Updated WiiM Ultra and Amp Ultra Roadmaps Are Here

We just published an updated roadmap for the WiiM Ultra and the WiiM Amp Ultra, and we’ll be updating some other roadmaps soon. You can see the full details on our Help Center (Ultra| Amp Ultra), but here are some highlights and a quick look at where we're headed.

What This Roadmap Represents​

This is a transparent look at what we're actively building, what we're exploring, and what we've recently shipped. Some of these features will land exactly as described. Others might evolve as we work through technical realities and a few might not make it at all. You’ll also notice that there are no timelines, development is a long process and priorities shift throughout the year, so we’re not going to commit to specific timing right now.

We're sharing this openly because your feedback directly shapes our priorities. We watch all the forum conversations, app surveys, and feature requests you share, and use it all to feed into this. So check it out, and we hope there’s something in here you love the idea of!

These roadmaps focus on the Ultra and Amp Ultra first. They're our flagship devices with the hardware to support more advanced features. Where it makes sense and where it's technically feasible, we'll bring capabilities to other products in the lineup. Some features will be Ultra-specific by necessity.

What's Next​

Display & Interface Upgrades

Input-specific screen layouts that remember your preferences and automatically switch based on active input. Black background mode for album art that blends seamlessly with the bezel. Standby and clock options including permanent clock display during playback with adjustable timeout durations. Direct USB and Favorites browsing on the touchscreen without needing your phone.

Next-Generation Room Correction

BassFit integration automatically aligns time and level between your main speakers and subwoofer for seamless low-end coherence. SurroundFit calibration provides precise automated alignment of front, surround, and subwoofer channels for immersive experiences. RoomFit+ evolution delivers tighter bass response and improved transient handling. CenterFit phantom center creates adjustable vocal enhancement for improved dialogue clarity. Context-aware bass management assigns independent crossover and gain settings per source. Discrete dual subwoofer control enables independent calibration to smooth out room modes.

Smarter Audio Processing

Scenario-based presets for Night, Dialog, and Sports modes powered by our 10-band PEQ engine. Adaptive dynamic loudness using Fletcher-Munson curves to preserve bass and treble at low volumes. Pro-grade filter import from REW or AutoEQ. Advanced profile management for transferring correction data across devices with Expert Mode for weighted measurements.



Connectivity & Ecosystem

Adaptive source profiles let you customize EQ curves, volume, display layouts, and grouping logic per input that automatically engage when you switch sources. Universal hi-res multi-room with expanded support across Roon Ready and Google Cast endpoints. NAS Mode (SMB Write) transforms the devices into network music servers, managing and transferring files to your USB drive wirelessly. Native Plex integration with Plex control. Complete overhaul of the internet radio engine for faster buffering and higher bitrate streams. Expanded wireless subwoofer protocol to Roon and Google Cast. Support for USB libraries up to 200,000 tracks.

Smart Home Integration

Deeper Home Assistant integration with support for presets and alarms. Native Apple HomeKit and Shortcuts support. Smart input switching that preserves playback context and volume states.

Future Concepts Under Consideration

Specialized streaming integrations for Idagio (Classical), Nugs.net (Live Events), and SiriusXM. Personal cloud locker support for Dropbox, OneDrive, and iCloud, allowing you to stream your collection directly without a physical NAS or USB drive.

What We've Already Delivered​

Visual personalization with new VU meter styles, dynamic music spectrums, and expanded clock faces. Native WiiM Home App on Apple TV, Google TV, and FireTV. On-glass navigation for local radio and recently played tracks. Home screen widgets for iOS and Android. Precision volume with customizable remote steps. Multi-point room calibration. Per-output EQ. Advanced DAC filter settings with user-selectable interpolation filters (Amp Ultra).

Flexible wireless home theater supporting scalable 4.0, 4.1, and 5.1 channel configurations. Smart presets that trigger complex routines—setting input, volume, EQ, and grouping simultaneously. Persistent grouping for fixed speaker zones. Native YouTube Music support. Completely rewritten USB media engine.

Your Suggestions!​

These roadmaps are a starting point. We're watching your responses, reading the threads, and paying attention to what resonates. If there's a feature you're interested in, say so. If something doesn't make sense for your use case, let us know, but be respectful. Not every feature is going to hit for every person, a feature you’ll never use might be exactly what someone else needs.

We're building this with you, not for you. The difference matters.

Check out the full roadmaps (Ultra | Amp Ultra).

Can grouping be made source dependent?

From the roadmap for the Amp Ultra. Perhaps this may help you?

• Adaptive Source Profiles: Customize your listening environment per input. Assign unique EQ curves, volume, display layouts, play duration, contents (if applicable), and grouping logic that automatically engage when you switch sources.

I miss traditional bass and treble controls; the pre-programmed presets don't quite work for me, and setting them up sensibly isn't easy either; the more sliders, the more difficult. The built-in graphic equalizer always reminds me of cheap amplifiers and boomboxes; better amps have bass and treble controls, or none at all. There's also a parametric equalizer, but to use it properly, you probably need a degree in that field.

Old school style?
(I suggested it might be fun to have an audio interface that mimics the look of an old integrated amp from the 70s...with direct access to all those "return" audio functions after years of neglect.
common approaches of interfaces in the "professional" world.... adopting the visual codes of the hardware.
)
;-)

Can grouping be made source dependent?

Eg. I'm streaming Spotify music to my TV and kitchen speakers grouped together. Then I switch to HDMI on my TV speakers and they remain grouped which is annoying because when grouped they don't lipsync to the video, and so I have to manually ungroup.

I'm not sure if I fully understand your issue, but please create a persistent group with the kitchen as the leader. You play Spotify to the persistent group, then switching the TV(follower device) input to HDMI will automatically release the group.

Additionally, the Input Sound Profile feature currently available in Ultra's beta firmware will soon allow you to link inputs with group configurations.

A feature that I would like to see added this year is DLNA Casting from every compatible WiiM device.

There was a Beta Test: DLNA Cast way back in June 2024, but this has never worked properly, and seems to have been abandoned since.

The Ultra firmware does have a non working "DLNA Out" listed under the Audio Output section, and this should either be made workable, or removed altogether.

There are still Beta firmware versions listed for the Pro, Pro Plus, and Amp, all dated 22nd January 2025, but these don't work either.

I think WiiM have forgotten that this was priority number one when Airplay disappeared

 

[QuarryHunslet]

Yes, they certainly seem to have done. All I am asking for is a like for like alternative replacement for it.

 

[dankandi]

for the WAU screen, i know it is not OLED, but the current clock face has too much light leakage.

I wonder if you can use a different font color, so as to reduce the white light needed by the LCD.

Perhaps use the darker silver/grey of the enclosure, and not pure white for fonts

 

[90sNintendoKid]

One of the reasons I stopped using my Wiim Ultra for EQ was because I couldn't independently set the delay between the left and right speakers and sub out.

I noticed that Bassfit and Roomfit are being updated.

Would I be able to independently delay my left and right speakers if I don't use any of the Wiim room correction methods?

Also you mention dual subwoofer alignment, my guess is that would be for the Wiim Sub.

 

[harkpabst]

... better amps have bass and treble controls, or none at all.

No, that's certainly not a valid way to judge an amplifier's quality.

The most useful tone control I ever found in any sort of audio gear to this day is Quad's tilt and bass lift. I'm happy to still own my Quads, but don't currently use them. If I had to choose between an amp having either only this ingenious tone control or only RoomFit and a 10 band PEQ, personally I'd always go with the latter.

I currently have my WiiM ultra eq setup the quad way
It works really well adding just a touch of warmth

My Quad 44/405-2 have been silent for well over 20 years, but I still have them.

I never had the pleasure of owning one but I used to sell them back in the 70s quad 33 and 303 mainly
Could never afford one back then

 

[harkpabst]

Does one "prevent" the other? ;-)

No, of course not. Did anybod say so? I made a very simplistic thought experiment, indicated by the pretty clear introduction "if I had to choose between ...". ;-)

I explicitly didn't say "one has to choose between ...".

Used to have a 33 and 303 back in the day.

 

[harkpabst]

We're distracting a bit from the topic of this thread and I feel guilty of having fuelled this distraction.

So let me make this very clear: Asking for bass and treble controls (or maybe even a mid control, as found e.g. in many classic Marantz amps) is a perfectly valid feature request. It wasn't my intention to talk this down.

As such, it could be posted in the feature requests sub-forum. There's just no guarantee if many owners will upvote it.

A lot of the items on the roadmap sound very interesting - I'm looking forward to see how this develops!

@RyanWithWiiM @WiiM Team Do you mind if I ask a few questions on some of them?

BassFit integration automatically aligns time and level between your main speakers and subwoofer for seamless low-end coherence.

Is this an evolution of the current automatic subwoofer and loudspeaker sync function; and if so, will it now use the phone built-in mic / external mic (i.e. like RoomFit), instead of the WiiM device built-in mic?

SurroundFit calibration provides precise automated alignment of front, surround, and subwoofer channels for immersive experiences.

Is this just alignment (i.e. relative channel delay adjustment) or will it also include frequency response correction filters (i.e. like RoomFit, but for 5.1 layout)?
At the moment EQ and RoomFit don't seem to work when Dolby 5.1 content is played - which is IMO very unfortunate.

RoomFit+ evolution delivers tighter bass response and improved transient handling.

Does this mean you are considering adding phase response correction to RoomFit (e.g. like in Dirac Live or Audiolense, which can e.g. remove crossover phase wraps)?
Will this be optional and configurable?

Discrete dual subwoofer control enables independent calibration to smooth out room modes.

Does this mean stereo bass (where one subwoofer plays left channel bass and the second one plays the right channel bass), or that we will be able to use both subwoofers in mono (L+R) configuration to optimize bass response over several seats (like you can do with Multi-Sub Optimizer or with Dirac Live Bass Control module)?
Will this only be possible with 2x WiiM Sub Pro, or will other solutions be possible as well?

E.g. a very interesting option would be to be able to use a dedicated WiiM Mini driving just one (or both) non-WiiM wired subs with content below the crossover, and paired with a master WiiM device which is driving the main loudspeakers with content above the crossover.
That would open a lot of possible configurations and flexibility.

Adaptive dynamic loudness using Fletcher-Munson curves to preserve bass and treble at low volumes.

Note that the Fletcher-Munson curves are a very old variant of equal-loudness contours. The most recent version is defined in ISO 226:2023, so I'd recommend to use those as a baseline for the dynamic loudness feature.

If we normalize ISO 226:2023 curves (e.g. to the 80 phon curve, as that is close to a standard monitoring level used for audio production), we can see that there's not much change to treble level between individual curves (and what there is happens mainly at very high frequencies and at very low levels), but that there's significant difference in bass level between them:

(Source: ISO 226 curves were traced from this article with WebPlotDigitizer, and normalized in REW to the 80 phon curve)

Given all this, it is my opinion that a dynamic loudness feature should mainly adjust bass amount, and that treble adjustment should be minimal (though I personally believe treble adjustment is not really needed at all).

Lastly, this kind of feature needs to have a calibration function, so that the user can adjust the reference point to match their own listening distance, preamp/amplifier gain and loudspeaker sensitivity.
Unfortunately, no generic reference setting will match every environment.

Expert Mode for weighted measurements

This sounds very interesting, but I have no idea what it might mean. Could you give us some hints?

Thanks for all the great work so far!
