Completed Automatic timing alignment for Main Speakers and Subwoofer

[rccarguy]

I've adjusted the corrections to 6db. Sounds much better than earlier correction, harmon curve. Or the room EQ has been improved.

Is this feature completed as the title of this thread suggests? Many users are saying this feature isn’t 100% ready?

Many Users are expressing their Expectations for this Feature - based on their understanding of Implementations on other Products by other Dev Teams. Only the WiiM Team can determine which set of Goals and Criteria they are/were working toward, what Limitations (Time, Resources, Hardware, Cost) were set.
Comments upthread have shown that certain users will likely NEVER be satisfied with WiiM's Inhouse Implementation, as they have set their Expectations by 3rd-party Products which have Trademarks and Patents and many Years of Development supported by Customer-Paid License Fees. And several of those Commenters haven't even deigned to put effort into trying / testing WiiM's latest efforts, rather than making the effort and giving WiiM a Fair Trial.
I, for one, am eagerly awaiting the retrofit of these Features into the Firmware for my Pro and Pro+ units and the Android App. I do NOT want to see the implementation of a License Fee, especially as some competitors see Fees that are MORE than the cost of a New Pro+ or Ultra.

WiiM say it basically works in the same way as syncing between rooms and they aren't trying to optimise phase at crossover. So as far as they are concerned it is complete.

Do we really know what/how they implemented the "Timing Alignment" Feature?? Do we know that some aspect of "Phase Alignment" doesn't happen, or at what Frequency they calculate that Alignment?? Or are we working from "the Lack of Mention of Phase Alignment" in posts by WiiM Staff?? Doesn't any implementation of Timing Alignment imply effectuation of Phase Alignment, too?? Isn't that likely where some of the anecdotal claims of "wildly wrong" Subwoofer Distances/ Timing might arise (remembering that a single wavelength at 60Hz is about 18ft - so a 10ft/8ms difference would effect a 180* Phase Alignment)??

So it depends on who you ask?

Here is my REW tests, in two channel hifi, as you can see phase dial on the subwoofer makes a considerable difference on the left speaker + sub response at approx 8 locations through out the range

Hi Team,

The auto-calibration feature is designed to improve audio quality by aligning the timing between your main speaker and subwoofer. When a WiiM device, like the WiiM Amp or WiiM Ultra, connects to your speaker and subwoofer, it assumes both audio paths have the same delay. However, if your powered speaker, amplifier or subwoofer adds extra audio processing, it can introduce a slight delay.

This mismatch in timing can cause the high and low frequencies from your main speaker and subwoofer to sound out of sync, affecting the overall audio quality. Our auto-calibration feature uses...

When you say it uses the device's built in mic do you mean the phone mic? What happens if an external mic is used?
I read that Housecurve also has a timing alignment feature so I don't understand how that can be a different approach. I am now more confused by your clarification than I was before

Apologies for the confusion - I was referring to the mic on the WiiM device.

Also, please note that the current setup doesn’t account for the distance between your listening position and your subwoofer or main speakers. For the best sound adjustment, it helps to know the exact distance...

For anyone having issues with the mic used for this delay measurement, there is a super simple fix.
Move the wiim to your listening position during the measurment!

Yes you would need to add a longer cable during this, but that would not affect the measurement.

 

[rccarguy]

So when it does the delay, it uses the mic in the wiim device itself? Not the UMIk1 remote?

huh?

Someone should definitely try that and compare the results to REW

Yes currently!

 

[canard]

I imagine that this has already been discussed but, if I do not imagine in the current state that the capture via the microphone of the remote control in rc mode, we can perhaps use a procedure using it for this type of time adjustment...?

 

[rccarguy]

Yes currently!

wow that's pretty daft. And nowhere does it show that on the app/process

 

[DG77]

No but really, I understand its a bit silly to measure delays with a device not on your listening position, but how often do you perform these type of measurments (”Subwoofer and Speaker sync” / ”Sync Audio”) ?

Just put the Wiim where you are usually sitting when performing the measurement and now you will get the correct distance to the mic from your speakers.

It doesn't say anything in the app about the mic at all. Probably because there is no choice

That's what the UMIK1 is for.

Easier to do with an Ultra than an Amp with speaker cables
(if the cable from the Ultra to the amplifier is long enough)

 

[rccarguy]

To put the ultra where my head is I'd need longer coaxial cable, ethernet cables.

You could use Wifi for this occasion, and perhaps borrow a cable.
But yes it’s a hassle, it is a simpler solution though than having to calculate and add additional equipment just for a one time measurement.

Not saying its perfect, just giving a solution.

you will have to wire the Wiim audio to the DAC or pre-amplifiers speakers subwoofer.... not only wiim moved
