If you get FCs with V4A because of selecting an IRS, it's probably because of the "%" in the file name. You must rename them. Sorry for the inconvenience.
If an IRS doesn't produce any change, try the fix mentioned here
For fixing statusbar and notification drawer issues caused by the sound mod, go here
I've created a quick dirty program to rename WAV to IRS as I forgot to rename some of them. Download from my Google Drive IRS directory.
Alternatively, you can create a ".nomedia" file in /sdcard/ViPER4Android/Kernel so media players will not scan that folder.


More IRS to come!!! Feedbacks and critique greatly appreciated.



are greatly appreciated to support and motivate me to make more IRS
thank me by pressing the button, if you like my work. I spend a lot of time to provide these to you

Thanks for your donation guys!

IRS are only static effects. To activate the dynamics, get "eXtremeBeats" mod by Applicare Studios


Advanced Audio Enhancement Technologies - Elements Of Fidelity EX

Just brought Elements Of Fidelity back to life because I can't think of a better name
This one (EX Edition) is heavily tweaked and enhanced to improve audio better
The Pro Edition (lightweight version) will be released later

• I'm not responsible for any damage to your modded device/playback device/auditory system. USE AT YOUR OWN RISK!
• Please, make a backup before proceeding to flash this mod. There's no uninstaller at the moment
• Might not work on some HTC Sense & Samsung TouchWiz ROMs, resulting in crashes, bootloops or getting stuck at "Starting apps..."

DOWNLOAD from attachment below

Previously known as ASDPE
Older downloads are removed. If wanted, PM me or post on the thread

DO NOT flash Pre-Release versions if you are unsure

System Requirements:
• Android Jelly Bean or above
• Rooted, standard binaries or BusyBox
• Custom recovery (CWM, TWRP, etc - with AROMA Installer support)
• stock "linker" binary (optional)
• Standard runtime libraries (C, M, gabi++, C++ standard functions, etc)
• No other sound mods installed (especially sound mods that share the same files)
• No previous versions installed (optional, but recommended)
• Full system backup (optional, but strongly recommended)


Dolby Digital Plus - Ported from Lenovo Yoga 2 (E-AC3 codec & DTS Sound enhancement included)

E-AC3/DDP codec for MTK ported from Hisense

This is the latest version of Dolby Digital Plus sound enhancement, ported by me and modified to work across all Android 4.1+ ROMs, without the need of framework modifications. Just direct flashing.

• Latest version from Dolby Laboratories (I think)
• Signed with private key (testkey)
• Supports xHDPI displays (High-resolution images)
• Separate framework (custom permissions XML) - I created android.dolby.xml
• Separate tuning parameters (/system/dolby/ds1-default.xml) - You can mod it if you want
• Different UID from system (signature verification pass) - I'll add root access request if it requires elevated permissions

NOTE: I'm still working on this. It might not work on all devices (doesn't on mine either ). You may give it a try!
Low compatibility with KK ROMs

- Fix script errors
- Add support for x86 architecture
- Increase compatibility
- Fix Qualcomm codec
- Add codecs for Intel and Cortex processors

DOWNLOAD removed (ATM. Will add it back shortly after I fixed some issues)
