Resolution of streaming

[Angelos58]

Is there a way to know with wiim home what resolution of current streaming? Bit and Herz. I stream from Qobuz and the source is Lan.

Thank you, but is it the nominal streaming or the real one?

I have confirmed when using LMS at least that the format and bit rate displayed in the WiiM app is of the source file and does not change when using a transcoder plugin so this is not necessarily what the WiiM is receiving but what the player, squeezelite in my case, is reporting.
The only way I have been able to verify is by using an external DAC with a display.

So there isn’t in WiiM a way to know the effective bit rate

My former setup with the Pro, Roon and a few external DACs confirmed always what the WiiM app showed.

I tried with Audirvana Studio on my iMac connected wireless. My WiiM Pro Plus is wired LAN cable.
When I start Audio Scan, Audirvana register a Bandwidth less than expected. Like the streaming would be in wi Fi mode, but the Wiim Pro Plus is in wired mode Source: Ethernet. How can I verify that the WiiM streaming is via Lan and not wifi?

- Switch off wi-fi in the WiiM app.
- If you are a strong non-believer you can check in the UI of your router.

I can't switch off because there isn't nothing to switch

Good news! Then the ethernet cable is on his place and does the work.
Disconnect it and the WiiM will offer WiFi after a re-start. Connect it again and the WiiM will tell something like "you need to have an ethernet connection to disable wi-fi". Shorter version: If an ethernet cable is plugged in the WiiM it is in charge.

thank you. And why Audirvana in Audio Scan registers a low bandwidth ?

 

[Achim1811]

No idea, never used Audirvana. For me all this resolution schnickschnack above CD quality is nonsense, was nonsense and will remain nonsense in future.

What exactly can Audirvana running on you Mac measure concerning your WiiM?

The bandwidth required for HiRes audio is far less than the bandwidth available with WiFi ...

I do not know. But some results are disturbing. Files that should be Hi Res and that are even Lossy on Audio Scan in mp3 quality

Audirvana Scan Facility - does it get file quality scans wrong?

The Audio Scan analyses the audio content of the track played and therefore is only available during playback. It is based on an algorithm that reveals its actual resolution and checks if it matches the audio quality featured in the file metadata. It has been developed in partnership with Ircam...

So does it only work when playing tracks using Audirvana? Surely it can't be used on tracks played directly on the WiiM.
It seems unreliable anyway based on this

Audirvana Scan Facility - does it get file quality scans wrong?

Using the Scan Facility in Studio to look at some of the FLAC files I have ripped off CD via EAC set up for Bit Prefect (as much as humanely possible) copies then ‘compressing’ the WAV files with FLAC. For some of the Albums - Audirvana sees the FLAC files as CD ‘quality’, but for others the...

is there an alternative for Scan Audio playing via WiiM?

Why do you doubt what Qobuz is telling you? WiiM.doesn't resample does it?

I had some email exchange with WiiM about Pandora streams. They had been showing the PCM decoded kbps (larger) instead of the source AAC/ALAC kbps (much smaller), so when they changed (in the UI), it was noticeable.
