I'm trying to get viper working on android 10 on my OP3T as well. Same boot logo stuck issue. What does deleting post-fs-data.sh do and why do I need to delete it on Q?

I tried your solution and while my phone now boots, viper status shows abnormal and not processing. I'm using Poweramp and I tried disabling DVC, enabling compatibility mode, and toggling the session 0 switch in viper. Didn't work.

I tried the stock music app and toggling session 0 switch made viper work. Weird.

Edit: Disabling lineageos AudioFX seems to fix everything. Works with poweramp and other apps without any other changes.

So I'm using a realme 3 Pro running unofficial LOS 17 and the convolver doesn't seem to show any IRS files even though I've moved them into /storage/Viper4Android/Kernel. Any help?

Poco f1, using PE10 and latest magisk 20.1, installed the app, but installing drivers i got to bootloop, how do I uninstall the drivers to get out of the boot loop? I really dont want to flash everything again and setup my phone for the 4th time today...

EDIT: went to twrp, cause ****ing **** bootloop and deleted /data/media/viper4android and still nothing, where are the drivers installed, so i can clear those guys?

EDIT 2: went to twrp -> data -> adb ->magisk ->modules and deleted viper4android, worked
[Android Apps and Games] Benholder90:
When I try to install the driver it says installation failed at obtaining root access ...

What to do ?
[Android Apps and Games] tafkax:
I have magisk installed, after 10 seconds it automatically detected it work me and asked to grant permissions.
[Android Apps and Games] gavilan2010:
Yes if happen u just need to wait to grant root acces box appear them close kill viper them open again say install drivers this time will install and reboot and buyaaaaaa.working

But u need to wait. Take time the grant acces appear.

Hello everyne, I own a Oneplus 6T with OxygenOS 10.0.1, I followed this method:

https://www.the***********.com/install-viper4android-android-10-guide/?unapproved=16923&moderation-hash=34c09f222def1f40cb764607a66b2777#comment-16923.

At the end, the apps starts I can go in the menu and 5 second later stops automatically with the message: "Viper4Android FX has stopped", App Info or Close.

Have you got any solution ?

EDIT: There is no more sound on my phone now. Tried to uninstall, but nothing to do, it seems that the installation broke the audio driver... Will have to factory reset...
[Android Apps and Games] JBolho:
There is a rootless version that I think is flashable through TWRP (I don't know the details of the procedure), search for it on the thread (some 20 or so pages back at least)
[Android Apps and Games] Benholder90:
But in order to install or use twrp does the phone not need to be rooted?
[Android Apps and Games] JBolho:
Of course not. TWRP is just a custom recovery, you can have it and not have the system rooted. Needless to say, it needs an unlocked bootloader of course.

Search for rootless version on this thread, you'll have to flash a zip file available on the Dev website I think and install the apk.

Hey guys, just installed latest APK, but phone does not pass the boot logo on restart.

Tried to use the Rootless Installer from OrangeFox Recovery with no luck.

My phone details are:

Xiaomi Redmi Note 5

Magisk Rooted (don't know if core or full)

What's the path of the log file?

Thanks

Ok, sorted out.

Removed manually Viper4Android Module while in recovery.

The path is /data/adb/modules and the name of the directory is pretty self explanatory.

Once deleted the phone booted just fine.

Some kind of incompatibility, i presume.
[Android Apps and Games] knpk13:
It works, but does anyone know why I need to do this? Also any side effects?
[Android Apps and Games] shadowstep:
If it is working, then there aren't any side effects. ;) Also, that script basically uses magiskpolicy to inject the required SELinux rules that allow V4A to process/work fine in ROMs with SELinux Enforcing. If V4A is working fine without them, then you shouldn't be worried about removing it, it will cause no harm. :)
[Android Apps and Games] koboltzz:
Sorry to ask this question after I get everything working :)

Under which setting is the 'dynamic range compression' hidden? Also known as volume normalization. Since this app uses system language and it does not seem to be the best translation is used ;)

I find Viper breaks so many Google actions and also causes other unknown issues with lags etc.
[Android Apps and Games] Mr.FREE_Bird:
Don't think that's caused by ViPER4Android. I have it installed on several devices for years and never had any issues you described. Beside that I find your comment to be very vague, you don't provide any info about your device, how you installed ViPER4Android or how to reproduce your issues or when they occur. You might want to provide us a bit more info...

I'm getting an Error while Installing it over Magisk.

Using Pocophone F1, with Stock MIUI 11.0.5 on Android 9.

The Old ViPER4Android FX 2.5.0.5 (Legacy) works fine.

Before installing the new ViPER4Android I uninstalled the old drivers within the V4A app, after that I removed it with Magisk.

Restarted phone, and installed the new V4A, it looks like it installed without errors, but when I open V4A, I don't get any prompts.

The Driver Status just says " Abnormal ".
[Android Apps and Games] Joe199799:
Yea I made a new one for the X4's I'd have to reupload the preset. I'm pretty happy with it but I also use it in conjunction with a preset on the Jaybird app. I'd have to find everything I'll edit this comment with everything.

Jaybird preset is balanced (update) by Robbie Khan

IRS Files https://drive.google.com/file/d/1UmnX-08ZD5k9AMNYcRZEjhFujTNb32-A/view?usp=drivesdk

DDC Files

https://drive.google.com/file/d/1CPMwlr3D8p_QtY9xN-1_eLdVXl-Yk06H/view?usp=drivesdk

Jaybird preset https://drive.google.com/folderview?id=1OqgTq_mVrim372T7w66uPNK7pzxcp91m

Download the folder and put it in presets if it doesn't let you download the folder just put the xml file in a folder and it should work. As I said it's really dependent on that jaybird preset because I used that as a base.

It kicks in the bass department but it can go full volume with no problem and the bass doesn't drown out the rest but you can easily tone down the bass if it's too much for you. I listen to everything other than country so I've tested it on a wide range of music. I guess let me know what you think.

If anybody else is interested I have a preset for Jabra elite 65t's and I can make one for Powerbeats 3's
[Android Apps and Games] Deatn:

I'm interested in the Jabra 65t files. Thanks
[Android Apps and Games] Joe199799:
I have a very bare bones set up for them I can send that but it's nowhere as polished as my X4 preset, they are my brothers headphones I'll see if I can borrow them later to hammer out a more polished preset.

But here's the preset I have right now

https://drive.google.com/folderview?id=1-biLcFIKSf1iGmCoJNqJe8fyMWrjKbnx

I'll edit this comment when I make a better one.

I'd suggest downloading the IRS and DDC files from a few post back as the preset relies on them.

They are a little rough to make a preset for but he let me use them for a week and I daily drove that preset so I may have been cool with it. I honestly don't remember. Give it a shot and let me know what you think.

I don't know it takes on average like an hour or two to really nail down a preset, my Problem is I always feel it can be just a little better which means scrapping the preset I was using and starting over again from scratch. I have around 20 different presets for my X4's over the past year of owning them.

But sound is subjective, what sounds great to me could sound like s**t to you, but from the limited user base I've tested my presets on everybody has liked them.
[Android Apps and Games] Zilla0617:
How do I add it in viper?
[Android Apps and Games] Joe199799:
Download the folder if you can't download the folder download the XML and create a folder for it, put said folder in viper4android >presets (should be in your main storage) IRS and DDC files go in DDC and Kernel (IRS) folders respectfully. all three folders are in that viper4android parent folder.

Then go to viper hit presets and it should be called whatever the folder name is.
[Android Apps and Games] Zilla0617:
Wow...this blows my settings out the water. Can't wait to hear your improved version once you have a chance to tweak the settings. Thank you very much from a happy 65t owner

---------- Post added at 09:11 PM ---------- Previous post was at 08:14 PM ----------

Personally I feel this one is a lot better theres more depth and more bass/less tinny sounding. The preset is dependent on the bass boost preset on Jabra sound+ other then that you should be all good let me know what you think.

Hi there,

has anyone got Viper to work on android 10 yet?

I tried to install it on my HTC One M8 running LineageOS 17 both the magisk modules avaiable and the app from xda labs both ends in a non booting rom which then boots into fastboot and i have to remove the module through twrp file manager to get it booting again.

Haven´t tried any other devices yet since i expect similar results on other devices due to general incompatibility with android 10 as i´ve read on other threads...
[Android Apps and Games] Badger50:
I don't know if this will work on your particular device, however, it has worked for many, including my P2XL and P4XL. Might as well try :good::cool:

There is a fix shared on official Viper Telegram group.

https://drive.google.com/folderview?id=1-11mghaQ5IMHabdnsxMzDjVXoBs7gjfO

Download the file from my drive (couldn't upload it directly). Install Viper and let it install the driver and reboot. When it stuck on fastboot mode, reboot to recovery and paste this file to data/adb/modules/Viper4Android. It should overwrite the original system file and the system should reboot well.

Successfull for me on Havoc 3.0 :) Worth to be on Telegram ;)
[Android Apps and Games] DiamondJohn:
I have a "test" phone runhnng an alpha build (my own, of Q and when I installed Viper, it had the same issue (again to be clear, its a very alpha build)

To get out (ie uninstall Viper) I went into TWRP and deleted the folder (something like) /data/adb/magisk/modules/viperfx (something like that, not exactly, its easy to find, and I am just going off memory)

My next attempt will be to selectively delete parts of the Magisk module to find which artifact is causing the reboot to download mode. And, maybe it could work with the offending part removed while not causing the reboot to download mode. Let me know if you try the same.

Compression settings for speech

I am running V4A 2.7.1.0 on a Oneplus 3t with LineageOS. I use V4A in a less conventional way.

I regularly listen to podcasts on the phone speaker so this is a speech only (no music) application. A lot of podcasts can't seem to balance the various voices so I am continually messing with the volume. Male voices tend to be quieter anyhow so boosting the low end helped a bit. I've been playing with the FET compressor and made the situation a bit better but still not great. The trouble is, I'm going at this somewhat blind. I've spent hours reading documentation over the past several days, and while I now have a basic understanding of the terminology (attack, inflection, etc..) I am unsure of it's real effect on the output. Most audio compression for speech guides are geared for recording, and I'm not sure how that translates to playback. Unfortunately, all the guides and "recipes" I could find are for great sounding music in headphones. (that's important, but not what I am looking for in this case)

If anyone can give me a starting point, that would be super awesome. I can fine tune it, once pointed in the right direction.

I started with a WAG, which kind of worked, but some voices were pretty muddy so then just tried fiddling to make it sound clearer.

What I have now:

Master limiter

Output gain: -6db

Threshold limit: -6db

Playback gain

Strength: 2

Max gain: 2x

Output thresh: -6db

FET compressor

Operating thresh: -50db

Compression ratio: 20:1

Inflection: 50db

Inflection pt gain: 0.8x

Automatic gain: yes

Automatic attack: yes

Max attack:: 40ms

Automatic release: yes

Max release: 90ms

Crest: 6db

Adapt: 1200

Clipping prevent: yes

Thanks for any insights.
[Android Apps and Games] Zilla0617:
I agree wholeheartedly that is better than the previous version. Until u suggested I never thought the jabra+ app could make much difference so when I changed it to bass boost profile...I smiled. Thanks
[Android Apps and Games] Joe199799:
Yea no problem, wish I could make presets for other headphones but sadly I only have the X4's and Jabra Elite's. Never thought anybody would take interest in my presets so I'm glad you enjoy it.

---------- Post added at 02:42 AM ---------- Previous post was at 02:39 AM ----------

Look around in convolver I posted a drive file with over 300 of them. a decent amount can help with voice clarity and depth. I actually have a preset for a radio show I listen to I could post it but it's really bare bones and very specific to my headphones, but if you want to give it a try let me know.
[Android Apps and Games] Kenyoni:
Convolver (...lots more reading...) Gosh, that's pretty cool. :)

I got your convolver samples, much sweetness. Thanks!

Sure, if you post your radio show preset, it will at least give me a starting point. Between that and the IRS files, I should be able to figure something out that will work.

If you have the audio compatibility module installed with viper I think you need the audio modification library module installed as well to make them work properly all the time otherwise it'll be spotty

Hey Guys,

is it possible to remove the icon in the statusbar without killing the whole process/service.

Until now i used the legacy viper4android magisk module, and there wasnt any notification.

Now im using MIUI 11 with Android 10 and the latest version of v4a.

Hi all,

Weird problem here: when I'm connected to bluetooth, V4A processes key press sounds, keyboard clicks etc (I don't actually want this to happen but it does anyway), but changes to Processing:no when I play music. This either happens immediately (with Poweramp), or takes 2-10 seconds (with Mixplorer's built-in audio player) i.e. after this the music continues to play (no pauses/audio dropouts) but without the audio effects applied.

But when I install "ViPER4Android FX 2.7.1.0.apk", install driver & auto reboot, it can't boot up & auto boot into fastboot mode!

Sometimes can be boot up, but the second or third time, a few hours later or overnight, device also can't boot up after off or reboot, it also boot into fastboot mode!

I had reflash stock rom & reinstall all programs many many times, but after OOS 9.0.8, also can't boot up after install "ViPER4Android FX 2.7.1.0.apk" !

Please, who can tell me how to solve this problem!
