed?

 

[CliffyBC]

Just been reading thru the posts for the latest Home App release and I don't understand 70% of the stuff on there. Do you guys all have a Audiology degree?
With my rubbish ears, I guess I wouldn't be able to hear all the things being discussed.
But I'm happy just turning on the Ultra and listening to a few tunes which is why I purchased it in the first place. And it does sound better than my old system I had in 1972.Anyone emember Amstrads first amplifier from the early 1970's? Yep, it was real sh*te as was almost everything that Amstrad made.. But it was all I could afford, spent most of my money on Northern Soul singles. Good times.

The Amstrad PC was the breakthrough device for home computing - an msdos device for a couple of hundred when IBM & Apple cost thousands.
