[Q] Video playback buzz audio

Hi all, yesterday I installed the Romulus rom and i begin to testing some things, when testing the camcorder I changed the media.stagefright.record parameter to false to record a video and it worked, but when I reproduced the video I hear a buzz in the audio as if the mic was too sensitive, i tried another videos that I record with another roms and I get the same result the buzz in the audio, then i tried some videos that I download from internet (game trailers, movies, etc..) and i dont hear the buzz in the audio, at last my last test was to tried the recorder video in the pc and again i hear the buzz. The thing is when i played another video in the pc that i record with other rom i hear the buzz too, so my question is Has anybody has notice this with any rom ???? Did other roms use some noise reduction to played the videos that the Romulus doesn't have???
Thank's for the help.
cheers

I just made a couple test videos while on Romulus, and I don't have a buzz.. Everything should be mostly stock on Romulus, so sound/video quality should be no worse than out of the box..
Also, what do you mean by reproduce the video? - just play it? Did you have anything plugged into your phone while you were recording (i.e. usb, headphones) that may cause interference?
One thing you can try is check the "Audio Scenes" settings in the camcorder...

When i'm saying reproduce the video i mean play the video (sorry for the confusion) , I didn't have anything plugged to my phone, but maybe your right i didn't check the audio scenes in the camcorder perhaps the solution is there, thank's for the tip i miss that .
By the way nice job with the romulus, i really like it and the mod lockscreen it's great.
Thank's again.

Microphone pretty quiet in calls, random noise in videos?

I tested out the microphone in calls and I have to say it is pretty quiet and dull sounding.
Also in videos, everytime the mic turns on you hear a random noise besides the actual sound that is recorded.
Can anyone confirm that?

Yup. I can't speak for the phone call part of it, but I am having the same issue everyone on this page is having, regarding video recording sound...

Distortion audio in video capture

Hi guys (sorry for my bad english)..
You have a problem whit MT7-L09 fw 137SP03 the distortion audio in a video captur in a ambient with high volume? (Concert or music hall)..
I have this problem.. video whit audio very very bad..

I have the same problem with mt7-tl10...... only when high volume sound is recorded
I think the solution is to search for an alternative recording app.

Hi @alexre123! I've purchesed Rec Forge II pro, but in recording have same problem... audio distortion..

only in high volume, right?
in normal volume mine records fine, but in high volume a lot of distortion.

for loud volume it is normal. There is a mode in the audio recorer about with the "concert" preset try that.. if it distort there also.. if not maybe you can get imrpovement thru a 3rd party app..
But bass frequency is usually what cause the audio in these type of microphones..
I would like to add though that I am very very impressed with the audio in video recording compared to other smartphones. But Loud volume I do not know.. I have never been on a concert with the phone but I know it cant handle high volumes here at home..

Hello and thanks ..
The volume in recording (both video and audio) is always high and distorted. I have not found a way to lower it. Do you know how?
I tried to record bringing the volume out down, but nothing changes.
Much use to record my band in the rehearsal room, but so I can not. Thanks!

Maybe You can try to use an external micro

In what format do you experience the distortion? Are you filming in full HD mode ( 1080p) ? I experienced audio distortion when filming in full HD. I have some old films at a football match that I did in May and I have no distortion and the sound was verryyyy loud. That it's intersting. But I was filming in HD mode ( 720 p) not full HD.
Do you have audio distortion when filming in 720p also or you didn't tested? And then I had also different FW. Now I have B125, and then I had B120. I didn't tested yet with b125 to see if I record in 720p the distortion will appear, so I don't know if it't from the firmware or from the video format.
Test it in 720p to see if you have audio distortion and let me know.
Ps: I have mt7-tl10

Hi!! Filmed in 1080 and 720 but still have a distortion..
I've recorded only audio (no video) with an external app (rec forge 2 pro) but have still problem..
I think that we have a decrease a microfone amplification..
I've a MT7-L09 fw B137SP03.
(Sorry for my bad english..)

With previous firmware ( before b137) you had the same problems? I'm thinking could be from the firmware also, who knows...
Your english it's fine, don't worry. It's not my first language also.

Great!
To buy a Mate 7 with this fw.. b137...

Awful audio distortion/clipping in loud environments.

Hey Guys!
I have a problem lately on my 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:
youtu.be/wb_8UHzyEO4
youtu.be/Dh4ZNHt-hsc
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!

Hi, I am having the exact same issue,
One day in a club my microphone was fine and the next absolutely unusable with horrible clipping!
Did you find a fix?
Calum

Same problem!

wow..what a grap phone i got...they are not able to put in a working limiter / loudness adjustment..

S8+ 4k Video Camera Lag / Stuttering

I noticed that 4k video has alot of Stuttering. I am recording directly to the phones memory, and it happens if recording handheld or even on a stabilizer. Is anyone else having similar issues or know a fix?
Here is a sample video recording:

If you go to camera settings and turn off stabilization it will be fine. Ois will still work this just turns off eis.
Eis uses a lot of cpu power and thus the stuttering. Known issue. Hopefully there will be a fix

Thanks, didn't think a feature would make it not work well. I think it would be better if they disabled it by default since it causes issues in 4k. But this will work for now.

Same issue
I have the same issue but it lags then speeds up, I looked for a shutter setting in my camera, but there isn't one. Has there been a fix for this yet?

This has happened on any Android phone that I have used since the Note 4. I have the phone set to record to the SD card (A fast SD card capable of 100mb/s). Image stabilization and auto focus are turned off. I begin recording and everything is starts out smooth for a few seconds. Then a slight pause. The footage then speeds up to compensate. At first I thought this was merely a playback issue. I exported the video to my PC and the same lag is apparent. I hate to say this, but I have never had this issue on iPhones.
