(Mod)(audio)Acdb from lg v20 for better audio on headphones and earphones

[yrahate7]

Hey guys,
I`ve been testing different acdb(Audio calibration database) for this phone, In order to make audio output greater on headphones without loss of quality.
So in my test, i found out that the acdb from LG V20 is the best for audio output.
In order to use this mod, simply download the file provided below and follow the instructions.
Instructions:-
1)Download the attachment(MTP_Headset_cal.zip) and extract it to get MTP_Headset_cal.acdb
2)use a root browser to navigate to /system/etc/acdb/
3)Backup the original MTP_Headset_cal.acdb to a safe location.
4)Replace the file with the file i provided MTP_Headset_cal.acdb.
5)Change the permissions of the file to Rw-r-r(0644).
6)Reboot the phone to enjoy the music.

Result:-
Audio sounds much clearer than before.
Bass throughput on the earphones is very great in comparison to the previous implementation.
Sound is much louder in comparison to the previous implementation by Cyanogen.
#edit
Now it gives my Ipod touch a run for its money.. ?

If anyone wants to know what an acdb is, It is a file which stores all the calibration for the hardware for audio card on the phone.

Will it work for Bluetooth headphones too?

I have`nt tested it on bluetooth headsets yet, However acording to my guess it wont work on bluetooth as there are seperate files for bluetooth which configure the audio output there.

That zip just contains one file just for headset but not for speaker from where we hear songs etc but phone's speaker contains files for everything.. why don't you paste all those files from lg?

Upload all its files if u can..

Upload all its files if u can..

When you replace all the files, the audio output becomes horrible. And the phone crashes most of the time then.

Jo file system partition me move karoge, Uski file permissions reheti hai.
Usko change karna hai Rw-r-r , nahi toh Aawaz hi nahi aayegi earphones se.

I have changed the default .acdb file with this and the sound quality has become superb but can't use headset durning calls as no sound is heard. All other applications work fine except the default phone app...

What to do?

Currently running on LOS 15.1

Same issue was with me. I found no fix cuz on all the roms i tested was the same so i just reverted back to the stock file.
