ViPER4Android (V4A) Audio Effects Audio Mod
This isn't my work; I'm just riding on the coattails of devs, so....

So I've recently tried this audiomod that totally brings the sound alive on our device. You download the correct file for whichever Android version that you have, place a file in root, install 2 apps, and tweek the settings to your heart's desire. If your heart's confused, there's even a guide to help you along!

It works with any music player (I use it in conjunction with Poweramp), enhancing the sound without the strict need to buy expensive, bulky headphones or much busy work. There's even no need for animal sacrifices!

All joking aside, it's really does help with the sound and you should try it out.


Note: Root/Busybox required.

hey, spreading the word is great.

I'm not spreading the word as I have no idea what this mod brings to the table. I changed the title from "audio mod" as that' wasn't searchable and wouldn't help anyone that might be looking for info on this in the future.. Adding this name seemed to make the most sense.

I noticed that this mod uses a form of convolution. I know on a PC that can be very processor/memory intensive. Is it the same on the Android devices this works with? If it is, does it impact battery life much?

I am still prepping my new tab 2 7" (rooted and backed up) and will be trying this mod. As for cpu/mem/batt. loads, yes it uses much more. If you use both mods, your device has to be able to handle the load.

Here is more info on that area.

Thanks for the additional info. I haven't had a chance since this was first posted to fully read up on this but the dev does provide a ton of documentation. That should give me what I need to decide if this is something I want to do.

I'd be interested in your feedback once you get it up and running. I'm not really looking to try to squeeze the last few percent of audio goodness out my Galaxy 4.0 but if this works well other people might want to give it a shot.

If it uses significantly more CPU and memory power, then it might be too much for the SGPs to handle, with their single-core CPU and limited RAM. The dual-core tablets with 1GB of RAM would most likely make better use of it.

You probably right, Marv. The dev's listed minimum and recommended requirements are here http://forum.xda-developers.com/show....php?t=2191223. If memory serves the 4.0 would meet the minimum. No telling how it would perform but it should at least install and load.

Should mention I am trying this in Samsung Tab 2 7" not SGP's. Missing the sg5 for sure!

Got it installed (used ViPER4Android FX auto installer) and had to make the paths for the IR samples on the samsung tab 2 7" as it won't show hardly any OS paths at all. simply make the folders your self on the tab sd card.

Looks great!!

As for performance, I have not had time to play with it as I was working on a ZTE WARP all day on my buddies boost phone.

What I can tell so far is it will run every thing except phone calls (no phone modual on it, so I do not care). Has 3 settings to pick what you want to set it up for, speaker, head set or blue tooth and has enable/disable on each, so if battery is running low or you would rather they last longer, just do not enable it...

Guess it's time to play!
Ultimate Ears SuperFi 5 Extended Bass
Sennheiser cx300
1st to try out.

Then some external speakers both wired and BT.

I'll update, but I never used this device for sound/music before this mod.

UPDATE 1: Even tho I was able to make the given paths, the impulse response says the path is empty.
UPDATE 1A: Figured out we have to use a file manager to work with jelly bean OS or at least with JB 4.1.1. Astro came thru with flying colors and I was able to copy and paste the IR Samples and folders into the Tabs main mem. card.

UPDATE 2: It is a MUST-HAVE mod no doubt about it! Has 17 up front functions with PLENTY of tweaks after you select any of the up front selections. the battery issue still remains a question as for how long it will take to drain yours. There are too many variables to try to predict because of the amount of up front options to turn on or not and of coarse if you rooted or not so you have full control over what is running with your system and draining the battery as well or not. Titainium Back Up lets you "freeze" any thing so it can't be a battery drain factor. Lucky patcher for adds, start up manager to control what can run when you want some thing to run and not always run like many apps do.
Here's a good link on that area.

I have no idea why any one into music would not want to use this mod. It is switchable between the stock DAC and this one and this one you can shut off and save even more battery than the stock one would use.

Thanks a TON to alljokingaside for the heads up. I owe ya a beer ;)

It doesn't matter what you use for play back its all MUCH better with the mod in place.

No prob.

It does use more- it'd have to- but i haven't noticed a significant drain when it's in use. The payback in terms of audio is amazing. Not only in terms of volume (I was using Poweramp 2.4, the version before they fixed the volume bug, because it was LOUDER; I've recently updated) but in terms of quality. The music sounds alive. I use the stock earbuds (they're good enough for me) so I imagine that on an actual set of headphones, it's be amazing.

They have versions for GB, ICS, and JB.
