Room correction

[steadyshot]

It‘s not at all super weird - it‘s setting priorities according to customer demand… which is great! The development team has not endless resources …

I could switch a streamer at any moment... It is Wiim who should strive for building a reputation not my job… If RC is to work reliably on any phone it needs an external mic with calibration file. Otherwise good luck with the mic jungle! That is obvious …

It would be ridiculous to allow external mics but not accept calibration files.

 

[slartibartfast]

Correct. I have some experience with measuring but getting it all aligned is something else.

Eqing left/right as a pair isn't ideal, my left and right speakers response is totally different, so Eqing the sum is not best method. The factor in sub being switched off during measurement so it's not eqd nor phase aligned...

It's good this software is available but it's a long way to go compared to what is available on avrs.

Surely the sub is not turned off during measurement.

Then how do you measure each channel individually? Or get each channel time aligned?

Until individual channel measurement and alignment is added it's just a poor method.

You haven't tried it have you. People say it works.

You don't understand how it works. You want to EQ each speaker individually and sub individually

I can provide graphs showing left and right have two totally different responses.

Do you have umik1 mic? I do.

No I don't have a umik1 mic. I am not worthy.

Not sure what your slightly aggresiv way supposed to bring… ?

I don‘t know your room, but in my case - a 2.2 setup with subs in different positions - it works brilliantly!
As others said, just try it!

Suggestions that it should be a feature request. It is so obvious that it shouldn't need to be a feature request.

Here are my left and right responses. You can see if you correct for combined LR , it isn't the optimal correction for one specific speaker. It would be ok if responses for both just happen to be similar across the range. You'd also have to factor in phase also, that the speakers are correctly time aligned by Wiim prior to measurement/correction

I have auto/manual PEQ in my AV pre with individual PEQ filters per channel, so superior to that of the Wiim (but a lot worse than bigger brands room correction)

Auto sounds trash, it applies several +10db boosts to make response as flat as possible it transforms high quality flagship towers into speakers sounding what you get in cheap ass micro systems (if not worse)

Mine are slightly different measured with an imm6 as well. I am still waiting for per channel PEQ. When it is I'll try correcting left and right separately then measuring the corrected response of both together to see how it looks.

yeah I think people are jumping on the bandwagon about this, people with little understanding, it's great it's a additional feature but it needs a few improvements which I'm sure will happen over time, hardware depending, and warnings.

I'm using 300W amplifiers into 4ohm, but using multiple positive boosts on only 60W amp is not good idea.

I would recommend a "apply cuts only, no boosts" as a default EQ computation, a setting can be enabled to disable that but a warning pops up "WARNING boosting frequencies saps considerable amplifier power, we are not responsible for any speaker or amplifier damage" etc

Any positive boost requires a reduction in maximum output volume to avoid clipping of the input signal anyway so the WiiM amp won't clip but it will be a lot quieter so still better to avoid boosts.

 

[rccarguy]

Its not as trivial as some people thought. Or still think. RC done right is one of the most complex parts in HiFi. And even then, who defines "done right"? In home audio we are still at the beginning.

Decades of R&D from multiple companies.
Need a good foundation for correction otherwise you're just guessing. From Wiim, using inaccurate, uncalibrated phone/tablet mic, and combined L/R response is not ideal.

It's not about the feature itself, but about the priority that should be given to implementing it. If only 100 people really want/need it, but 10000 people will just use the built-in microphone of their iPhone, it won't be at the top of their list. Hence why Brantome always suggests submitting tickets. If 100 people submit a ticket for this and only 10 people submit a ticket to add a new streaming service, the external microphones will probably get placed higher on the list.

They have already said external microphones will be supported, this is about a separate request for calibration support for those microphones. They go together surely.

I did not want to say something against. The mess with all these AVR automatic room correcting stuff is still present in my old head. I was (it has to be done again in the new flat) satisfied with Roon (ARC) and my miniDSP. But more and more I got bored with the efforts. A new LP shelf or the dog decided to have another chilling place could change the whole situation

Take a cat and stay on streaming, less significant organic mass and no needs for new shelves...

Think its true what @Steve Woodhouse wrote in a neighbor thread: "So we’ll all end up ‘listening to the room’ to some extent."

It's the sad truth, room puts last words on everything...
