Sorry, forgot to mention, I am using Stock Mod ROM from here http://xdaforums.com/showthread.php?t=2505682.

No Xposed, but I am using custom kernel from here http://xdaforums.com/showthread.php?t=2472318.

Using Stock Music from LG. Compatible mode didn't work either.

But when I was using his ROM from here : http://xdaforums.com/showthread.php?t=2493209 + same custom kernel from above, I remembered that the sound (using Stock Music LG) did have a different.
[G2 General] alex72:
[MENTION=5340359]htcm7[/MENTION] I'm guessing that you tried different music players and none of them worked with V4A. In that case, I suggest to try previous version of V4A (v2.3.1.3). Proper uninstall procedure is that you uninstall driver thru V4A menu than uninstall app itself. Reboot.

http://www.mediafire.com/?t5q9rw81xb1371o

Before you go to previous version you should check that your build.prop edits stick. Do you have Busybox? If you don't, most likely, edits didn't stick. Check post #218 for tips and instructions.

BTW, the easiest method to notice change of sound is by switching irs files. In order to see Convolver and Impulse Response you need to go to UI Setting and use Expert option.
[G2 General] jujjk:
I'm stuck in a bootloop after installing ViPER4Android. I'm also on the StockMOD rom. I've had to re-flash it twice now.
[G2 General] alex72:
So what was the cause? Did you install it as user or system app? Did you mess up editing build.prop files? This is first time I ever heard that you can get into bootloop after just installing V4A.
[G2 General] htcm7:
Have tried V4A (v2.3.1.3) and still not working.

I have Busybox from Trickster and already check build.prop edits, they are stick.

When I ticked Impulse Response, there is a warning message, something like V4A\kernel folder is empty. Could it be this is the reason why it doesn't works?
[G2 General] jeff5347:
Did u DL the IRS file zip from the first page? If you go in your file system, after installing v4a you should have that folder and inside have another folder named kernel. DL the IRS zip file and extract its contents. Copy all the contents ( something like 100 files) and drop them in the kernel folder. Go back to the app and click impulse response and now they should all b inside to choose from. Hope this helps
[G2 General] JRJ442:
Lol. That happened to me once on my S3. I went nuts and added all those lines to the build prop. I'd try it without adding those if you did.
[G2 General] htcm7:
I have downloaded a few of IRS file and extract to that folder. If I am not mistaken, this IRS file is for playing via headphone, while I play via speaker phone.

No effect when playing via speaker phone.
[G2 General] alex72:
In order to see and use Convolver and Impulse Response files in Phone Speaker go to Menu/UI Setting/and choose Expert.

G2 has one tiny speaker and it's hard to notice sound changes but if you use something like Studer HalfInch +6dB you'll notice for sure.
[G2 General] htcm7:
Yes, I have set ui to expert mode, still no change.

To make sure, I reflash again my ROM to ray globe, and audio does have better quality.

So, I think, I will stick for a while in ray globe, and postpone this mod.

Will be back to Viper4A when custom ROM based d802e available.
[G2 General] alex72:
Reyglobe Rom has ViPER4Android built-in so no suprises there.
[G2 General] ShyamSasi:
Is it worth rooting the device for this Mod? Because in most cases I don't find the need to root the device. Is there much difference after applying this mod?
[G2 General] JRJ442:
Definitely. I use Viper on all my devices and your listening experience will never be the same, especially with some good headphones.
[G2 General] ShyamSasi:
That's good. As if now I use Sony XBA H1 with FiiO E6 Headphone Amp.
[G2 General] ShyamSasi:
Rooted and Installed :)
[G2 General] chasist:
It seems that if u disable play music viper4android will not work

Edit: it doesnt work on lg stock music player but works great on play music
[G2 General] alex72:
It depends on ROM you're using. I'm on LG stock based CleanROM and I needed to edit build.prop files to get LG stock music player working with V4A.
[G2 General] snake2332:
Driver install failed, please confirm your phone has been rooted and su binary.......

I really want this to work with the CM11-based "unofficial" rom (this one: http://xdaforums.com/showthread.php?t=2559920). However, it fails to install the driver, stating: Driver install failed, please confirm your phone has been rooted and su binary installed. I see the pop-up message saying "SuperUser granted to ViPIER4AndroidFX" right before the error message, so SU appears to be working fine with Viper. I have tried versions 2.3.1.5 and 2.3.1.3. The 2.3.1.3 APK won't even install. It just says "X App not installed." when attempting to install it.

Oh wait, I just tried making it a system app and running the install again. Now it says the driver installed, woohoo! However, after a reboot, my phone is frozen. Hard-booted it and now it's working, sweet.
[G2 General] alex72:
[MENTION=3386918]snake2332[/MENTION] So which version of V4A works with CM11 as a system app?

Edit ;

It looks like that CM11 Rom you linked in your post has ViPER built-in so maybe that's the reason why you had so much trouble over installation.
[G2 General] chasist:
Yes u right. I edit the build.prop and now its flawless
[G2 General] ShyamSasi:
I have downloaded the from the link provided in the OP. Edited the Build.prop and installed BusyBox. V4A works fine for some time then it stops. The information screen says No for everything. Then if I remove the driver and reinstall the app then install the drivers it works fine for some time, again it stops. I'm on stock ROM.
[G2 General] alex72:
You gotta edit build.prop before you install V4A. Reinstall driver again and if you have same issue try it as a system app. I used Titanium Backup for that task.
[G2 General] ShyamSasi:
Yes I edited before the installation. I'll try it as System app.
[G2 General] alex72:
Are you using latest SuperSU? If you do, maybe you should flash latest SuperSU zip thru custom recovery as a good measure.

http://download.chainfire.eu/372/SuperSU/UPDATE-SuperSU-v1.86.zip

Hopefully you won't have any problems with ViPER as a system app.
[G2 General] NomadCF:
While I love this app, I'm seeing some massive battery drain from it. I've got it narrowed down to viper as, after I disable it and reboot the drain is gone.

Anyone else seeing this?
[G2 General] ShyamSasi:
I installed it from PlayStore. I''ll try this.
[G2 General] alex72:
I don't but some users, like yourself, do. They'll fix it in next version but for now either install power saver driver or use previous version of V4A (v2.3.1.3)
[G2 General] NomadCF:
Thanks trying it now (the older version) .

Hi Guys,

Does anyone have the Impulse Response files for the Xperia Z1? I really want them as I loved the sound from the Z1!!
[G2 General] lequocvan:
Can it work on f320l?
[G2 General] alex72:
Try it and let us know. BTW, nobody reported that it doesn't work so it's a safe bet that it works like it should.
[G2 General] alex72:
Maybe this post is what are you looking for...

http://xdaforums.com/showthread.php?p=48961087

It has Sony Xperia Sound Enhancetment irs. BTW, it's not free. It costs $2 for single set and there are combo "deals" as well.
[G2 General] Sean473:
Well OP, your original post where you had a collection of Impulse Response files has those for Xperia S? Where did you get those? Maybe the same person is still developing for Z1 maybe... I've seen the link but I'm not interested in paying as it looks dodgy to me in the sense it seems very general...
[G2 General] alex72:
Same guy have all those in lower quality for free, similar to my attached zip irs files... Maybe you should try free ones...

[G2 General] lequocvan:
not working on korean version
[G2 General] alex72:
Do you have problems with driver install or there is no effects in your music player? If it's later, change music player or do build.prop edits like described in post #218.
[G2 General] Sean473:
Yeah I've already seen those... Is there any way for me to make the files? I can get a stcok ROM to pull any files from it...
[G2 General] alex72:
Yes but it's a time consuming process and involves expensive equipment (quality soundboard card) and have nothing to do with stock ROM files.
[G2 General] Sean473:
Ok I guess I'll just have to wait for someone to make them.. I can do with what I have for now...
[G2 General] alex72:
Did you try BSDgeek_Jake irs files? Those are best HD quality irs for free IMHO.

[G2 General] Sean473:
I'll give it a go.... Thanks again.. I've tried the Xperia S ones and they're pretty good.... Hopefully someone makes it for the Z1 eventually.. I had a look at the Zhuhang guys Impulse Response thing for Sony Xperia Devices... He somehow combined the Xperia S files with the Z1's audio libraries... Would be interesting if I could do the same...

Hi all,

Can I use this together with this http://xdaforums.com/showthread.php?t=2542398 ?

It works with power amp. There are specifics in this thread about making sure to use external effects while in power amp but I don't remember all the details off hand....
[G2 General] alex72:
I can confirm that it works. I just tried it for you. You gotta go in Advanced tweaks and turn off DVC and enable MusicFX. Holding MusicFX in Vol/Tone screen brings V4A FX setting screen. Go to Menu and choose FX Compatible mode. You won't be able to see driver status but you'll feel the difference. Enjoy!
[G2 General] alex72:
You gotta be more specific in order for someone to help you. Try different music player. I suggest GoneMAD and Shuttle+. If you prefer LG stock music player you must edit build.prop files. Instuctions in post #218. Hope it helps.

this app affects battery life?
[G2 General] alex72:
Off course. Noticeably? I didn't notice but your experience may vary. Friendly advice; relax and enjoy your music with ViPER4Android audio effects. It's well worth it over extra few percentages of battery life. Life is too short. Enjoy it!
[G2 General] GibMcFragger:
What Alex said. I also noticed no increase, or at least not enough to concern me. The Snapdragon is fast enough that it doesn't break a sweat decoding audio. The increase in audio quality is well worth the minimal affect on battery life.

[G2 General] alex72:
It could be but it's not a rule. Actually, far from it. I would suggest to try different irs and find best sounding to your ears. Keep in mind that some members don't use irs at all. They tweak some other settings and best place to start exploring is official audio profiles thread. Link is in first post. Welcome to ViPER's Audio experience!
[G2 General] mannequin:
alex72, did you have trouble setting up the xhifi version? no matter what it was giving me driver issues. as i understand the development was stopped for it, still interesting to hear what it does.

Just got out of my ride after listening to some tunes and man does this really clean things up. Absolutely blown away by the sound coming out of my stock system. From soul to trance to hip-hop, it all sounds great. CLEAN CLEAN CLEAN. As if I couldn't love this phone any more....lol

I highly recommend that you read through the original thread and go through each option to see how it impacts the sound so you can tweak it to what sounds good to YOU. Very very customizable. Blows nooz out of the water, quite frankly.
[G2 General] alex72:
No, I didn't and I wouldn't recommend doing both because it would be probably overwhelming for that tiny speaker. Maybe somebody else did it but I don't think they choose to put 8dB boost on speaker in the app together with that other fix.
[G2 General] alex72:
I couldn't put it any better. I can't stress it enough how important it is to read first four posts in original thread.
[G2 General] vegetaleb:
Can you boost volume output on speaker and BT?

I will use my HTC Stereoclip with it,the One has a loud BT output
[G2 General] ericdabbs:
I just care about getting a boost in

1) speaker volume when listening to Youtube/Netflix, etc.

2) speaker phone volume during a call

3) headphone/headset volume when plugged into headphone jack.

If this ViperAndroid app can do all these things I just listed, I will give it a try.

Can anyone confirm if these 3 things?
[G2 General] alex72:
Yes. All three tabs (headphone, Speaker and Bluetooth) have same possibilities (options).

I wanna be clear. They don't have exactly same settings but all three use Convolver where you can use IRS files with volume boost. In starter pack and my attached zip you can find half of dozen +6dB IRS files and that is just a starting point. ;)
[G2 General] vegetaleb:
So you can reach S4 volume output for ringtones?
[G2 General] alex72:
I didn't try number 2 but for other two questions is confirmed to work from multiple sources.
[G2 General] alex72:
I don't know about that. I don't have S4.
[G2 General] ericdabbs:
I am curious if this app has something that can enhance the volume of the speaker phone. The only reason why I bring it up is because some people were talking about how the speaker phone can be louder since the stock values for the speaker for media, headphones, and speaker volume were toned down.

I guess if anything I could just use the fix in the other thread to modify the speaker phone values.
[G2 General] livebyknight:
I have a weird issue with mine.. It works on my loudspeaker but doesn't seem to change sound at all with my headphones.

Note I don't have the greatest in ears (shure se215ltd) but I expect to hear at least a small difference. When I check the driver status while listening to Google play music it says not processing. I followed every step. Any help?

LG G2
[G2 General] alex72:
Usually reboot helps things to settle down. Assuming you installed right drivers and everything else in driver status is on except processing simply tickling on/off while music is playing or starting and stopping music. Try loading different IRS file in Conveyor. If nothing helps try to reinstall drivers. Hope it helps.
[G2 General] lattiboy:
Yeah, I had to reboot twice for it to go, but MAN it is nice. The "viper clarity" setting set to XHiFi is

amazing

on a number of headphones (studio and earbud style). Perhaps not for audio purists (though it may be), this is some of the best DSP I've ever used. I'm using a kinda janky set of Rosewill stero type headphones to test.

I only have the main power option and the "Fidelity Control" options set. Specifically the XHiFi at +3 and VIPER Bass (natural) at +8 db and 60Hz. Switching it off to default really drives home how impressive it is at separation.

It'd be cool if people would post their settings and the speakers/headphones they're using to listen.
[G2 General] alex72:
That's a great idea and I would encourage people to post their favorite settings. Also, if could users report back which music player app works with ViPER4Android, that would be great!

Yep I got the service really cheap through ps plus. It had plenty ultra high quality tracks. It is very pleasant on this DAC which is not much playing compressed MP3s
[G2 General] alex72:
BTW, for me, it works with Play Music, Shuttle+ and musiXmatch. I didn't try anything else.
[G2 General] alex72:
I read somewhere that ViPER4Android works with Spotify but you're gotta change something in Spotify settings. Maybe is a same catch with MU.
[G2 General] JRJ442:
Isn't that one really old? You should use the one here on XDA. Pretty much does all that for you. You just have to select the sound quality you want..
[G2 General] alex72:
No trouble at all. Make sure you select Cortex with NEON driver. I'm still on CleanROM and using XHiFi as user app and FX as system app. Keep in mind, if used together, make sure you are charging your phone because this combination is battery guzzler. Serious battery consumption, even higher than GPS Navigation. I ended up using it in rare special relaxing occasions and while tinkering with settings. It's worth a try, for sure, but don't expect miracles.
[G2 General] ledvedder:
I just installed this, and when rebooting, my phone is just spinning at the T-Mobile white screen. It won't finish booting. Any ideas?
[G2 General] alex72:
It's just a regular app and I doubt V4A is cause of your phone not booting. Likely, culprit is something else.
[G2 General] ledvedder:
That's odd. I did a backup right before I installed VIPER. I restored the backup, and the phone starts fine.
[G2 General] alex72:
I agree. It's really odd. I read thousands of posts, here and in original thread, and never encountered post similar to yours. It could be superuser problem or conflict with some other mod. Do you have latest SuperSU installed? If you get it working, please post back so other members could know what the problem was.
[G2 General] JRJ442:
Probably just some data got corrupt somewhere. I updated an app in the Play Store the other day, once it installed my phone rebooted an got stuck at the boot animation. Ended up have to wipe and reinstall the ROM. What recovery do you use?
[G2 General] alex72:
You probably meant that you updated some other app through Play Store and had problems with it and not ViPER4Android because Play Store V4A version is 2.2.1.1 which is much older version than current v2.3.1.5

BTW, all Play Store versions of ViPER4Android are released by some other people and not by developer ViPER520 thus they're not supported. ViPER's Audio website Downloads section is place for supported stuff;

http://vipersaudio.com/blog/?page_id=48
[G2 General] JRJ442:
Yeah it was definitely some other app. I don't use that one on the Play Store. Just the official here on XDA. I was just pointing out that data can get corrupted by updating or installing an app if something isn't quite right, no matter what app it may be. Guess I should have been more clear. I actually had that problem a lot on my S3 with TWRP. Updated apps or installed them and got stuck. That's pretty much why I asked what recovery he was using.
[G2 General] alex72:
[MENTION=3520986]JRJ442[/MENTION] Thanks for additional explanation. I knew what you meant but for some new members it could be completely different story.
[G2 General] JRJ442:
[MENTION=652669]alex72[/MENTION] Sometimes when listening to music through headphones, I get a weird chirp/beep sound. Do you think that could be from kernel voltages too low?
[G2 General] alex72:
It could be but I really don't know. Try it as system app. You probably already did. Go back to stock kernel if possible. As you know, I am on stock based CleanROM and don't have those issues. Try different music player as well. Hope it helps.
[G2 General] JRJ442:
Yeah its already a system app. I'm running Mahdi right now, which is AOSP 4.4.2. I raised my voltages some and didn't notice it last time I listened through headphones. Someone that has a N5 has a similar issue and I was wondering if I should tell him to try that. You're a pro with V4A so i figured I'd ask you first. I'll give it a longer test later on and see if comes back. If not I'll suggest that.
