21 Jan 2013 (Alert – Illegal ViPER4Android Theft /ViPER4Android Clone)
Recently, we found an android PAID app very similar to ViPER4Android.
Judging by the screenshots, its definitely a copy of our app.
We will do an investigation on this following paid app.

Sound Tweaks by APPZOS [Free]

Please do not mistake this above app as ViPER4Android. ViPER4Android is always free. Do not fall for this and do not buy it.

ViPER4Android FX

FX is the main control panel of ViPER’s Audio with all popular ViPER’s Audio settings.

ViPER4Android XHiFi (Stopped)

XHiFi has fewer settings compare to FX. It has superior audio reconstruction which mainly used for restoring lossy audio quality.

FX Key Features

★ NEW: FET Compressor ★

New compressor / limiter simulating operation of FET circuits.

★ NEW: Quad-Channel Convolver ★

IRS support extends to 4-channels. *Requires special IRS files*

★ AnalogX ★

Richer and warmer sound by simulating the sound signature of pure class A amplifier. *v2.4.x and above+*

★ ViPER-DDC (Now Customizable!) ★

Enjoy near HIFI sound on your headphones. *Not all models supported*

★ Spectrum Extension ★

Make your music sound lossless with enhanced high frequencies.

★ x86 Platform Support ★

Viper4Android supports x86 (Atom/Core i3/i5/i7) platforms.

★ USB/Dock effect Support ★

ViPER4Android supports USB/Dock audio output.

★ Speaker Optimization ★

First effect for speakers. Try it yourself.

★ Channel Pan ★

Controls left/right channel output. It’s not very useful unless your headphone is an imbalance or faulty one side. It will be a cure for you.

★ Differential Surround / Haas Effect ★

This is an old feature which ViPER520 had removed from FX in early days.
But after many users requesting it, ViPER520 bring it back to FX
More info on Haas Effect: http://www.mixcoach.com/creating-dep…haas-effect-2/

★ ViPER Fidelity Control ★

★ ViPER Bass ★

With different bass modes, you can have greater bass experience than before!

★ ViPER Clarity ★

With the latest Clarity mode selection, you can balance up heavy bass with high clarity audio that you can never imagine before!

★ Headphone Surround+ (VHS+) ★

With this VHS+, V4A made its way to achieve great surround technologies for Android.

★ Auditory System Protection (Cure Tech+) ★

With normal audio system, listening for more than three hours will feel fatigue, dizzy, tinnitus, irritated and other symptoms.
This is a normal reaction, heavy bass and high volume could cause permanent damage to the human auditory system, but other phenomena can restore through resting.
Viper as a listening experience professional will not ignore this problem. Therefore put a lot of effort to study how to make a “Healing” sound technology, just a small success. But thinking on how to let users experience it.

★ Convolver ★

When an Impulse Response Sample(IRS) is loaded, V4A will process the sound to show the same characteristics of the loaded sample. Through Convolution, samples with effects such as equalizer, surround, reverberation, tube etc can be loaded.
Download and extract IRS files to <storage>/ViPER4Android/Kernel/<paste files here>

★ FX Compatible Mode (Only in 4.x) ★

Compatible Mode supports large variety of music players and the players’ own EQ/sound effects (system-provided/third party)
Therefore, you don’t have to select V4A in Sound Settings > Music Effects, choose anything other than V4A. Just run V4A app and the effects will be working with anything else.
1. In option, switch to Compatible Mode. Reboot, done.
2. In Sound Settings > Music Effects, choose other than V4A.
3. Run V4A app and configure the settings then the effects will work together with the one you chose in Sound Settings.

Last Update Log

Note: FX v2.3.2.5 onwards:
1. Fully support x86 platform, but not fully optimised yet. (Using VHS+/Convolver may increase battery usage)
2. Fully support true octa-core devices.
3. Correctly-installed Busybox is required before installing V4A.

If you see V4A installation pop-up loop, its probably due to incomplete root OR htc_audio_effects.conf
