Beta Test: Automatic timing alignment for Main Speakers and Subwoofer

[slartibartfast]

I see that menu in my settings. The thing is nothing has changed. It’s still the manual settings.

What is your firmware version?

 

[slartibartfast]

When you run rc does it include the timing in all the process?

No, it is a separate setting.

Did you have the latest app?

Yeah I just checked the App Store and last update was 2 days ago.

It's possible that there is a phase anomaly between sub and speakers so the WiiM algorithm is delaying the speakers more because of this. An 8ms delay is 'virtually' placing your main speakers 2.7m* behind the sub so that the sound peaks hit the microphone concurrently. It might be worth reversing phase on the sub and repeating the measurement.

I will try to explain using these examples from old measurements taken from my system using an Earthworks M23 Mic

The top image is the initial impulse peak of the main speakers (37ms)
The Lower image uses the initial impulse peak of the sub (41.6ms) as shown by the first dotted vertical line.
So the delay to the main speakers needs to be 41.6 - 37 = 4.6ms

However if the phase on the sub was reversed 180deg then that image would be upside down & the large dip would then be the initial peak at 59ms (second dotted line) so the delay required for the main speakers would now be 59 - 37 = 22ms.
Neither speakers nor sub have changed position in the room but a change in phase changes the point in time that the signal arrives.

In your case I suspect that the WiiM algorithm has made the 'correct' adjustment so you do not need to worry!

(*sound travels at 0.343 meters per millisecond so 8ms = 2.744m)

Well, I switched the phase to 180 degrees and still get the same 8ms delay.

It look like there’s only 2 beta testers. It doesn’t look like it has issue.

What do you mean?

What do you mean?

I’m only seeing you and @slartibartfast saying something about this beta. Maybe there’s more but not saying anything aside from reporting issues.

That is a different beta. Different to mine at least, mine isn't even marked as beta.

Oh ok I see what you mean. It’s possible wiim might have to iron out some more kinks. I figured the timing would have been built into RC.

Yeah not sure what’s going here. I wasn’t on beta last night. I signed up for WiiM to whitelist my amp yesterday and I come home from work and now is she is in beta. Who knows lol

His build date was June 24, that maybe different beta.

June Where did that come from? How could that appear today?

Yeah this is the beta where I am able DLNA audio out. I think they gave me the wrong beta.

Yes you got wrong beta should be same as him.

Since yours is labelled as beta you can leave it by clicking on it and choosing to leave.

 

[BK308]

Thanks guys leaving that beta now and going on the normal version. We’ll see what happens.

Send them message so you can get same firmware as him.

 

[slartibartfast]

I want to see if anyone gets a different result than 8ms
