Room correction and different devices

[andyp]

I just wanna share the difference between measuring with iPhone vs Macbook Air.

Buchardt audio s400 mk2
Nad c3050
Q-acoustics 3060 sub
4m x 10m room.

iPhone:
Pic 1-3

Macbook
Pic 4-6

Dont know what to make of it really.

My question would be, which device have the best mic and therefor would be most accurate.
My devices: iPhone 11, old iPad, Macbook air m3.

Or maybe doesnt matter, all mics are pretty much the same.

You have no way of knowing unless you have a calibrated microphone and then seeing which of those two are closest to the calibrated mic.
