Beta Test: Room Correction for Android (Feature now publicly available)

[Wiimer]

OK that makes sense. Does the WiiM app tell you it is using the built-in mic?

Where is such an indication?
I may have missed it.

I think it appears on the screen before you perform the measurement. I tried the Spectroid app and that recognises the iMM6 as well.

OK, Thanks.

Mine is the same as yours.
WHA always shows "built-in microphone".

And apparently the IMM-6C is not recognized either.
Perhaps the external microphone is not yet available on Android RC.


1. Built-in mic




2. IMM-6C



Therefore, I use the built-in microphone in future tests.

I thought they were waiting for external mics to be supported before releasing the Android version. I have also reported the failure to recognise the iMM6.

Yes, I was expecting the external mic and RC per channel to come at the same time, but I guess my expectations were too much. But we are just getting started.

After a quick bug check, I ran RC with the Xiaomi 12T pro's built-in mic.
(Speaker is Focal chorus 716)

1. First I look at room noise.


2. RC result.




This is a comparison of the frequency response before and after RC, with Spotify playing a 20Hz-20kHz tone signal. As mentioned above, setting the target curve flat does not make it flat.

A. Before RC


B. After RC








When I played some of the tracks, the bass was too strong. So I adjusted it this way and will listen to it for the next few hours.



My brief impression is that I am surprised that the sound is better than expected. I think it is promising as an auxiliary tool for room correction, although it is not ideal at present.

Next, I will check to see if I can get the same results with other Android devices.

I noticed that flat didn't seem to work then trying again later it did.

As you said, it flattened out in the WiiM amp. Perhaps it is an Ultra only issue.

IMM-6 mic retest.

2. Measured with LG V60 + IMM-6 mic

When I compare the built-in mic to the IMM-6, the RC results match, but the measurement app does not. Thus, at least the WiiM app on my V60 phone does not recognize the IMM-6. However, the IMM-6 is not picking up the bass, so perhaps there is a problem with the V60 as well. (I don't know the cause due to my lack of knowledge.)

I will ask about this on the ticket.
(Ticket No.507687)

What do you mean "not picking up the bass"?. I see both measuring to 40hz as expected.

My ARC USB mic was recognized just fine

Please compare the second and fourth pictures, the Sound Analyzer Pro app has less bass when measured with the IMM-6. However, this is most likely a problem with the app settings or the phone, so please forget it.

@Wiimer tried the iMM6C and the original iMM6 and neither one was recognised. I don't think I know the ARC USB mic, do you have a link?

It was included as part of the Anthem Room Correction component of the Paradigm PW-Link streamer. I would opt for a Umik-1 if I were just buying a USB mic.

 

[onlyoneme]

Not sure if someone had confirmed it already but umik-1 works ok.

The UK price for the umik-1 is close to double the US price.

Well, I don't know, you are probably right. I do not try to convince anyone to buy it, I was just curious if my mic works.

 

[Brantome]

Are you sure you’re not comparing the umik-1 to umik-2? The GBP and USD figures aren’t far apart for each model

 

[jmudrick]

When I noticed yesterday evening that a Beta is available I checked it with my S24 and my UMIK 1 for curiosity only (I am weak, I know), there is no intention to use the RC feature. It worked and the mic was found. It was also found weeks ago in the iOS app.

It would be useful for the beta if you could measure even if you don't implement the correction. Take one for the team, takes about 20 seconds

 

[Brantome]

I am back on normal already, sorry.

And working on a Saturday? I’d have a word with your union

 

[jmudrick]

And, by the way, can you imagine me showing a graph?

Get a 6 year old to help you with a screenshot...

Maybe the price at miniDSP doesn't include taxes and shipping. Over £100 always puts me off
