I hope there can be a delay setting of the speaker, and the distance has been adjusted.

I hope to have this function, because the distance from the speaker to our listening is sometimes not very symmetrical, which will make the sound time difference a lot, so I hope that the distance can be used to adjust the delay of a few milliseconds of the left and right speakers.

Delay from what?
You mention symmetry which implies one speaker to the other, but then mention delays for both channels.
 
How non-symmetrical?
1 ms is about 30 cm / 1 foot.
A few ms implies your speakers are about 1 metre off symmetrical from your listening position.
Adjust your speakers / position! ;)

I’ve highlighted the key word. It implies that sometimes it is symmetrical.

If you were to input a delay for a speaker to handle the times you’re not central, then it’d sound ‘bad’ when you say in the symmetrical position.

You’d need to turn it on and off every time you moved.

Plenty of AV amps control speaker delay, but I can’t think of one where you can turn it on and off instantly with one click of the remote; you need to go into menus, sub-menus, and sub-sub-menus.

And finally, delay between the signal coming from each speaker is not the only problem with sitting off centre, and indeed not the main one. As such, it would cure little.
 
I don't have the luxury of a single dedicated seat in the RSP/MLP, so have to sit either side of the central speaker line. My avr's distance/delay settings enable me to setup the left or right seat as the sweetspot, and the delays between left and right, when sitting 40cm off central at a distance of approx 2m from the wall (one speaker obviously much closer than the other) make a huge difference to soundstage perception. My speakers have good off axis response, so tonal balance is retained pretty well, just the positioning within the stereo image is off quite a bit with the wiim uktra vs the avr. Would second this requirement for sure

Back in the day even audiophiles made do with a balance control 🤣
 
True. My trusty NAD c320BEE is awaiting repair in order to be brought back into duty with my orignal Mission 771s to provide a little nostalgic sound for the office. The NAD have a balance control...but I even put off releasing the tone defeat button for fear of the purist police. Times have changed ;)

My Mission Cyrus 1 didn't even have tone controls, or a balance control 🤣

They recognised their mistake and added a balance control to the 2nd and 3rd generation, though. :P

The WiiM Home app provides balance control as well, but it doesn't add any delay to one channel, of course.

Even with additional delay for the closer speaker the overall sound will not be exactly the same as in a symmetrical listening position. The room still makes a difference.
 
I think having a delay setting for speakers would be very helpful. AV receivers already have this, but it would be nice if simpler systems like WiiM added it too. Even small delay adjustments can really improve the sound when speakers are not placed evenly.

Sure they do, but the scenario is very different.

With stereo playback you are asked to normally sit equidistant to both speakers. That's the norm and not too hard to do (with few exceptions as above). No individual delay needed in this case.

With multi-channel playback you have to deal with 5, 7 or more speakers and it's usually totally impossible to sit equidistant to all of them.

Adding a subwoofer to the picture again means that it won't be placed at the same distance as the main speakers in most cases. WiiM has that covered already.

This is a niche use case. Not unreasonable, but complicating the user interface and providing value to just few users.

I believe you are absolutely correct 🙂.
If the AVR speaker distance setting is different for the front speakers, the speakers and listening points will need to be readjusted. (Assuming AVR room correction and mic are accurate.)

I use a laser distance measuring device in conjunction.
 
The room makes the biggest difference of all really. I've spent many hours with REW, MSO, A1 Evo etc doing measurements and analysis and corrections.

Physical distances have little to do with actual delays and the use of distances within AVR as a proxy for delays. The delays in the entire signal chain to the speakers are what needs to be accounted for, and this is what distance estimation based on timing references/test tones aim achieve.

Not sure how "niche" this requirement is though. I suspect few setups in practice have a single seat for a listening position. I used to when I lived alone years ago, but not practicable for most I would suggest. Whilst different delays will make one position worse, the occupant of the second seat in my case likely couldn't tell ;)

Given there are already pages for balance and sync, Wiim have shown themselves capable of clean UI implementation even when adding more complex feaures; they just get added to the deeper dive/advanced pages.

How and why could or would you account for delays "in the entire signal chain" in a stereo setup?

From my point of view this is a completely different topic. Are you aware that most (all?) WiiM devices have a built-in mic to enable multi-room synch?
 
Yes, I'm aware of the Wiims mic for room sync. Indeed that is a totally seperate topic. Think perhaps you may have misunderstood/I wasn't clear. I was mainly referring to subs and/or active speakers, or where rca preouts are being used that are then going through a dsp. The measured test signals for channels that are not going through the avr amps but through additional dsp will be delayed, and thus the measurement mic or avr "sees" them as being further away, hence would delay these channels less/the others more depending.

Just exactly what the Wiim is doing with the subs and mains when it attempts the sync. Though due to the lower frequencies of subs this kind of measurement isn't always too accurate and some manual tweaking/refinement can often improve things.
 
OK, Insee.where you're coming from. As long as you stay within the WiiM stereo "universe" (and do not integrate it e.g. with an AVR) the delay due to WiiM's DSP is common to both channels, of course.

Agreed, directly measuring the delay in the bass region is not that easy and I wouldn't want WiiM to try and implement such measurements.
 
Ive got a mini dsp and 3 subs, so thats running from the ultra sub out atm. Wiim have tried with the sub and mains sync, and I'll be testing that shortly with rew and looking at the group delay measurements to see how well it is doing. I've an x3700h too, with both preouts going through a bob gold rca switcher before going onto the monoblock amps. Quite a bit of fiddling and balancing going atm, but it's all interesting
