WiiM Home App v3.3.9 Update – Oct 24, 2025

Please review the app update release notes below. If you encounter any issues, feel free to reach out to us.

* The iOS app is available on the App Store, while the Android app is currently under review by Google Play.

What's New:

1. WiiM Sound:

- RoomFit™ room correction available during first-time setup (OOBE).
- In-app user manual.
- Dynamic Bass control.
2. Playback & Display: Audio Spectrum option on WiiM Ultra Now Playing screen (requires upcoming beta firmware).
3. Alarms: Custom labels and support for up to 32 alarms (requires upcoming firmware).
4. RoomFit: Automatically adjusts measurement range based on recording quality.
5. HDMI ARC: On-screen prompt when an unsupported audio format is detected via ARC.
 
What does that mean? Which recording quality is it based on?
As far as I can ascertain, it appears to be an automatic restriction when using the built-in microphone.

3.3.8

3.3.9

Both were run at 20Hz-4kHz, but in 3.3.9 the minimum correction frequency was restricted to 60Hz.

Btw, in 3.3.9 the RoomFit screen has stopped rotating again! 😊
Please, for goodness' sake, don't ever rotate again 😂

Actually with Dayton mic directly attached to my phone auto rotating was very helpful. For me it is no good if this feature was reverted. But simply option to turn it on/off should do the job.

Yeah, agree. Making it optional would have satisfied everyone.

I always save screenshots, so it was extremely frustrating.

I recommend using a USB cable 🙂
 
I'm having trouble translating...
:oops:
Does a bass boost proportionally decrease the overall level?
(Typical risq of saturations)
From the description I'd say the opposite - when you decrease volume the bass is probably gradually boosted. Presumably this is intended to compensate for human hearing non-linearity at low frequencies (i.e. equal-loudness contours).

There should therefore be no risk of overload, since boost is presumably only applied when volume is reduced, and the most boost would therefore be added with the lowest output volume.

My interpretation of the function could be wrong, however!
 
Does it automatically limit the low-frequency range when using the built-in microphone?
Hi @Wiimer ,

Your understanding is correct. Due to the built-in microphone’s limited sensitivity in the low-frequency range, its recordings cannot be used for RoomFit™. We’ve updated the algorithm to handle this condition and provide more accurate correction results.
