ViPER4Android is just amazing experience for music lovers and greatly improves performance of our DAC. Original thread in Development and Hacking / Android Software Development received more than two milion views and OP @zhuhang did amazing presentation in first couple posts. V4A developer is @viper520.
Check it out! http://forum.xda-developers.com/show....php?t=2191223

You got to be rooted and have SuperSU on your G2. It's reported that SuperSU plays nicely with ViPER4Android and Superuser could have some difficulties.
App will install drivers for you and make sdcard/ViPER4Android/Kernel folders in your main storage. Follow instructions from the app. Basically, just pick desired audio quality / battery consumption. Reboot. If ViPER4Android folders are not automatically created, see EDIT at the bottom of this post.
In sub-folder named Kernel extract IRS files from attachment (at the bottom of this post) or downloaded Starter Pack from OT. Reboot again. In order to see Convolver / Impulse Response (IRS) files, go to UI Setting and choose Expert option.
I removed some IRS files from original starter pack and cherry picked some more free IRS files from other packs.
Superb, free, studio quality, 6 (six) sets of IRS files in this thread by @BSDgeek_Jake;

Check out another great IRS thread by @zhuhang and if you feel like it you could purchase some of his premium IRS packs to support V4A development;

Here's another awesome irs thread by @Vinardo_ZzZ 2000;
http://forum.xda-developers.com/show...php?p=52976760
It's geared towards more advanced V4A users. Have fun!

Most music players work with default Normal setting. If you're still on Jelly Bean (4.2.2) and have problems with Google Play Music or stock LG Music Player playing local mp3's with headphones or thru speaker you'll need to edit build.prop files. Instuctions in post #218;
http://forum.xda-developers.com/show...php?p=47288003
If you have problems with driver installation when upgrading V4A to a newer version and V4A asks you to install drivers again and again, follow instructions in post#594 and #596;
http://forum.xda-developers.com/show...php?p=52053808
For KitKat users, who want to install V4A as system app, @reas0n wrote simple instructions... In addition, there are instructions on how to manually edit build.prop file if needed.
http://forum.xda-developers.com/show...php?p=53280511

Also, for KitKat users with custom recovery, you could flash attached files located in post #609. Those files will make proper build.prop edits, install V4A v2.3.3.0 in system/priv-app folder and install super quality audio driver. Before flashing, make sure you removed old driver and V4A FX app itself.

Wow, I'm definitely looking forward to trying this out. How did you find out about it? Can you change settings on the fly? I read some of the main thread, the auditory calibration sounds awesome, since my ears are different and I have trouble hearing high frequencies. That says coming soon for that feature, but damn this guy knows his stuff!

You got to be rooted and have SuperSU and BusyBox on your G2. It's reported that SuperSU plays nicely with ViPER4Android and Superuser could have some difficulties. You can install app(s) in couple ways and I chose easiest for me. Play Store.
Link https://play.google.com/store/apps/d...iper4android4x
Don't be afraid to install because description is in Chinese. If you want translation you could use desktop Chrome browser to translate into English. After installation everything is in English.
App will install drivers for you (G2 use CortexA8 with NEON) and make 2 folders in your SD card. Follow instructions from the app. Basically, just reboot. In sub-folder named Kernel extract IRS files from attachment or downloaded Starter Pack from OT. Reboot again. I removed some IRS files from original starter pack and cherry picked some more free IRS files from other packs.
Play Music and Shuttle+ works with default Normal setting. If you have problems with some other music apps try switching to back and forth with Compatible mode. Much more detailed instructions and explanations you could find in original thread.
Link, again http://forum.xda-developers.com/show....php?t=2191223

I believe that's it. Enjoy!

P. S. I can't attach right now because I'm using Tapatalk 4. I have option to attach a picture, not a file. I'll try later with something else. Use Starter Pack and(or) other packs. You'll find links in original thread.
EDIT; I attached zip file.


Been using this since i got root, and it really is amazing. Recommend it for everyone.

I StumbleUpon it. LOL. Yes, you can change settings on the fly. So much to explore and experiment. Don't be afraid to change some settings but be careful with volume control. Start with 40% and don't go over 50% in first couple of hours because some combination of settings will give you volume boost up to 8dB. Maybe even 10dB boost. I set speaker settings with 8dB boost so watching YouTube videos with 30% volume feels weird at first. Still exploring. Probably it will take days before I become familiar with every option.

Yes I know. However I have tried similar things in the past and the effects for BT never seemed to work. Hoping this one is different. Will report back after I try it.

im confused on where the kernel folder is to put the files. using es explorer im not seeing it but you said the sub folder was the kernel folder so what main folder am i looking for?

I checked on the site. i guess for some reason it isn't creating the 2 folders in storage for me after the reboot.

sd card/ViPER4Android/Kernel/xxx.irs
If you don't have these folders upon installation of apk make it manually

In the FX app, make sure convolver is ticked. Then press impulse response and it will tell you the folder is empty. It JUST created the folder you are missing. Go back to your file manager and copy the files there.
