[Q] Sound noises when recording video - Nexus One Q&A, Help & Troubleshooting

This is my first time asking a question on xda-developers so if this question has been answered in another forum, i'm sorry i didn't realize it.
This has been an issue for me since last year but i didn't mind at the time but now that this is 2013, I've had it.
Every time I record video using the Nexus One, there's this hissing noise like "BZZ,BZZ,BZZ..." in rapid succession and instead of sound coming from my surroundings, the hissing noise is there and I can't do anything about it. I did tests such as blowing my breath to the mic or tapping the phone and yet there's this noise that isn't what i recorded. Surprisingly, the mic works in almost EVERY application EXCEPT the camera app.
The Nexus One is rooted with Cyanogen7 running 7.2.0 and I think the problem is with the camera app.
I even tried going back to stock to see if that would work but it hasn't!
I was wondering if this has been confirmed with other phones or if there's a solution for this kind of problem.

[Q] galaxy s mic problem

hi:
besides the galaxy s I have a nokia 72e and I want to ask if anyone has a problem with microphone (with Galaxy s)? maybe is not something serious but when i`m talking from the e72 the people hear me more clearly than i talk from Galaxy s;they complain that my voice is muffed.
i don`t know what to do .... if i go to warranty and stand in lines and let the phone for almost a week in their custody,and find out after that the phone was alright...?!
i discovered the difference by chance,when I called the same person from both phones shortly.
if anyone knows this kind of problem please let me know......
First of all, this doesn't belong in development.
Secondly, yes there is a known issue with the mic on the SGS, or rather the mic drivers and settings. I don't think there is a community fix for this, and Samsung has not acknowledged it publicly, so I don't think it will be fixed any time soon.
jap, I just finished my mic mod there. I looked the youtube video
how to disassemble the phone and bettered the mic part.
The mic is situated 90 degree and little rubber channel is used
to direct the sound to mic. This tiny rubber channel was incorrectly
pressed in so half of the input was covered. So a I widened the channel input
and also drilled the hole in case little bigger (do not do that! it may ruin the
case chrome). Sounds little bit better.
Now, is this normal, to make a mod to better mic sound for a elite phone ?
yes, there absolutely a known issue. I purchased two of these phones, and both had the exact same thing you describe. It was absolutely horrible!! I received two replacements, and the sound quality is MUCH MUCH better... BUT, it is still no where near where i think it should be. all my previous HTC devices had far superior sound quality than the Samsung GS. The Galaxy picks up voices 100 feet away... and noises from other crap that none of my other phones ever did... I'm hoping that it is in fact a software thing, and once 2.2 is released, it has better canceling technology built in. Will see..
Construction of built-in microphone is not a problem... The problem lies in software. If you connect external mic (fe. headset) sound is still disorted. There's no way 2 microphones will be broken. This is the same headset which is shipped with Samsung Wave and that phone has no problems with build in and headsets microphone.

Good point !
But in my case there was 50% better quality with headset ..
Now that I have some of yours attention - why don't I see more post
of video jerkiness, stuttering problems ?
In my phone After every 1 sec. the video recording stutters slightly.
I saw this we saw this all ready in first galaxy test video.
My main problem with the mic is the distortion... It's so bad you can't even record a clip in the car with the radio on. It already gets distorted, something to be ashamed of samsung.
Nice to have HD recording, too bad the only thing worthwhile is the picture since the audio is utter crap.
(Yes, a bit frustrated )
Is it still this bad with the JPK Froyo firmware?
Moved thread to Q&A section
Never noticed this before. I hope this is software related. More and more bugs keep on appearing, almost wishing I picked another phone. The Galaxy S has downright amazing hardware, yet Samsung choose to let it down with all the bugs

I've just bought the Galaxy S for my other half and have noticed exactly the same problem . Went back to the shop and tried the test phone they have in the shop. I only noticed a very marginal improvement (guy in the shop didn't notice any difference).
Anyway I would be interested to know if anyone has swapped the phone since noticing this problem and had an improvement - i.e. is it just a dodgy batch of microphones from Samsung?
Thanks all!
Is there still no fix for the microphon problem? 5 million items sold and each owner of it cannot take a proper video from a concert or on a fair or even on a birthday party, where there are louder surroundings. Annoying.
Please, devolopers, have an eye, ups, ear on that!
I've been complaining about this since July... no response

Most smartphone will get crappy sound when using built in microphone on High volume environements. Basically, it's hardware limitation with the built in microphone.
I've done some test (see in the accesorie sections for result with video) and you can use an external microphone with an adapter for theses type of recording.
So, the delivered headset does nothing better than the onboard mic.
It is definitely a matter of the hardware?
Asap I'll give an external mic a try....(using the Nokia-made TV-cable...)

Pls reply to other forum messages showing that u also have the same problem after replacing the phone (it only solve part of your problem), because I see your msg from another post that u were saying that u have no problem after replacing the phone. And that is not totally correct, u still encounter some problems
My problem is slightly different
Hi,
I got a sgs early 2011 and I quickly noticed that the voice recorder gives a very bad sound when listening back. I started to be afraid I would be as bad when calling someone. The problem I have is a horribly distorted sound with a terrible noise in the background. The recorded sound is simply useless.
later I was very happy when I did the call test as the use of the embedded microphone to call is alright. I even rang a friend beside asking what he thought about the sound qualify and he said it was ok. Then we swapped phones and I too thought the sound was fine.
But we tested again a recorded sound & video with my friend and it was awful.
After finding this thread I decided to try again and to compare with the head set microphone. For me it makes a huge difference ! The noise disappears and the distortion too.
first I thought the problem came from the compression rather than the microphone and now I don't know what to think...
My phone is on Froyo 2.2.1 (thanks to this website).

I have the same issue.
Check the comments, there is a guy who says how to fix it, but he is not very precise, so i asked for more info.
We'll see
Πάνος
Try out Speedmod by Hardcore in the dev section. Includes fixes for the mic and headphone output.
No need for Audio boost or any hacks. Sound is the way it should be now
A lot less background noise on mic now and no more EU regulations degrading the audio quality anymore.

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

Nexus 5 MICROPHONE - Audio Recorded On Videos

In a video in 1080p on the outside, the video will look and hear perfectly. The problem comes when a video is recorded inside a house for example. If you record a video in total silence, when playing the video if you put the volume up will listen very weak one "shhh" If you record a video with a TV background with the TV volume on the sound sounded choppy. Or if ye are silent recording, you begin to talk, you will notice a change to play between silence and sound.
I leave some videos from youtube where you will notice the problem (play with the volume as high as possible to notice more the problem):
http://www.youtube.com/watch?v=SQm6Yeo0DxE - This video perfectly burn notice the change on the outside and when passing record indoors
http://www.youtube.com/watch?v=EB4_awhWd9A - The television cut sound.
http://www.youtube.com/watch?v=TyciEt7dsSs - Here notice the cuts perfectly with the TV sound in the background.

Same here, my nexus is a new one , 5 days old.
Fix with 4.4.2¿?
I've got the same problem.
Updated to 4.4.2 right now, but can't test as it's night atm.

This happens to me as well. Not just when recording, but most annoyingly when talking to people on the phone. They complain that my sound is cutting out like the videos shown above, even though I hear them perfectly.
I am on stock 4.4.2 and my n5 does have the issue with audio in video rec. I am on fauxClock b15.

same problems but thanks,.
I have exactly the same problem. I had it on 4.4.0 and I still have it on 4.4.2.
The hissing on silence in audio/video recordings is really annoying.
I hope this can be fixed...

Same problem here :crying: it has to be a software problem, can't be a hardware issue in all devices. I love the phone! but for me this is a deal breaker :crying:
Was trying to test this for myself but mine won't save videos at all. Bizarre, probably a consequence of messing with the camera software.

[Q] Strange call problem

Hey there!
I am very happy with my HTC One even after the announcement of the M8, but since a few days I have a very strange problem.
Every time I try to take a call, I need to enable the speaker, since the one I am calling with can't hear me without.
It seems like my voice is there, but really really quite.
I was using Viper One till today and it happened between 5.60 and 5.70, but today I changed the rom to see whether it could be a rom problem and using now InsertCoin SixthSense 1.0.1.
My HTC One is unlocked, S-OFF and of course rooted... any idea, what could fix my really quite voice, instead of screaming or using the speaker the whole time? I don't like it, when everybody can hear me talking on the phone, I'm no Eric Cartman.
Record some video with very loud sounds. Try blowing or whistling directly into the mic . Sounds crazy but it has worked for others.

Will try both "fixes" tomorrow.
So it's a already known problem for some users?
Btw: I tried to use Shazam and it also nearly identifies no music, even if it is in front of the speaker. So it has to be something with the normal mic. But why does it work flawlessly, when talking with the speaker enabled?
I suppose it could affect all mic functions. I personally experienced this with phone calls and personally fixed it with loud recordings (as did others), i didn't check shazam ..

Okay tried it a few days ago with whistling directly into the mic and it didn't fixed my problem.
So I decided to try the extremely loud recording and it sadly also didn't worked.
But I found out, that it has been gotten worse than before. My recordings on 29.03 went with a few quite whistles, but my recording yesterday couldn't record any whistle at all and only got music, after I increased the volume to +300 and it's still really quite.
I also tried to flash a new radio and kernel, none of them fixed anything.
So I guess, flashing back to stock and bringing it to a repair station is the last chance I have?

[Q] Is there an App that will boost microphone gain on speakerphone?

Just got my Nexus 6 last week, and spent a few days rooting, ROMing, installing apps and setting up those apps. One app I use is "Ventriloid" to talk on Ventrilo servers with friends. The microphone volume is way super low. Even with Ventriloid's microphone gain, it's still horribly low and doesn't do much. I'm assuming this is going to be the case with speakerphone as well since I searched this topic and others had the same issue.
Is there an audio App that I can install to manually boost the microphone gain? In the mean time, I'm going to check out a couple stores and see if the display models have the same issue. This could be a deal-breaker for me since I use speakerphone and Ventriloid a lot. But I do like this phone and hate to sell it.
I can't believe this issue made it past Q/A.
