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.
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;

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;

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;

... or much simpler solution is to flash one of @guitardedhero zips. I tested a few and they work great. I'm using his zips for all my phones... I'll keep testing his zips with each update so I'll update post #783 accordingly.

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!

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.

This is just what the doctor ordered! Hope it works with BLUETOOTH.

It's got three main tabs. Settings for Headphone, Speaker and Bluetooth.

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.

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.

w000000000t!!
I was hoping there would be a sound enhancement for the G2 as I used nexus louder/noozxoide pro with my Gnex and it completely transformed the listening experience. I tried noozxoide pro with the G2 with so-so results so I'm excited to try this out. Thank you!! :good:

mine wont change. in driver status menu it says neon enabled: yes
enabled:no
status normal
processing no
i have v4A speakerfx is powered on checked
convolver is enabled checked
and xtra-loud is enabled check
i can also change the files in impulse response but nothing seems to change the sound at all.

It's a similar interface (ui) with a lot more options. And IRS files are main feature for me.

Thanks for the heads up on this Viper app. I will definitely try it out when I get my G2.
I am just curious if you ever did the "Increase Speaker Volume" fix in the thread below on top of installing ViperAndroid. I wonder if the combination of both the fixes will make the G2 speaker even better.
