Room correction and mic practice

[Fralle]

As this person points out, there are many questions that Wiim isn't very specific about:

Should I use the main microphone located at the bottom of my Android phone or the one at the top? Is it "better" to use iOS or Android? Would an iPad (although I'm not sure where the microphone is located on the 9th generation) have better microphones than an iPhone or Android phone? How far should you hold the device from your head?

If I buy an external microphone like the Dayton Audio IMM-6, would that improve things significantly? I'm not very keen on going through the whole calibration process since reading about it gives me a mild migraine.

Android phones are many and various, so you're better sticking to a known quantity like the Dayton Audio Imm-6 but make sure you get the right version for your phone - usb-c or TRRS.

It's a relatively small investment for better results - even without the ability to load the calibration file. See https://forum.wiimhome.com/posts/77706/

 

[Fralle]

Thank you! And TRRS is that the one with a regular 3.5 for headpone jacks?

yeah, the 3.5mm socket

 

[Fralle]

So even without the calibration file you think this will give me better resaults than just usinng an ipad or android?

Yeah - I agree with the opinion in the link I provided in comment #2

Witch target curve are you using ? (Flat, Harman, B&K... ), wich freq. response ? and witch gain ? 0 to 10 dB... This is an interesting software, but there´s not a lot of info how to configure it... a compreensive tutorial would help...

 

[Fralle]

Actually I had no idea you had to select gain etc. Total newbie and I thougt this was gonna be easy

You don't "need" to set gain. You can leave it at default at first. You need to experiment to find out what works best for you.

Yes, but some people say 10dB is to much...that should be 3 or 4 dB max...and that frq. response sould be 300 to 400 Hz...otherwise we will be changing to much of the speakers" own" sound...

10dB is the maximum, it doesn't necessarily mean it will use 10dB. Nothing is set in stone. Try different things.

You also risk severe distortion if your amp can't handle the power requirements.

Where can I find and run full sound spectrum to run, to make a measurement? I have micro i6MMc + AudioTool app

REW lets you download sweeps or pink noise. Use the generator function. Why not try the WiiM RC as well to compare?

Definitely something to keep in mind.

I will compare, thanks

An interesting comparison - since purchasing the WiiM Ultra I compared the result of a room correction sweep using my iPhone 13 Pro (without case) with my existing digital room correction using an Earthworks M23. Both measurements taken at the listening position, as used for speaker/sub DEQX time alignment.

The resulting WiiM Parametric EQ tracks (surprisingly) accurately against the in-room frequency peaks and nulls as already detected by the ~£700 Calibrated mic. (range chosen for WiiM 40-3,500hz, my speakers are already corrected via M23 at 10-22,000hz). Even the Q parameters broadly matched the widths of larger peaks and nulls.

I find this both impressive and reassuring... although I have no need for further EQ correction it suggests that even an iPhone mic can do a pretty reasonable job with the lower-middle frequencies and all credit to WiiM for developing this simple to use feature.

Thanks very much for that practical feedback!
