When L will release, if Google doesn't fix anything, do you think we will just have to use the fix for Android L Preview ?
[Nexus 5 Android Development] chdloc:
Please PM me if you (or anyone else interested) are not scared away by running and modifying Tasker scripts,

shell scripts, and custom kernels; I'd be happy to set you up.

Note, that my mod is really a huge hack that may or may not work for others. At least until effectiveness is confirmed

by others I'd prefer to restrict support to PM.
[Nexus 5 Android Development] chdloc:
We will just have to wait and see how the final version of L deals with this and how this particular part of

the ROM differs from the L Preview.

Once Google releases the source code it should be easy to update my mod to work with L, if necessary.
[Nexus 5 Android Development] wigginst:
Worked wonders on my n5! Thanks! I teach music and marching bands for a living and the difference in recording quality is very noticeable!
[Nexus 5 Android Development] 5H00T4:
Man, seeing this is a general problem makes me kinda glad and fu**ing mad at the same time.

Glad because I am not the only one and the hardware is not the culprit, but mad that they haven't fixed it at all.:mad:

Unacceptable, isn't this supposed to be the flagship device?

Any news on whether they are planning to to fix this?

At the very least they must have the fix in the final version of Android L.

Everything else is a disgrace.

Is there any way to create more pressure?

Sending a tip to an Android news website so they can run a story?
[Nexus 5 Android Development] chdloc:
I'm starting to think that camcorder audio quality problems are not universal across all N5's. Otherwise I would expect this thread

to light up a lot more than it has been. My current guess is that the dual-microphone processing algorithms used for cellular voice

calling and camcorder use cases are "fatally" sensitive to microphone tolerances and we are in the minority of folks whose acoustic

front-ends barely meet (or even fail) the expected specs.

It is also possible that not all people are sensitive to (or bothered by) the distortions produced by the stock experience. To rule that

one out I'd be really interested in listening to sample recordings made by people who have no complaints with the audio quality of

their camcorder recordings.
[Nexus 5 Android Development] nappent:
Honestly most people just don't notice.
[Nexus 5 Android Development] nomancoolboy:
Exactly .

I rarely make phone calls ..

Btw the audio in camcorder is not as good as a flagship should have..

With the tweaks it does make a difference .. Btw can we enable stereo audio recording ? Just like the jishnu's nexus 5 cam mod .. I tried that in the beginning but then it was removed ..

(I think i haven't read OP properly)
[Nexus 5 Android Development] leeemans:
Thank you for this fix. I thought of replacing my phone for this software bug and then finally fixed it. I also compared with my previous video taken without flashing this fix and i guess the audio was little bit low. What was the problem actually and why was i not able to fix this issue with the official update??

Thanks for this fix.:good::good:

[Nexus 5 Android Development] Piereligio:
My doubt is... how will this interfere with fauxsound? Will it work? Will I have problems?
[Nexus 5 Android Development] chdloc:
I don't know anything about "fauxsound". I would not expect any problems unless "fauxsound" itself modifies the two relevant files.
[Nexus 5 Android Development] nappent:
I'm using a kernel with fauxsound and no issues here with the mod. And fauxsound is an kernel feature... this isn't.
[Nexus 5 Android Development] Piereligio:
I tested and I lost the microphone gain control via app. That's what happens. I think I'll use that one instead of this mod. It's more quick..
[Nexus 5 Android Development] WaxLarry:
Tried ubuntu touch for n5, in-call voice quality was awesome. Would be interesting if someone can port the involved files and configuration and finally make work our in-call sound also in android :good:

I notice that ubuntu is based on AOSP, so the port should not be difficult, but i haven't any idea which files are involved.

Just added a couple of thoughts to the quoted thread.

New Fix with Moderate Noise Suppression

Update (10/13/2014): Please visit the OP for the new fix

Disclaimer

: This new fix has not been fully tested, but it seems to work as expected for me on stock 4.4.4. While this new fix may work

on other AOSP-based ROMs (sans L Preview), it will certainly not work on CM-based ROMs.

Also, please note that I do not consider some of the necessary source code changes compliant with good coding practices.

That's why I'm very reluctant to make the source code available. However, I will be bringing my portion of the source code up to an (hopefully)

acceptable coding standard in case the upcoming public release of Android L does nothing to address the camcorder audio issue.
[Nexus 5 Android Development] marquimsp:
Is there a possibility that this latest mod could cause mm-qcamera-daemon issues? I've never experienced this problem until I installed this mod, and now camera doesn't work (can't connect) and this wakelock is overheating the phone.

Just asking, not accusing.
[Nexus 5 Android Development] chdloc:
Yes, I just noticed that as well plus hotword detection seems to be disabled now.

The only difference for me is that the camera still works.

I guess I got a little too excited and posted the new mod prematurely.

I've taken down the mod while I'm looking into the issues.

Thanks for reporting!
[Nexus 5 Android Development] marquimsp:
Thanks!

Now, how would a very very stupid person (let's call him "a friend of mine") who didn't backup the original files proceed?
[Nexus 5 Android Development] chdloc:
Tell your "friend" to copy the files in the attached archive to their respective location

and to make sure that all files remain world-readable.

If all files are copied, the phone will be back to stock 4.4.4.

If your "friend" is running anything but stock Android 4.4.4 he/she may need to

unpack the respective system.img file from the ROM to access the required files.

EDIT: the stock files can now be found here
[Nexus 5 Android Development] chdloc:
The new mod with moderate noise suppression is live again here, now with working hotword detection,

and (hopefully) absence of inexplicable mm-qcamera-daemon activity due to the mod.

Please re-read the post as I have edited it heavily, re-install the mod, and report back.

Once I get a number of positive feedbacks I will ask [MENTION=3163883]spacetaxi[/MENTION] to prepare an Aroma installer for added convenience.

I reverted to stock and this issue disappeared.

Cheers
[Nexus 5 Android Development] chdloc:
Interesting. I can reproduce the bug you are describing, but only with Poweramp.

Audio playback works fine with all other audio players that I've tested (MX Player, n7player, WavePad, Play Music).

Please try again, but use the attached library instead of the one installed by the Aroma package:

Unpack it, rename it as libaudioflinger.so, copy it to /system/lib, and make sure the permissions are set correctly.

Please report back and keep those bug reports coming! :good:

Edit: Going forward, the latest experimental version of libaudioflinger.so can be found here
[Nexus 5 Android Development] spacetaxi:
Unfortunately this does not help. :crying:

I've removed the installer of audio fix v3 from post #3 and replaced it with an updated build of the v2-installer. Additionally I've posted a reverter for audio fix v3, just in case.

I will post a new installer of the newer audio fix if the problems with PowerAmp are solved.
[Nexus 5 Android Development] Bl4ck3urn:
Did some investigation with V3 (which is not available anymore) in combination with PowerAMP.

If you turn off DVC (Direct Volume Control) there is sound.

Turn on: sound is gone
[Nexus 5 Android Development] chdloc:
Thanks for your investigative work!

Yes, I noticed programmatically that Poweramp uses an AOSP audio effect called "Volume" which currently interferes with the way I apply noise suppression. I'm currently investigating a solution.
[Nexus 5 Android Development] chdloc:
Experimental libraries

To all of you who are testing out my new mod with moderate noise suppression and are experiencing issues:

Going forward, this post will contain experimental libaudioflinger.so files that try to address problems mentioned in the thread

Note that the files posted here are to be used only in combination with the new version of the mod.

Installation instructions (the symbol ">" denotes a PC command line prompt, "$" the Android "user" shell, and "#" the Android root shell)

Install latest posted fix from the OP or via the Aroma installer from the third post

Download the attached archive

Unpack the archive libaudioflinger.so.experimental_vX_Y.gz

where the X is the current version of the "stable" mod and Y is the version of the current experimental library once the experimental library gets merged into the actual mod (OP or post #3), X gets incremented and Y reset to 1

you should now have a file called libaudioflinger.so.experimental_vX_Y

> adb push libaudioflinger.so.experimental_vX_Y /sdcard/libaudioflinger.so

> adb shell

$ su

give yourself root privileges, if necessary

# mount -w -o remount /system

# cp /system/lib/libaudioflinger.so /system/lib/libaudioflinger.so.backup

# cp /sdcard/libaudioflinger.so /system/lib/libaudioflinger.so

# chmod 644 /system/lib/libaudioflinger.so

# sync

# reboot

Update (10/14/2014): libaudioflinger.so.experimental_v6_1.gz tries to fix the "no TX audio" bug when using audio-capable communication apps like Viber, Google Hangouts, and Skype

Update (10/16/2014): libaudioflinger.so.experimental_v6_1.gz has been integrated into camcorder_audio_fix_v7.tar.gz, see OP, and hence has been removed

After copy Camcorder Audio Quality "Fix" files DSP manager force closing when want to play song in stock music player?
[Nexus 5 Android Development] chdloc:
Did you install v6 from here, i.e. camcorder_audio_fix_v6.tar.gz?

Version 3 (camcorder_audio_fix_v3.tar.gz) had issues with music player configurations that employ AOSP audio

effects, which sounds like what you are describing.

I understand that this thread has become somewhat disorganized with patches and fixes all over the place.

I will spend some time later today to make this thread, especially with respect to the OP, more coherent..
[Nexus 5 Android Development] slobo2712:
Exactly V6 copied files where they needs to be(12 dB).Installed Mahdi rom without this mod play song working well than installed same rom puted this mod DSP force close.
[Nexus 5 Android Development] chdloc:
First of all, does the original mod (the one without any noise suppression) work for you?

I'd be interested in taking a look at the relevant parts of your logcat.

I looked at the relevant libraries shipped with Mahdi Rom and they do seem to differ noticeably from AOSP Kitkat.

I also saw references to CM (e.g. /system/lib/soundfx/libcyanogen-dsp.so). I'm sure that my new mod will currently not work with CM

or CM-derived ROMs. What this means is that my mod likely needs to be merged with the respective source trees.

At this point, though, I'm just going to wait and see whether the public release of Android L fixes the poor camera audio quality.

In case Android L does nothing to fix this issue, I'll be happy to work with ROM developers to get my fix merged into their builds.

I can currently really only vouch for the new mod with adjustable noise suppression to work on stock KitKat as I had to make some

fundamental changes in libaudioflinger.so (and a trivial one in libaudiopreprocessing.so). Only ROMs that don't modify audioflinger

are currently able to support this mod. Unfortunately, the only way to make sure is to try it out (unless I spend a ridiculous amount of time

looking through source code).
[Nexus 5 Android Development] slobo2712:
Tnx for answer but I found solution its Viper4Android,and personaly i don't think they gonna fix it in new andorid.
[Nexus 5 Android Development] chdloc:
Not sure I'm following you. Are you saying that Viper4Android is preventing my mod from working on your phone?

Does my mod work for you if you disable/uninstall Viper4Android?
[Nexus 5 Android Development] slobo2712:
No man,both working well,problem was dsp menager and your mod...
[Nexus 5 Android Development] chdloc:
FYI, I just completely reworked the OP to (hopefully) make it more coherent and readable.

Please post your experience with (particularly the new version of) this mod.

I would like to keep the OP up-to-date with warnings on incompatibilities.
[Nexus 5 Android Development] indigobv:
Thank you!

Fix #2 is by far way better than the stock version. I've tested both versions (stock and fix #2) on a trip, and the results I've collected are undeniably in the favor of this mod. Especially videos taken on loud environments (e.g. waterfall) are unrecognisable with stock noise suppresion (if you couldn't see the video, you wouldn't know what you are actually listening to). It's just way worse than any video I've seen that has been recorded with a Nexus 5. But with this mod, it's simply amazing. I was reluctant at first because I usually record on quiet environments and I didn't notice the issue, but now it's a must have for me. Even on quiet environments I've noticed that some sounds don't fade in/out anymore, which is yet another reason to have it installed.

chdloc, I'd like to thank you for your hard work and time spent on developing this mod!

P.S. I haven't noticed any bugs so far. I used the 6dB version for my testing on Stock Android (4.4.4) and I also have Viper4Android as well as PowerAMP. The only thing I've seen is that Viper4Android needs a path for v4a_fx library in audio_effects.conf in order to work. It is added by the app when you install it. I thought I would mention that, if you intend to use Aroma installer and make an option for Viper4Android, you will probably need a separate version for audio_effects.conf.
[Nexus 5 Android Development] spacetaxi:
FYI, I've updated post #3 with a new "combined" aroma installer. Unfortunately there's no option regarding Viper4Android, as I'm not using it.
[Nexus 5 Android Development] leeemans:
i flashed the new combined_build1.zip. Wow!! this mod is really amazing and the audio was so clearly and i also tested with the stock music player app with the equalizer turned on and there is no problem at all. This mod works perfectly fine as in the previous mod when i turn on the equalizer the music stops playing and thank you for the amazing mod " chdloc and space taxi".
[Nexus 5 Android Development] adnan.selimagic:
After flashing combined_build1. zip -> options 2. with 6dB NS, I have bug in Viber! Whoever I call can not hear me clearly.

After, flashing option 1. with no NS everything is OK
[Nexus 5 Android Development] aeoveu:
While I'm not refuting your claim, I have to say that Viber isn't exactly perfect either - you either get distortions (the sound quality changing now and then), or you get a low volume overall (which is something I get when I receive/make a call - it's not as loud as Hangouts is, from what I've generally seen).

It would be helpful if somebody else could test it.
[Nexus 5 Android Development] adnan.selimagic:
I've tested it one more time and I must say it is 99% (on my stock Nexus 5) caused by option 2 (with 6dB NS)

1. without NS (option 1) -> I hear myself on another phone

2. reboot to recovery -> flash option 2 -> I can hear myself but voice isn't clear at all (with a lot of distortions)

3. reboot to recovery again -> flash option 1 -> voice is clear again

As aeoveu said, It would be helpful if somebody else could test it.
[Nexus 5 Android Development] chdloc:
That's what I was afraid of: Now there are issues with communications apps that request the same "noise suppression effect" as (now) the camcorder.

I had tested the new mod with two VoIP apps that I have (Bria and Media5-fone) and it worked fine. Until you mentioned Viber (which I don't use) I forgot to test the new Google Hangouts app and voila, audio does not work anymore as it, indeed, requests the built-in noise suppression, along with echo cancellation.

Until I come up with a solution, the new version of the mod does not work with many VoIP apps. Sorry...
[Nexus 5 Android Development] chdloc:
Experimental libaudioflinger.so library posted here, which tries to address the "no TX audio" bug when using voice communication apps like Viber, Google Hangouts, or Skype.

Please follow the installation instructions given in that post and report back.

I have seen one issue on my side which results in no RX audio on Hangouts in about 30% of calls.

Not sure whether this is a Network/Server/Hangouts issue, but I had the same issues with the stock libaudioflinger.so

Thanks!
[Nexus 5 Android Development] bushu16:
I tried your earlier fix and it worked perfect with Viber, Skype, Line and Fringe! Basically no issues over data call. However voice call (no Voip or data) still has some issues. That too in low network areas.

I will keep testing and update...

P.S Kindly ignore my signature
[Nexus 5 Android Development] chdloc:
With "earlier fix" are you referring to the one without the added noise suppression?

If so, I would not expect it to cause issues with any other app.

The problems that some have been experiencing are caused by the latest mod with added noise suppression.

The camcorder fix should have absolutely no effect on cellular voice calls as cellular calls

bypass the Android audio stack.

(You may be referring to the in-call audio fix that I PM'ed you a couple of weeks ago.)
[Nexus 5 Android Development] bushu16:
Yep, apologies for the confusion. You are right, I was referring to the in-call audio fix.
[Nexus 5 Android Development] chdloc:
Please find a new version of the mod, camcorder_audio_fix_v7.tar.gz, in the OP that (hopefully) fixes the poor or no TX audio bug first reported here.

A new Aroma installer should be available shortly.

[Nexus 5 Android Development] blinqipa:
Really? Sure about that?
[Nexus 5 Android Development] aeoveu:
I'm not sure if they are - since the new preview still sounds watery to me.
[Nexus 5 Android Development] Origin8:
I have the latest L preview and it still hises and has that horrible watery noise that they said they were going to fix so I don't think it's fixed yet. Maybe in the full build it will be fixed but it's still present in the latest L preview. Seeing as there's a significant change in L, I'm not sure how well this fix will work but I'll try it and comment back in a sec!

**Edit: Don't try this in the latest L preview or you will get boot loops for days! Hopefully chdloc can look into L preview in the future and help us out with that as well!
[Nexus 5 Android Development] varuntis1993:
Well yeah looks like I wrote that too early in excitement. Should have done more testing. First two videos which I recorded were pretty good, no watery effects but little bit of hissing but very less . 3rd one had underwater like noises. But yeah it certainly as improved but far from acceptable. :( I didn't try this mod on the preview. So stock preview files.
[Nexus 5 Android Development] chdloc:
Try the L-Preview mod for Preview 81C posted here. With some luck, the relevant files have not changed since the last Preview release. Note that this is only the "simple" fix without noise suppression.

If the final release of Lollipop still suffers from the camcorder audio problem, I will get to work as the sources become available.

Turn the tablet on and plug in to your usb port on PC and you should be able to access data on the tablet.

If you have a passcode then you have to guess where the dots/numbers are to unlock it to gain access to data.
