RoomFit Moving Mic Measurement (beta) - improvements

[Wiimer]

Did I read somewhere that you could turn off the rotation of the phone when using a USB microphone? I just tried MMM and couldn't find a way to turn it off.

Yeah, I just checked and the button was gone...

Today I tried RoomFit Moving Mic Measurement (beta) with the latest improvements on my Amp Ultra, using an iPhone 17 with an external UMIK-1 microphone.
The instructions in WHA say to point the microphone upward.
I’m wondering whether I should use the normal calibration file or the 90-degree one?

90
(Just for that reason...with calibrated microphones without a 90-degree angle, stick to "low frequency" measurements in this situation)

I just pointed the mic towards the speakers. If you do point it upwards use the 90 degree cal file.

I wonder why WiiM advice to point it upwards... Why did you point instead the mic towards the speakers?

I always point the mic towards the speakers. I suppose it depends on the area you want to cover with the moving microphone. I just moved a metre sideways between the speakers.

Have a look at this post:

Have a look at this explanation, and these examples.

But note that either orientation is actually equally OK in room correction context - as long as you use the correct calibration file (90° cal for vertical orientation, 0° cal for horizontal orientation).

Hey... I'd be curious to know how the Dayton behaves at 90 degrees...?
Could you make a precise observation from 70cm center of the tweeter and then again at 90 degrees, fairly accurately, in the same spot?
And what about its behavior above 2kHz in particular?
;-)
