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.
