Is bit perfect 192khz 24bit music signal supported on WiiM?

Yes! It's available now. When WiiM Mini supports a bit-perfect function via digital optical output, it outputs the same bit depth and sample rate as your music source. I.e., if your source is 24 bit/192kHz, it will output 24/192. While if yo...

audio quality supported by music services

Many WiiM users ask why they don't get 24-bit/192kHz but 16-bit/44.1kHz from their streaming service while listening on WiiM Mini or Pro. Here is the list of audio resolutions some popular music services offer. Since WiiM Mini or Pro uses the bit...

Feed your output into a DAC that displays bitrate and then believe it

Feed your output into a DAC that displays bitrate and then believe it

In relation to this I wonder why only the input resolution is shown on the WHA and Ultra display. There should be a similar display of outgoing resolution @WiiM Team

 

[harkpabst]

Now I have two WiiMs paired and when I directly during plaing a song check Optical oputput settings, they are still schow me 24/192. I understand it can be fix in settings and differen in reality.

The optical output setting cannot revert the conversion that has already happened before due to grouping.

proof? I din't find official info, just some reports on forums.

I will gladly help, I don' feel like proving anything to anybody.

Second - how can I know that any member is experienced if they don't give proofs/numbers?

You didn't accept as a proof the numbers you've been given because you didn't like them.

These links are relevant, of course, just not for grouped or linked WiiM devices (also known as multi-room music). Have a look at the latest WiiM Pro and Pro Plus roadmap instead. Scroll down to the last section "Features We're Thinking About In Future Updates". The first bullet point reads "Multiroom of Hi-Res Audio".

WiiM Pro and Pro Plus Roadmap

Updated on Oct 4, 2024 What we're working on … We want to give you visibility into some of the features we are working on. For a complete list of released features, please refer to our official release notes. If you want to make a feature...

Is it so hard to see that we just want to protect you from a disappointment? You don't have to believe us, but you have been warned. I'm sure you won't hear a difference anyway, but if you insist on your goal of splitting a 192 kHz 24 bit hir-res signal between mains and subs, this setup is not right for you.

In relation to this I wonder why only the input resolution is shown on the WHA and Ultra display. There should be a similar display of outgoing resolution @WiiM Team

When I group my WiiM Amp Plus and my WiiM Amp Pro the app shows the actually used bit depth and sampling rate for me. In the case of the WHA integrated Tidal client this is 16 bit 44.1 kHz. Amazon Music has been reported to be supported up to 24 bit 48 kHz with grouped devices.

Does it also show the correct resolution on the leader, if also outputting sound.

The follower show what is provided by the network. But as I understand it, the leader will also be outputting with the same resolution as used for the link.

Let me check this instantly.

WiiM Amp Ultra as leader, WiiM Amp Pro as follower, since only the Ultra has a screen. As soon as the devices are grouped there are no individual Now Playing screens in the app any more. There's just one unified screen for the group.

Step 1: Playing a Tidal MAX file through the WiiM Amp Ultra. I didn't take pictures of the touchscreen display, but it showed exactly the same data.


Step 2: Group the WiiM Amp Pro with the WiiM Amp Ultra with the Pro becoming the follower. Again, the exactly same data rate was shown on the touchscreen display.


Step 3: Pulling down the Now Playing screen reveals the view on the current album view from the Tidal client integrated into the WiiM Home app. Note that the source is still correctly displayed as MAX while the Now Playing screen displayed the reduced data rate.


This is clear enough for me.

Sorry, but I didn't skip anything. I had to listen to the entire album. Still three songs till I can finally go to sleep.

Ok, I see, thank you for the info! Now it is clear !

see the leader board at https://forum.wiimhome.com/members/

Thank you, didn't know about this board.

Yes, it helps thank you. In grouped mode it is always 48kHz

You didn't accept as a proof the numbers you've been given because you didn't like them.

No, I accepted them after proofs. Now I see it was correct.

The first bullet point reads "Multiroom of Hi-Res Audio".

That will be great, because I thought to use two WiiMs in Hi-Res setup. So, we should wait again, whole life is about wating for smth. hmm...

Is it so hard to see that we just want to protect you from a disappointment?

No no, you all axactly faced me with this disappointment, showing me low-res of multi room mode )))

When I group my WiiM Amp Plus and my WiiM Amp Pro the app shows the actually used bit depth and sampling rate for me.

This is what another member pointes as mistake, but anyway "I see the bitrate on my DAC". I just don't controll it constantly.

But we started this discussion speaking about LP/HP filters guys. It is still no possibility to adjust the "order" of filters, they both have only fix 4th order. I would like to set more rapid curve, if it suitable with possiblities of WiiM Chips.

I don't see hi-res multi-room music coming any time soon, though. Very few ask for it and it's been on the roadmap far too long, never making it into any other category than "maybe in the future".

I don't see this coming either. The filter slope isn't even adjustable so far on those WiiM products offering a proper subwoofer management. 4th order LR is actually steep enough for most all applications. Steeper filter slopes usually also means higher group delay.

PS:
If you still want to catch WiiM's attention for these topics it's best to send them feedback through the WiiM Home app.

In the same support ticket I posted earlier (I can provide a copy if required ) WiiM said their next step is likely to be 24/48 multiroom rather than 16/48 so upping the sample rate looks even further into the future.

Yet they can’t even get DLNA Casting to work properly with lossy 320 K MP3.

It is pity to hear.. Very few people think to use group mode not for multi-room..

I don't see this coming either. The filter slope isn't even adjustable so far on those WiiM products offering a proper subwoofer management.

I see, this could be the first nessesary step for future updates. Again, if somebody ask this.. but not me, I don't have Ultra.

Steeper filter slopes usually also means higher group delay.

Ahaa.. Ok I undestand, this could be more difficult task for chip.

Overall, two WiiMs may be not the best Idea to set bi-dac-amping in Hi-Res with active filters. I will look for smth. else. Thank guys for your help here !
