Audio distortion/clipping in loud environments - General Questions and Answers

Hey Guys!
I have a problem lately on my Galaxy S6.
When i record videos in loud environments the audio gets really distorted and the video gets unusable.
Its really annoying since i like to record videos when i go to concerts etc.
Never had a problem with it until a few weeks ago.
Does it have something to do with nougat?
Here are some examples:

Do you know what causes this and is there any fix?
Maybe theres an audio mod which includes auto gain control or a limiter or something?
Thanks in advance!

[BUG] Crackling sound on calls and music, can anyone help?

Hello,
I am a proud owner of a couple Android Phones since the HTC G1, the HTC Magic and so goes on.
Now I was very excited to get the Nexus S, but on the first day of use, after making all the updates to 2.3.2 and installing all my usual apps, I noticed a crackling sound when hearing music from the speakers.
I can not find the reason of this but would like to know if someone had a problem similar to mine, and if yes, if it was possible to solve it.
There are some facts about this crackling noise that I point as follow:
- The crackling sound is not present all the times. The phone works well when playing shorts sounds like ringtones and notifications. I can hear everything crystal clear;
- When I start to hear a song (tried many different players, all the same problem), or when I am playing a game that uses constant music or sound effects, the crackling sound starts after some minutes of perfect sound (usually between 01:00 and 01:30 of good playing);
- It seems like a irregular white noise, like playing a corrupted MP3 file, that gets in the middle of the media;
- It beguns with a low volume compared to the media and gets louder as time passes, until it gets more frequent and as louder as the music playing;
- At first I thought of a broken speaker, and checked the headphones, but the crackling sound appears when listening music on both headphones and external speakers;
- Then I noticed the crackling sound appears on long voice calls too.
Well... I thought it could be something related to the software, so tried the OEM recovery process (Settings > Privacy > Factory data reset), but it was not sucessfull.

I noticed the same thing while listening to Pandora. Not sure what's going on. I'm on Modaco and don't know if its something in there or not.
I hear the noise after about 30 minutes of pandora.
I'm having the same issue running Modaco while listening to music via Spotify.
Just got back to the stock ROM, I'll see if it's any better and keep you guys posted.
I can now confirm that stock ROM is not affected by this issue.

[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.

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

Best Voodoo configuration to record concerts?

Hey, I just installed Ardat v1.7b2 kernel and the Voodoo control app and I'm wondering what's the best configuration to record a concert, I suppose that i should chose the loud environment recording preset, but should I activate another option?
I make this question because I just have recorded different videos in my bedroom with loud music and different recording presets and I couldn't notice any change. So maybe I did something wrong or I'm not configuring it correctly, because I'm a complete noob.
Thanks in advance!

I don't understand any of the stuff either
I just switched everything on and told myself that it sounds better.
I'd like to know the best settings for listening to music in general as well and maybe if someone could somehow post a video about sound quality before and after applying the patch, that would be great.

This is something like the before and after.
Before (a concert I recorded some months ago):
After (in my bedroom with loud music and the microphone just in front of the speaker):
The situation isn't the same, I hope I can go soon to a concert and record some videos.

Audio Playback Issues

Hi guys! So, i have a problem with my Galaxy S6, specifically audio. Sometimes, when playing music or watching video while audio is playing through the speaker, the sound will get "choppy". That's the only way I can describe it. It's like the volume is constantly going up and down, and there's a bit of crackling as well. It seems to get triggered by a screenshot, a screen rotation, when changing the video quality, or when the phone gets hot when playing a graphics-heavy game. I know a factory reset would most definitely fix this, but I'm trying to find a workaround, since a factory reset is a really heavy process, because i have a lot of stuff on my phone. If someone experienced this issue, or knows a fix, please help!
