Yes its not in the Magisk repo.Here you go https://xdaforums.com/pixel-xl/themes/mod-viper4android-2-3-4-0-2-5-0-5-t3737313 I strongly recommend version 2.3.4.0 , it works with no problems on my android 9 head unit. However 2.5.0.5 has a bug, ViPER Clarity needs to be selected after a reboot of the head unit.
[Android Apps and Games] AliMusa:
How do you install this? It's not showing up whether I try installing it via magisk or twrp
[Android Apps and Games] 3mel:
same again with the 2nd upload into magisk. obviously magisk has internet access to have gotten this far into the process.
[Android Apps and Games] fizzingbees:
Try viper4android v2.7.1.6 apk from xda labs.
[Android Apps and Games] 3mel:
I did try it, it's the same version thru magisk. to be honest I've tried so many installs recently I can't remember what didn't work for me in the labs upload.

Will this app support profile export/import? Because I would like to backup my configuration in case of changing device/ROM.
[Android Apps and Games] marciozomb13:
Why it should when everything is already saved locally? Just copy the folder to somewhere else you want and bingo. And in Android 10 case the data will be backed up in Google cloud.
[Android Apps and Games] MajinBoo17:
Yes you're right, can't install it on my phone too. Installed instead this one right now https://xdaforums.com/realme-5-pro/themes/magisk-module-share-audio-viperdolby-t4079569 ViperFX-0.95-ACDB.zip

But I see no files on the viper folder in the internal storage. So I have to re set everything after a ROM flash.
[Android Apps and Games] Wishmasterflo:
That is saved in /Android/Data/com.pittvandewitt.viperfx/files

It's viper4fx 2.7.6.1 version and it's Android 10. It works well before connecting to Android Auto, but it is in "no processing" state only if Android auto is connected. Please let me know if there is a workaround.
[Android Apps and Games] 3mel:
is there a way to take the DDC database file from previous versions of v4a and split it back into files 2.7 1.6 can use ? there was easily over 100 headphones in there and the two I've used were excellent.
[Android Apps and Games] knpk13:
Yes.

For the old pre-converted profiles: (extract it to the directory for DDC files and you should see them in the app)

https://zackptg5.com/downloads/V4A_VDCs.zip

To convert your own profiles: https://zackptg5.com/downloads/V4A-Profile-Converter.zip

For some reason the latest magisk module for viper is no longer on the magisk repo, which did all of this automatically. Zackptg5's website still has the module though. You may want to use that instead. I haven't checked if the file has changed (I last used it several months ago).

https://zackptg5.com/downloads/v4afx_v2.7.1.6.zip

Not sure why they changed it to VDC and removed the original DDC profiles (they include none out of the box in the new 2.7 version if you use the apk instead of zack's module). It just takes you to a telegram link that says the old versions were bad and that you can pay a few dollars for a new version. I haven't tried that myself as I recently switched phones and my new phone doesn't have a headphone jack rip.
[Android Apps and Games] BigAlf1265:
Thanks!

Great job, great app, great sound! Thanks to XDA! :good:
[Android Apps and Games] m.mohtashimsadiq:
Okay.

So oddly the legacy 4.4 version of the app works fine across every thing. But the 2.7 version works only with streaming apps, like Spotify, YouTube, JioSaavn, Pandora but does not work with with players that play local files. I have several players for different music types and non can process audio through viper.

Any idea how to fix this? Even tried making the viper app a system app.

As someone who is personally in contact with Jason, the original developer of Viper4Android, I'd just like to say,

1. No, this is not officially developed by the same person who originally developed the original V4A series, nor has he been officially authorized to continue the series.

2. Yes, I am still in contact with Jason.

3. No, it does not seem like Jason give a flying f**k what happens to V4A anymore. And looking at the improvements that have been made, I'd say the deWitt team is as welcome to inheriting the series as anybody would be. Given that they have also expressed that they are willing to change the naming convention if and when Jason requests it, my conclusion is this is as good as it gets in terms of continuation of the V4A "brand".

working great in LOS z5compact, install driver gake long time, so I restart my device and violaaa .. driver installed
[Android Apps and Games] Az56:
Sounds absolutely awesome ?

I have a bug though

Every time i exit and re-enter the viper app while playing playing music a toast appears (screenshot) and the convolver eq and output gain turn off amd i havw to manually switch them off and turn them on to work.

The volume ducks when system sounds play too and a similar toast appears but the effects arent disabled.

Im running android 8.1 resurrection remix on a oneplus 3t
[Android Apps and Games] Team_DeWitt:
Glad you like it.

That message usually pops up when another app is controlling the driver too. If you don't have another version of viper installed and the message still appears, please pm me using the format posted below the OP and I will see what I can do
[Android Apps and Games] Az56:
I had another version of viper app from the magisk module. I froze that version with titanium and rebooted. I still have the magisk module and the toast message doesnt appear anymore. But every time i open viper convolver get disabled and together with it the eq and output gain, the same problem as before. I'm guessing that's a problem ur working on as stated in the op?
[Android Apps and Games] VladAndreMano:
Why not uninstall the previous Viper module?

Uninstall that, then download this app from XDA Labs and install the driver directly from the app so you won't have duplicate apps.
[Android Apps and Games] Az56:
Yeah lemme try that

When i installed 2.6.0.0 it didn't ask for driver installation. Probably cus it detected the drivers from the magisk module.

I'll remove it and try

Update : Removed the module and tried installing driver from the app. The driver installed successfully but after reboot the driver still isn't installed
[Android Apps and Games] yung40oz84:
Every time I open the applic it stops processing... Then I have to disable, then reenable, but that doesn't always work. Then I have to go further and disable convolver, then reenable that for everything to start processing. If anything it should stop porcessing when closing not opening. Just reporting, let me know if need anything?
[Android Apps and Games] Zackptg5:
Try installing audio compatibility patch. For the convolver issue, you may need to toggle the on/off switch for it as a workaround for now. They're working on that bug :)
[Android Apps and Games] yung40oz84:
Alright thanks bud
[Android Apps and Games] Team_DeWitt:
There are still some issues regarding this yes, it is also stated in the known bugs post below the OP. It happens when the service is getting killed or when swiping the app out of the recents. We're currently still searching for a way to properly fix this.
[Android Apps and Games] yung40oz84:
Ok, sorry didn't see in the OP. Also, it happens for me when I open the application, that shouldn't be killing the service should it?
[Android Apps and Games] Team_DeWitt:
That should not happen every time when opening the app, no. If you can pm me using the bug report format stated below the OP, that would be very useful. I don't think a log is needed on this one though
[Android Apps and Games] yung40oz84:
I'm working now, I'll hook u up when I am done in a bit. Thanks.
[Android Apps and Games] yung40oz84:
Alright so here is recovery log and matlog. When open it stops processing. I seen in OP it says u have to click and unlick the convolver and I do have to do that but I have to go further by switching to another convolver and back to in I want. Just flipping the switch won't change convolver. This log should show it stop processing, I unselected and selected on switch, then convolver switch which don't work as I said.
[Android Apps and Games] Az56:
I have the same issue. Installing compatibility patch didn't fix the issue. One more problem was with the driver. It installed fine but after restarting it wasn't there. I installed the viper4android fx module from magisk repo and it fixed the driver issue. But the effects getting disabled is still there
[Android Apps and Games] pkWhistle:
Is there any point to using the old version 2.3.0.4. I don't see the super quality option anymore. Moreso, it says the 2

5.0.4 driver is recommended.

Is the 2.3.0.4 driver obsolete now?

Also minor visual request.

Would it be possible to have words captilized in the driver status. Statuses are all lower case.
[Android Apps and Games] Team_DeWitt:
No the 2.3.4.0 is not obsolete, the reason you don't see the quality options is because we only included the super quality version, not the other versions. We added recommended to the 2.5.0.4 driver because it is more battery efficient then the 2.3.4.0 driver. About your request, sure! We can do that.

Having a lot of issues with the driver as well on my OnePlus 3T across multiple 8.1 roms (They are all based on LineageOS).

I am using the APK version with Magisk installed, the Magisk package installs fine and it sometimes works without issues in the rare case the driver loads.

Most boots however the driver is not recognized causing the app to prompt another driver installation, this applies to both drivers.

Update: Looks like its rom dependant, roms based on LOS have the issue. This is also after uninstalling the MusicFX apk or with roms that never shipped it. On an AOSP based rom it works great every time.
[Android Apps and Games] DiamondJohn:
I have flashed a few Oreo ROM's on my device. I have found that its not LOS specific. I easily managed to get the latest Viper to work on ResurrectionRemix, but the driver install just sits forever on crDroid. Both are LOS based. Somewhere further up in this thread, someone else had the same behavior with crDroid on a different device.

Not sure if I did the same on my crDroid flash, but what worked on RR was:

Install Magisk

Install the APK

Download the driver.

Reboot.

I was a little surprised to find that it had auto installed/created a Magisk module for Viper. I remember searching for a Magisk module for the latest Viper in the downloads, but did not find one.
[Android Apps and Games] JoroBo:
Not sure if this would help for issues with Oreo because I am on Nougat TugaPower ROM (LOS based) with my Opo but it is worth a try. My ROM has Viper4Arise preinstalled (but you can install from Xda I believe) and I only downloaded Viper4Android FX Magisk Module (yes, there is one). After that the driver was working without any issues.

I have this problem when i use any bluetooth device: every time i recieve a notification the audio effects turn off, the notification sound plays and then the audio effects come back again causing an audio stuttering :/ Anyone knows how to fix this?
[Android Apps and Games] vertedintro:
Try installing the Audio Modification Library via Magisk if you have Magisk. This however probably happens because the notification is going through the Bluetooth device and your phone's speaker, which likely have different settings.

I'm having strange issue with "Spectrum Expansion" feature. When it is enabled and with even 0.1 value of it there is cracking sound moments and sound like dissapear for a moment while cracking (no clipping is enabled too) when the sound of a music getting intense. This problem for now was only checked with the following setup: Bluetooth speaker and lossy vorbis files.

Driver version 2.5.0.4. I will try to disabling other Bluetooth settings to see what will happen to this problem with enabled Spectrum Expansion.

With the Headphones there is no such problem with SE.
[Android Apps and Games] Lughnasadh:
Have you tried to toggle "Attach audio effects" on? Sometimes it needs to be toggled on or off (or even sometimes on then off) depending on what you are using to play music with.

Also, installing AML may help as it removes music_helper entirely and partially forces all apps to use session 0.

Using viper4android v2.7.1.6 on Samsung A70 here

It works fine for me

What I did was to install the magisk module from magisk manager and on top of that downloaded v2. 7.1.6 from xda labs.

I use player pro and it works fine with it during local file play.

Even es file manager and fx file manager build in media players work fine

Didn't had to freeze anything or install another module. Even with Samsung sound alive and Dolby atmos installed by factory.

Viper stops working after a while

As the title says, the viper driver stops working after a while. I'm not sure of the exact reason, but it stops on its own after a few hours after which I have to restart my phone to get it working again and the cycle repeats.

I'm using the 2.7.1.6 version from magisk on the POCO F1 with stock kernel and UI. Also added the ACP and AML modules but no music modules currently enabled. I've set viper as a system privileged app via systemize, so I don't think MIUI is terminating the process in the background.

Any help would be appreciated and thanks for your time.

[Android Apps and Games] paulCIA:
For anyone having trouble getting or keeping it installed, particularly on more recent Android builds, make sure you disable Play Protect in the Play Store settings. Cause, it used to just hassle me endlessly about V4A being an unsafe app, but you could just keep cancelling out the message every time and everything would keep working.

But now, not sure when it started but this must have been going on for at least a few months now, at some point I re-enabled play protect because some other app was refusing to run with it disabled, and until just now i didn't even notice two other things A. It stopped constantly hassling me about the V4A app, and B. V4A always stops working at some point even if i do manage to get it successfully installed.

Light bulb goes off in my head, I'll bet now instead of asking, Play Protect is just going ahead and silently disabling V4A and possibly trying not to allow it to install in the first place. Can't confirm because i haven't had it turned off very long, but everything sure seems to be working smoother with it disabled.

Definitely will not be installing any further monthly patches, if it ain't broke don't fix it. Ps happy Patch Tuesday everyone, make sure you disable patching, or I hope you did, cause all Patch Tuesday seems to do anymore is break the world and not actually improve anything!

This just further shows that Play Protect is garbage, all reputable antivirus comparing firms prove it in their tests. It's best to turn it off and use third-party software to get better protection and less problems like this. I can recommend Bitdefender Antivirus Free, which is way ahead in detecting threats and requires little resources.

I am not a technical guy. So I try attaching the screenshots which, I hope, shall convey my issue, but attachments dont get taken up as they are seen as 'bad request'. I'll try to describe the issue.

2. I click on the recommended driver and the screen keeps displaying buffering (the circle which keeps revolving as something 8s being downloaded).

3. Nothing happens after that.

4. I am currently using a Xiomi note 9 pro. System software is up-to-date.

Hope this helps. Have a great day.
