I dont understand it.. samsung sells video cameras ... if they sold one with the crapy audio of our phone no one would buy it and they wouldnt sell any.
So they know how to record acceptable audio.. Why cannot they tweek the audio settings when you start camera to record acceptable audio (assuming they need to be different than for a phone) and change back when exiting/using phone?
What are you comparing the audio recording to. I've seen people compare it to other phones online, and many reckoned it was quite good..
Also, you do realise that video cameras have a lot more space to work with right? The quality of todays smartphones video/audio/photos is magic considering the limited space available for sensors.

It's way too sensitive... I recorded a concert (and a drive in teh car) and the audio was crap. Distorted in the car, unbearable in concert (way distorted/nosiy... literally couldn't hear the actual music).
Saw other videos with phones and they were MUCH better (audio wise). And no, it wasn't an extremely loud concert.
I think the audio is really good for a phone this size. Are you comparing it to a bose system or what? Lol

I had the same problem with Omnia HD. The sound of videos was so poor too. It was resolved by firmware update, where the audio codec was updated.
Anyone knows if exists any firmware with an acceptable sound quality of recorded videos on i9000??

Playback is great, it is the recording that is a bit crazy, the mic is super sensitive.. hopefully they can adjust this in a firmware.
True i was in rally few days ago and recorded some videos from there , video quality was awesome but sound was terrible. Too sensitive mic!
Impressed by 720p capture, very disappointed with the audio.
Case in point: Recording as of today: youtube.com/watch?v=oQPov5mUTm8
not loud inside at all, just some general background noise.
Using latest official firmware from Samsung JG4 (Optus Aus)
It has one mic, designed for minimising out ambient noise during a phone call, you can't really expect it to be good at recording a concert.
Bs my kids 5800 an my wives n 85 and other Nokia phones all recorded acceptable audio.

OP, your meaning of "audio" should be more carefully explained.
DO you mean:
1) Audio playback?
or
2) Audio recording?
My guess is #2. Yes, the microphone is quite sensitive. There were tons of people using the Samsung Omnia ( the prior generation android smartphone) who complained about the microphone NOT being sensitive enough. So Samsung decided to make the mic more sensitive.
I know it was discussed before but I just wanted to ask if there is a fix. I have turned all volume options to full and also used Audio Manager to set all of them to full. I can get good video recording quality but the sound is extremely low even if the external environment sound is too high.
I recorded my son at a concert where the volume was too high (of course) and I can hardly hear the music on the video. too bad.
I believe that the DHD records audio form the front of the device and so it misses some quality but still it's unacceptable to be that low.
Also the microphone records video audio at 32kbps bit rate, mono and 8KHz sampling rate, but the mic can record in better quality outside video recording with other software but for some reason it's like that while recording.
I think it could be to improve performance of video recording but who knows. I know it's really low and sub-standard but I don't think there's anything we can do......yet.
I think HTC follows their motto: "QUIETLY BRILLIANT"
Quiet everywhere.
That's the only thing that ****s me.

I would say software because the actual microphone can record in much better quality when you're just recording audio with some sort of a program.
Ok guys, I know that the audio recording is bad with the poor microphones inside the smartphone, but things go worse with an external mic.
I purchased high quality linear measurement and recording mic - Edutige EIM-003
When I started to record I was blown away with the crystal clear and 100% true audio recordings, but the bass was blown away. It records only mids and highs ?!?!?! Than I tried several other apps for video recordings, even lossless audio recorders. Nothing improved. So I went into pure CM10 Android 4.1.2 and again it was so bad... :crying:

1st off that eim003 is NOT a "high-quality linear measurement mic". high-quality linear measurement mics like those from dpa cost thousands of euros/dollars....heck any decent microphone costs $$$. and this microphone claims to do that for 35 euros?
secondly whenever you see beautiful ultra smooth frequency response graphs....those are just artistic lies. so dont believe any of it. real resonse graphs are really jaggy.
third ...the type of microphone it is....an omni...doesnt hype up the bass in any way. so if the source isnt bassy the recording wont be bassy. typical (non omni) vocal mics have something called proximity effect...iow the closer you hold the mic to the source...the bassier it gets. omni mics do not do this.
fourth it could be that the analog input on the phone is cutting the bass frequencies...because most of the time external mics on phones are meant to record the spoken voice...which shouldnt have bassy frequencies.
fifth it could just be that the speakers youre listening on are bass deficient and coupled with reason #3...well...
keep in mind most pop recordings add in the bass artificially.
sixth...I dont know if the n2 or s3 supports usb mics but that may be a path to try out...because it would bypass the audio path on the phone...and already hit the phone in digital.
hope this sheds some light...

Yup I know, I tried with other apps but none of them record bass frequencies like the stock app and recuding the gain removes the "color" of the music
Both of the suggestions you gave, sadly, aren't obtainable
as long as you get a clean recording you could add "color" later. even full blown $$$$$$$ mixes don't have that "sound" until they go to mastering (well most of the time). But really it sounds like what you need is multitrack capabilities in a small portable format. Best to invest in something like that instead of trying to make the shoe fit. If would be the next step down the path if you're serious about your music. .. which is sounds like you are.

All mics which connect via the headphone/mic TRRS connector have a mono input.
If you're happy with a mono recording of your band, then it may be ok for you
If you need to record using a pro mic with XLR connector, you can have a look at this small preamplifier:
http://www.ikmultimedia.com/products/irigpre/
I haven't tried it myself but it should work fine as it connects via the heaphone/mic port.
Does anyone know whether an external USB audio interface connected via an OTG cable works?
This would be the easiest solution to get high-quality recordings

Well this doesn't mean that we can't search a way to improve it
We should have USB audio interface support soon
http://www.kvraudio.com/forum/viewtopic.php?t=363102&sid=cb542f89bf6342383e9a8ca70521e6a5
This should allow you to connect _any_ microphone via a USB audio interface. Granted the audio interface will probably need to be mains powered.
But, it should also allow you to connect any standard USB mic dirctly via an OTG cable.
I was thinking of buying the iMic, but now that Davy has announced that his USB audio solution is almost complete, I think I will buy a Samson GoMic and use that instead. About the same level of portability, but the quality should be better.
If you don't already use it, you should check out his Audio Evolution app it is the best multi track recorder for Android by a long way.
The best idea might be to get a portable recorder with a couple of condenser mics on it. Then you would bypass the amps and dacs in the phone. You could then plubg the recorder in to the phone through usb host and import the tracks into your editor.

I admit that the phone is not for this job, but most of the competition records better sound. Beside that look at the impressive Nokia 808 with its Rich Recording crystal clear up to 130+db SPL and doesn't distort bass or etc...
I want to record good HI-FI sound from speakers, Live shows, etc... with low bass, clear mids and high, as like, as the sound is going from the speakers.
Look at this video recorded with Galaxy S2:
http://www.youtube.com/watch?v=B-Ys9SIJubc
Go to 1:50min and you will hear the impressive bass recorded.
Anyway, type in YouTube "EIM-003" and check the amazing acoustic recordings with this tiny mic. So YES, I think the problem is in our phones, unless I have fake mic...

not to be a downer but i went ahead and listened to the youtube link and a few other eim003 review videos...and to be honest they all sound pretty bad on my monitors over here...shrill and "essy" the impressive bass at 1:50 is just an illusion...the guy was cranking his car stereo which had a subwoofer. so with that in mind, the mic actually didn't pump out a lot of bass at all (compared to the amount of bass that i imagine was coming from his system). and remember, if you're just recording things acoustically, you typically aren't going to run into those artificial amounts of bass.
why doesn't the OP post up a sample recording so we have something to compare to....because honestly i didn't hear anything "great" from the eim003 sample videos...
Yes, after a few tests at my home HI-FI system, obviously you are right, but it is way better than stock mics and handles much more SPL.
BTW, I found a solution for improve the recording. Samsung has limited the input signal via HPF filter. I went into the conf files in system/etc and modified a few settings ther. Now it records more bass with stock mics and external one. I turned off the HPF filter and swtched it to "hi-fi" mode.
I used the S3 theme to do that. :good:
I think that the mic has a potential with a better preamp. It is firstly made for iDevices.
PS: If you think there is a better mic for this money, you can tell me.
The S4 and Note 3 have this issue, random and quite annoying popping when recording audio. I was really disappointed when I heard it on the Note 3! Hopefully it has been fixed on the S5!
Can anyone confirm whether or not it's there?

We'll see when I get mine. I'll let you know. But I think, it'll not be there for some S4 and Note 3, there's no popping when they record.
I've had numerous S4 and Note III samples through my hands and they have this issue. It's not an isolated issue. My Note II, HTC One, G2, iPhone 3/4/5s etc. have no such issues whatsoever. Normally I record video and audio separately but the argument (the best camera is the one you have with you) applies to a cell phone to capture things as they happen, unplanned. It's annoying to have these sounds in the audio.

weird i never experienced such thing on s3, n2, s4..
like I said, I've recorded plenty of guitar videos with my s4, through a Marshall dsl100 stack, which is loud and bassy, and it never ever ever had a problem with audio. it was always so clear and detailed, albeit only 128kbps. my g2 has that horrible underwater wishy-washy sound that makes the video camera unusable. I've never once seen audio artifacting on the s4. I had the snapdragon version, maybe you had the exynos?

Yes the problem is not with loud music like other devices which hard clip especially on kick drum hits...
This popping noise is most common when it's very quiet like recording at night with just the crickets outside...
And yes the audio was completely unusable on the G2 for me as well, if you recorded video in a loud cafe, no problem. But as soon as you went into a quiet area the gain levelers started getting really confused and there was all kinds of problems with sound. Ashame too since its camera (G2) was so nice...
Back to the S5, I have one in hand and while I have not put it through the gears my preliminary findings reveal a completely changed recording from the S4/Note3 hardware. The AGC does tend to bring up the levels higher when ambient sound changes but at least there's no nasty pops. The pops on the S4/Note3 can be removed with a click/decrackle plugin on most DAW software but they shouldn't be in there in the first place. This looks promising.
The video low light performance looks very good, I was shining a focused down aspheric torch (flashlight) around the pasture at long range and the screen was 100% black except where the beam was hitting objects at hundreds of yards away (barn, trees, etc.) and the detail looked shockingly good! I viewed the video on my Macbook Pro w/ retina display so it's a valid test.
Have not tried to see if it's IR filtered. Tonight we'll have the burn barrels going, that's the best IR test I know of without taking it to the lab.
These processors are so powerful it would be nice if they gave us the option of lossless audio recording and even a RAW photo option, although these tiny sensors would need a LOT of post processing to make the images useable. Still, however I always find that RAW+ Photoshop CS6 post processing looks better than the camera's aggressive post processing tuned for speed and convenience. With a 128GB microSD card, RAW+JPG would be fine.

That's seriously **** if audio's important. For me it is so now what...
What makes it worse is the LC V20 will come to Europe in midget form. Sheit!!
However, going back to the extensive gsmarena test:
Audio output is solid
When plugged into an active external amplifier, the Huawei Mate 9 posted excellent scores top to bottom, hinting at perfectly accurate audio reproduction. Its loudness was just above average so no real reasons for complaining here.
Headphones only cause a small drop in volume so it’s only average and a contained hike in stereo crosstalk. Overall the output remains very clear and while it’s not quite the best performer out there the Mate 9 certainly won’t let you down in any significant way.
http://www.gsmarena.com/huawei_mate_9-review-1520p7.php
Let me tell you that it wouldn't replace my external DAC/AMP. Mate 9 is a very good sounding compared to current competition. I wished if they could integrated a branded dac. The phone simply excels in every other aspect.
I think V20 is still the best in headphone quality as a stand alone. I haven't tested the V20 but I guess the specs say it all ?

Exactly what I was going to say, GSMArena made a deep test and the audio part seems "decent", which for me is more than enough. If you really care about audio, maybe LG V20 or Axon 7 would be the way to go.

Is the only review that says that audio is crap on Mate 9, besides is known that PocketNow, The Verge and BGR are Apple fans. If it's not Apple, is not good enough.

"The Mate 9's audio capabilities are equally beefy — up to a point. The phone combines a rear-firing loudspeaker with the main earpiece in a dual-speaker setup, similar to the HTC 10 or Huawei P9 Plus. At max volume level, the output is louder than you'd ever want it to be, which is great if you're showing someone a video in a crowded bar. But above around 50 percent volume, playback becomes increasingly tinny, with some distortion creeping in.
Fortunately, we've found that wired audio output is excellent with this phone. The 3.5mm jack (yep, it has one of those) is capable of driving demanding studio headphones with just as much power as the HTC 10."

i test with my pi audio mr2
it still carry the huawei signature sound
-full body
-bassy but not bloated
-frontal vocal
-kinda remind me of what makes fiio x5 different than x3
my only complaint:
-theres lack of decay or reverbation.for example, snare drum or any hollow instrument doesnt sound as hollow as it should
like many review such as gmarena said; its no dap replacement, but its one of the best offered by smartphone
lg v10 or v20 might be better
and imo, dap like fiio x3 sound better
According to this review, the Mate 9 is at the bottom of the barrel for flagship devices:
I mean for most people it will be good enough but no DAC/amp replacement. It won't be able to drive demanding headphones. One thing that I can say is that the measurements made by the reviewer does not match what the audio codec in the Kirin 960 is capable of. So unless there is a hardware bottleneck somewhere it would be possible to improve it through software if Huawei wanted to. High performance audio usually results in higher power consumption so the current state of the audio quality might be a compromise between performance and battery life.
