[Q] Background noise, the microphone defect? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello at all,
I searched in the forum but not appear to be others with my issue in the forum
When I try to record a video or a sound I obtain noise in the background.
This is a example: https://dl.dropboxusercontent.com/u/21152890/Voce 001.m4a
This problem that I got was the same with older firmware and the same after a wipe
In the video is the same, what should be ?
Thanks

problem is only mine?
1 suggestion, if you want people to help you, upload media to a more user friendly(read: where you can just click and listen/view) method.
Yes I had some noise on mine too. I actually noticed that there was more noise after I did a factory reset; I have no idea why??? I viewed old movies without noise, and the ones had noise... But if you look at youtube, all the videos have the noise, so I don't think it is really that kind of a problem. Software could help this with filters...
problem is that noise is sometimes more than voice volume..if you download videos, you can notice that volume is too much low...if I speak, volume is too much low...
I don't understand why? because voice recorder application has not this problem!
Problem is only mine, because a made a test with a my friend and his volume recording is good..

Note 3 speaker distortion after flashing CW12

Hey, this is my first post on this website and here it goes.
I recently flashed CW12, the latest version on my Note 3 (htlecan). After flashing the ROM, I noticed my speakers were distorted and making weird noises during any audio playback. I never had this issue in touch wiz
I wanted to ask you guys if this is a issue caused by CW12, I understand it's not the official version, but could it also be an internal issue?
Cheers!
You mean CM12 ?
Sound crackling. It's a known issue since forever.
Disabling system sounds may help.

Microphone issue ( Maybe Noise Cancelling)

Hello guys, i'm facing a very annoying issue, since i updated zenfone 5 to lollipop, my microphone randomly and at most time, the microphone doesn't work, during a call the other side can't hear me, but if i put in speaker mode, the microphone works well, also in recorded videos or audio, there's no sound, curiously, if i speak near the upper mic hole, the other side can hear me with a low quality voice. In nexus 5 there's a similar problem, and if you change the "persist.audio.fluence.voicecall=" to true in build.prop the problem is solved, so I guess the issue is in microphone noise cancelling. I want to know if there's a way to solve this, where I can disable the noise cancelling, i searched in build.prop but i didn't find a option related to mic/noise canceling.
P.S. I already change the firmware from stock lollipop to shell rom 5.0 and did a full wipe and the problem persist.

HI,
maybe you fixed you problem yet (I'm sure you did after more than a year, but for other people having that problem).
Open claculator and type .12345+=
Go to BoardMic_Test
Make loud background noise for eg. from PC select one under youtube for phrase "industrial sounds 10 hrs"
Tap Start and talk to you phone.
Stop noise and listen results.
You may repeat procedure several times as results will satisfy you.
Try the same without noise, should be OK.
It works for me, no mic replacement, no software upgrade, no restarts, no restore factory defaults
