You're very welcome. Guess that it works now?

---------- Post added at 01:06 PM ---------- Previous post was at 01:03 PM ----------

If you run it in Normal mode it will process on everything. Notifications, Youtube, MX Player, most music apps, or whatever. If you run Compatible mode it will only process in music apps. For our phone we can usually run it in Normal mode all the time on most ROMs. I actually haven't found one yet that you can't run it in Normal mode on. The only thing I've seen is Pandora doesn't seem to process. At least on the ROMs I've tried. That may be the case with most streaming services. I don't use Play or Spotify so not 100% sure about that.

I have a small problem with Flex 2.2 and Viper4Android 2.3.3

The installation was successful and ended up with no error. But when I start the Music App Viper4Android is not active. But when I start the player and start then the Viper4Android Control Panel it has a small interruption but then you will hear clearly the difference (Viper4Android is on)

Is there a way to fix that small problem?

Btw I installed the app in System/App

Thanks in Advance!
[G2 General] JRJ442:
Try putting the app in System/Priv-Apps instead. Sounds like the system is still killing V4a. In Priv-Apps it won't be able to do that.

Ok I've done the steps to load IRS profiles. Put the IRS files under /Viper4android/Kernel but with no luck and I even trued /Viper4android/Profiles with no luck so I tried to out the kernel folder under Profiles but still nothing is showing up. I even installed it in the Priv-app folder after the normal app folder under system and still not showing up.

So i'm running viper on a N7 Flo, on Savermod 4.4.2 rom, i turned on Music FX , (i couldn't disable direct volume control, said it wasn't supported in my rom?)

I then went to the vol section in Power Amp and there's no music fx switch..

This is uber important for me because i use the N7 as my car's deck. TY

---------- Post added at 10:50 PM ---------- Previous post was at 10:43 PM ----------

forgot to add more information

Deck is being run by a 3.5mm to RCA cable, to a 1000/1 JL audio Amp for my w7 sub, and a 400/4v2 JL amp 4channel to my tweets\speakers.

Just to give you an idea of the setup.
[G2 General] alex72:
Your ViPER4Android/Kernel folder must be in your main SD storage tree and check your spelling. It must appear as I typed above. And last thing, irs files should be placed in Kernel folder without any sub-folders. Just pure irs files. Hope it helps.

EDIT;

You can even do it automatically... Just read the last paragraph of the very first post (OP).
[G2 General] ffejy462:
Holy moly... All this time I've been wondering what the big deal was with irs files. I had downloaded a bunch of them, but I couldn't tell the difference and I just blamed it on Bluetooth, ear buds, hearing loss, etc. The whole time it was just because all the irs files were in a sub folder under kernel. Thanks! I must have done it when they were extracted...

---------- Post added at 08:46 AM ---------- Previous post was at 08:44 AM ----------

Oh and using it with power amp
[G2 General] alex72:
You said, in post on previous page, that you can't disable DVC in PowerAmp because your current ROM won't allow it. In order to use ViPER4Android with PowerAmp you must disable DVC. Is that simple. So solution could be to install ROM which will allow disabled DVC in PowerAmp or switch to a different music player, like Shuttle+ or GMMP for example.

Edit;

Did you try to run ViPER4Android in Compatible mode with PowerAmp? Maybe it will work this way.

Edit 2;

It looks like that your N7 ROM have some other audio enhancements and it's conflicting with V4A. If that is the case and above suggestion (to try Compatible mode) doesn't work, you gotta remove conflicting parts.

[G2 General] alex72:
Are we still taking about Nexus 7 ROMs? I guess CM and AOSP did something wrong with soundfx libraries in latest updates so I suggest you to replace it with libraries from older Nexus 7 ROM. As I told you, I am just guessing. You might have better support in Nexus 7 forums.

Quality

Do you lose the lg g2 high studio quality??

I always used v4a, but yesterday i uninstalled the driver to hear the diffrence and without v4a the audio is way better quality and the sound is more clear.

Is that only me?

I see that the v4a driver has a 48000 sample rate and the stock has 192000.
[G2 General] alex72:
You could just disable V4A, no need to un-install. In this comprehensive article you could find that high sample rate offers no real benefits and actually proves that 192000 is harmful for human hearing;

Hello everyone!

I`ve got a D802 Android Version 4.2.2 Stock Rom. Yesterday I rooted (using IOroot25r1). Everything went fine, so I used "Flashify" to install philz_touch_6.41.6-d802.zip. Everything was ok, i could start custom recovery and did a backup of the stock recovery via "Flashify".

Then I tried to install ViPER4Android (V4A FX v2.3.3.0). Hence I couldn't hear any difference i opened the build.prop via Root Explorer in the Text editor (setting it to read/write) and changed the following lines as written in the instructions on the hp (http://vipersaudio.com/blog/?page_id=52)

a. Open up /system/build.prop in text editor using any file explorer with root access.

b. Change the line (If you can’t find these lines, skip this step.)

– “Ipa.decode=true” to “lpa.decode=false”

– “tunnel.decode=true” to “tunnel.decode=false”

– “lpa.use-stagefright=true” to “lpa.use-stagefright=false”

Everything went fine and i rebooted... now my phone doesn't start Android any more. It shows the LG Logo and the LED is changing colors, but it doesn't boot up and the phone is getting very very hot... turned it off after 5 minutes. However I'm able to enter the recovery.

Can you please give me some advice, what to do? My main goal is to get the phone back to work again, but I would prefer not to loose all data, root etc (going back to stock)

Is it possible that the drivers and not the changes in the build.prob cause this problem?

I'm not sure how to access the file system in order to copy zips onto the sdcard only when recovery and download mode works...

Is it possible to read/write buil.prop from my PC, because i have made a backup of build.prop on the phone?

Ideas welcome! :(
[G2 General] alex72:
[MENTION=1153942]Patty85[/MENTION] Instalation of ViPER4Android driver has nothing to do with your softbrick. It's your unsuccessful manual build.prop edit. There are several things that could go wrong with manual build.prop edit and most common mistake is that you probably didn't set proper permissions. They should be 644 (rw-r--r--). There's a reason behind my recommendation to use build.prop editor from Play Store in post #218 (link to it in first post).

Anyway, good news is that you have custom recovery and that you are able to boot into it. Next steps should be to install adb drivers for your PC, connect with your phone booted in custom recovery (your device must be recognized in adb shell) mount /system and push back original build.prop file. If your device is not recognized in adb shell, your adb drivers are not installed correctly or your USB debugging is turned off in your phone or... There are so many things that could be wrong... I named just two most common.

It will be the best to post your problem in G2 Q&A, Help & Troubleshooting section because your problem will be solved much faster.

I know I didn't help much but I hope that you'll resolve this issue without much more trouble.
[G2 General] reas0n:
I have a minute so I can write a simple tutorial to get V4A working on our G2 without issues, [MENTION=652669]alex72[/MENTION] u can add it if ya want.

When installed like this, the app also never can be killed by Android RAM manager.

1. Download the latest V4A .apk for 4.x

2. Put the .apk in system/priv-app/ with permissions 644 rw-r--r-- (use Root Explorer, Root Browser or CM File Manager, or whatever, remember to mount system to R/W before doing 2. and 3. or to accept it when file manager will ask, it depends what program You use)

3. Copy these lines:

lpa.decode=false

lpa.releaselock=false

lpa.use-stagefright=false

tunnel.decode=false

tunnel.audiovideo.decode=false

...and put them in build.prop in system/ and save the file (check if it has 644 rw-r--r-- permissions after edit)

4. Reboot

5. Open V4A, choose quality and install library

6. Another reboot and You're done.

DOWN: [MENTION=3331309]rogconnect[/MENTION] It IS necessary, You must have LPA off.

DOWN2: [MENTION=652669]alex72[/MENTION] like this? :) and about build.prop, we MUST have LPA off, especially on Stock ROMs, they always have LPA on and it usually causes lags and bugs.
[G2 General] rogconnect:
Just a quick question.

Isn't necessary to change the build pro?

I have no problems installing V4A on my LS-980 and its drivers. Just make sure to have SuperSu installed.

[MENTION=3371513]reas0n[/MENTION] If you could edit your post a little to make it more novice friendly it would be great. Just add that you need to mount R/W system to allow changes to happen and to check build.prop file permissions (set it to 644 rw-r--r--) before step 4. Reboot. Thanks

Edit [MENTION=3371513]reas0n[/MENTION] I directly linked your tutorial in first post (OP). Thanks again!
[G2 General] alex72:
No, it's not required to change build.prop file but some music players won't work without build.prop edits. If your favorite music player doesn't work with ViPER4Android and you're unwilling to change to another, build.prop edits is a solution.

[G2 General] alex72:
There is no CPU selection in ViPER4Android FX app. Just choose driver audio quality. I prefer Super Quality.
[G2 General] tomc585:
I dont see an option for audio quality.

Whenever I open Viper4Android it says " In order to use viper4android, you need to install/update the V4A driver....,

Please choose your CPU.

*Without VFP (PXA920)

*With VFP

*CortexA8 with Neon

*CortexA9/15 with Neon
[G2 General] alex72:
You are probably trying to install older version of ViPER4Android FX app (2.2 or older) or XHiFi (stopped development). Anyway, here's the reference...

CPU-Driver List (Older V4A)

Note: This list just for reference, it is only needed for older V4A versions (v2.2.x and before)

Old CPU list:

OMAP3xxx, use “CortexA8 with NEON”

OMAP4xxx, use “CortexA9 with NEON”

MIUI 1/1S/2, use “CortexA8 with NEON”

Qualcomm MSM825x, use “CortexA8 with NEON”

Qualcomm MSM826x, use “CortexA8 with NEON”

Qualcomm MSM896x/APQ806x, use “CortexA8 with NEON”

Samsung Exynos, i9000, M9, use “CortexA8 with NEON”

Samsung Orion Dual-core, Galaxy S2, Note1, use “CortexA9 with NEON”

Samsung Orion Quad-core, Galaxy S3, Note2, use “CortexA9 with NEON”

MediaTek MTKSingle-core(max freq > 800MHz), use “CortexA8 with NEON”

MediaTek MTKDual-core, use “CortexA8 with NEON”

MediaTek MTKQuad-core, use “CortexA9 with NEON”

Huawei-HiSilicon Dual-core, use “CortexA8 with NEON”

Huawei-HiSilicon Quad-core, use “CortexA9 with NEON”

Nvidia Tegra2 Dual-core, Motorola Atrix, Xoom, use “Tegra2″

Nvidia Tegra3 Quad-core, use “CortexA9 with NEON”

Other, use “ARMv5TE”

Other Method to Determine

If you cannot find out which platform your phone is using, consider this:

1.*Qualcomm*CPU, freq lower than 800MHz choose ARMV5TE or Tegra2, freq higher than 800MHz(including dual/quad core) choose A8.

2.*Samsung*CPU, single core choose A8, dual/quad core choose A9.

3.*Huawei HiSilicon*CPU, single-core choose A8, dual/quad core choose A9.

4.*Any single-core*CPU, less than 1GHz choose ARMV5TE.

5.*Other*CPU, single-core choose A8, dual/quad core choose A9.

Edit;

Therefore, use CortexA8 with NEON.

Is there a way to disable Viper4Android for specific apps? When I listen to books on Audible it makes the narrator very bizarre sounding.

Hello guys...

Im wondering if most of you are using the Convolver and Viper-DDC effects at the same time. Im currently using the TRacks Compression.irs in Convolver and I'm trying to find a good DDC match but there is so many files and is not easy to find a combination that applies to different genres of music. I guess the only solution is to make a few profiles...
[G2 General] mannequin:
looking for a way to do this too (without the tasker though).
[G2 General] alex72:
I guess, most of us use either irs files in Convolver or DDC (if you have matching headphones) but not together because it beats the purpose. Some of us use neither, but use other effects like Fidelity Control, Headphone Surround+ and Firequalizer.
[G2 General] alex72:
It takes, literally, 2 seconds to launch V4A and un-tick Enable option (before you start Audible app). Even better solution is to make specific audio profile for it and load it before you start listening audio books.

If someone find a way to do it automatically, with Tasker or any other app, please post correct procedure for it.

What settings you find best really depends on your own personal listening preferences. You're better off to experiment and see what you think sounds best to your ears.

G2 Rooted Stock ROM - TWRP recovery

Hi! I have a LG D802 with stock ROM, rooted and TWRP recovery and I don't undestand how to install this app. I have read the entire post twice but I don't get it hot to do it correctly. Could you help me?
[G2 General] ffejy462:
The op is very well written, but probably is a bit overwhelming. I'll step by step, but leave out irs until you feel comfortable enough to come back to it (it's not necessary to have irs for Viper audio to function, but does add more complexity and functionality).

Download Viper. (you'll want one for 4.x)

http://vipersaudio.com/swupdate/viper4android/download.html

Move Viper apk from downloads folder to /system/priv-app folder with a file explorer with root privileges.

Set permissions to rw, r, r with file explorer.

Reboot.

Open Viper audio.

Select audio quality (I use super high or whatever it's called)

Reboot

It's now installed. Set Viper settings to your liking (there are more options if you select expert in ui setting in menu).

To test if it's processing:

Play music, open Viper, menu, driver status.

Some music players on some roms need to have settings adjusted for Viper to work and some players on some roms will need build.prop edits as well.

For example: I use poweramp. If you use poweramp, turn off dvc, eq, and select music fx in settings and eq page.

If you choose to use irs once you're setup, reread the op or we can help (the hard part is done once Viper is processing).
