Are any of these updates heading for the WiiM Amp? It hasn't had an update for more than three months.

 

[canard]

I was going to ask the same question regarding the rest of the range...the all-in-ones or other streamers
;-)

 

[harkpabst]

This sounds to me like the most significant update in many months.

Really looking forward to this.

Playback Screen: Added a vinyl-style playback screen for a more immersive experience.

Does this vinyl screen have the hands of a clock by any chance?

I‘m afraid you might be right. Sad!

 

[F1 Fan]

Looks like a nice update!

Maybe they mean this one?

1. Sub & Main Speaker Sync: Automatically aligns subwoofer and main speakers for improved timing at the listening position.

There’s a subwoofer setting that align both main and sub by delaying sub, wondering what this brings?

You can now measure latency at your listening position using the phone's mic or an external mic.

This approach is better than previous implementation?

 

[EddNog]

The original implementation is absolutely broken because it measures it where the streamer is, not where your ears are.

Of course, the previous implementation didn't work and complaints were made about it from the time it was introduced.

 

[hipoagumol]

Has anyone tested,?is HDMI having the options and working as in beta?
I.e If Tv switched on, it won't throw audio towards Ultra unless Ultra has HDMI input selected.
@hgo58 knows what I am talking about

Never get your hopes up when something is called "immersive." That seems to be a good rule of thumb.

Sub & Main Speaker Sync: Automatically aligns subwoofer and main speakers for improved timing at the listening position

Wasn't that already the case?
Or does that refer not only to timing but also to level matching?

 

[Burnside]

Wasn't that already the case?
Or does that refer not only to timing but also to level matching?

Doesn't this refer to the change that the measurement is now done at the listening position via your phone/mic rather than using the internal mic in the WiiM itself?

Burnside is correct; the original algorithm used a microphone inside the streamer to attempt time alignment between the sub and speakers, which is, fundamentally, an absolutely, completely wrong and utterly broken manner in which to do this. The update corrects the algorithm to utilize a microphone at the main listening position for time alignment purposes instead.

[Saponetto]

Silly question... Shouldn't the wifi network latency be considered as an added delay/timing factor to manage also?
And what if network latency changes?
The defined corrective value for the listening point is anyway written within the Ultra's DSP without further need to be checked?
