Beta Test: Audio Spectrum Display for WiiM Ultra

[azoriusmage]

It does look good and I do miss every device having some kind of level display on sadly only my tape deck has it and of course now my ultra

Question: I can understand room spectral analysis, but… What’s the point for the source signal?

I hope all added feature code is well contained and is completely out of the way if not used. The lighter a DSP is the less noise on the audio pipeline, not even talking about potential memory leaks.

Because it looks cute and that is probably most people's use case

My reason for asking for this is that I want to know what I’m SUPPOSED to be hearing. If I see a bass hit at 40Hz on the analyzer and I don’t hear that hit in-room, I know then to check if my subwoofer is working or not.

To further clarify, our own perception versus an REW or HouseCurve sweep, as we know, differ--that's why Harman curve exists.

I want to be sure that what I see in the analyzer is what I perceive. If two instruments hit at the same time, say a bass drum and cymbals, and on the spectrum analyzer, the cymbals are louder than the bass drum, I should be perceiving the same. If not, I should consider adjusting my settings.

For what I'm saying to be true, the spectrum analyzer needs to be reflective of source recording/signal BEFORE all DSP, of course.

The problem you will have is that the human earing has frequency dependent level sensitivity, thus two equal 120Hz and 8kKz peaks will be perceived at different loudness.

Maybe it is not for you

Hence my point in my other post about the Harman curve.

Technically by now almost nothing they do with the streamer is for me anymore since I no longer actually use a WiiM.

They’d need to add Apple Music natively at the very minimum for me to come back (and I’m not asking for high-res; lossless RedBook would be fine and can be done, just see Eversolo’s native Apple Music app, which sits totally separately from Apple’s own app). Even better if they can add an internal m.2/NVMe slot.

Hi WiiM Community,

We are looking for beta testers to experience our Audio Spectrum option on the WiiM Ultra Now Playing screen feature.

View attachment 28462


Experience your music visually with the new Audio Spectrum display. Watch real-time frequency bars move with your songs, adding a dynamic visual layer to your listening experience. This feature brings your WiiM Ultra’s screen to life, letting you see the rhythm, feel the energy, and enjoy a more immersive connection with your music.

To try this feature:
1. Update the WiiM Home app to version 3.3.9 or later.
2. Go to Device Settings → Device Info → Join Beta Testing and select Audio Spectrum Display.
3. Then go to Device Settings → Screen → Playback, and choose Spectrum as the playback screen.

I have just tried this and it works well. A few comments

1. Switching between playback screens is the opposite of slick. It stops playback entirely, and gives a blank screen for 5 seconds.
2. Once engaged the spectrum display mode is visually appealing, and on a very amateur perspective seems good.
3. Following each note sounding in the Passacaglia and Fugue BWV 582 is pretty cool!

I still think that a good frequency response room test is to inject pink noise and take a look at the room’s frequency response in a frequency analyzer (2024 point FFT OK).

Do anyone know what the scale is and why it's cutting of at -10?

At fixed output to 100% I just see and almost static line of colums all with the top at -10.

That’s odd. It should show the full system dynamic range.

Yes very nice.
But can you add the input signal option as with the vu meters, and I'd like the indicator bars in orange

Yes. -90 dBFS to 0 dBFS.

They rightly address the needs of the many just like Spock.

Did anyone notice that on the original post from Wiim, the screen has the same artist and track name that @Sake was using in the AI fun section?

You mean the one that is also used in the WiiM Home App?

The real implementation do however not look like that.

 

[azoriusmage]

This is how it displays at my normal listening level (20%)
Not that interesting.

The input level with correct values would be more useful.

Agree it barely registers anything at low volume.

Is this only for the ultra or does it also work for the amp ultra?

 

[Wiimer]

Currently, the Beta version is only available for Ultra. With the official update, we can naturally expect this feature to be added to Amp Ultra as well.
