Viper4android mod/app to Enhance Your music experience



                You might be having costliest cellphones,  but problem with an android smartphones is its poor audio quality.  So developers are constantly working hard to improve the audio quality of an android phone.  One mod I had discussed in my earlier blog called Xtrememusic mod. You can also try this mod if you have a rooted phone. But there’s an one more audio app called Viper4android and is absolutely  free to install on any rooted Android device.  This app is far better than any other app on the playstore and is developed by Zhuhang.

                  Viper4Android is gaining it’s popularity and it has been downloaded by millions of android users. Now VIper4Android mod has been updated to work on Android 5.0 Lollipop. Viper's audio is excellent in terms of clarity with its unique ViPER Clarity and XHiFi technology. It also improves bass with its dynamic bass and Viper bass and XHiFi technology.

                 Besides, surround sound experience had never been better without ViPER’s Surround Settings including Field Surround, Differential Surround (Haas Effect) and Virtual Headphone Surround+.

 Viper4Android Features
  •     Playback Gain Control
  •     Viper-DDC
  •     Spectrum Extension
  •     FireEqualizer
  •     Convolver
  •     Differential Surround
  •     Headphone Surround+

  •     Tube Sound 
  •     Fidelity Control 
  •     Auditory System Protection
        Below are the main features you can go through
  • Playback Gain Control : A Plyback gain control makes the headphone sound quieter or louder, even when the phone volume is set to max.
  • Viper-DDC : Viper DDC will produce a balanced audio response from your headphones, which means the lows, mid and highs do not cross each other. 
  • Spectrum Extension : Encodes the higher sound spectrum differently than the lower part. A different approach on the replication of the higher spectrum, gives us a more detailed sound.
  • Convolver : Best features of Viper4Android, and also the most battery hungry. Enables to use a IRS (Input Response Sample) through convolution. Which basically is a sound processor, playing back in real time the characteristics of the sample.  To use it you will need IRS samples, which you can find here. Put them into SDcard/ViPER4Android/Kernel  to work.
  •  Differential Surround : It basically differentiates the sound between two ears i.e delays the sound from one ear to another ear.
  • Headphone Surround+ : Here you can select 5 different types of effect levels, where each level gives you the different surround experience.
  • Reverberation : Simulates sound being reflected from objects. With it we can replicate sound as if we were in a room, while we listen to music on our headphones.
  • Fidelity Control : Gives us control over Viper Bass and Viper Clarity. With them, you can add bass via different modes and frequencies and also make the sound clearer. It works really well on lower bit rates.
