Room correction

[Burnside]

Hello. Is it possible to import EQ settings from Eq APO?

Same response as last time you asked - no.

RC is not working for me properly anymore. Even if I strongly hear my sub when listening music, it doesnt show up on RC screen when doing correction. I turned volume up, and still no changes.

In the past, the measured subwoofer signal was even higher than the expected signal after correction, and I had to reduce gain.

Its like I have subwoofer calibration OFF, even if its ON in the settings.

Any idea what Im doing wrong here?

Your phone is Xiaomi/Redmi/Poco?

 

[sNc]

Yes. POCO X7 pro. But I use external Mic.

With mic or without mic - doesnt matter. With calibration file or without - doesnt matter.

Had the same issue with Poco X6 Pro and imm 6c with cal file. Results from these phones are almost useless for meaningful eq

But how this is possible if Im using external mic? Btw I have the same mic as you

When I had Xiaomi 9T, everything was fine

Somehow phone manages to perform some internal eq on digital audio stream from mic

What's the point of buying any external microphone connected to a phone if you can't trust these measurements!?!?!

Can it be like this because I have subwoofer bypass mode turned ON? So during music listening I hear everything properly, but during RC the app is deciding to not take into consideration sub signal? I'm at work and just figured out that I dont remember if this function was before - when I was originally doing RIC for the first time

It is not caused by sub settings in wiim home app, check frequency response of whole system via REW

Ask Poco if they mess with the response of USB microphones.

A good test is to also consider, if you have an alternative device to try, like a tablet or an Android-based DAP, to install WiiM Home App on an alternative device, plug the external mic into the other device and try running room correction on the other device to see if you get the same results.

Hello, wiim fans. New instrument for DRC, meashurement and generate filter tool - Cavern EQ.
See export option

RC set up for 30-600. All measurements with external mic

First one: redmi note 14 pro, second: Poco X7 pro. Both are incorrect... Why? THe bass is strong when listening music

The previous: redmi 9t pro - different from these two.

This is fcked up

I cant run RC to get proper results, and I dont have my old phone anymore.

Im doing something wrong = there were some changes, and I dont know how to adjust RC to see it properly, or I dont know what is happening.

Definitely looks wrong. Does the response change if you turn off the sub?

Room correction is currently available only on iOS devices, uses the IOS device's built-in microphone to measure the test tone played by the WiiM. Based on the results of that measurement, the function automatically adjusts the PEQ so that the frequency response is basically flat.

Room correction on Android devices will be added in a future update.

I (think I) know the reason for this is the better mics in iPhones. Any iPhone users who also have a miniDSP UMIK-1 who can compare the two? Is it a night and day difference or just an smaller incremental upgrade?

This quoted post from Mr. @Wiimer is from the middle of 2024. Many things happened in between.

Massive difference between my UMIK-1 and my iPhone 16 Pro’s mic.

A little. The fact that there are differences between the two phones with same external mic, where RCs settings are exactly the same, shows that it strongly depends on what low-pass filters have the latest Androids? Sure, they are there to reduce noise... but that makes them totally useless for RC purpose. Ofc if thats the reason.

@WiiM Support
Why can't the Wiim app force Android to get a clean full signal, by omitting these low-pass filters built in phone software?

Does the Room Correction report that it is using the external USB microphone?

Maybe there is an App that forces the Android to not using the low pass filter?
(It is not the task of WiiM to care for the devices outside of WiiM…)
