Can someone check voice record quality - Xperia Z2 Q&A, Help & Troubleshooting

I decided to try Sony's answering machine feature. I recorded a greeting. When I played it back it sounded like I was talking through a towel or something. I called my girlfriend and she said I sounded fine, so I don't think it's a mic issue.
As a check I downloaded 2 different voice recorder apps and both record with the same muffled sound.
Could you guys try and let me know. I'm on the most recent firmware 17.1.A.2.55.

Some new info to report.....
I'm hoping a dev reads this and can shed some light.
People have been complaining in certain situations that they can't hear me on their end. Usually in noisy environments (on my side)
I downloaded "Easy Voice Recorder" in an effort to run some more testing. This particular voice recorder lets you override the phone's default for
1) noise suppression
2) echo cancellation
Turning off noise suppression makes a huge difference. Still sounds like **** compared to every other phone I've had in the last 5 years but it's improved greatly.
Thinking back, the times when people complained about the call quality on my end, I'm pretty sure my Z2 noise suppression is to blame.
Two things then:
Someone please download "Easy Voice Recorder" and test how a recording sounds. Then disable noise suppression in settings and test again.
Secondly, does any dev know of a way to alter the default noise suppression functionality?
Again, as I have divulged in several threads, I am unlocked, rooted and have lost my DRM keys. If this is not an issue for anyone else I'm wondering if it could have something to do with that...someone please take a minute and test this for me..Thanks.

Hi I got similar issues. Look at my thread, "Bad call Quality".

[Q] Voice echo?

Hi,
I've been having complaints on the other end of people hearing their own voice echo during calls. It seems to stop if I put it on speaker or lower the in call volume.
Any thoughts/solutions?
I'm currently running rooted stock on T-mobile.
My wife said she heard herself when I called her over the aux in my car. Didn't have that issue with my mt4g. The volume in the car was the same as always, maybe the phone volume needs to be changed.
Ill report back when I play around.

I just flashed stock w/ Odin and left it unrooted - the problem seems to have stopped for the moment. I'm hoping it's related to network service and not hardware/software issues associated with rooting.
They're just messin' wit' you...cause they're jealous!
problem came back - only was able to stop it by turning off noise reduction on the in call menu.
it seems that it was actually caused by me inadvertently activating the noise reduction feature. after deactivating it, it stays off by default and I no longer have the echo issue.

Thanls ill give this a shot. It'd be nice if it auto-disabled when in car mode.

I don't know if it was this yet but my caller volume got pretty low after I did this, can't confirm yet. And yes call volume was all the way

noisy audio recording

Rooted stock I9300XXLFB (international) version. The audio recording is very noisy. I tried several applications for video+audio recording and audio only recording but the noise is always there (EDIT: except of call recording where the noise is ok but overall recording quality is low, of course). Here are two examples taken with the stock Camera application (with the audio track taken out of the resulting mp4 using ffmpeg). I was hoping that the latest fix from radeonxt might help but it is perhaps even worse (more noise from the lower frequencies seem to appear) - the first one (before.aac) is before the fix, the other file is after applying the fix. Both of these were recorded at night in a completely quite room.
before.aac
after.aac
Is this a general S3 problem or is it something specific for my S3? Any sugggestion how to fix it?
I tried 2 other things.
Noise removal in audacity worked pretty well. Of course, this was a very simple spoken word example and it would probably not work well with eg quite background music but still it shows that the problem might simply be no noise reduction while recording audio.
Then I recorded a fake call (using Call Recorder) - and the noise is not present there. Of course, it is a much lower quality (8000Hz at 6.4 kbit vs 48000 Hz at 45/80 kbit) but still it shows that a software fix might be possible. However, strangely enough (at least for me), the noise is not even present if I turn off call noise reduction in the call advanced options:
mediafire.com/?5liar18ekjt5afm
(sorry for not providing a full link but it seems that suddenly I am not allowed to include links??? I get an error message that new users cannot post links - strangely, I was allowed to do that 10 hours ago)
Anyway, the only conclusion I can make is that is seems likely to me that a software fix is possible.
However, first I am wondering, can somebody confirm having the same levels of noise in audio/video recording? If the problem is in my device then I'd rather return it - I certainly want to use the S3 for recording videos from time to time and it is close to unusable for me at these noise levels...
Any input highly appreciated!

same problem as the S1. wait and hope that voodoo sound for s3 will be out soon...

If I knew this is a general S3 issue then I could just wait and hope voodoo for s3 is out soon indeed
However, so far I have not found anybody either confirming or denying the noise on his s3 (I do not personally know anybody else with S3), so I am wondering whether it is not a problem specific for my device...
If anybody with S3 could make some audio recording (eg using the Camera application) under similar conditions (just a few words in a quite environment) and compare the noise level or post the recording here, that would be a huge help... but any report (I think/I don't think I have the same problem) or comment would definitely help me too...
I have just found a few S3 video recordings on youtube that are significantly less noisy than mine, eg http://www.youtube.com/watch?v=sfsdxx7dK8k (even though he is complaining about audio, it is still much less noisy than what I get)
So I guess either there are different versions of S3 with different microphones/drivers or my microphones/drivers are not working properly. Anybody has an idea how could I find out what is the case?
Anybody? Any idea, suggestion, comment?

How to turn off Noise Suppression?

Hi,
I have an intermittant issue where people can't here me. If I turn speaker phone on they can. I want to turn off noise suppression, but don't see any settings for it anywhere. Pressing the menu hard key while in call does not reviel anything. Is there a reg edit or something I can try?
Thanks
The LTE has two mics, one with noise suppression and one without. There is one at the top and one at the bottom which provides stereo when recording video etc.. When speaking, try either mic and see what the results are. Its possible one mic is defective or needs to be cleaned etc., the only info I could find was for the GS3 but maybe this will give you some ideas. I think some ROMS have that setting but I have never looked or needed to disable.. Good luck.

Thanks! I am pretty sure I have a dirty mic, but looks like I have to take the phone apart or kill the noise suppression to fix the intermittant issue. Just trying to avoid the dredded flash to stock/trip to sprint store. Thread you posted shows some promise, but was hoping for an easier fix

Sound echos during call

I have a really bad sound echo during call at the receiver side. No matter what I use: messenger or hangout. Is there any way to fix this somehow?
I have stock 6.01 android rom.
There is no problem with my Nexus 5 with the same android version.
Do you have a case on it? If you do, take the case off and try again.

I tried, but the problem still persist. I tried on the same network, the receiver hears himself/herself during the call and my voice quality is poor and low volume.
I had the same problem once on a different device, but that problem solved somehow. Maybe it's just a setting problem.
I think I found a fix for this. I found out this is happening if the speaker volume is quite high, if I reduce it the echo stops and there is no complaint about my voice quality.
Any advice what can cause this? Noise cancellation?

Boomsound is your answer. I noticed this when I use hangouts. When I plug my earphones in, the receiver can't hear the echo anymore. When the speakers are loud, even the microphone can hear the output.

Noise reduction in video and call (SD)

Hello,
i have problem probably with noise reduction - when i record video in quite room, audio is ok,
but when background a little bit noise, i hear only some scratches, sometimes a quiet voice ...
The same situation is when i record call, barely hear voices... is there any possibility to change settings in noise reduction?
I'm using aosp, on miui there where only problem with call recording...
Is qualcomm have something similar to mtk engineering menu? Maybe some settings in build.prop?
I think it's a problem of the secondary mic (it is located next to the headphones port) which is used for noise cancellation. I haven't experienced an issue with video recording yet (because I haven't recorded any video) but I have problems with call quality. Every time I place the phone a little far from my mouth I hear complaints that the other person cannot hear me, which wasn't an issue with my older phone.
The temporary solution I have found is covering the secondary mic with my finger (thus disabling it). Also from what I've found in the internet there are some other phones with the same problem and there are ways to disable the secondary mic through software but I haven't tested it yet. Here are the links I'm talking about

I repeat that I haven't tested this fixes myself and I don't know if they are compatible with our phone.
Thanks for answer,
when i was looking for a solution, i saw tread from one+ but i was counting that is fix directly for our model.
Firstly i change build.prop - and now testing, in audio platform i dont have such line, solution from nexus same situation - dont have those lines.
Hello..
I have problem with background noise during audio call.. because of that noise.... I didn't talk with person who is in call..
