[Q] Bad Sound quality while recording video

Hi all,
currently running rooted Stock ROM 4.4.4. and while the video quality os OK I´m very dissatisfied with the sound quality when recording videos. Tried using the (new) google Camera app from playtore which is my standard app and also tried using the free OpenCamera app.
The sound is extremely muffled and it seems like noise reduction or internal audio processing is the culpit.
Is there any chance to get rid of the noise cancelling when recording videos?
I know it must be possible because for example the Hi-Q MP3 audio recording app I use allows me to choose the audio input (raw audio, main mic) and I get much better sound quality using the raw audio unprocessed sound input vs. main mic which seems to be amplified.
Any hints on this guys?
Thanks a bunch,
Kusie

Did you try and search? Few threads about this.

There's also quite a lengthy thread called something like "Microphone issues" that also covers this issue.

Very Bad audio quality in video recording

Hello guys First of all it's my first post in the nexus 5 group (i've did a pre-search) and i contact you with this problem
Last night i went out with friends at a pool party and used my nexus 5 for recording some videos from the stage. The music wasn't to loud, just like normal club music, in open space. Today when i took a look on the video i got scared...the sound quality is insanely BAD !. It's like the phone is set to +100 gain in the microphone... I tried normalizing audio in premier pro but with no chance. So i ask you guys, do you know any solution on how i can repair the problem. The best audio quality i had in recording videos in club (audio especially) was with my Nokia E51 that had the best mics i can find one a phone...
so here is a comparison:
In club music (closed space) shot with my Htc One S (no dual mic or things like that) -> https://www.facebook.com/photo.php?v=487777791348118&set=vb.100003477036350&type=3&theater
in club music (closed space) shot with my Nokia E51 (a 5-6 years phone that still records audio crispy clear for a phone ! - don't look at video quality) -> https://www.facebook.com/photo.php?v=247706518688581&set=vb.100003477036350&type=3&theater
last night with my nexus 5 ->https://www.dropbox.com/s/3vtisokit5ontwl/VID_20140727_032412.mp4
All the link are so you guys can see that exact problem that i have. I want to repair it, if it is possible in the stock rom (with a app) or if i need to install a custom rom, what is the best rom that resolves my problem and has best performance .
Thank you in advance !

I have exactly the same problem. Tried recording at a couple of indoor parties(so a little louder than your situation. Couldn't recognize any music when playing the video's afterwards. Terrible quality

Partial fix - i think
Ok so last night i got an app from play store called microphone that has a setting on the mic called mic gain. it was set to +32 dB....overgain ! so i set it to 0 and did some recording in the house with my audio system on a high volume and afterwards put the phone next to the speaker and seem that it records decent . but i think it is a problem related to software settings... will keep you updated on what i found

Sounds awesome. Thanks for your effords

Problem solved?
I can't post links so if anyone wanna fix this or just post the links from my post that would be great, thank you.
So I've found a solution, or at least a temporary one
Get the camera app called Lgcamera. In this app you can manually set your audio settings.
Set it to AAC and set the stereo option to On (this did it for me atleast).

I made a little video about it since I couldn't find this solution before, hope it helps!
/watch?v=RVWcE3dQoMk
Please help spread the video on forums where this issue is discussed so more people (and perhaps even Google?) can record without that awful noise reduction/cancellation! If enough people complain then they will probably (hopefully) implement these settings in the "Google Camera" app!

Thanks for the video! This is the video.

BE CAREFULL though with LGCamera, because I found that no matter what you choose in settings, fullHD (1024p) videos are ALWAYS recorded with 15 frames per second only (vs 30 as normal), making the videos look very choppy. So I deinstalled LGCamera again. Otherwise great app.
But I found a good substitute, it called Open Camera, link to the (free) app and also a possible video mic fix (reduces mic gain).

Hmm, strange. I do not have that problem. I record with 30FPS without any problems. Maybe something is wrong in the settings? Have you tried changing the video format around? The app is not that great but it does the job for now, atleast for me.
Edit:
I noticed that the front camera is not that great in Lgcamera, but the back I have no problems with. I recorded a video on my instagram if anyone wanna check it out. I'm still changing the bit values around hoping it will sound even better.
Speakers are "semi-loud" and i recommend watching the video in your phone or atleast lowering the bass if you're watching it with "real speakers".

Here are my settings for this particular video:
Back camera
1920x1080
H.264
Vid Bitrate 17mbit
Vid framerate 30
AAC
44100 Samplerate
128000 Bitrate (unsure of what value is best here)
Stereo OFF

Ok thanks, I might give it another try... Open Camera works well for me, though.
Did you check the actual framerate of your resulting video with a tool like mediainfo or VLC Player codec Info?
Nice guitar work btw

Open Camera works too, but I still get the audio artifacts when recording with a backing track. I get those in LG too, just not as much. Lg is in no way perfect, but the sample and bit rate allows a bit more customization if you ask me.
I'll upload one with OC when I get home! And thanks
By the way, what settings did you use in Open Camera? Or did you just lower the gain?

higher bitrate = better quality/higher filesize :good:

HUUUGE discovery today!
Update your LG-camera, go to settings and set audio to "voice communication" = headset. You can now record with your headset, see my instagram @Callemusicman for results!
It completely removes the noise cancellation!!

Isn't there any other solution? Because if i use, for example, Instagram, the sound is still very bad... so this LG app isn't usefull for recording with Instagram or other apps...

[Q] WhatsApp Audio Quality Record Solution

Hello,
With some devices, whatsapp audio record looks very awful, almost unlistenable. I know that the app provide some compression over the file to save bandwith, but the strange thing is that with other devices(Sony, Apple, etc...) the sound quality is just great. With this, i have 2 theories about it:
1- There must be a file with audio profiles that the app could use, just like media_profiles.xml that tells output, bitrate, etc, or...
2- Whatsapp is using a "generic" audio record method, not getting advantage of other audio options the device could offer.
The only problem with the second theory is that if you record a video throught the own app/3rd party, the audio is very clear and good.I've tried to look over system/, data/, etc/ and libs/ to see if there's any file that could lead to solution but nothing came.
Please, someone consider some further investigation about this issue, with i believe many people faces this.
Thank you.

[Q] LgCamera App bad quality video on Samsung S4

Hey everyone, I have a stock Samsung S4 that I like recording concert videos on.
I had a real big issue with the audio. I might have that fixed with BootlegMic. I have also installed LgCamera in hopes of finding a fixed focus for my video. I found that this app did let me use an external mic that my stock app did not, but I cannot seem to get a decent quality video from it at all
I have tried changing video resolution, video encoder, video bitrates, and file formats. Every conceivable combination that's possible, (I realize any video res past 1920 X 1080 is not supported), but cannot get any video quality even close to the stock video app.
Is there anyone with experience with this problem that can help me get it sorted out?
Thx. Jerry.

This may be late
This may be a late reply, but just in case any one else happens upon this thread, it might be worth looking at Open Camera app. Lots of tweakable settings, fixed focus, exposure lock, external mic, etc.
BTW, I just put together a bootlegMIC and it is fantastic.

WhatsApp can’t handle some U12+ videos

Hi,
I’m experiencing difficulties sending Videos using WhatsApp on the U12+, and I’d like to ask if anyone else has had the same issue? The problems have been...
1) WhatsApp throws up an error message, telling me that the video cannot be sent and that I should try another file.
2) Audio within some sent videos is corrupted (loud screeching/crackling noises).
If my mind serves be correctly, the problem seems to happen mostly with videos where I have zoomed in at some point. However, I because 95% of affected videos never sent in the first place - I can’t check back through my history to be sure that I’m right about that.
I found a German forum where somebody asked the same question, but no clear answer was found (although there was a suspicion that it had something to do with the audio recording mode). Additionally, the Play Store only has only one app review from a U12 user and he/she also refers to problems sending video.
Any thoughts?
Thanks,
Craig.

Got the same type of issue with Facebook Messenger, where the app was complaining about this "mp4 video format" not supported.
I recorded it with HTC camera app in 1080p 60fps.
No issue anymore if recorded in 1080p 30fps. Have a try...

I ran across something interesting yesterday when I was researching YouTube compatibility with the U12+'s videos.
What is your audio set to, 3D or High Res? High Res results in the video being saved as an .mkv, which isn't widely supported. 3D results in a fileformat that I'm unsure of, but it's apparently common enough to upload.

"Default" mode, so 3D.

Crap, sorry. I thought it was worth a shot.

Ni,
I had the same problem but unfortunately those times that happened to me I was not able to give an explanation ... I also assumed that it was a problem of use zoom but in the last wrong posting I had a video without apperenti problems of 42 seconds converted in 11MB he didn't want to go. So today I tried all the combinations of options that I found in the camera and the only one that gave me an error in sending was when I selected sonic zoom audio.
The real problem is that I think that in some way changing from the front camera to the normal one somehow changes the option, or during some updates.
So my advice is to check before registering if this mode is active.
For example in the last test I've recorded with the normal camera with high resolution audio then set to 3d audio. Now in the front camera I find high resolution audio but in the front I never touched options and I'm sure that before the beginning of my tests it was on 3D audio.
