Well everybody, as it has been asked many times now so i bring you the guide to increase the ""Microphone Gain"" on lollipop.
You will need to make some changes to the mixer_paths.xml content located in system/etc.
Open in Notepad++ or editor of choice and search for <path name="rec-main-mic">.
See below for what to edit,be careful not to adjust more than the value stated.
Save and set permissions to 644 or rw-r-r then reboot.

You "WILL" have to reflash the mod after each ROM update

Hope this helps :good:

Versions Explained:

10.x version is just a standard up-scaled mic and speaker gain..

11.x Same as 10.x but uses the internal speaker as well as loud speaker for sound playback :)

Ideally CM would take it serious and patch in upstream but they stand by "we use the same values as Samsung" :eek: which clearly is broken if ANY testing had been done.

Most people don't even catch the gain issue as the volume stands out a lot more. For me the fix comes with the xml and long term will probably be with a new phone.

Moto X Pure or Note 5 incoming.

Can you also make a file for better (very) loud recordings?

Can you also edit, that in normal recording volume its like on stock?

I will upload a "Stock" version but if you backup your original before flashing the zip then you can always reverse the changes ;). The recording mic gain is pretty loud in my mod, you can increase it more but I do not recommend this at all.

Sorry, I think I writed it a little bit wrong.
I mean a zip to record in loud places, not loud audiofiles. For example, at a concert
But the mic volume on phonecalls and peaceful surroundings should like stock, is this possible?

Okay, I tried the modified file for one day and it is a bit too loud for me. When I was driving and you had driving sound in the background while recording a voice message in WhatsApp it sounds very distorted.. When it is quiet around you it is very good. Is there anything I can do against this? Maybe lower the values a bit? So if I lower it do I have to lower all values?

The microphone is definitely not as good as my galaxy S2's microphone, that has a superb audio quality.. I guess Samsung makes savings on microphone quality or it is limited by settings..
I don't know if it would be helpful to send you the xml File of my S2 to compare the values. There I had installed CM11 and sound was great ;)

You can send it and I will compare the two files, I will take a look at lowering the values and see where we can improve the quality :), thanks for the feedback..

The mod does not affect the mic during phone calls, that remains untouched. I am looking into making it a little more audible in loud environments.

Damn I am on Android 4.4.4 (SlimSaber, a derivate of SlimKat) on my old Galaxy S2 and there I cannot find that file..
Do you know if it is maybe somewhere else under KitKat?

EDIT:
Okay I checked the new file, it is better but still a bit scratched in the peaks. What did you changed compared to the first file? I would also say, that the voice is a bit deeper than on my Galaxy S2 but I think that is not settings related but hardware ;)

regards

I dropped the "rec-high-gain" areas by 10 that was all so perhaps a little more fine tuning and we will have this bad boy perfect ;). Thanks for your testing,feedback and patience...

Good morning,

many thanks again for your work :)
I checked it again while driving today. It is better than with the first file but still a bit distorted in the peaks.
Volume is good but quality is still a bit "scratched"
I could also record a sound file in whatsapp and send it to you via Mail if you need it for further improvement ;)
If everything is ok I will share your thread in german android-hilfe forum and translate it to german :)

Btw. I found a very little error in the opener: "Back to Sock Zip" - I think you mean Stock Zip ;)

regards

is increasing the gain better for a quiet environment or a loud compared to stock?

I would say for a quiet environment because microphone gets more sensitive, in a lound environment it gets distorted but thejester123 is still optimizing the file and the one you can download right now is much better than the first one from yesterday :good:

    @j1gga84 my friend, thank you for your concern over my well-being and the email and PM did not go unnoticed I was just not in a position to reply at the time. I hope you are well and ready to flash a new update :)

    Lets celebrate :) here are the updates i promised before i was ill.

    all the changes from the xx.8 test builds merged, tweaked and optimized
    xml files compressed for minimal file size
    MOD will now survive ROM upgrades unless you "WIPE SYSTEM"
    Lowered a few values to reduce reported distortion.
