Amp ultra review

[Burnside]

He states that the speaker and subwoofer sync feature is using the phone’s microphone. I was thought that this feature was using the microphone on the device itself. Has this changed for the amp ultra?

Or he’s just wrong?

It hasn't changed he is just wrong

Yeah so now I’m confused as well.

I’ve noticed that AI reads how you posed your questions and your context, and will angle its response to be more along the lines of, “what you probably want to hear,” more than what is outright correct. It’s insane.

I bet that If you behave hard enough as a flat-earther to AI, it will start providing flat-earth friendly responses. The thing is absurdly stretchy when it comes to facts and logic!

I’ve also noticed numerous instances where it was outright incorrect.

That’s what I thought. He should’ve have come on this forum and did some research first before making a false claim.

I can easily test this with my Mesh-System at home. I just have to go to the basement in our house with my phone and try the Subwoofer & Speaker Sync from there where my phone mic has no chance from hearing anything from my speakers.

There is no way that the phone microphone can be used for time alignment. The delay between the phone and the WiiM device is unknown, high and variable. So a local microphone with a known processing delay is only option.

This should ideally be at the listening position but if the WiiM device is not to far away the measurements should still be fine.

Room Equalisation Wizard can be used for time alignment so I don't see why an external mic can't be used.

And he consistently ignores the existence of AlexaCast for Amazon Music when rhyming off casting options…

I agree. For the purpose of time alignment of sub(s) with the mains we're only interested in the relative timing difference at the listening position.
It doesn't really matter if the timing difference is caused by sound propagation delay in air, by DSP, or due to a combination of both.

Was going to say this exact same thing. All that matters is the difference in total delay between the speakers and the sub.
