[Q] audio distortion when video recording - Galaxy S I9000 Q&A, Help & Troubleshooting

i was at a concert.....was recording one of the songs.....however on playback, it had an awful audio quality....too much of distortion like the speakers blew up or something......my friend had an iphone 4 and another had the n8.....for them audio was perfect.......i only encountered this problem at concerts......my other normal videos are fine
i am very pissed at this!!!
is this a hardware problem or software????

Yes, it's a known issue and it doesn't look like Samsung is going to do anything about it... You can try going to a service department and go for a repair but if it's the mic itself another one isn't going to fix it.
It seems that some other apps (can't remember the name now) are able to record more properly so hoping for a software fix in the future (and more in the way of CyanogenMod then a fix by samsung).

Bump - remains a problem. I have all latest froyo/updates, Galaxy S.
Have recorded video alongside a friend with iPhone. His phone = great audio, mine = solid hash of distortion, unrecognizable original sound.
Has ANYTHING been done about this????
Call quality is ok - definitely not the same problem.
To be clear - I am not looking for an audio-only recording solution, but one that fixes the quality of audio in video recording.

Hi,
i found something by installing voodoo sound kernel and the voodoo control app.
You can change microphone recording settings to "Loud enviroment -with DRC"

[Q] ADC audio capture recording level and aliasing

Hi there
last week I got a new Samsung Galaxy S GT I-9000, and although I am generally happy with it, I am very disappointed with the ADC recording quality.
As others, I noticed it after asking a friend to film me playing at a gig, and the audio was completely unuseable.
After digging around and some experiments I found so far 2 serious issues:
1 - As others pointed out, the microphone input level seems to be unadjustable. I have digged around in the hidden menus, where I could find a way to adjust the input level for speech calls but not for audio recording.
(Audio -> Handset ->I2S1 Rx Gain, although I am not sure if the signal clips before or after that point when doing audio recording ).
2 - This is an issue I have not seen documented anywhere: no matter what application I use, I am not able to record at any higher sampling rate than 22.050kHz. This is with both handset and headset microphone. But what is probably worse, is that the signal is not (or not very well) low pass filtered (antialised) before being downsampled!! I tried recording a frequency sweep from 0 to 16kHz, and the first 8kHz (11025 Hz inn 22050 Hz sampling rate mode) were Ok, the next 8kHz (11025Hz) where aliased like hell. Try record a 10 khz and a 12 kHz tone at 11khz adc rate and you will get a 10khz back in both cases, almost at the same amplitude ! Not sure why I can't acces 48kHz, as I read somewhere that the audio chipset should support that.
Anyone know if there is a fix for either?
Just uploaded the recorded sample for reference.
This was a 100Hz to 16kHz frequency sweep of 30 seconds.
The test setting was far from ideal (just played it out on my PC) but it gives an indication. Note that aliasing is so bad that even harmonic distortion gets aliased, and it becomes really loud when all harmonics get imaged back to the same frequency by the aliasing process. If the situation is not fixed, there is no hope for high quality audio for the galaxy... Anyone knows if with 2.2 upgrade this will work?
Do HTC desire or wildfire have similar issues? I am seriously considering swapping before my 14 days trial runs out: no point in having HD video (main selling point of the phone) if the audio is close to unuseable (and I don't want to go to Apple just yet)
The voice quality on my Galaxy S is really bad. I've had several people say to me that on calls it's difficult to understand what I'm saying and that the sound is either muffled or distorted.
I tried some recordings with the voice recorder app and these two don't sound clear at all.
Could this be caused by the same thing you're mentioning, or do I have a problem with my phone?
How do other people find the call quality (that is, someone listening to you calling *from* your Galaxy.)?

I think this is related to the same bugs mentioned as the subject of this thread.
BTW, it looks like HTC desire has the same issue wrt video recording, so it might be an Android issue rather than a Samsung one...
You can find some additional details in the modaco forum, on thread samsung-galaxy-s-i9000-mic-sensitivity-recording.

After flashing the european firmware JM1 from Kies I am able to record at 44.1 kHz now!
Haven't checked aliasing yet.
I'm on JM2 and this is a topic that I would very much be interested in.

Same problem gggrrr
I recorded a friend of mine singing last night and the audio on the video is terrible and i mean really terrible, the picture is fine but the audio, nope.
I have heard that there is a way to load in a new kernal to be able to change the sensitivity of the mic but i'm not sure if that is the way to go or not, i just want to be able to record video that sounds good, please help.
Flash a kernel with voodoo sound. Then the audio quality will be amazing

I've used voodoo sound ever since I go this phone. You don't even have to flash a kernel anymore, supercurio's made it even easier, as long as you have root just go onto the market and buy Voodoo Control Plus and unlock the true audio capabilities of your Galaxy S
I started out with JPY and using Tape Machine I've been able to record just fine at 44100Hz. Same with JVB.
Thanks for that, i installed voodoo control plus, really easy to do, at a gig tonight so i will record and see what the sound is like on the video, thanks again

Camera app doesn't record audio - no sound!

I'm having an issue with my Nexus One, it doesn't seem to record audio when recording video through the Camera app, all I can hear is a little mechanical noise. The weird thing is, the camera records audio fine when I install another camera app such as UCam Ultra Camera... meaning it must be a software problem right? However, this problem started last week on my N1 with stock ROM (never rooted), and since I started having the problem I thought I would root and flash with CM7.2 but that didn't solve anything.
I hear the phone has 2 mics, one by the charging port and one on the back by the camera. The one on the back by the camera works fine when I use speaker phone or play music, and the one by the charging port works fine because I can make and hear calls. So the microphones seem to be fine to me, but the camera won't record audio!
Anyone have any ideas? Could UCam be using a different mic than the camera app leaving it still a hardware problem? I'm open to DIY, I would like to replace the mic on the back actually because I feel thats the problem, but I can't find one and don't know how to replace it, if anyone has any resources it would be appreciated.
I've searched around, there are many people with this problem, but no answers. Here are three threads that attempted to find solutions, I hope this will be more successful.

I have this problem too, but I have a Samsung Galaxy S3. I flashed a few roms, and somewhere along the line, my camera app has no audio and all I hear is some constant white noise in the background. Exactly as you describe. Other apps' audio and mics work fine. I can't find a solution.
Same issue here with the edition of the mic not working when in speaker phone mode.
I was rooted 4.1.2 tried unrooting relocking and flashing stock but no joy. I think this is a hardware issue

[Q] Rode SmartLav mic compatibility and AGC of audio level

I have been given use of a Galaxy Cama EK-GC100 and asked to record someone talking to camera.
I am looking for a mic solution and found that a TRRS headset mic works. This led me to discover the Rode SmartLav.
Their site discusses iPhone compatibility and a bunch of devices but the Galaxy Camera is not on the list
I suspect it'll work but confirmation from anyone with experience would be great!
Second question...
Is there a way to set a manual audio record level?
I am getting nasty noise between sentences in quiet environments.
Thanks, Steve
It works
I tried a Rode SmartLav mic and it works correctly with the Galaxy Camera
I am still looking for a camera app that will give manual record level control

Noisy video (camera)

I have a problem with my Samsung Galaxy S5 (G900A) where my video recordings are noisy.
Even in the quietest of conditions I hear this hissing sound in the background in my videos that I record using my phone camera.
I've searched the web and found out that I'm not the only one, but I can't seem to find any solution to it.
I've cleared the cache partition, the phone isn't wet...
Any suggestions? Such an expensive phone with such a big problem...
I want to try this hack to enable stereo sound on the phone but I am not sure if it's for the ATT version and if it'll work with the current ROM (stock, rooted Android 5.0.0 rom)... is there a similar thing available for my phone here? Or am I safe to try this hack?
Well, that hack works... I now have stereo sound (or something resembling it... now plays music through both speakers) but that didn't help with the camera thing...
I was kind of thinking that the hack had to do with microphones and not speakers... had to read more into it.... but the hack is still nice lol
I've read online of people fixing the issue by using a pin to clear the holes in the case where the microphone is... well I tried that (using the dull edge of a needle) and now the recording is much louder but the noise still exists (this hissing).

Recording Video - No sound

I've just been testing the stereo speakers in a quiet environment, by speaking from either side of the phone, however on playback I can initially hear white noise and slight rustling and then the audio just cuts out completely at the point that I spoke in the recording.
I'm a bit perplexed as to what is causing the issue. Has anyone else encountered this problem?
I have encountered the same issue. The phone completely stops recording sounds in video mode
Had the same issue.
Changed codec to h.264 in camera settings in Video Size section and all of problems had gone.
But the phone still cuts sound after ~3 sec while recording in applications like snapchat or messenger.
Edit: After restarting the phone both applications record sound
So this problems still occurs, despite being on the latest update.
Anyone else encountered this? Just wondering whether it's worse doing a full reset
I have the same issue. Do you have other sound apparatus BT associated? It seems to be linked with BT associated sound with my car. It comes back after turning off and on the phone.
Still quite annoying..
Reboot your phone.
Turn off all Bluetooth devices and Bluetooth on phone.
Try another camera app.
Turn off accessibility features.
Clear data for the camera app.
Verify the mic is working on other apps.
Verify permissions for the camera app.
Are you on a stock firmware or did you perform a different kind of upgrade?
What ROM / firmware.
Thanks for all those tips.
Emui 9 as I had the phone. I bought the P20Pro used two weeks ago and upgraded Ota to 203. I did not tried the camera before the upgrade so don't know the issue was already there.
I have found same issue with P30 Pro.
I'm normal camera mode I had the shutter set to mute.
When then going to video mode this setting carries over and sets mute too.
Still testing if other apps and services can override this setting when

If you wish to silence shutter on camera but not use the native camera setting to do so, use tasker to mute the phone when camera app is launched.
This mutes the shutter sound but does not stop video audio from recording.
Hi guys, Huawei P30, ELE-L29, EMUI 9.1.0.153 (C431E4R2P2)
All videos recorded using the phone have sound when played back on the phone (with 80% volume setting) but it can be hardly heard after taking such a video file to YouTube or any other smartphone/computer. Mic gain problem?
I have the P20 Pro and although all setting on video are set to mute it still records sound and it's really annoying as I cant turn the dam thing off, someone techy please help, I'm going back to apple when my contract is up don't like this at all, camera is amazing and only reason I moved back to an android tbh, thanks x

Mute won't mute the video audio, I think it's for UI sounds whilst in the camera app, don't think you can disable audio whilst recording..
Why do you want to? Just curious.
Just to add, I ran into the same issue on my fully update P30 pro.
I was out on vacation and recorded 3 videos back to back. 4K30, HEVC. When I tried the play them back, I found no audio was recorded. The video does have an audio track, but when I pull it out and look at it, it has nothing. Very annoying when you record something that you'll prob never see again in your lifetime (unless you return someday) and find out it didnt work right.
If I test right, everything's working fine. This is the first time this has happened.
