ViPER4Android – The Best Audio MOD for Android

There are tons of audio mods available for Android. But, ViPER4Android is the hands-down the most popular of all the audio mods available for Android at the moment. The V4A, short for ViPER4Android, was not really one of the best-looking apps and it has recently received a much needed visual overhaul with material design and everything.

Below are some of the features of what the V4A offers:

1. Playback Control: Control the output audio volume of Android by amplifying or abating it.
2. FET Compressor: Limits the FET circuits in Android to avoid any damage to audio hardware.
3. Viper-DDC: Pre-defined profiles for a large list of supported headphones to get the most out of them.
4. FIREqualizer: 10-band FIR (Finite Impulse Response) filter equalizer for refined control over every audio tone.
5. Viper Bass: Get the best control over Bass by customizing the frequency and using different modes – Natural, Pure Bass+ and Subwoofer.
6. Viper Clarity: Balance out the heavy bass and clear audio while listening to music.
