Room correction

[Franco81]

Hi! Any advice on room correction. I am a happy owner of the Wiim Ultra. As a total inexperienced person, I tried to take a measurement with my Samsung smartphone with the default values of the Wiim home app and the result is what you see...if I understood correctly, the white line is my room...how does it look? The value of the high frequencies seems very excessive to me at 8k. I don't think my system is that unbalanced on high frequencies. My advice: I would like to get an external microphone and I read a lot about the Dayton Imm6. Is there a difference if I choose Jack or USB-C? Are both okay?

Please do a search on that topic - all answers are there…

I have such a microphone and I recommend it.
The parameters of microphones in phones are too different. Unfortunately, RC in Wiim does not install calibration of measuring microphones yet. Despite this, they are quite accurate with default RC settings.
I use Dayton IMM-6C with iPhone and Housecurve application. From there I copy correction settings to Wiim after measurements.
It works well.

So you measure how?
Play something through the WiiM, then measure it with mic and your Iphone with an app, then put the resulst by hand in the WiiM EQ?
if so why this way and not using the inbuild room correction function?

Because there is not a standard calibrated mic across all phones or tablets. Even in the Apple ecosystem, although some generations of iPhones are "good enough" in producing predictable results, many are not.

In other words, if I use, say a Pixel, Samsung, and iPhone to measure the frequency response of my speakers in my room using the WHA, I will get three significantly different results, and therefore the room correction changes will be different (and they can't all be right, i.e. GIGO). Only if you use devices that are calibrated against an established standard which a room correction solution can use for metrics will you get objectively reproducible results. And at this point, apparently WHA does not yet support using something like a precision UMIK mic to sample a room's auditory characteristics.

WiiM room correction does support the use of external mics like the Dayton Imm-6c (don’t know if anyone has tried a UMIK mic) on either iOS or Android, and as has been discussed before if the calibration file shows less than 1db variation over the default 40-4000Hz range, then the lack of applying a calibration file isn’t significant.

WiiM are now promoting the use of room correction over the full frequency range which will make calibration files much more important.
