Mic recording distortion, due to hardware auto gain

One picture is worth a thousand words
Recorded with Tapemachine. Same conditions, same audio source, same settings... The only difference is hardware autogain control enabled on first sample, and disabled on the second one
How to disable it during video recording? No idea yet

that's a good improvement,maybe supercurio knows how to do it.that would be awesome for a good video recordings.

At least we now know the problem. Very good work.

Hmm i am really waithing for this fix. recording is HD is quite cool and good quality but its useless because the sound always go's bad because its recorded to loud.

New info:
AudioHardwareInterface: AudioHardwareBase::setParamenters(downgain=0)
That's how Tapemachine switch off hardware auto-gain
And auto-gain off seems only to work with mic set to front (AudioSource: VOICE_RECOGNITION)
Thanks to aLogcat app

hohoho. Now we just need someone with the knowledge to do that. Thanks rafalense for find out this

Don't forget that it needs those settings to be optimised for audio calls. Most likely, with theses settings, while in call, the audio will catch more of the surrounding than the vocal itself.`
So the best way for this to works would be to make an apps that does the command then goes dormant. Then you can record whatever and, when done, disable and close the dormant app (kinda like TrackerBooster)
BTW, don't forget that you're recording with a crappy built in microphone from a smartphone. I'll try to do the same with an external microphone to see.

I own both the Galaxy S and the Samsung Wave s8500.... And, i gotta say, that the Wave has MUCH better sound when recording video at 720p + Its much better synced with the actual video... Maybe you could look at the Wave and how i manages sound? It has the Bada OS (unfortunately)

Hi !
That's something I'll fix soon using hardware auto-gain.
For now I'm working on a jitter issue and the gain is the next one in the TODO list
As the jitter one is quite difficult I cannot give ETA yet

Thanks a lot, supercurio, without you, our galaxy wouldn't be as good as it is.

any updates on this item yet? this would make recording video's so much better.

Try this kernel, mic gain issue seems to be solved, plus other sound improvements:

video bitrate is already quite high but higher audio bitrate might be a good improvement

Hardware is able to record @48000 and around 256Kbps, but video and audio are out-of-sync
My guess, something coded wrong in the driver, so lets see if voodoo sound new kernel fixes it, and then we will record hd video with hd audio as well
A did a test for you minutes ago, check audio info:

why do you think this fixes it.. from my readings that kernel does not muck with video recording rates or microphone gain...

Hardcores K12L?
Check yourself. I did, and mic distortion is reduced considerably

Also possible:
16000 - 22050 - 24000 - 32000 - 44100 - 48000 tested

How can you get the camera app to record at 44.1KHz?
Edit: Got it. Weird though, even though it's 44.1KHz, the cutoff frequency is 12.0KHz instead of 22.050KHz. Not much improvement over 8KHz cutoff, but better than nothing.

[Q] Low microphone volume

So after about an hour and a half of searching XDA and Google I have yet to find a resolution that doesn't involve me opening up my phone and cutting the rubber around my microphone. Allow me to explain.
Since I can remember - I got my S4 in December of last year - I've had problems with people hearing me, low record volumes and so on. I rooted and modded my phone almost immediately after receiving it and never really had the chance to test on stock TW, but this problem has persisted at *least* since I switched to KitKat about 2 months before it was pushed OTA via Carbon, Pac ROM, and Vanir. I have made it a regular habit of removing any DSP/preinstalled audio software and using Viper4A, but I was hoping to get some sort of lead before I flashed again, revert to stock TW, or took apart my phone. EDIT: I still have the exact same issue without V4A installed and using stock DSP/settings.
This problem was reported fairly commonly with the SII and the Nexus 4, but the methods I have tried to solve the situation (*#*#197328640#*#*; Trickster Mod, no physical blockage, mixer_paths.xml does not exist...) have yielded no results. I tested with TeamSpeak and Zello's outbound transmit volume and there's a dramatic difference, but how to adjust this on a system-wide level still eludes me. Google Now, Sound Recorder, SoundHound and other apps have difficulty with any sort of recognition even in ideal settings (eg. quiet environments). I had to virtually yell to set up Google Now's "Ok, Google" system-wide feature requiring me to hold the device at arm's length.
I'm posting because I haven't seen any issues of this nature reported for the S4. Could anyone point me in the right direction? Kernel tweaks? File modification I'm missing? Anything?

Bump. I still have not been able to find a resolution to this issue.

Lollipop 5.0.2 two annyoing issues - headphones profiles and editing entered words

I suppose the problem exists for all 5.0.2 versions that have been released so far. Obviously I didn’t check all of them by myself, only the versions without operator customization (Central Europe, Nordic Combined, etc.).
The usage of headphones profiles in the sound settings is impossible. Those profiles shift automatically (I guess they reset to the general profile) while changing a track (I noticed this doesn’t happen always and what is most odd, always when I come back to the previous track, the profile resets) doesn’t matter if I’m using Walkman, Spotify or Deezer. Additionally, when I choose a random profile, its settings is random as well (for example settings for MH1C is not always available under MH1C, it changes randomly during such reset) it’s hearable when changing a profile while listening to some track. It’s a total mess.
The other thing is a bug in system keyboard. Probably it’s a matter of the language chosen (I chose polish)- didn’t check that though. When the keyboard is extended and I click on a word which I want to edit, the cursor moves to the end of the word, and it’s necessary to tap on the word again to cause the cursor stay where I want it. Is this a new functionality of Lollipop? It didn’t appear in KitKat.
Do you have some suggestions how those issues. Is somebody going to report them to Sony? Maybe some version that isn’t affected.

If you have Root, installing Viper should eliminate this.

No, I do not use root, and I think I do not need it.
But this is a workaround. I think, that stock music settings are great so I want to use it on LP too, not only on KK. I love LP design, functionality and all of it features. Now I must use KK again cause of this stupid problems...
Someone noticed this issues? On Z3C, or Z3?
Maybe some root workaround, without installing other music settings?

You are right, I noticed this issue too. Profile switching is inconsistent. Also, audio effects aren't applied automatically on tracks, you need to disable-reenabled them in Sound Effects menu, and do that for each new track (not always, like you said). The Sony SW Audio Effects are basically broken.

So what we can do with it? I really want to use Lollipop again, but I need music app and sound quality working flawless to be satisfied.... Maybe some root solution? Someone, please?
Also this is strange that there are only two of us, who cares about this issue. On the biggest android forum in the world... Sony Z3C audio quality is superb - I does not believe that there are no persons who uses their phones to listen music in great audio quality... I don't want to change my earphones only because it is not playing as good as it should on general audio settings. XBA-3 are great and sounds brilliant on MH1C profile. So I NEED IT to work on Lollipop!
Where are you, guys? Any support is needed asap!

I have an MH1c and the profile is useless for me now :'(

I recognize the edit issueon my lollipop. When placing the cursor in the middle of a word, it jumps to the end when you start typing. Very annoying :|

I don't use headphones profiles, so can't help in this regard.
Checked the edit function. First - it's specific to the system keyboard, second - it has a very consistent behavior, which leads me to believe that it's not a bug, but a feature. First press on the word is not for editing it, but rather for replacing it from a set of auto-completion options shown when you type - the same set shows up when you press the word after it's already typed. The second press is getting you to editing the word letter-by-letter. I've tried changing the autocorrect options, and when auto-completion suggestions are completely disabled - this feature is disabled too.
It can actually be useful in its current form, though I can definitely understand the need to have a switch to get it disabled without disabling auto-completion suggestions.

You mean feature of Xperia Keybord on Lollipop? Lollipop has different version of keyboard than KitKat? Can someone check this? On KK I've got 6.4.A.1.54 Xperia Keyboard. I am curious, if there is different version of keyboard on LP - is there a possibility to install keyboard from KK (without root) and will "the bug" still be present?
This thing - as a "feature" - is something doesn't make sense. On KK you can also change typed word to other from suggestions and - at the same time - you can edit if from where you tap it. Why the hell user has to touch the word again?

Not sure why, but I don't use a system keyboard - I use Smart Keyboard Pro. This "feature" isn't a part of the OS - it only happens when working with Xperia keyboard, with a custom keyboard it isn't happening.

While I agree with you that this is an issue, and if they have the functionality available it SHOULD be working as intended...
If you care about audio fidelity so much, you shouldn't be using an equalizer in the first place, you should buy good headphones, that have been correctly tuned -- either to produce the correct sound or to produce the frequency response you most like. On the fly software equalization is never the answer.
Most people don't care about the issue so much, and audiophiles will have the correct equipment. That's why no one else seems upset at this.
---
As for the keyboard, it is most certainly the way sony designed this new keyboard to work. It's not an defect, it's how it works. Try google keyboard, swiftkey, fleksy. I've used all of they and any one is far superior to the xperia keyboard -- the beauty of android is that you can customize what you don't like.

Believe me, I am know what I am doing and what I am using.
My headphones works good with Z3C on general profile and without any equalizations (by the way, Z3C has great audio quality, very simillar to eg. Sony ZX1 or Sony A15 audio players). But with MH1C profile works greater than good - it is sounds excellent. This is not an equipment issue thread.

No Xloud, Decreased overall loudness/Volumes.
I am also getting Sound Problems after the Lollipop Update.
1. The Xloud Feature has disappeared from the sound settings and playing music through internal speakers is so terrible, makes sound like coming from a very cheap phone.
2. The loudness has decreased a lot now. I think that Sony have changed the volume levels. I remember that in kitkat volume at lvl 1 was high enough to be audible easily and at max volume, it was pretty high, but now the volume at the minimum level is barely heard even through headpones. The sound i am getting now at max level in LP was at a level less volume in KK.
3. Yes, there is headphones selection problem now in LP, but you can just get the type of sound you need be selecting different ones. For example, if you want to listen to sound for Noice Cancellation headphones, then select those and then select any other to get the NC sound exactly same which came in KitKat firmware. The fact is that you will get the audio type which headphones you have selected previously.
Rest I am not getting any major issue.
even my friend who has xperia Z2 have same problems. I think Sony have used same basics for all lollipop updates.

If the stock eq isn't behaving, replace it with Viper:

Viper can up volume, as well. It's not as good as a dedicated headphone/dac would be, but it definitely does the job.

You mean, that If I chose MH1c profile, change it to another and save settings (go back) - while listening music it will automatically change back to MH1c setting? Not some random profile, or general profile?

The selection does not change, but the sound becomes as that of general headphones profile. I have even updated firmware to 23.1.A.1.28 but still all tge sound issues are there. Maybe in future firmware they will fix it.

Random Actions in Default Music App?

I haven't been using the default music app because randomly it does an action after a while of playback, pretty much every few minutes; back, forward, pause, whatever, it random action just randomly happens. I've wondered if I somehow accidentally used some sort of gesture or touched the screen, but it happens when the screen is off as well and there doesn't seem to be any gesture that would affect the music app anyway. Does anyone have any idea what can be causing this?
I've been using PowerAmp which doesn't seem to support the A7's DAC. I have it set to 24 bit sound in the last Alpha of PowerAmp (which was many months ago, I've given up on any update for PowerAmp ever arriving) but after side by side sample comparisons they do sound different. The problem is I'm not sure if there's a slight volume difference between programs causing that, or if it's some setting, or if it really is due to the output being done on different DACs resulting in the differences. Pocket Now's video stating it only outputs 16 bit downsampled audio has also stuck in my mind, but despite contacting them twice on different social media, they never responded. That's infuriating, making a bold statement like that, then never providing an explanation and leaving it ambiguous, never stating if the downsampling was at software level, firmware level, or anything.
So I basically have no idea what the hell is going on with the audio on this thing in any way, from software to hardware. That's incredibly frustrating considering the DAC is a major reason why I bought this phone instead of something else.
Edit: I forgot to ask, what software should I use to confirm what sort of bit rate depth the Axon 7 is outputting? I have a Sound Blaster ZxR for recording, so I can plug the A7 right into that.

I can't tell you how to test the depth of the audio coming from the cell. If you can't tell the difference is there any real point? It it just a matter of wanting the product you thought you were paying for?
For the other issue, a really simple thing you've probably done already is checking that ZTE's voice software isn't enabled for media control. An old S4 of mine would go "back" any time a sound remotely like a short "a" played.

I can tell a difference, on the default music player it sounds better, for example instruments sound more crisp and separated from the rest of the audio. The issue is that I can't tell if that perception of more crisp/separated sound is due to a slight difference of volume between programs which is difficult to perceive. Just to add to the confusion, different songs seem to have different volume levels on each player, which aren't consistent. For example song A may be louder on PowerAmp, but song B is louder on the stock player. In those cases where the songs are clearly different volumes (maybe 10% of the time) it makes it extremely difficult to tell which one sounds better to me. This is with all equalizer/Dolby settings disabled.
Humans easily mistake higher volume for "better" quality in various ways. That's really the reason for the "volume wars" or whatever it's called; music was often mastered with levels just blasting instead of balancing the audio properly.
What I was asking is what free program can I use to record audio from my phone to check if it's outputting 24 bit audio? But on that same note, yes, I suppose that would also let me directly measure volume as well.
As for the voice recognition, I'll try disabling that and see if it helps, but isn't that supposed to only work when holding down the back key anyway? Also, often when it did a random command like next or previous song, I was silent.

Ah, I see. Sorry to not be helpful whatsoever.

Hmm y somehow ZTE has volume differences. I also noticed it if i enable/disable Dolby Atmos.
But i also think that ZTE set up some DSP stuff on AK4490/61. I would be happy if there was an app which could change DSP etc settings of this DACs :/

I also noticed the fluctuating volume, for me it's via bluetooth.
It would progressively become quiet and when the next song starts it would scare the crap out of me (much louder), then repeat.
Rarely, it would continue to play randomly after I disconnect from bluetooth (not immediately after).
So it would be nice if someone found a good music player that takes advantage of the DACs and not exhibit random behavior -- alternatively if this was fixed that would also be good.
EDIT: For me, it happens in a certain volume range in the upper end. Anything lower or higher this does not happen.

Some kind of weird auto volume levelling while using bluetooth audio

Hi guys,
I am using bluetooth audio in my car and I noticed just after buying this phone, that when I set phone volume to 100% (in general, any volume above 67%), which I always do, since stock audio is not much powerful, volume changes rapidly during a song. To be more specific - I listen to electronic music and during every kick, volume goes down and up in the gaps between them, so it sounds like a wave. Higher frequencies or silent passages are loud as hell, lower bassy sounds are silent and this changes 2-3 times a second. It rips my ears off.
With my previous phones used in this car (LG G3, Zenfone Max 3), I never had this issue. I even tested some very cheap phones, every single one of them was ok, sound was not even distorted on max phone volume. On any bluetooth headphones it's the same case, so it's not car audio issue. Also when using corded headphones or aux, sound is perfectly fine as it should be.
What I already tried to fix it:
Messing with every setting in developer mode
Unpairing smart watch (just in case)
Tried loads of different audio players - with no EQ on, just flat
Reset to factory settings
Nothing helped. I lost almost a month with Asus "so called" support, I even shot a video for them with clear evidence what is happening. No help, except they tried to make an idiot of me. I get angry just thinking about that communication with them. Am I really the only one with this issue? I don't believe that warranty claim would solve anything and I really want to keep this phone.
Any help would be really appreciated. Thank you.

Try this, Goto Developer Options, activate the "Disable Absolute Volume" toggle (see screenshot). Disconnect and reconnect your Bluetooth connection. Hope it'll work out for you.

Actually, this was the very first thing I tried. Just to be sure, I did it once again together with disconnecting and reconnecting as well, nothing changed...

How about set whatever player you are using to be not battery optimized? I haven't been able to try any fix since I seldomly bluetooth connected to my car stereo. Or try, bluetooth volume control from Playstore maybe?

I am using JetAudio and optimization is turned off. Tried volume control you suggested, but it makes no difference. Sound is still messed up.

I use Shuttle as music player, bare in mind that every recording has a different mastering approach, thus volume levelling could be varied, especially on first pressed of classic records. Usually I am amplifying low signal wave records manually. But to keep away from such trouble, I suggest Spotify since it has normalizing feature, or turn on this feature if it is available in your music player.

I use poweramp.
It really help you. Give a try.
Do not use any third party equalizer app with Poweramp,use it's own eq .

I use CM's audiofx since it has somewhat subtle enhancement, aggressive sound tweak is nice but after 10 minutes or so, it tends to hurt my (old) ears. So most of the time I turn off EQ in order to preserve original sound, not that always works though, especially when it comes to mainstream records.

I am listening to my offline archive, not using Spotify etc. There is no way how the source file is affected - maybe one, but hundreds of tracks? Nope. If I have 67% volume or less set in my phone, sound is fine (but overall volume is low, since stock audio has no other amplifier. But when phone is set to 100%, no matter how loud I set car audio, sound gets wavy then. No other phone ever had this issue, I tried direct comparison as well.

I managed to do some test for a whole album on my way home, I could declare the volume level as well as connection was quite stable with no apparent bitrate drop. As a matter of fact it's superior than realme 2 pro which was suck big time in audio department. Although it is no comparison to my now dead lg V10, at this price point I can safely say I'm quite satisfied. The stereo is neither after market nor android auto.

I also have the same problem with my Bluetooth headphones (Sony WH CH400) which does not happen on my Redmi 3S (PE 9).
Songs can't hit the high frequencies and sound gets lowered down.
I googled and apparently its the stock Bluetooth stack that doesn't let the bitrate go above certain amount and needs some patching which Asus may not do.

Not yet, I read briefly the forum you advised, but I need to dig in a bit more. Anyway, even this the closest cause, I don't believe that this is issue is bitrate related (but I may be wrong). I still can hear high frequencies in music, but when bassy part comes in, it's like someone turns higher frequencies volume down, so you can hardly hear them. And when bass is gone, volume rises again to "match" volume of lower frequencies. I still did not apply for warranty claim, because according to the forum you posted, I don't want to give up early and try patching the stack (if I will be able to somehow). Nevertheless, I know exactly what reply I would receive after 30 days at after sales service - issue was not found.

Not yet, I read briefly the forum you advised, but I need to dig in a bit more. Anyway, even this the closest cause, I don't believe that this is issue is bitrate related (but I may be wrong). I still can hear high frequencies in music, but when bassy part comes in, it's like someone turns higher frequencies volume down, so you can hardly hear them. And when bass is gone, volume rises again to "match" volume of lower frequencies. I still did not apply for warranty claim, because according to the forum you posted, I don't want to give up early and try patching the stack (if I will be able to somehow). Nevertheless, I know exactly what reply I would receive after 30 days at after sales service - issue was not found.

I've requested a developer to implement this in his rom. Let's wait and hope the issue to be addressed by our amazing community, else our only hope is Asus Pie update.
PS. I have the exact issue, maybe I explained poorly. lol.

I've reported the bug on ZenTalk. I encourage everyone to report there too because it should be Asus' duty to fix this bug on stock rom.

Hey i found a way to tweak up things. The new omni player is on xda. It has a setting called output method. Select the OPEN SL ES. .ur problem will be solved.
