Beta Test: Audio Spectrum Display for WiiM Ultra

[QuarryHunslet]

i haven't noticed that until i read your comment and then..i switched back to VU meters (that weren't moving) and switched back and forth to "Original Signal" and they were moving again...so if I got this right, the new beta Spectrum analyzer switches to "Output Amplitude" display by default, and removes the option to switch between modes completely

Yes, there isn’t currently an option for the Audio Spectrum Display to use the Original Signal, but hopefully it will be added.

I like it. Works great for me! Thanks WiiM Team

Definitely has broken VU

No revelation to add for this feature.
Installed it for 2 mins, then uninstalled it again.
Currently completely pointless when using the ultra for volume control.
And yet also when it's not...

My ultra is optical out to a vibelink.
There's no way I'm going to use the vibelink's volume dial (as nice as it is to use) instead of any of my tablet buttons, the remote, the ultra dial, the wiim app.

Let me know when it's on par with the RME

The spectrum analyzer should be connected to the original audio signal and not to the volume on the wiim ultra. This way for the majority of users who listen to the wiim ultra at 100% it is unusable. Add more colors and it would be great!

when we know the importance - usefulness of an element like an "overload" downstream of all signal processing...and that for all Wiims...not just to animate "the screen"...


(The Ultra was just released on July 24)

At 100% volume it should actually show the same as the source (original audio signal), except any EQ or pre-gain.

It doesn't work at full volume, that is clear. It is expected to never go to 0 (dBFS) but may come close. Anything that is at zero may cause distortion.

See https://forum.wiimhome.com/threads/beta-test-audio-spectrum-display-for-wiim-ultra.8385/post-153332

There is clearly some work to do with the scale and the displayed values, before final release.

The scale should be from -90 dBFS to 0, with the correct logarithmic values.

dBFS=20*log10(volume/max volume)

The volume being the 24 or 32 sample value.

To be useful it should show output before any volume limiter kicks in!
