What does that mean? Which recording quality is it based on?

Does it automatically limit the low-frequency range when using the built-in microphone?

Nice option but where did you found it? On android and iOS I can't see that option.

Cannot find that where is it located or does it need a firmware update?

It is for the Sound only?

Yes, as said in the release note

Do you have the WiiM Sound? If not, it doesn’t apply to your devices.

Kind of dynamic loudness feature. Don’t know why only for Sound devices. I would be very happy to test it on my Ultra as it is one of anticipated new functions for me.

Changed is and it. Senior moment . But even better I had used ! instead ?

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.

I'm having trouble translating...

Does a bass boost proportionally decrease the overall level?
(Really typical risq of saturations ..)

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

I always save screenshots, so it was extremely frustrating.

I recommend using a USB cable

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.
