Presets/profiles

I see a few posts of people looking for presets/profiles for specific music genres and you really shouldn't use those.

Viper should be configured according to the listening device you're using (headphones/headset, speaker, etc) and not by music genre.

If you configure it according to how you like your sound, it should be good for any music genre.

If you don't know how to configure Viper, you should at least know how you like to listen to music, like how much bass, how clear you want the high frequencies, etc...

Then you just tinker with the options until you get your sound.

Here's an example of a pretty generic setup that sounds good (at least for me) for most medium to high quality headphones/speakers (a classic V shaped equalization lol):

- Master limiter: ON (of course)

- FIR equalizer: ON

- Preset: Rock

- Dynamic system: ON

- Device type: Extreme headphone (v2) (I feel this helps with clarity of sound a bit, may be placebo or I may not be using it correctly)

- ViPER bass: ON

- Bass mode: Natural bass

- Bass frequency: 80Hz

- Bass gain: 14dB (I like bass, in any music genre)

- ViPER clarity: ON

- Clarity mode: Natural

- Clarity gain: 10dB or 12dB (depends on the headphones I'm using, I want clarity but don't want the high frequencies to pierce my eardrums)

- Auditory system protection: ON

- Binaural level: 2 (I use this with any headphones because it really helps protect your hearing, except of course if you crank the volume waaaaayyy up, but that's another story)

Any setting/sub-setting I didn't mention it's because I didn't use/change it.

I have 2 pairs of headphones with which I also use the Convolver setting and a Impulse Response Sample file (.irs which is basically a .wav file but Viper uses .irs) to correct some frequencies.

What's this you ask? Well imagine you buy a pair of headphones, but they have so much bass that it drowns the mid and high frequencies. An Impulse Response Sample file contains a waveform that is used to correct that and balance all frequencies so you get a clearer sound (someone please correct me if this is not the correct explanation and I can't get more technical than this).

Here's a thread with a lot of IRS files for a lot of different headphone brands/models:

https://xdaforums.com/showthread.php?t=2372750

IRS files should be put in the folder /ViPER4Android/Kernel/ in your internal storage.

The only thing which seems to be important but I never learned how to configure is the Compressor setting, will have to delve into that when I have the time.

Hope this helped someone. :)

Love the app, but hate the struggle with the driver - it seams to be a never-ending-story.....

I also wonder why you release an app with primary just a slightly different UI, and don't focus on the most complained issue with this app?

It's like releasing a car without wheels, and then offer a new color as a solution.

There was a period when it worked for me - when I used the 2.6.0.5-apk version - but silly me wanted to try out your new 2.7... that was a mistake. I have tried every suggestion, reinstalled, installed all extra Magisk modules, changed installation order, etc but the driver don't kick in. Or, just on occasion it does actually doew, but a reboot will destroy that joy again.

The 2.6.0.5 did always worked for me, but version 2.7 is useless. And the irony is that when I now tried to reinstall 2.6.0.5 again, even this version is failing for me. Honestly - have not change anything else on my phone.... (OnePlus 6T, stock version)
[Android Apps and Games] libracez:
i don't have problem with notification and driver status is normal just when you trying to manage any settings during listening music - nothing changes
[Android Apps and Games] sjamie:
When you had 2.7 installed, did you actually turn it on (Master Limiter)? Many people miss that step.

As you can see from the overwhelmingly positive posts in this thread concerning 2.7, most people (including myself) really appreciate the dev's work to create this version. It certainly works much better for me than any previous Viper version. I hope you find something that brings you the same level of joy.
[Android Apps and Games] kpirnie:
if you can produce a log, maybe, just maybe a developer could help YOU diagnose YOUR issues...
[Android Apps and Games] rwSN1PER:
2.7 is working great on my OnePlus 5T running MSM Xtended!
[Android Apps and Games] F5:ed:
First, I raise a very common problem with Viper. A common problem since years, but the developers seems more interested of release a "fresh design", than trying to fix the BIG issue with his app. That is not a problem solving move.

Second, some random guy advise me to check if I have turned on the app. If he had read my text, he should have realised that I have tested more or less everything so his "advise" was pretty lame and close to offending. That do not helping at all.
[Android Apps and Games] Joe199799:
The whole app was rewritten in kotlin a ton of bugs present in 2.6 were fixed due to this and the updated UI makes things more consistent instead of there being options for basically the same things. And the answer you got was because a lot of people didn't realize master limiter is now the on switch.

if you have any problems feel free to PM me so we don't clog the thread with this nonsense
[Android Apps and Games] kpirnie:
heres the problem mate....

1st and foremost you provide 0 proof of your issue, nor do you make any attempt at diagnosis, yet you demand the developed (who did this for free by the way) fix it.

2nd you come on talking smack like everyone here owes you for even being here.
[Android Apps and Games] sjamie:
It's all good. I really enjoy helping others when I can and I never let the trolls get in the way of that. If they knew how I move in real life, they would think twice about what they choose to say to me. ;) :cool:

New presets

Can anyone share good new preset..?ty
[Android Apps and Games] rippledrums:
Can you tell me if the issue with this new version not being detected by the system as an equalizer is being looked into?

To be honest that's the only thing that's "nagging" me a bit but of course it's not critical, just lost a shortcut from my music player. :p
[Android Apps and Games] robotzki:
If you use it in car, it would be through Bluetooth or aux (same as headphones)?
[Android Apps and Games] Redline:
I suggest everyone can it before things escalate further.

Keep the thread on topic, there's no need for ANY of the things I've read on the last few pages of the thread alone.

If you have an issue with something someone is saying, or think it breaks an XDA Rule, use the report button so we can have a look at it.

There's no need to needlessly quote the offending text, paraphrase forum rules, or retaliate in any way. You only create more clutter that takes us longer to clean up later on.

Consider this a thread-wide warning

.

There are multiple rules that have been broken just on the last few pages of this thread alone, most notably:

Further posts that break these or any of the other site-wide XDA rules are welcomed to be

reported

to be brought to the attention of us moderators, so we can deal with it properly.

Thread cleaned.

I apologise for what I commented but I was sticking up for the devs here and the dude helping people out in this thread
[Android Apps and Games] Redline:
It wasn't any one person in particular. There were multiple people acting out, and I felt everyone needed a general reminder to keep things civil, on-topic and productive.

Apologies if you thought you (or anyone else for that matter) were being singled out, it's hard to gauge the tone of a text-based message sometimes :)

I remember reading that Viper no longer needs the Notification helper removal module because it's built into Viper now. Is that true or do you still need the additional module? I'm experiencing ducking/cutoffs with notifications but I'm trying to flash as little modules as I can...
[Android Apps and Games] madprofessorus:
I have two suggestions for future upgrade,had to remove the new app and switch to the 2,5 version,first I had a problem,maybe because i removed some irs files,and it wasnt working,and couldnt shut it down,so an exit option like the old one has would be great,also a default black theme,cant switch my phone to black mode,is not supported on marshmallow,and i'm sure most people like black themes in general...not tiring to the eye and power saving
[Android Apps and Games] DiamondJohn:
Have you tried setting the Nice value to see if it solves your issue?
[Android Apps and Games] agplugged:
I don't think I know what the Nice value is, I don't see it in audio_effects.conf or audio_effects.xml...
[Android Apps and Games] slgooding:
I installed the audio compatibility magisk module and that fixed my issues with notifications killing the driver/processing. I'm running PIE. Maybe give that a try?
[Android Apps and Games] libracez:
It was working for me, p2xl on havoc.. Then I delete a module and tried 2.7 and it wasn't now I am trying to give a shoot on magisk latest and 2.7 few times, with deleting, reboot, install, reboot.

But not.. Why this could happens?

[NOT WORK]

Android Pie 9.0

Syberia OS Mi 5

Rooted

Magik Installed

Downloaded from XDA Lab

Installed Completely

Viper version by XDA version not original :

2.7.0.0 [NOT WORK]

Not with Spotify and other

2.6.0.5 [WORKED]

Get warning about Poweramp Direct Control and Disabled and WORKED

Work with Spotify and other

Checked everything nad rebooted several times

1 - UI Always Light even when we set android Pie set to Dark

2 - Not get warning about Poweramp even I install poweramp and enable Direct control but in previous version UI can be dark and we get warning about Poweramp too

Better to check the new version

Thanks in advance

NOTE :

Also check the new driver comes with 2.7.0.0 that work with viper 2.6.0.5 [Viper new delete install previous version and 2.6.0.5 don't ask for driver but work with driver come with 2.7.0.0 which installed]

This is strange but it worked
[Android Apps and Games] DiamondJohn:
Its a general android thing, not audio specific. It basically sets the thread/process priority. ie if you set the nice to have a higher priority (a lower value), it will be less likely to be interrupted by other processes; ie less chance of stuttering, maybe. Do a web search to understand it further. Its a feature carried over from Linux/Unix

There is MANY pages instructing on how to do it on the internet, but it is a little convoluted. I have built a tool which simplifies it: https://xdaforums.com/android/apps-games/app-temefi-comprehensive-documentation-t3806260

You can find it under: "Application Info/Manage>Nice>Nice An App to Highest [-20]>com.pittvanderwitt.viperfx"

Then see if it makes a difference. You can also increase its OOM value as well.

NB: Both will be reset/undone on a reboot or app exit.
[Android Apps and Games] F5:ed:
Great to see that you have identified the bug(s) in Viper 2.7 regarding my device OP6T - like I tried to explain for some fan-club members here (without success....) - and that Dev trying to solve it :highfive:
[Android Apps and Games] agplugged:
I appreciate the help on that one. Thanks for enlightening me on the matter. I'll try it but right now just installing the Helper removal module seems to solve all of my trouble atm. If that falls in some way I'll give it a shot and report back to you.

I'm a little late to the party on this version of viper so I'm not sure if all this is known or unknown but I'm using a stock deodexed Samsung rom 6.0.1 and haven't had any issues with processing even with Spotify. I'm not using any compatibility patches or anything different other than the drivers that I'm using which is from the 2.5.04 version. (edit- Reading comprehension is not my forte)

Here's the way I installed this version. Most of that's probably unnecessary but it's just the way I've always installed viper in the past.

My apologies if you're only speaking of newer Android versions. Just thought it was worth mentioning just in case.

Thanks [MENTION=8722814]Dr.07[/MENTION]

Viper is great app

I would like to contribute

Is there any GitHub or other source control version ?

Can I join for contribution ?

By The Way, for our friends ask about SElinux :

Viper work with Enforcing no need for change

Also

version 2.6.0.5 work on all platform [I TEST IT WITH MY CUSTOMERS PHONE's]

As [MENTION=8722814]Dr.07[/MENTION] said they are working on new version that many bugs are fixed already

I love this app

Great equalizer and audio customization

Thanks for paying your time on this

Had Any One tried Viper4Android 2.7.x.x(I'm using APK) on Pixel Exp.? If yes, may be you can help. Things are working fine sometimes, few concerns are :

[I installed Viper4Android from XDA labs and gave root permissions then things didn't work. Installed Audio Compatibility Patch as read on the offical thread of this App then also things didn't worked out. Installed Audio Modification Library then starts working a little bit. Initially it is not processing but after sometime it does starts processing. ]

1. Systems sounds were broken( there is this jizzz in every notification/alram/timer) sound.

2. Playing songs videos from phone/streaming media have fine sound nothing broke, I can contro that from Viper control menu.

3. If Processing=yes (my driver are installed everything else is YES and supported), Bluetooth devices won't get any sound instead phone speakers are taking the profile setup for Bluetooth and playback are on phone speakers (sometimes).

4. Didn't test earphones yet.

<Img1 attached has currently processing=NO as I was not playing any media at that time. IMG 2 It will turn to Processing= YES> All driver are installed. I used Old method (remove) while installing Audio compatibility patch (new one (patch) method I think it didn't worked for me).

If any one even point to a helpful post regarding this issue, that would be helpful too.

Try this..

Open v4a, tap on the menu.

Trying to get this working on an S7 with Stock Firmware rooted via CF Chainfire. SM-G930W8 android 8.00

On the latest version of the App it detects there's no driver and attempts an install. But then it just keeps crashing out with "V4a keeps stopping". The previous version of the app (2.6.0.5) says it's able to install the driver but then reports that it's abnormal.

Can I try anything to get this working? Would really like to be able to use my awesome HRIR from HeSuVi on Android

[Android Apps and Games] KUSOsan:
So I installed the 2.7 on my V20 running Alpha Oreo with Magisk 18 and I installed audio modification module from magisk and everything ran perfect for about 5 days and then all of a sudden it just stopped working and nothing I tried would fix it except for a reboot. Then after that Viper would work until about halfway through the day or so and same exact thing. I made sure to exclude Viper from power savings.

I eventually uninstalled the audio modification module and reinstalled just viper by itself and same exact thing every day. Right now I'm trying Viper + Audio compatibility module + Audio Modification module and so far it's lasted through a day so I'm hoping because this version of viper has finally been working flawlessly for Bluetooth on my V20

So the that combo didn't work either. I'm currently using just viper 2.7 and just the audio compatibility module and it's been over a day and still good so here's hoping.
