    AUDIO PROFILES

    This depends on you. set the profile the way you want your sound. keep the sound playing while setting the profile. An example below

    FX:
    <Headset>
    1. Master Power: ✔
    2. Playback Gain Control: ✘
    3. FIR Equalizer: ✘
    4. Convolver: ✔
    (ii) Impulse Response: Sony Xperia Rev2 ClearAudio+
    5. Field Surround: ✘
    6. Reverberation: ✘
    7. Dynamic System: ✘
    (iv) Tube Simulator(6N1J): ✘
    8. Auditory System Protection (Cure Tech+): ✔
    (ii) Select Binaural Level: Moderate

    XHIFI:
    1. Master Power: ✔
    2. Playback Gain Control: ✘
    3. FIR Equalizer: ✘
    4. Audio Reconstruction: ✔
    (ii) Hi Clarity: 50
    (iii) Lo Contour: 25

    NOTE: I RECOMMEND USING ONLY FX. YOU ARE FREE NOT TO INSTALL BOTH. USING BOTH CAUSES HIGH CPU USAGE. FX SEEMS BETTER AND HAS VARIOUS AUDIO EFFECTS.

    A BRIEF DESCRIPTION OF HOW THIS PERSONALLY WORKED FOR ME.
    -Your phone must be rooted.
    -install busybox, search playstore for busybox and install.
    -install viper4android as shown in the installation instruction above.
    -look up google for your phones CPU type, this will help you choose the driver to install.
    -reboot.
    -Open DSP manager in your phone and disable.
    -open your Google Play music, go to settings, Equalizer, and select Viper4Android as Always.
    -Enable Viper4Android. rock on!!!!!!

    Trouble Shooting
    When V4A not working for you. (Really No effect for some features, NOT CHECKING driver status)
    0. MAKE SURE YOU HAVE CHOSE THE CORRECT DRIVER. Refer OP.




    0. MAKE SURE YOU HAVE LATEST BUSYBOX INSTALLED. (4.3 - SuperSU 1.51 via recovery)




    0. Check 2nd post to modify build.prop lines. (If that line doesn't exist, skip this.)




    1. Uninstall driver, reboot. Reinstall driver, Choose correct driver, reboot.




    2. Don't use compatible mode yet, go to sound settings>music effects> and choose v4a(either fx or xhifi).



    >>>Test on several players.




    3. If not working, switch to compatible mode, reboot, go to sound settings>music effects> and select something else other than v4a.




    >>>Test on several players.



    4. If not working for some players, activate safe mode, reboot.




    >>>Test on those players. If no help, then the player is not compatible. Give up and use a different player for music.




    5. If V4A still not working, make sure you installed the correct apk for your android version. (2.3, 4.0~4.2, 4.3)




    - Which to install? FX or XHiFi or Both?



    A: FX has many audio effects, where as XHiFi mainly restores audio quality and only has Audio Reconstruction feature(not in FX).







    Althought FX has XHIFI clarity mode under ViPER Clarity, but its not as excellent as the XHIFI app itself. Therefore,



    If you like many effects(reverb, bass, surround) then choose FX, if you like clear audio/vocal and you have a good headset, choose XHiFi. You can also install both, but more CPU usage.
