Is there any way to disable the default and overly-aggressive noise cancellation that occurs when recording video? It's just awful and way too aggressive. Perhaps something in build.prop or other config files? I'm rooted and regularly flash roms, etc. so I'm willing to try anything

I have recently switched from S3 to Note 2 and I have experienced a significant change in gtalk sound. Now it's significantly darker, and my partner and I miss the slight bright noise in our audio conversations. She's had no changes on her phone and besides, before selling my S3 we had the chance to test both devices at once and clearly the sound was worse in note 2.
I had tried several things regarding microphone gain: N.E.A.K. kernel with wolfson audio control, alsa mixer, default_gain.conf tweaking, with not very noticeable changes.
I figure out the problem is not mic gain but noise cancellation. There's an option in stock phone app to switch it on or off during a call. Also some apps for sound recording have that option (Asr from play store).
Is there any way to disable noise cancellation under gtalk? Maybe in a configuration file? Does anybody know where that file is? Or maybe there's a way to disable noise cancellation globally?
Thanks for your help!
Have you tried disabling noise cancellation from your phone settings? Not sure if it will affect gtalk, but it's worth a shot.

So I get why noise cancellation can be useful during calls, but noise cancellation in video recording is absolutely ridiculous!
Also I find while recording audio from an audio recording app that even there was no noise cancellation selected for the app, my OnePlus 3 was still working it!
Please...Please! I don't want this! It is spoiling my experience of a perfect phone.
Yawn... go to the audio mods thread... there is a fix for that... please read around in the forums first before opening a new thread, thanks.
Hello,
I have nexus 5X 32GB. Since I bought it I have a following issue with audio recording.
When I record a video using google camera app, audio is clear and loud. But when I use ANY app that records just audio the audio is not that clear, not that loud and it's like that something is applying a filler on it. It seems to me that it's trying to remove noise. Audio is not constantly loud and clear. It's like on a sea... up and down. You can here the difference from 2 audio files I attached to this thread. One is recorded with audio voice (sony https://play.google.com/store/apps/details?id=com.sonymobile.androidapp.audiorecorder) one is recorded with google camera app (MP4 is just converted to mp3).
When I was recording it the music was not loud at all and the conditions of recording were the same (distance, angle, loudness etc.)
On Android 6 factory reset didn't help.
After upgrading to Android 7 the problem still occurs.
I tried a lot audio recorders and all of them had the same bad quality sound
Any idea what to do? Do you have similar experience.
Seems to me like the mic sensitivity is too low on the audio recording. If I remember correctly, you can increase it on custom kernels like ElementalX and probably also with mods like ViPER4Android.

Thank you for your tip.
Well.... that's weird. I bought Nexus so I don't have to deal with software issues like this and now I am supposed to modify the stock rom? Isn't there any other solution?
Am I the only one having this problem?
Change build.prop?
I have the exact same problem and I would love to know how to fix it! First guess was a problem with noice cancellation. That is why I took a look at build.prop, where I found the following entries (among others):
#
# ADDITIONAL_BUILD_PROPERTIES
#
...
persist.audio.fluence.voicecall=true
persist.audio.fluence.voicecomm=true
persist.audio.fluence.voicerec=false
persist.audio.fluence.speaker=true
...
In a thread regarding problems with voice quality during phone calls, they suggested to change some values to true/false, as these entries seem to be related to noise cancellation. But as far as I can see, noise cancellation ist switched off for voice recording ("persist.audio.fluence.voicerec=false"). Or should it be "true"?
I am confused... Any other suggestions on how to fix this??
Well I am still awaiting any solution. But there is none. I expected a fix with Android 7.0 and later with 7.1 but there is no change...

compared with other cell phones
I had a chance to test other nexus 5x and this device didn't have this problem so this must be a hardware od software error which occures only in some devices.
There's noticable noise suppression in video recordings which really affect the audio quality. As much as I like it on phone calls, I don't always record voices when shooting video. The noise suppression really destroys the sound of the environment. Anyone know a way to disable it?

Only way which I think is shooting in manual mode and disable wind filter, and optionally use HiFi audio recording which will enable recording sound track in lpcm.
But I very much doubt that tiny mics of G7 are capable to correctly picking ambient audio of 10-20 dB volume levels. They're too tiny, you should rely on external USB microphone with much higher sensitivity
It's nice to filter all but human voice sometimes, but, there are times when I want to record music, ambient sound, etc. and the filter just crushes to silence all sound below some dB level. That means all fine details in recordings that are not that loud are just lost in the final recording due to the aggressive filtering.
It appears to be enabled system-wide: Video recording, Voice Recording (Even with the built-in LG audio recorder app), Whatsapp voice notes, etc.
The only way I have achieved to bypass it was with the "RecForge II Pro" app, with the next settings:
Audio Record: 44kHz. Stereo(Native) 128kbps
Source: Front Microphone.
Disable AGC: Not marked. (If marked: the recording is in REAL stereo, but filtered as mentioned above, so is just like the recordings from the LG app).
Even with this, the recording is just "Duplicating" the bottom mic signal to both channels (R, L). I cannot manage to get real stereo without that filtering.
It bothers me sometimes when recording videos os stereo audio recordings, because it has a pretty good camera and good quality built-in mics, but it gets compromised with that audio filtering issue. Let me know if you know about some solution for this problem.
Thanks for your time.
Use HD voice recorder app by LG. Or use manual video from camera settings, enable Hi-fi audio and click on Hi-fi when you shoot video.
