Completed Beta: Room Correction for Android

[mrroyal88]

Can anyone help me. When i did the room correction, can you switch between b&k/harman/ flat or does it require to do the room correction again with the wanted curve? Would be nice to switch afterwards..

Please create 3 custom PEQs with 3 different curves and switch PEQs.

In other words, run RC three times with different curves and save each one.

Ok that makes sense, thank you !

What do you guys set the max gain to, and does it even make a difference when executing the RC?

No hard and sound rules. 10 dB is definitely on the high side. If you boost any frequency by 10 dB the amp will have to crank out 10 times the power compared to no correction applied. Personally I would rather stick with something like 6 dB but it really all depends on your room, your speakers and your power amp.

So, where are we now with mic compatibility (wanting to buy a Dayton Audio iMM-6C, for use with a Samsung Galaxy S23)?

The IMM-6C connected to the usb-c of my gallery tab S8+ is recognized by the WIIM app and can be used in RC.

Ok ill try that out !

I would just buy a second hand umik. Ive done that and all i can say is it sounds really good. Sure people with rew and dirac live will have much better but the software has its limits.

Does the WiiM actually identify the Dayton mic--or does WHA just use whatever mic the phone itself connects to?

I have an older IMM-6 TRRS that I was hoping to use with an adapter dongle to my S23. Now you have me wondering if it might not be recognized.

 

[mrroyal88]

It might work but ive seen users claim that the dongle adds distortion to the mic. There is a reason why they made a usb c version i guess

Yes, WHA Identifying IMM-6C.

Just turn the fan off so it doesn't blow the sound around while you are measuring ;) Glad to see you've dipped your toes in the water. Can't wait to see how you describe your 'now listening' posts!! 😃😊👍

I also have an IMM-6, but could not use it with my dongle.
Look for past posts about available dongles. I believe someone mentioned that the old Google dongle was available.

I tested both imm6c and imm6 (using an apple dongle). I found the results very similar, however out of three different manufacturer dongles only the Apple dongle worked. others would not register the imm6 in Wimm room correction through the 3.5mm jack. I tested a variety of devices.. Samsung s23, Samsung s10e and Samsung tablets S10 S8 S2.
I ended up keeping the imm6c as leaving the dongle out of the equation and going straight into the phone seemed to make the most sense logically.

Thanks for the great info.

I remember testing two dongles with LG, Samsung and Xiaomi. Probably most of the commercial products are unusable.

Didn't the imm6C calibration file have larger corrections at low frequency than that of the iMM6.

No problem with using an IMM-6C with my Samsung S22.

I downloaded the calibration file for my IMM-6C and every frequency under 9.5KHz was within 0.5 dB. Now I realize each calibration file is unique to its own microphone so some may vary more than mine but for me to think I need more precision than what my IMM-6C provides for a home setup would be delusional in my opinion.

I was thinking of this post

Do these inexpensive mics have internal active correction (DSP)?
My B&K and PCB mics have smoother response, but still spec at similar ±1dB over similar frequency range. At >$1000 each.

I'd rather believe this is how it's accomplished so cheaply, and trust Dayton and MiniDSP--rather than believe their graphs are complete rubbish.
