Agressive Noice Reduction / Microphone Sensitivity Issue - Xiaomi Redmi 4X Questions & Answers

Is there any way to disable the noice reduction?
Or any values to change to make it less active / agressive?
Whenever I record my guitar by connecting a lapel mic to the phone or earphone's mic then I get this weird recording like I recorded it under water
I just invested in that Lapel Mic and i get to know that it doesn't help in any way
So please I request that someone to help me out with this and provide me any fixes for this issue
Thanks.

Thats great but this is not the hardware problem
It's a software bug
So there should be a way to fix it
I just need that fix
I don't need a Bluetooth Receiver because I can record the audio in RAW that disables the secondary noice cancellation microphone totally that give another problem of a hissing sound just like when a mic is directly plugged into a DSLR camera

@amanu247 there has been written a lot about this issue. Also on Xda.
You need root.
It is the ACDB profile in combination with fluence. The short version:
edit /etc/audio_platform_info.xml and search section <acdb_ids>
and add or change these lines:
Code:
<device name="SND_DEVICE_IN_VOICE_DMIC" acdb_id="41"/>
<device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="4"/>
<device name="SND_DEVICE_IN_HANDSET_STEREO_DMIC" acdb_id="21"/>
If that doesn't work you may want to add this line to /system/build.prop
persist.audio.fluence.audiorec=false
Cheers

Bluetooth Microphone only?

I wonder if any of you know the existance of a bluetooth microphone so I can record a class. I love to be able to leave the mic close to the instructor desk and be able to record with better quality.
I am using my mogul to record with the external mic and it's fairly good for the distance btw the device and the speaker, but I have to do some audio editing in order to hear a clear sound.
Anyone? or maybe another solution for this?
Thanks

[REQ]Live listener app

So... I have HTC A300 and I can add external microphone (I have powerful one) to my Pro. What I want is this - after I add the external mic I want to listen the sound from him in live time (with headphones or on speaker) and if it`s possible to record it when I want. Most important to me is to can listen the sound from the mic in live (directly in live time).
Can I anybody write or adapt some app to do this?
Best regards!
With StompBox (http://www.4pockets.com/product_info.php?p=81) you can do this, but you have a little delay....
which mic (and plug) do you use?
Hey, thanks... just tested the demo of the program, indeed have some delay, but this is not the problem - sound quality is very bad. The program "loosing" the quality from the mic. May be is from the demo version... I don`t know... but it`s too expensive to try with "full" app. So it`s not option. For example when I record with this mic and with the build in Voice Recorder I get perfect quality and long microphone range.
The microphone is volumetric, intended for security systems, work only with dedicate power supply. I use the 3.5mm input on the A300 (it`s input and output).
Any other suggestions for program or someone who can write something simple?

It's probably a condenser mic then, if it has its own power supply. Interesting idea, though, and I would like to see an app like this as well.

How do I make my secondary mic as Primary Mic

The main bottom mic on my phone is busted, which gives a static noise during calls but works fine when I switch to speaker mode during call which uses the secondary mic at the back.
I've seen many replace their mic for other phones, can anyone help with this??
Thanks in advance :good::fingers-crossed:

Broken main mic: how to use always the speakerphone mic ?

Below is the mixer_paths.xml file, how can I change it so that during calls the speakerphone mic is always chosen ?
Thanks
Have to use pastebin cause the code is too long and can't use attachments
pastebin . com / Panu8Bkc
I noticed something odd, in neither phone not telegram/WhatsApp calls the mic work, but if I record a call I can hear my voice in the recordings! And it's not a recordings with external sound noise so it's recorded with standard mic (I suspect rm4x has one mic only).
So the mic is working Ibet, it's just some stupid conf messed up. Don't want to reset though

primary microphone broken

I have a Moto X4 running Android 9.0 (pie). Recently, I have noticed that its microphone is not working in calls i.e. person on the receiving end can not hear my voice, only noise instead. And after searching for possible workarounds, I tried to put it on speakerphone but to no avail, noise still persists. But when I try to record a video via camera app, it records audio clearly without any noise whatsoever.
It has a primary mic and two noise cancellation mics. It seems to me that the primary mic has gone bad and the other two mics are being used in video recording.
So my question is, is there any way to use/force secondary microphone as a default mic through build.prop or some other alternative?
Headphone jack seems to be broken too, so I can unfortunately not use any earphones as external mic.
Please help.
I'm facing the same issue ,have you found any hack for that ?
