Why is everything so complicated?

Probably. I have iMM-6C USB-C microphone. So I need to find an adapter: Line out to USB-A, to connect it to my PC. Will the microphone be correctly recognized by REW then?

You just need a USB-A to USB-C cable don't you. The cable included with my UMIK-1 is USB-A to USB-C. When I use it with my phone I used the USB-A to USB-C adapter that came with the phone.

Why do you think this has anything to do with the phone?

The RoomFit calculations are not done by the WiiM Home App on the phone.

If you use a USB microphone the ADC is done by the microphone and the test sweeps just forwarded by the app to the WiiM servers.

It's definitely a problem with the phone.

There is some filtering going on that cannot be fully controlled by non-system apps. WiiM did confirm and address this issue. They made some improvements but in the end the result with some phones remains unusable even with external mics.

So far it looks like this might mostly affect Mediatek SoCs, but we don't have enough data points to confirm this.

Yes. I have just looked this up and strange enough it looks like it's some phones like the Galaxy Note that cuts the low frequency even when called like:

AudioRecord recorder = new AudioRecord(MediaRecorder.AudioSource.UNPROCESSED,
sampleRate,
channelConfig,
audioFormat,
bufferSize
);
