Stereo audio for video recording: Backwards!

I don't know if any of you have noticed or not, but the Note records video in stereo! The only problem with this is that it seems the channels are backwards!
Left is right, and right is left!
This is the case when holding the Note such that the home button is on the right. Even when you rotate the device 180 degrees around, so the home button is on the left instead, even though the recording shows up oriented correctly, and the audio is correct as well, when you export to your PC, the video is now upside down!!
Has anyone else had this issue?
Is there a way to fix it?

Are we alone?
FINALLY!!! I've been searching for weeks for any information about this issue with zero success! I repeatedly missed this thread because I was using the terms "reverse stereo". Finally in a last ditch effort before posting a new thread of my own I decided to search for "stereo" only which led me to this thread.
I must say I was hoping I'd find some answers here but it does give me some measure of comfort to finally see that I am not alone. I was beginning to think that my unit was defective and it still very well may be. The only other explanation I can think of for such a sheer lack of information on this topic is that most people haven't noticed this issue, which is really difficult to imagine.
My issue is exactly the same thing: When I first noticed the stereo sound was reversed I thought that perhaps I was holding the device upside down in terms of the orientation intended for video recording, but when I attempted to fix the problem by changing the orientation of the device I noticed that the video was recorded upside down, meaning I was holding it correctly all along and the stereo is indeed backwards!
I've NEVER had this much difficulty finding information on such a major issue. So I would really like to know, as I'm sure the person who started this thread would like to know: Is this a widespread but relatively unknown problem or do a very select few of us have defective units? It would be really nice if ANYONE would comment on this! I'd be just as interested to know how many do NOT have this problem as those who do.

I wasn't aware that the Note records stereo audio on the camcorder!
Too bad it's reversed... :-(
But I hope there's a fix soon.

I wasn't aware myself until I watched video taken with the Note while wearing headphones. It was quite obvious to me that the device was using a stereo mic setup, but it was equally as obvious that the stereo was reversed. I wasn't able to find any settings on the phone to correct this. Incidentally you can see the microphone pinholes on both ends of the phone -- one on top to the left of the headphone jack and the other on bottom between the USB port and the S-pen well.
As for when it's fixed I still don't know how widespread this problem is, whether it affects all Notes or if it's isolated to a very small number of units. If the latter is the case then it's likely a hardware problem and will never get fixed. If you don't have any info on the solution to the problem you can still help by reporting on whether or not your device also exhibits this behavior so that we can get an idea of how widespread it is.

I know it affects my i9100 and my P6800...

I believe i read on the sgs2 forums that ICS introduced stereo recording for that device. Are you guys by any chance also running ics on your notes? If this is the case, it could explain why so few have had the chance to notice the issue.

There's stereo recording in gingerbread. I noticed it the same way Ajax did, I was listening to a concert recording I made through headphones and heard it. Though...I also learned the note sucks at recording in loud environments
Sent from my GT-N7000 using XDA

the note has always recorded video in stereo. noise cancelling mic for L, normal mic for R. except i've only just noticed that its reversed as well.

I'm on Chainfire ICS and just made a test video and noticed it was in fact reversed stereo!
Now here's what's very interesting:
If I flip the Note so the home button is on the left, my video image comes straight (not upside down) and audio properly aligned!
At first I thought that the grayed out option on the screenshot would have something to do with it, but I think that's for the front facing camera, and it flips the video horizontally not vertically.

Okay now we're getting somewhere! So it's not just a problem with the Note which is comforting...well, to Note users anyway. At the same time if this issue is as widespread as JEW is illustrating then the general lack of information or even discussion on the matter, not just on this forum but on others as well, is strange to say the least. I guess I should point out that the former was an attempt at a condensed reference to Jade Eyed Wolf; not trying to be antisemitic.

Actually I have yet to load any custom ROM. To be clear I am experiencing this reverse stereo issue with the stock 2.3.6 Gingerbread that shipped with the device. I don't know if stereo recording is built into the OS or if that functionality was added by the device manufacturer. I do know that HTC now has stereo video recording capability in some of their newer devices but haven't yet found any indication as to whether those devices also exhibit this reverse stereo behavior.

Yes I also came up with the brilliant idea of simply turning my phone upside down to record video. The phone appears to know which way should be up during playback, but have you tried viewing that same video on another device? Try viewing that same video on your computer and you'll notice that regardless of how it appears on your phone it is indeed upside down! What's more the sound is STILL backwards relative to the video!
As you pointed out, Rayan, the "save as flipped" option is greyed out because it's only for self-recording mode. It essentially allows you to save video as a mirror image.
This is good that we are finally getting some discussion on this issue. Perhaps we will now be able to get to the bottom of it.

I've only found out about this today. So I registered and saw the noob video.
The left and right channels aren't actually reversed. The camcorder is just left-handed; that means the primary mic (bottom next to USB) is fixed to the left channel and the secondary (top) is fixed to the right. It's kept this way regardless of how your landscape is oriented.
You'll just have to remember to record with the record button on the left. That's really annoying. I hope this gets fixed in ICS.

me too..
Hi,
any news?? I am experiencing the same problem..

Annoying if you are using a flip cover, the flap has to be kept held up.

Turning upside down helps on the device itself. Note can fix it on during playback.
But on PC it is upside down.
Ps. Yeah , my Note has the same problem.

On the PC, you can just flip the audio using whatever video program

Oh yeah. Terrible audio recording. Hissing sound everywhere.

Have the same problem with reversed stereo. That problem appears on OFW 4.0.4, CM9 and CM10.
I tired to demux audio track, revert channels, encode to aac and mux video with correct audio.
Why CyanogenMod Team doesn't fixing this problem for a long time?

Recently i sold my Note and as a temporary solution bought S2.
Guess what! It has the same problem.

Fix for how hard the sound sucks

Maybe someone has already posted this; it wouldn't surprise me. I was watching Dexter on my tab a few nights ago, and I said, "Wow, the sound really sucks. Let me turn it up." It was turned up. F***. Somehow, I got the idea to cup my hand around the speaker so that it reflects out to my ears... and it worked. So, I did some experimenting. 30 seconds later, I got it; I found out that if you hold any kind of card over the speaker, that because the speaker itself is on the slightest angle, the card doesn't block the sound, it projects it in another direction. Where the sound used to be low, bassy, and at times incoherent, the volume now gets a slight boost, a decrease in the bass, (and thus) the ability to understand what the hell people are saying.
Let me not talk anymore; I have a feeling people look something like this in reading my post:
So now, I'm going to post a picture of what I did to my tablet, and instead of trying to make sense out of what I'm saying, just try it for yourself. If you like it, agree with me. If you don't like it, don't agree with me! But for me, personally, this nifty little trick (which, by the way, does not get in the way of the folio I have for my tab, but may get in the way of yours) makes viewing a much more tolerable experience than it was before.

So, as you can see, I used electrical tape to secure an old card down to my tablet; it goes over the speaker, and very slightly past the edge of the device.
Again, don't try to understand my explanation, and don't knock it just yet; try it out. Hopefully, you guys get the same result as me, and hopefully, it renews your faith in viewing on your tablet.

The card trick is easy to understand, but it begs the questions:
-- Are you running a stock ROM
-- ICS or JB
-- Have you tried any of the generic Android volume boosters like Volume+?
I don't have any volume issues with my TF300T. I've got Power Amp (unlocked) installed as my music player and it uses Direct Volume Control 2.3+, though I'm unsure if this effects volume of videos from the web. Anyone? I'm also running seanzscreams Hydro 4.1 rom and I forget if he did any volume boosting--it would not be out of character for him to have done so.
What I want is the usb adio that Jelly Bean is supposed to support.

I am unlocked and rooted, running ICS, and I think that makes it a stock ROM, right? Sorry, I'm kind of a moron when it comes to stuff other than the simple. I probably couldn't even root this thing again if I tried.
And for your other question, I've never tried any volume boosting apps; it never even occurred to me to search for that kind of thing. If you didn't tell me about their existence, I would have written it off as being as ridiculous as searching for a vibration function on the Android Market I'll go try one out now. This isn't a messy option or anything but it's certainly not ideal. lol

Power Amp sound settings only control the sound of audio played directly from Power Amp.

Volume + definately works, i can vouch for that app

Xiaomi Mi A1 Volume issue with connected headphones - Volume self adjusts to DND mode

Recent Mi A1 owner here, as usual getting little joy from Mi support.
I purchased a new Mi A1 recently but when I connect the headphones the volume self adjust down to DND mode. If i try to increase it will resist and push itself back down. This is an intermittent problem but will usually happen within 2-10 seconds of plugging in.
The headphones are JCV with inbuilt mic and three rings. One button to answer call. When this button is pressed the volume reduces one step on the slider (volume slider display appears on phone.) They are working fine on my other devices.
The Mi A1 is Gold MDG2 running stock 7.1.2
I'm trying to determine if this is a hardware issue with the phone (in which case I can exchange) or
a software issue with Android
it has been suggested in (1) other thread that there may be an incompatibility issue with the inbuilt mic.
Has anyone else suffered similar issues? Any help or advice would be much appreciated.

I believe this is an android issue. I've experienced the same on other phones, but it happened so infrequently (1 or 2 times a month), it didn't bother me. The quick fix was to take the headphones out and insert them again right after it happens. I find it happens with IEMs (with volume controls or even one button for pause/play/fwd/back) that are damaged or well used/dying soon.
Since i read this thread, i went looking to see if there were some fixes. Can you see if you can enable your System UI tuner? Follow this path >Do Not Disturb>Volume Buttons Shortcut to off?
I only read this so i am trying myself as well and will see if i get this problem again. My reasoning as to why this may work is that i think the volume controls may be an issue on the IEMs/headphones. I think it must be sending some kind of command that enables the DND with the volume button controls. Anyways, just my hypothesis, maybe give it a try.

Thanks for the tip about system UI. I have disabled it and will be testing now to see the effect. The JVC headphone are fairly new but are budget. I will try to purchase the Xioami basic headphones this week to see if the problem persists. They have the same feature set as the current pair I am using.

Same here.
Sometimes the volume will increase itself, making bad things to my poor ears...
The stange thing is that sometimes instead of increasing the volume, it will stop the music or enable DND mode.

This isuse happen with some device not all. I think this is hardware issuse, not software. I asked one guy who use LG quadbeat 3 like me, he says everything fine with him.
Try to test with xiaomi test, the test auto recognize volume down button without press.
So what is solution?
Use headphone without mic, or just one "skip" button.
Really disapointed with this device. After facing warm color screen and laggy scolling, and jack problem make me feel tired.
The first and last phone with xiaomi.

Some additional findings:
It seems that blowing into the microphone causes the volume to reduce on the handset. Also, if i am driving the issue intensify's so it seems to be something being picked up by the microphone that is making the volume reduce.
Xiaomi customer support are baffled and only advise to take it to a service center.

Okay this might sound weird, but I faced the same issue in yu yureka.
The cause from what i was able to determine was this type of connector will work without the issue you faced,

In Yu Yureka the scenario was reversed.
My CX180's and my JBL headphones (don't remember the model) work fine with the connector with two "grooves" where as
another pair of JBL's (don't remember the model) and a model of Sony headphones with three "grooves" will give me the above mentioned issue. Again, Just what i experienced. Might not be the case for all.
(Tested on both the black variant and the white variant)

Almost assuredly, it will involve 3rd ring because the 3rd ring is what sends the commands and the command it sends is what I suspect is the issue.
2 rings means no remote/mic and no commands, those two rings are output only, only transmit the sound.

It don't think this a purely hardware issue. It's happened on my old phones (Axon 7) and specifically with nougat, never happened in Lollipop. Also, Nexus/Sony/Moto devices have the same reported issue. So to blame this fully on Xiaomi, I don't think is fair. If that many manufacturers have similar reports, it's clear its something beyond hardware or a particular phone/manufacturer.
The one IEM I had this issue with is one with a single button. So I don't think that is a solution.
Can't say I've had such a bad experience with this phone. In fact, I think it's made me interested in buying Xiaomi again, especially if they continue in the android one program.

Odd indeed. Have you tried with other headphones? I'm guessing the system ui thing didn't work then?
I tried with my Sennheiser Momentum (3 button cable), an old pair of KZ ED10 (single button), and a newer set of KZ ATR (single button), all without issues. The only one I have with this issue on are my other cheap and well-worn VJJB K4 (single button). I'll keep testing.

I can confirm the two pairs of headphones I have tried are "three ring" variety and both give issues. It seems to be something to do with the microphone picking up sounds as when I blow into the mic the volume will reduce one step and when I am driving it will reduce all the way to DND.
Surely this does not mean I cannot use inline headphones with a microphone? I guess investing in bluetooth is the way forward. This almost renders the headphone jack as useless. I will be purchasing the Xiaomi budget headphones (with inline mic and answer button) and will report my findings accordingly. These are also "three ring".

Follow up report for anyone experiencing similar issues.
Since purchasing the Xiaomi basic headphones I have not experienced any issues.
Possible cause: The Xiaomi have a higher ohm rating than my previous set, so it could be something to do with this. My old JVC HAFR37A had only 16 ohms whereas the Xiaomi basic operate at 32 ohms. Both headphones have the same feature set.
Thanks for all the replies.

Some additional information regarding the Xiaomi basic headphones.
Went for a swim today and after completing several lengths of the pool I discovered the headphones in my swimshort pockets. Expecting the worse I left them on the side to dry.
Later that evening tested the headphones and the sound quality and function were all intact!

Yes I have exactly the same issue! I thought it was my headphones that were not working, but in fact I see that many have this problem. I ordered new headphones.

Was able to flash successfully via Magisk and after a reboot, I can hear sound come out of the ear piece. It is very quiet and can't really hear it unless I cover the main speaker, but of course that little speaker is limited by its own hardware. Can it go any louder? Obviously only if its safe to do so!

Pretty weak actually. but still useful cuz you could still hear your music if you try to completely block the main speaker.

Hola
Many thanks for sharing this with us. Question: If we update our ROM every week or so, will we have to flash the mod again?

Depends. As magisk runs systemlessly, the module should just apply itself after an update, so long as you flash magisk again when updating the rom. However out of all my modules, there are a couple that don't stick (viper, vanced YouTube) and these need manually reinstalling/enabling.
So we'll see...

If the magisk module is installed, then when updating it will be applied by itself.

Hello, Nice job, is it yours? I have a project the past week that I try to achieve this, but it is not the same as Mi8 so if you have just changed the Mi8 version I think that it will not completely work.

Version with the same lines as you broke bluetooth connection on custom firmware, yes it's mine

Very good m8. It works here on 9.4.11. the earpiece sound is kind of quiet but pretty sure that is hardware limitation.

How To Guide Increase Soundquality of the Nothing Phone 1 Speakers tenfold. [Non-Root]

This tuning has been tweaked by my ear with year long experience as a listener to Hi-Fi gear.
My goal was to create a smooth natural sound-response, that minimizes fatigue.
It took me about 5 hours to measure the best result that should compensate most if not all volume levels.
It is supposed to only work with the Nothing Phone 1 to sound as intended.
Resonancy from the ear-piece is more likelier to appear but not concerning, as it is just air causing interference with the grill.

1. Download the App Wavelet from Playstore. Wavelet is free, without battery or privacy concerns and pretty smart.
It knows what device you currently use and switches profiles accordingly.
https://play.google.com/store/search?q=wavelet&c=apps
2. Enable legacy mode in Wavelet on the Symbol bottom left and apply all values that you can see in the Screenshot. (Channel balance can be turned off, if you prefer higher volume instead of better Stereo-seperation in Landscape.)

Will check the app out! Cheers

Thanks for sharing that it sounds wayyy better! Been using Wavelet for the last few weeks for headphones but didn't think to play around so much with custom stuff

Wow thank you! It really is like night and day.

Spectacular. Thank you!

What a difference that made. Massive music improvement. Thanks for sharing

This sounds so much better, thanks!

Yes, thanks a lot.

Difference is impressive yes, but it's weird with this settings i have some tracks (music) crackeling, hope it's just saturated frequencies, not push so much the loudspeakers.

Does this only affect sound through the speaker or will the settings affect my bluetooth audio as well?

the crackling you hear is air created by interferences with the grill that stops dust and dirt particles and only appears on the earpiece for me. i'm pretty sure that a damage is highly unlikely to appear by these distortions. the phone even on stock is borderline distorting at max volume.
from my experience this varies heavily on the genre you pick. i tend to have most crackling when listening to male singing or podcast voices but nothing when listening to drum n bass or dubstep tracks for example. i rarely listen at max volume though. it works with all stock ringtones too.
i designed this EQ curve to work with all volume levels but most importantly to be focused around 40% to 70%, because this is the volumerange i mainly listen to when watching youtube or gaming.

I listen this track on Deezer
Thanks for your thread and reply

Simply brilliant, makes the phone's audio quality up to a great level either to speaker or headphone. Nicely done mates!

Will this work if set once and forgotten, even if the app isn't running in the background?

impressive. This sounds so much better. Nothing has to read this thread and make this equalizer changes part of the firmware, this is such a big improvement

Definitely an improvement!

Brilliant. Thank you!
