[Nexus5]Lollipop UPDATED OP August 7th!!! [Zip Package] Viper4android

Attached are the latest updated zips.
FAQ:
How do I install Viper???
Go into recovery and flash the zip. It will take care of most of the steps for you. Upon your first launch of the app you will be prompted to install drivers of your choosing then be prompted for a reboot. If coming from a previous version of Viper or you have any other sound mods I fully recommend uninstalling them. Then go into recovery and flash your ROM and the zip in one session.
Well what drivers do I use???
I recommend Super Audio quality. It uses a higher sampling rate which can be thought of as like a megapixel on a camera. More sample information equals cleaner signal but your files must be equal to or better than the driver sampling rate. I find the highs to be much cleaner and have less distortion with Super Audio. While the prompt warns about extra battery usage, testing with Better Battery Stats for me has shown the effect on battery life to be minimal. You will get higher drain using the Convolver then by choosing a higher quality driver.
Well what is Convolver and how do I use it???
Convolver will play a real time sample of an effect or eq as the sound is being processed. You can get really awesome effects from some of the irs samples but they come at a high price of battery usage. Using this setting doubled battery life usage for me on even conservative kernel governors. To enable you must go to the menu and enable Moderate or Expert UI, then press the button to enable Convolver and press Impulse Response, this will create a ViPER4Android folder on your SD card and within that you will have a folder named Kernel. This is where you will put your Irs Samples you download. You can find links to Irs packs here: http://forum.xda-developers.com/showthread.php?t=2216193 PS......I've found that not all samples in all the packs work correctly and some will give no sound change.
HAAAAALP! This stoopit mod is killing my battery!!!
No it isn't. Unless you're using Convolver after being warned about it's effect on battery you should see little to no difference in daily use of getting notifications, texts, etc. I get about 6% an hour battery usage during music playback while streaming over bluetooth. If you're using a wired headset it should be less than that. I have never not even once seen Viper pop up on my stock battery stats and have only seen it as <1% on GSam after a full charge. Compatibility mode can be used as a last resort and final option if you're determined to call me a liar. Steps to enable it are outlined below.
This hack is ballz...I know wantz no mo???
To completely remove the changes done by my install zips you will need to do a manual wipe of system/davlik/cache to get rid of everything and then reflash ROM/Gapps/Mods. Reflashing your ROM without a manual wipe will not remove anything do to the addon.d scripts added so the zip will survive dirty flashes.
Why put the app in priv-app???
This will help to insure that Viper doesn't get killed by Android OOM to keep the sweet sound pumping into your ears!!!
My Viper isn't working!!!
Did you install by flashing the zip??? Is your apk in priv-app??? Do you have any other conflicting sound mods or eq's??? Is Viper enabled and you have installed the drivers and done a reboot??? Have you put SELinux into permissive mode???
Some people have luck adding or changing these lines in their build.prop:
##Viper4android
lpa.decode=false
tunnel.decode=false
lpa.use-stagefright=false
lpa.releaselock=false
Also some music players work better by switching to Compatibility Mode. To do that go to menu, click FX Compatible Mode, then click Compatible. Doing this should cause Viper to only modify media players instead of changing sound system wide. Some users say this helps with battery usage as Viper will only process sound when you want it to.
Still stuck? There is tons of helpful information in this thread that you can find by helping yourself click that "Search this thread" function towards the top right of your screen. Still stuck after that....ask away!
Wanted to say thanks to @rootSU and @FlyinGrub for lending a helping hand, @FuMMoD for posting updates to the Viper apk and libs, @davwman for getting this thread started, @Hid3rs for the Material Design framework, @chdloc for the awesome Stereo mix, @Spasticdroid for the audio_policy editing script, @Alex240188 for the material design Viper 2.3.4.0 apk, @//.dax for the sweet new icon. And of course the awesome Viper team for creating Viper. I refuse to run my phone without it!
Here is a link to the official thread for more information: http://forum.xda-developers.com/showthread.php?t=2191223
!!!!!!LOLLIPOP USERS!!!!!!!! You NO LONGER need a full permissive kernel to get Viper working as long as you use SuperSU. To test your kernel open Google Play Music and play a track. If you get a "couldn't play stream requested message" you need to download this app http://forum.xda-developers.com/showthread.php?t=2524485] and set it to PERMISSIVE mode, find yourself a full permisssive kernel, or switch to SuperSU. Enjoy!!!!
P.S.:
LolliViPER.zip will install Viper to priv-app and remove Audio FX, DSP Manager, and Music FX. It will also edit the audio_policy.conf for added app compatibility and add a script to allow Viper to work with SELinux enforcing with SuperSU. ***BONUS for ROMs with addon.d support-the zip will place a script into addon.d that will automatically backup and restore everything changed by the zip on dirty flashes eliminating the need to flash every update so long as you do not do a manual system wipe.***
LolliViPERsurROUND.zip will install Viper to priv-app and remove Audio FX, DSP Manager, and Music FX, and change the mixer path to enable the earpiece as a second speaker for stereo sound. It will also edit the audio_policy.conf for added app compatibility and add a script to allow Viper to work with SELinux enforcing with SuperSU. ***BONUS for ROMs with addon.d support-the zip will place a script into addon.d that will automatically backup and restore everything changed by the zip on dirty flashes eliminating the need to flash every update so long as you do not do a manual system wipe.*** !!!!!THIS MAY CAUSE BOOTLOOPS ON DEVICES OTHER THAN THE NEXUS 5!!!!!
5.1.x stock ROM users may need to remove system apps for the install to work. Google filled the system partition to the brim with little to no room left for installation.
The apk in all these zips use the Material Design Framework and may not install on devices lower than 5.0.

Im using it since the start so i cant really comment on How it was before but the sound quality is awesome on my n5. Dunno but i guess The bass is a bit low so i Bad to raise it More than other EQs I've used.. I heard the KitKat DSP is pretty nice as well but as I said I can't comment on that?

V4A works well on N5 BUT:
- I sometimes have interferences when listening to my podcast audio files. I need to make some tests to know if this is due to V4A or an audio mod.
- there's no more IRS options atm and this is a shame!
- I'm going to flash OmniROM (again) and I'll only use DSP app for a few days and see what happens.

I won't run a phone without it!!!

Been running Convolver with IRS samples since Nov 9th. I did notice that some were taken down but there are still some out there.

which mode are you guys using? Battery saving, high q or super quality? Also, it says, that super quality may increase battery drain.. Dont you guys know how much it takes from battery? Thanks

I'm using it on high quality. I DO notice a difference. The sound was a lot flatter before V4A. It's much more robust with it.

Super quality here. Battery usage during music is fantastic for me even streaming over bluetooth.

Super quality here. Purity Rom + Franco + PA Mini Gapps + Viper = rockin'
Not real noticeable on n5 speakers, but with good headphones it's night and day.... and my Klipsch s4's are not the best, but good enough for my listening. Some good profiles here.

What version do I download?

FX version v2.3.1.3 (Android 2.3~4.4): Mediafire

I went with Battery Saver. I'm not an audiophile and all I mainly listen to are podcasts. It *does* work, you can definitely here changes when you activate features or change sliders. Using the Convolver with Urei 1178 Impluse.irs, but tried Beats and WaveMaxx .irs as well. I was a EIZO user, but when they got rid of user configurable EQ, I baled.

If you are using equalizers from within music players like Poweramp, does viper4android improve sound quality in some other way apart from offering equalizers?

You can run it in compatibility mode and it will enhance your built in eq's.
I love the .irs files and what they do to the sound. I love tube amps and I play with the different .irs tube files and you can really notice a difference. I made sure to save all the .irs files I found and I'm glad I did.

Just installed v4a and started playing with it. Any recommendation about .irs files or are they strictly related to headphones?

The convolver works with any of the modes as long as its turned on. Go to the "official" v4a site --> http://vipersaudio.com/blog/ and download the couple of files they have and try them out. I think the v4a developer has basically stopped all links to any .irs files and is "centralizing" them. But you know the deal, whats on the web stays on the web, so seek and ye shall find.

Has anyone gotten it to run with Rocket Player? It isn't working at all with it over headphone or speaker. Driver status processing=NO. I've tried all the workarounds and none of them have helped.

Am I just high or what? I can't find a flippin download link?

IRS options are still there, you just have to set it to Expert instead of Beginner

Damn! I didn't know there was different modes into the app!!! You made my day
FYI the interferences I had were not due to V4A. I changed my rom, kernel and didn't apply the audio mod and everything works fine now.

Microphone sensitivity to strong at Video recording

Hello,
Is there a way to reduce the sensitivity of the microphone when recording a video?
Every concert or Music is distorred.
Withe the Galaxy S3 it was possible by using the Boeffla Kernel. But it doesn't exists for the I9506.
Thanks

which rom are you using?
for CM-Roms i confirm that, its awful.
you have to modify mixer_paths.xml but I already tried this and still getting bad results. this is the reason i am thinking of returning to stock rom soon.
edit: maybe i give fauxsound a try..

In Dehaws kernel is a possibility to reduse sound levels. Inc.camera microphone, with faux sound or kernel audiitor. But then u need to be in DeHawk rom. Or compatible rom.

I'm on stock rom 5.01. Debloated and rooted with Xposed Framework!

The phone is also capable of AGC (auto gain control) but it probably must be supported by the app. RecForge-II (audiorecorder) does support it for example. Maybe try some other video recorders.

I adjusted the values in the mixer_paths.xml file.
Under the "Recording Scenario" I changed all the values from 84 to 65.
This did help.
Default values: https://www.youtube.com/watch?v=IpxeCCrD7eU
"Fixed" values: https://www.youtube.com/watch?v=n9QNj6ecpkU

Note that the second video is still slightly distorted soundwise, but it's exactly as I hear it in my car... VERY loud, to the point of uncomfortable

i can't take a look to the video because of the GEMA in GErmany.
So i have edited the xml file.
Will give it a try at the next rehearsal or concert
THX in advance

hehe i also wanted to look into the vids, but as located in germany, there are licensing troubles too.

libaudcal.so issue

This is a file from a viperaudio sound mod, and I'm having issues with calls (people on the other line hear an echo).
I already asked in the thread, and contacted the dev, but I didn't get any answer.
There's a way to solve this issue by deleting the file, but it harms the audio quality.
That's why I'm wondering if there is any way to edit this file?
Check second post

Actually, I've made some new discoveries about this issue.
The libaudcal.so file is present on our devices in vendor/lib.
If this file is deleted, then it has the same effect as copying it from another device (installing the one from the old viper sound mod).
That means - incredible huge bass on speakers, but issue in calls, the other person on the call hears an echo, and the in call volume is stuck at a constant low value.
Now, what's interesting is that this issue is NOT present when making calls via viber, facebook messenger etc. apps.
I've tried downloading different dialers, and using different rom versions, but no difference.
It seems to me that there are filters included in this file to purposely cutoff low frequencies, and that calls are broken when the original file isn't used.

I hate to give up, so please if anyone has ideas on how this could be resolved, I'd appreciate it.

Maybe you know how to increase output sound to audiotrack in android 7.1.2 without that file ?

G900F mixer_paths.xml RECORDINGS (Whatsapp) are far to low, as well as the speakers?!

Dear folks,
I used to search this and other forums for an easy solution to increase the volume level of my Galaxy S5 (G900F) in both directions, to mic something and for listening. I do not care of speakers (to destroy them) or my ears (they are already in bad status since the DISCO-Beats in early 90ties), smile, but I hate to anoy my friends with to low volume messages (even when I am at home with no background sounds). In the car it is even worse. My phone is rooted. Android 8.1.0 Extend Version AospExtended-5.4-unofficial, 2018-April-05, G900FXXU1CPC9, with Kernel 3.4.113-lineageos-g808bf80, Build-Number OPM2.171019.029, Moderate
I have downloaded and testet micgain26higher.zip, micgain26normal.zip, Mic_Gain_Mod_v11.9.zip, and s5_Volume_Boost_Version_vX...zip
None of it works.
I even extracted / copied the three files from container to /etc, with no positive result.
I tried to increase the numbers within mixer_paths.xml by hand, no improvements.
Please give me a solution (preferable a ready made mixer_paths.xml to copy/paste).
Thanks.

I think there is no solution - mine is loud for me, but my mic level is poor. I expect nobody is good enough to help you here.

Copy the mixer_paths.xml that i have attached to "/vendor/etc" and change permissions to "rw- r- r-". (ps : i think it is not necessary to change permissions anymore but just in case you can try)
For me it works on recording audio

The guy in this thread.....
http://forum.xda-developers.com/showthread.php?t=3202087
Knows a *lot* about adjusting the xml file to make adjustments to various volume level parameters. He was able to give me a lot of help when I needed it. Why not ask in that thread.

Sound profiles for viper4android?

Hi All,
Is there a place to find the sound profiles for viper4android for G5 plus? I am looking for a sound profile which is very close to the stock ROM in terms of the sound quality and clarity.

You won't get sound profiles exactly but can download IRs. Just google viper4a IRs . Download any one of your choice. And then paste that in the kernel folder in the viper folder located in internal storage. Load that and you can make tweaks on top of that. There are lots of IRs like dts dolby beats.

I guess I'm at a loss why you need to use an app to get the sound back to stock. If a rom is modifying the sound, I would hope you could remove the mod or app they are using to affect the sound. Post in the applicable ROM's thread for assistance in doing that.
Otherwise I think you probably have a unrealistic memory of what the stock room sounded like.

This is very true, my friend. Even though the PIE roms say, they are using the Oreo firmware, I don't understand why does the sound in PIE roms sound so much different than on stock Oreo?
