One picture is worth a thousand words
Recorded with Tapemachine. Same conditions, same audio source, same settings... The only difference is hardware autogain control enabled on first sample, and disabled on the second one
How to disable it during video recording? No idea yet
that's a good improvement,maybe supercurio knows how to do it.that would be awesome for a good video recordings.
At least we now know the problem. Very good work.
Hmm i am really waithing for this fix. recording is HD is quite cool and good quality but its useless because the sound always go's bad because its recorded to loud.
New info:
AudioHardwareInterface: AudioHardwareBase::setParamenters(downgain=0)
That's how Tapemachine switch off hardware auto-gain
And auto-gain off seems only to work with mic set to front (AudioSource: VOICE_RECOGNITION)
Thanks to aLogcat app

hohoho. Now we just need someone with the knowledge to do that. Thanks rafalense for find out this
Don't forget that it needs those settings to be optimised for audio calls. Most likely, with theses settings, while in call, the audio will catch more of the surrounding than the vocal itself.`
So the best way for this to works would be to make an apps that does the command then goes dormant. Then you can record whatever and, when done, disable and close the dormant app (kinda like TrackerBooster)
BTW, don't forget that you're recording with a crappy built in microphone from a smartphone. I'll try to do the same with an external microphone to see.
I own both the Galaxy S and the Samsung Wave s8500.... And, i gotta say, that the Wave has MUCH better sound when recording video at 720p + Its much better synced with the actual video... Maybe you could look at the Wave and how i manages sound? It has the Bada OS (unfortunately)
Hi !
That's something I'll fix soon using hardware auto-gain.
For now I'm working on a jitter issue and the gain is the next one in the TODO list
As the jitter one is quite difficult I cannot give ETA yet

Thanks a lot, supercurio, without you, our galaxy wouldn't be as good as it is.
any updates on this item yet? this would make recording video's so much better.
Try this kernel, mic gain issue seems to be solved, plus other sound improvements:

Also, follow Supercurio. Headphone & FM Radio improvements already done, currently busy with mic:

I'm busy moddifying stock camera, in order to increase samplerate and bitrate. Updates to come
Great efforts by the members of xda, REALLY.
The idiots at Sam**** should have sorted this out though.

video bitrate is already quite high but higher audio bitrate might be a good improvement
Hardware is able to record @48000 and around 256Kbps, but video and audio are out-of-sync
My guess, something coded wrong in the driver, so lets see if voodoo sound new kernel fixes it, and then we will record hd video with hd audio as well
A did a test for you minutes ago, check audio info:

why do you think this fixes it.. from my readings that kernel does not muck with video recording rates or microphone gain...
Hardcores K12L?
Check yourself. I did, and mic distortion is reduced considerably

I would recommend trying 44100Hz.

Also possible:
16000 - 22050 - 24000 - 32000 - 44100 - 48000 tested
How can you get the camera app to record at 44.1KHz?
Edit: Got it. Weird though, even though it's 44.1KHz, the cutoff frequency is 12.0KHz instead of 22.050KHz. Not much improvement over 8KHz cutoff, but better than nothing.

Does the new FW improve the quality of sound when recording video?
As I posted long time ago and never get any solution - the sound of the video is always strangely deformed,
WHILE when recording a sound note - it's fine!!!
Is it dependend on any setting OR the fact of storing video on memory card directly?
I actually never had this problem. What ROM are you using? I don't think it's caused by storing it on the storage card.. I mean, how the hell would that alter sound quality?
Try messing about with the settings a bit and also check what apps you installed, perhaps some codec got messed up a bit?
Haven't tested it, but, I would imagine that the bitrate used when recording video (128 kbps ?) is far inferior to the bitrate used while just recording audio only (>1000 kbps ?). Bitrate alone makes a big difference in sound quality.
Hmm
I havn't used it on older ROMs but hae taken quite a few vids of a robot I have been building over hte last few days and it has been fine, although the sound was mostly of myself and my team laughing and shouting, even the very loud sounds didn't clip or anything.

Thanks for reply.
Hello!
It seems like the microphone AGC does not work with MR2.
The recording is distorted if you try to record loud sound, and the recording gain seems to be set at a fixed level and not adjusted to weak sounds.
Yes, I have tried to activate AGC (Start-Settings-System-Microphone AGC). Seems like this setting has no effect at all.
I am sure that this worked prior to MR2, because I have some old recordings on the memory card that are nicely adjusted and with much better audio quality than now.
Could there be some registry settings?
Any suggestions would be appreciated.
Hi have the same problem... after update to MR2, the microphone don't work.
I am really interested to use Skype, after MR2 Skype works fine on my mobile...
Bump!
Anyone?

Confirmed. Video recording gives normal sound,
when recording in Notes for instance is distorted.
Yes. And it's very irritating because the recordings had very high quality with the first firmware version. And it't much better with camera recording. So it's not hardware.
Today I realized that the phone don't have any bass response at all when you record a video. You can put the phone right behind the speaker and it won't record any bass... but if you use the voice recording app, it does recognice bass.
Like this video i've found in the internet:
There are any way to deactivate the stereo recording on videos?

Old news, there's a whole topic on this already with like 200 post.
Supercurio is aware of the problem and is already working on a solution to be released with his VooDoo sound and color.
delete it, i've found a lot of threads like this .- Sry
I have my Verizon S5 currently sitting on 4.4.4 NK7. I've noticed no matter what video recording app I use, whether it be Snapchat or the native camera app, that audio on video playback always seems a bit distorted if the video was captured in a loud environment. Yet I see friends with other newer android phones and iPhones that have recorded footage the same venues (concerts) where their audio is much more tolerable. Has anyone else experienced this? I've been holding off on updating to lollipop, but if that is a known fix I might go that route.
For example, even recording a video on my car with the audio at a normal volume results in distorted audio quality.
Lollipop won't change anything, cause that's a big problem to not fix immediately. Are you possibly covering a mic when recording? Are phone calls clear? I'm not sure how to fix your problem, I'm just throwing out ideas. A search didn't bring up anything.
Apparently it's a common problem within the Samsung phones:

Was hoping there was a software option to adjust the gain level it records at.

I saw the xda thread but wasn't sure if it was the same. Someone said disable the noise reduction option, and that should fix it.
I have the opportunity to really put the video and audio recording abilities of this phone to the test tonight at a couple of music venues. I've got to admit that the audio settings of the manual video camera and the HD audio recorder confuse me a bit. I understand that this phone has a raised level at which it'll clip (130db) but I don't even really know how to go about making sure I'm not clipping audio. (Video, sure, but not audio.) Any advice, instruction and/or input is appreciated with audio stuff. I want to give this thing a fair shake.
Second question... I know where two of the three mics are, one top and one bottom, but I've not yet seen anyone point out where the third one is, ideas?

If I'm not mistaken the 3rd Microphone is internal, I recall seeing this on one of many youtube reviews I watched..
A weird place to keep a mic.
Ok, didn't get any input so I went in flying blind last night. For audio settings, I went into the HD audio recorder and looked at its concert settings and used those. I think I still need to figure out the settings better but I can actually hear more separation to the parts of the band than I could when I was there. (It was loud and just about a wall of noise!) So I have two links attached below. One was recorded just with the main lens. The other one I switched between the two. As you will see, there's a couple of things to point out, all which were obvious and to be expected. 1) My hands are shaky, especially standing there holding a phone up at various points of the set and through entire songs. 2) The wide angle lens obviously doesn't do as well being f2.4 at 8mp vs f1.8 and 16mp for the main but it did allow me to take in the whole band despite standing up front. 3) I'm not sure if the stabilization was active or not. I think it might have been and there's just only so much one should expect from it. Any way, the settings I used for the visual portion were FHD, bit rate high (24), ISO 3200 at 1/60 with video set to 30fps. (Oh! And I need to add a note, the refocusing is my fault for touching the screen during recording.)
