Poor, low quality audio during video recordings - T-Mobile Samsung Galaxy S7 Questions & Answers

When recording videos, audio volume is low, and the quality seems way off, almost like there's a slight robotic effect, or as though the audio track's bitrate is lower than it should be.
To add to the oddness, there will often be a tenth-of-a-second (give or take) at the beginning OR end of the video that's at normal volume and quality...
As far as I can tell, nothing's covering any of the mics. I'm currently running the latest Nougat beta, but the same thing happened on 6.0.1. Maybe a clean install is necessary? I don't even have a lot installed.
Here's a [bad] video sample, originally recorded with Skype as a video message but later saved:

You can hear the bad audio at the beginning. It also lacks additional bass. Quality gets a little better through the rest, but you can hear the brief portion at the end where volume is where it should be.

When I record videos, I get very low sound playback. Is this normal?

Whenever I record videos with my Fuze, I can barely hear anything when I playback, even with full volume. I have to stick my ear into the back speaker to hear. Is this normal, or is the mic clogged up or something. I know its not the speaker because music playback is incredibly loud with the speakers.

[Q] How to improve sound quality during video recording

Is there a way to improve the sound quality during video recording on the Sensation?
When recording loud music in a club or a consert, the quality is realy bad.
I guess the microphone input level is to high.
Is there a working solution for this?

Goto HKCU/Software/Samsung/Camera
Find AudioNormalCodec
the options are:
0 - Default : GSM-AMR-NB 8000Hz 1ch (this is the default but has lots of high pitched noises in the background)
1 - MPEG4 AAC 16000Hz 1ch (this so far is the cleanest audio that I found you can get during video recording)
2 - Qualcomm QCELP 1000Hz 2ch (this is the MMS setting, not good at all for video recording)
I have found this solution, but i can't find "AudioNormalCodec" in my Omnia II...
if you can, pls let me know.

You know that you posted this in HTC Sensation forum? Can you tell me where can I find register on android device?
Hi.
Got the same problem, I tried to make a video during a gig and the sound was horrible, no way to fix that you think ?
Thx.
got the same problem sound qualityis okay but after playin in pc or phone i got some noises during playback zzz zzz sound
Just came back from a concert yesterday and am really dissapointed about the quality of the sound. picture is just amazing but my girlfriends Galaxy S had way better sound recording. anny progress in this?
I'd read in other thread that unchecking the stereo option in video camera settings the sound was better...

not so sure about that to be honest, recorded at a gig last night with latest revolution hd 4.1.4 rom and the sound was horrible
really would appreciate it if someone knows or could find a way to take the recording volume down a notch or two

Surely there must be an app or developer out there who knows how to fix this mess. Again, another event recording ruined. The htc sensation is fine for unamplified natural voices, but even speech or music at LOW volume is pingy, distorted and generally sux.
The Chic Corea concert I recorded was a total disaster. unticking stereo still not effective. Why does iphone make great recordings, but htc can't get it together? or is this an android issue in general? Don't get me wrong... love android and open source, but really... someone needs to nail this one. Is there any point in complaining to htc? ♥

Natural voices are ok, but this makes two concert video recordings ruined using my htc sensation. the sound is distorted pingy and beyond painful to listen to. Can't some brilliant developer create an app or fix for this? Is there any point complaining to htc, or are they too busy getting out their latest phone?
Sux that iphone video recordings. Natural voice and music is ok, but anything amplified, even at a moderate level, is ping-distortion city. and turning off stereo setting doesn't help much either. Thanks for the whine, now the cheese.
done some digging and i think, from what i read, android wasn't given a facility to lower recording volume. so i guess that plus a highly sensitive mic equals crappy sound recording with no fix, for the time being hopefully
I don't think it has to do with Android. I remember at some point on my Vibrant I was able to change the setting and got much better sound after. It may have been a DSP manager app I did it through or it could have been a setting when I was using CM7. Either way, I'm almost positive there is a way to adjust it.
sound quality
I have found a big improvement in sound quality by UN checking stereo sound in the video recorder setting menu.
+1 on this, I'd love to figure this out
I agree. This is one of the weakest points of the sensation. We have great video capture - but the sound can totally ruin the experience. If a Dev could figure this out it would be golden!
I am not sure about this, just a quick thought. But MAYBE the noise comes from the mics on the back of the sensation? Maybe HTC didn't thought about turning off the those mic's while recording.
Just a thought...
I believe the stereo recording uses the 2nd mic above the camera, while mono just uses the standard mic, that we make calls with. I did some tests just by covering the mic holes while recording.
I just think it would be great if we could have a DEV take a look at how to lower the mic gain.
There is a thread over in the HD2 forums, that deals with edits to some lib files for mic gain, but I don't know if that would be something to take a look at. Here is the thread:
http://forum.xda-developers.com/showthread.php?t=1162224
We need this fixed!
I think the problem is that there is no normal codec for audio coding. Oddly Andoid revolution HD writes with a frequency of 44,100 Hz, but the quality is very poor, although an order of magnitude better than in HyperSensation. Unfortunaly, developer chamber is at the bottom, and understandably so - because enough other bugs.
Just wanted to check in on this old thread and see if this is all still in issue with the Sensation and the latest ICS Roms? Wondering if HTC has fixed the high mic gain by now?
Thanks

Low volume with anything other than Google Music

Volume was very low through my earphones (I've tried multiple), so I looked around the forum for similar threads. There's a LOT of threads with low volume issues. I found Voodoo Control, installed it, and configured it to output maximum levels. Google Music is at an acceptable level now where I won't put it to maximum volume, but Moboplayer sounds like I have it at ~50% when I actually have everything maxed out. It's pretty much useless to watch a movie where there is any other noise even with my in-ear phones that isolate sound.
I'm running the original Prime 1.5, not the revised kernel (no SoD issues here). So I'm getting a bit desperate here because of all the other little issues I've had to deal with this tablet... What can I do to resolve this?
I can't be the only one with this issue. Google Music's volume is more than sufficiently loud after installing Voodoo Control and maxing out everything. I originally thought my problem was limited to Moboplayer, but it's anything else besides Google Music. I've viewed my videos through Mobo, Rock, and the built-in MyNet app. I have normalized the audio stream to 100% for my videos, but even when set to "max" volume, it is nowhere near loud enough if there's any other noise in the environment.
I really want to like this tablet (and I do to some extent), but there's all these little issues with the software and some hardware that are really making me -__-
I can't say I have this issue but I can say that the sound quality sucks and even at the highest volume it is too low.
I installed Power AMP which has an equalizer with a Loud Speaker Out Pre setting which is louder than anything I have seen yet. It seems when you set your tab to this any other music player will pick it up and it is definitely louder.
Give it a try.

Sound on video recording

Hi there,
I noticed that when I'm recording a video in a noisy place, like a concert hall or something like that, the sound is horrible, you can hardly understand what is going on. Is there a way to solve the problem?
Unlikely. Sound recording is a delicate thing. To produce quality recording, huge directed microphones are used, the sound is recorded at a very high rate, and filters are applied. None of those can be done on a phone.

OK, I understand that, I'm working with sound. But I read somewhere that this is happening due to the ARM codec, which compress the sound at a very low biterate. Can this be changed? Or, at least, lowered the recording volume?
Again, no, because - 1) you're limited by the codec HW implementation, 2) the write speed to SD card is limited, and the less you compress the audio - the more bandwidth it takes.
The recording volume can be lowered, I think. Just not sure how - never tried.

Question Sound dies down when the bass drops.

When playing songs at full volume with outdoor mode on at full volumes the vocals die down when the bass hits, it sounds like a cheap Bluetooth speaker. Anyone else facing the same issue?
Please try it and let me know if the vocals get dim when the base hits.
Try the Song Glass House by MGK or any of the drake songs.
Thank you
Your sure it's not a sound system issue?
If the device performs well with quality headphones it's likely not the cause.
You should be coming out in the 24bit digital realm if possible otherwise it will degrade the sound quality if the source is high fidelity.
Hi.
So I noticed this issue early on and I tried the song you mentioned and have replicated the problem.
Except, I don't think it's a bug. In outdoor mode, the volume is boosted but at that volume the bass would be distorting in these speakers and therefore it lowers the overall sound.
You can replicate this even without outdoor mode on but with bass slider at max in audiowizard. You will get the same problem.
So, it works this way because that's how it's designed. Unfortunately.

Alright thank you, but that's the thing I mean the speakers are good but you cannot use them to their full potential, the front camera is absolutely terrible for video calls, Snapchat is just a blurred face, I mean what's the point of this phone when it cannot get the basics right it overheats but 40C is acceptable. But thank you for confirming, I thought there is some hardware issue with my phone.
I think that's just the audio processing trying to compensate for the bass and prevent speaker over-excursion with soft clipping or dynamic range compression. The speakers are inherently limited in size and as far as I know, the phone doesn't use the entire back or front to improve bass response (like LG's Boombox feature).
You can try to EQ the bass down or disable the DTS processing.

Use Poweramp for complete equalizer control.
It's limiter works flawlessly.
If the phone 24 bit digital output and you use it there should be no issues on the phone side.
