RoomFit high frequency measurements problem

[KolegaPaweł]

Hi, I tried to do some measurements today and noticed weird RoomFit behavior. On graph it shows high frequency almost not existing at all. I'm in age where I can easily hear 15-16khz and I didn't notice any difference in tweeter's performance. I did measurements with umik-1 microphone and my smartphone and both shows the same. I have b&w 706 S3 speakers witch are very bright so it is weird.
Few months before measurements looked like that:

And now they look like this:

I almost sure nothing happened to my tweeter's. It is the same room same setting same everything. I've done a lot of measurements some time ago and weird behavior like that happend sometimes but it was single accidents. I tried turning volume up and down, tried different calibration file for umik 1 and did measurement about 5 times with the same results. Anyone have idea what is going on? Should I send my wiim to warranty?

Edit: I did rew measurement and it came out good:

IMHO such a sharp drop in response + response ending up below -60dB suggests some kind of SW problem, rather that a HW issue.

It is difficult to say if the issue in on the phone side or on WiiM side, so I'd suggest to open a support ticket describing this issue via the WiiM Home app > More > Feedback and Tickets function. This will transfer the logs to them to help with analysis.

I agree with @dominikz's suggestion.

This is just my speculation, perhaps due to some error, the RoomFit test audio isn't playing correctly. However, based on what I've checked so far, I haven't observed any issues with RoomFit itself. (RoomFit runs on WiiM's server, not on WiiM devices.)

Is this a sweep? What happens if you turn on MMM and measure with pink noise?

Also, while unlikely, there may be an issue with your phone, so please try rebooting it. If you have another phone or tablet, please try using that instead.

I have rebooted all devices nothing changed. If you ask about rew measurement yes it is a sweep. I don't know what MMM is, it is in rew or RoomFit? This rew measurement is consistent with previous measurements. Unfortunately and don't have any other device to test it but it is the same device I measured with few months ago and it was ok.

Enabling 'Moving Mic Measurement (Beta)' in RoomFit allows you to measure using pink noise. If the high frequencies are not cut during pink noise measurement, there is likely an issue with the playback of RoomFit's test sweep.
