[Q] Disable noise cancelling mic? - G2 Q&A, Help & Troubleshooting

is there a way to do this in the build prop or something? i'm experimenting with teh awful audio in the video camera and i want to see if it's the noise cancelling mic that's really screwing everything up.
i'm also looking to try to change the gain, anyone know how to do that?

I don't have an answer to your question, but have you considered the placement of your hand when recording? It seems to me that it would be easy to muffle the sound by accident.

My guess is if you open the phone app and hit the menu key and then call settings. from there scroll down to noise suppression and uncheck it.
Not sure there is a way to disable it in video though.

yeah, i read that android usually has different ways to use noise cancellation, like the nexus 4 has a diff classification for video and then voice.
also, I put my phone down on a tripod so it's not my hand placement. it's the bad mics in the phone.

Fix-ish
Jishnu made a mod that mods with the mixer path, i have tried it but the noise cancellation mic is still a little bit on. I'm using Xdabbebs camera mod so i hope he will fix this problem, heres the mod: http://forum.xda-developers.com/showthread.php?t=2706943
I've also seen people on youtube recording without the noise cancellation mic but he doesn't show how, https://www.youtube.com/watch?v=1NoxMTxiFvo
If you found a fix, please let me now:good:

did anybody find a solution for this, all my video recordings of my baby are horrible, literally unusable!! :grrr:

I take it it's still not been fixed then, ffs it's absolute ****, I'm sure the Mic software it's geared up for 3 mics and LG haven't realised the 802 only had 2

[Q] disabling noise cancelation during calls.

I'm looking for ways to disable the noise cancelation during calls.
People can't hear me unless I turn off the speakerphone mode, and speak directly to the mic. They complain that my volume becomes significantly low, and cutting.
I have used recording app to test my mic; my voice is recorded crystal clear.
I spent some time to search for the solution, I guess it is something to do with noise cancelation.
If there's anyone who knows how to disable the noise cancelation function during calls, it would be appreciative if you can share it.
Thanks in advance.

howto disable noise cancellation
you edit /system/build.prop from "media.a1026.enableA1026=1" to "media.a1026.enableA1026=0" it should disable the noice cancelling mic.
You will need a rooted phone and you will need to do 'adb remount' to mount the filesystem read write.
Dont forget to reboot phone after change.

I wouldn't even try to guess until you provide a reasonable amount of information about your situation. How do you expect us to narrow anything down without any clues?
Where is a sample video clip or even a decent description of the hiss? Tell us under what conditions this occurs, e.g. only on quiet environments, randomly, always, etc. Does it change when you change video quality settings, internal, external mike? What model phone, firmware version and anything else that appears even remotely relevant.
.
oki. ill upload a sample. it occurs under all circumstances, phone is pure stock so camera app and all is out of the box

That seems to be a musical selection.. so how to tell what is part of the unknown music track and what is hiss? Better would have been recording the quietest environment you could find. Or if the hiss only shows up when recording something, then play a recorded music track. And provide both the phone recording and the original music track so that it can be, more or less, subtracted or distinguished from the hiss.
It would help if the track didn't have interfering music or if you tried recording in quiet, moderate, loud environments, impulse sounds, etc with comments on whether the hiss varies under various conditions. At a guess it's the aggressive ALC (auto level control) when you record with the internal (?) mike. So when there is a quiet part in the music, the ALC cranks up the gain and the noise from the phone circuit becomes more apparent. On that theory it would be good to know if using an external mike alleviates the problem or not.
If it is an ALC problem.. there isn't much that you can do about it.. other than consider using an external mike.. not recording in quiet locations, which could be difficult.. or hope that someone disassembles and tames the ALC.

I have the same problem. Even returned my phone to the service and they did smth to the mic, maybe even replaced it. But my problem is still there. Search for check out 'hissing 001' video on youtube, i have uploaded a sampleml. they said they tried recording videos with two other samsung fives, and they all had hissing problems. But i just cant accept that a quality phone like thos has an amateur error like this... for others, sound recording sounds just fine. What can I do?
I'm having the same problem. Not sure when it started but now the hissing sound happens most of the time when I recorded videos. Recording voice through an app doesn't create any hissing sound. Anyone can provide anything we can try? TIA.

I just got my device back from service, and I have to say they did something to it, because now the mic works PERFECT, without hissing whatsoever.
IT could be sw related problem, but i strongly believe they gave me a brand new mic.
good luck!

Thanks for the update Darkerr9. I'm tempted to replace the mic by myself but not so confident I can handle it. Watched how to do it on youtube and will cost me around $25 for the parts. I still think it's software related issue since when recording just voice, it works perfectly. No white noise or anything. ... hmmm.. what to do..?

Ah, I see. Well I still had my warranty so they did it for free. And remember, the 1st time they (another service) tried to fix this, they failed to do so. I guess I got lucky now... voice recording quality is poorer, so that doesnt count imo btw if you use your headset mic, you will see (hear) that the problem is fixed..
Hi everyone. I have the same problem and it's very frustrating. I don't have a solution BUT I know the reason why it's hissing . It's not the microphone! When I record only audio with both microphones it's all OK. The problem occurs when front cam is on! When my girlfriend close up the phone to her ear she heard that awful sound (hissing). So the camera make that noise. Top mic is very close to the cam so mic gets that noise. Try to hear very closely to the cam and check if you have the same noise from cam.

[Q] Disable 2nd mic (noise cancellation)

Hi, when im trying to send some voice notes over Whatsapp it sounds terrible, I know that this is a common issue with the G2 so i'm trying to disable the 2nd mic to see what happen. I'm using Cloudy g3 2.0, but as far as I tried others it's not a Rom problem.
When I record using the built in record app everything is good, sounds clear, I tried using another apps that let me choose wich Mic to use (top mic or bottom mic) and it sounds good. I found in XDA some trick (here) editing the Build.prop but i think that thats only for Samsung.
It says that i have to edit from "media.a1026.enableA1026=1" to "media.a1026.enableA1026=0". but my lg g2 doesn't have that options.
Can someone help me out?
thanks!
Anyway to disable the second MIC for Whatsapp?

microphone issues during call on android N

From the past 2-3 days i started using the 6P for voice calling and i noticed the other side could not hear me properly so today i confirmed it my self and it was true my sound is muffled at best and i have to take the bottom speaker very near to my mouth to make the other party hear. There is absolutely no sound if i held my phone normally. Please help me.
I'd advice you to check the other microphone on the back. Clean it. And while on call, do not block it, or the sound gets muffled.

Blow it, preferably with canned air. Test your microphones by recording a video where you talk and listen to it. Does it sound normal?

Recording audio from third party recording apps works perfectly. Audio during video recording is also perfect. Its only during calls the issue occurs.

Does it still occur if you make sure that you're not blocking the microphone right under the rear camera on the back? Because that's the most common reason for that.

Yup. I almost never block the mic on the rear.
I have it too, already from android M, it has to do with noise canceling. I've tried allot of things. but none of them really worked. If I put the phone on speaker, the issue is gone, the person on the other side can then hear me perfectly again. Google should fix this problem. I don't think there's much we can do about it..
IS there a fix for this I have 2 6p's with the same issue. I am happy to root one and have a test if there is a known solution.

I can't explain how the problem was fixed, but here is what i did.
I'm not rooted BTW.
download build.prop editor

Tap add on the upper right corner, then input
Property name
persist.audio.fluence.voicecall
Property key
false
Then restart your device
Please try and let me know

I was able to do this on a rooted phone. Didn't have luck on the non rooted unit.

What this does is disables the noise cancelling mic during a normal call which is the source of the issue. There is an issue in the coding or the actual hardware where the noise cancelling mic picks up on your voice as background sound and tries to lower the volume of those khz which is what it is supposed to do with everything except your voice.... When you put it on speaker mode or record video it automatically turns the noise cancelling mic off which is why it works perfectly in those modes and why this little trick that I have been doing for over 2 years now works. It is just a simple build.prop change and all you need is root access and a text editor. The application is nice to make it easy but not necessary. I hope this illuminates the issue and why this little work around actually works. Trying to clean the noise cancelling mic or other measures will get you about nowhere as it is firmly a problem with the operation of the noise cancelling mic in normal call mode. I remember when we were diagnosing the issue on some thread here on XDA and some people said to put your finger over the noise cancelling mic or that they used a piece of tape to cover it which gave the same result, so we decided to just do away with it on the software level. I guess if you don't have root you can cover it with a piece of tape permanently or your finger while you speak on the phone.
Hope that helps; decided to post for posterity.
Also, I tried the program linked and it did not change the actual build.prop file for me, but rather made a new one which was not in the right place and therefore did nothing for the actual running of the phone. All you need to do is go into root -> system -> build.prop and find "persist.audio.fluence.voicecall=true" and change it to false then save. You can leave the other ones alone. I used Solid Explorer and edited the file with SE Text Editor which I gather comes with LineageOS as I only downloaded Solid Explorer and not SE Text Editor.

How can I disable the noise cancellation mic on CM13?

When I try to record the sound of a band or musical group my redmi 2 didn't record the sound right and in many parties I needed to throw the file away just because the audio is too bad of it and this is caused by the noise cancellation mic. There's a way to me disable it?
