I've just tried the Q-Clone, and by far it's the best!! I can't really describe it, but it's the best for Pop/Rock genre. thank you for these wonderful work!
[Android Software Development] BSDgeek_Jake:
Enjoy. Thank you and all the users for Great Appreciation. Cheers.
[Android Software Development] sjknight413:
None of the qclone or dolby profiles are working for me? except dolby 5 and dolby headphones.

every other profile i have works fine but when i switch to one of the dolby or qclone the sound does not change.

anybody know what's up?
[Android Software Development] alex72:
It's a known problem for some people who installed V4A as system app. Try it as user app.
[Android Software Development] SSS Desire:
+1. I've the same thing. Any clue here? I'd really like to test them out
[Android Software Development] Migou67:
Try to clean up the directory /sdcard/VIPER4Android/kernel and just place the qclone files without aditional directory and give a try.

I had the same problem before and now is working fine for me, I have the app as system on a stock 4.3 Note2 with the latest version of Viper.
[Android Software Development] sjknight413:
Tried that but still nothing.

I can't set v4a as a user app because it seems to get killed off every two minutes on cm11
[Android Software Development] Migou67:
After switching between my profiles just now, I have the same problem as I had before and you have with Qclone

I have buy Z-Edition packs from ZhuHangs and they are working perfectly fine. I dont know what happen with this Qclone files. BBE files are working for me but Tracks no.

I have also problems when running v4a in user mode, the app "reset" regulary and is annoying for me, as I use Output Gain to reduce volume.
[Android Software Development] acelim23:
Thanks for sharing. Dolby, Tracks, Qclone all are great IRS. Most of the time using Qclone compressed or Tracks DeEssed Master1.. Will sure wait for more of Qclone.. Happy weekend everyone
[Android Software Development] venkatp:
Doesn't the latest version support IRS samples? I don't see any option in v4a 2.3.2 to enable them

Installation of the latest Viper app

I recommend against updating the Viper app for those who are wondering, too many issues going on with it. Stay where you are!
[Android Software Development] sjknight413:
Issues like what? Newest version has been absolutely fine for me, even got the qclone irs' working finally!

I would definitely update if you haven't already
[Android Software Development] 2545:
Yep, latest version works great for me too. Actually, I've never had any issues with my note 2 with any of my tw roms.

Best IRS

Awesome.. Feeling the clear thunder sound.. Master Class IRS.. :laugh:

Thanks bro for such a great work.. This is the first time am hearing such a loud and clear and awesome sound from my phone.. :laugh: :good:

Have 1question..what is the diff bet high quality and power saving driver in the latest VIPER. Choosing power saving affect sound clarity?? My mobile having 1GB Ram and 1.2Ghz Quad-core Proc.

Thanks in advance. :good:
[Android Software Development] ArtfulDodger:
Well for one it's hard as hell to update without doing some steps I described over in the Viper thread, least for me. Also I noticed some skips and cracks in my music when using it. The whole experience with the update was a pain in the a**. And again, I'm been using the app for quite some time so I know the ins and outs pretty good. 2.3.1.5 works perfect and that's where I'm staying.

I did find out last night that the update does get Viper fully working on 4.3 ROMs, at least CM10.2.
[Android Software Development] They Drew First Blood:
Super Quality

If I had your device I would definitely go with Super Quality. There are four modes listed in the V4A official thread:

No modes: For processors with or without VFP .

Battery Saving: Available for all processors with NEON.

High Quality Mode: Available for processors with NEON.

Super Audio Quality: Available for processors with NEON.

My device is a single-core 1GHz CPU with 512MB RAM and I use Super Quality. I have not tested each mode for comparison, but my understanding is that Yes choosing battery saving will affect quality. If there was no difference in quality and battery drain between the four, then it would not make sense to have any more than two modes: On or Off. Go with Super!

[Android Software Development] FuMMoD:
Ok so after reading all 26 pages my question has not been asked. When I'm in the convolver screen in expert, I notice an extra option. Has anyone used this cross channel setting? Can anyone fill me in as to what it does exactly?
[Android Software Development] eushaun99:
I don't know how to explain it. Its like the effect of the IRS. If you set it to higher, the effect of the IRS will be stronger.
[Android Software Development] FuMMoD:
Ah ok so pretty much tune to personal preference?
[Android Software Development] eushaun99:
Yup
[Android Software Development] Migou67:
I think it's used to center the sound, to give you a more "speaker" presentation, but at the detriment of the soundstage.

I do not use it
[Android Software Development] FuMMoD:
I notice a more powerful sound stage when I use it though so I guess it depends on the irs.
[Android Software Development] los1010:
What IRS is that one?
[Android Software Development] dannyella:
The IRS do not work when v4a is installed as system app.. Or is it just me? :(
[Android Software Development] FuMMoD:
It's an irs specifically made for the vmoda m100 headphones. It's made by the OP, I'm pretty sure.
[Android Software Development] los1010:
Oh ok thanks
[Android Software Development] gado45:
Actually for some devices like nexus 5 stock these irs 's won't work as a system app.. Not even one.. Go as user app
[Android Software Development] dannyella:
Finally got it to work as system app on my nexus 5 by using titanium back to convert it to system app. Pushing it in /system/app via root browser causes the issue with irs not working... Strange

Edit: When I update my rom the issue is back.. :(

[Android Software Development] thoiloidainhan:
Making viper a system app doesnt help with the problem of viper being killed in the background (my experience and many other from viper thread). Making it a priv-app on the other hand is the solution but some IRSs stop working so yeah big bummer
[Android Software Development] dannyella:
mine is installed as system app and it doesn't get killed even when i long-press back to kill it...but the irs here are not working. Only Amphibionic 2 works..

Important Words from BSDgeek

Important Words from BSDgeek

(these words are just my review and based on my testing using some set of devices and android family, your results might vary.)

It seems that many of the users are not able to hear any differences or unable to load or partially load my IRS...

Please Note that CM users or variants of CM are not fully supported due to issues with the Audio Interface with OS and V4A FX app (I know it exists and can be searched through Device specific CM Threads). Few say it work but Few say it wont... Device to Device it vary... there are variations...

STOCK users are good to go from 4.0.x to 4.4.x 100% Working.

My tests (based on STOCK) using Samsung Galaxy S2 (i9100), Samsung Galaxy S4 (i9500), Micromax Canvas 2, Micromax Canvas 4, and Nexus 5 shows that it work without any issues. Everything is working and melting the ears and The Ear factor is right there.

Please follow these to troubleshoot, if nothing else works then ask the App Developer for issue and the resolution.

1. Is your V4A FX installed as user or system? (should be system)

2. Is your V4A FX Driver installed correctly? (should be system)

3. Are you at NEON or VFP? (should be neon)

3. Is your Convolver enabled? (should be ticked)

3. Are you able to load some IRS through Convolver? (should list IRS)

4. Are you able to hear sound differences when IRS is loaded? (sound change)

5. Are you able to hear some of my IRS? Which?

6. Are you able to hear all of my IRS? OK So We Are Good.

Hope this helps. :good:
[Android Software Development] ArtfulDodger:
I mentioned this issue a while back and no one else ever seemed to have the problem. What works for me is just uninstalling ViPER4Android and reinstalling from scratch (not using the TB app). Also, and this is just my opinion, it's essential that ViPER be a system app in order not to get constantly killed by android memory management.

That being said the new update has really brought BSDgeek_Jake's Dolby Pro Logic IRS files to life. Just amazing stuff.
[Android Software Development] 2545:
This particular IRS seem to be very gain heavy and I need to set my output gain to - 14 dB or more as the volume is so loud; similar to QClone which I also prefer. What is your experience/settings.

Works great on my device btw!

Sent from my SAMSUNG-SGH-I317
[Android Software Development] ArtfulDodger:
Wow, I'm quite the opposite. I have playback gain at "4" and output gain at "-3" ATM for the Dolby package. I tend to change up a bit, but if you are interested in my settings, you're welcome to download them and try them out for yourself. Just save the file to the Viper/Profile folder, then load the effect setting in the Viper menu: https://www.dropbox.com/s/55u3l9xfhybfhaw/Dolby%20Pro%20Logic%203.prf

I'd list them but it's so lengthy it's just easier to share the profile.
[Android Software Development] They Drew First Blood:
Dolby high gain

On my cheap JVC earbuds, I need to set the volume very low with the Dolby irs due to that high gain or it would blow my eardrums out. On my nice Sennheisers, the Dolby is great for that extra gain and I don't mess with it- I think it provides a better preamp signal, or something. Your results may vary according to your individual setup.

Android 4.4.2 .flac audio issue

My post has been buried in the ViPER main XDA thread, so maybe it will help some users here:

The issue only affects .flac audio and currently can only be avoided by using a ROM with the fix- I had VLC player recommended but had no luck there. Users experiencing crackling with other audio files like .mp3 should be able to resolve it with the various troubleshooting steps mentioned on the ViPER Audio website or XDA thread OP.
[Android Software Development] 2545:
I'm tweaking my settings again with Dolby IRS file.

Just to be sure, which one is "BSDgeek_Jake's Dolby Pro Logic IRS file" or the popular Dolby Pro Logic file?

There is one download link (post #182) called "Dolby_Pro_Logic_II.irs" and then there is the zip file in the OP which has eight presets.

Which one you guys using?

[Android Software Development] mliou:
Try pushing it to user app (I used titanium). I managed to get it to work. Then I pushed it back to system app (via Titanium again) and it was fine.
[Android Software Development] BSDgeek_Jake:
Its seems few users need to push it to 'system app' and rest need to install it as 'user app' to make it work. Looks like Google playing with Audio sub-system every intermediate releases and changes are not commited in changelog. I think dev should point out two ways of installation for easy of users.
[Android Software Development] ArtfulDodger:
Only problem is if you install as a user app it will constantly get killed by android memory management. The only way I've gotten Viper to work as it should is as a system app. Otherwise it will be dead every few seconds/minutes and you have to open it again to get the effects back. You can probably lower minfrees but it still won't stay consistent like that.

I should also note when I tried that, your IRS still wouldn't work. Only fixes I have found are ROM changes or reinstalling the app and starting over. Do you think it's the size of the files or something that could be the cause? I'm grasping at straws because it seems there is no rhyme or reason why they work on some ROMs and not others.

I reverted to an old 4.2 version of Carbon last night and once again your IRS won't work. It makes no sense being that's an older android version. Stumped.
[Android Software Development] metaphz:
Confirmed working on Hyperdrive S4 Twiz ROM and Galaxy Tab3 8.0 running CM11.

Both required System App setup.

Be advised on 4.4 you need to copy APK to /sys/priv-app/ NOT /sys/apps.
[Android Software Development] crawler9:
All of your IRS work great for me on my m919 (T-Mo GS4) on just about every ROM I've tried recently. I always install as a user app (at least since somewhere around V4A 2.2.0.1) and haven't had any issues with your IRS that I can remember. V4A doesn't get killed and everything works flawlessly at this point. Currently, I'm on CM11 nightly (with standard built in Superuser; haven't needed to flash SuperSU this time) + FX 2.3.3.2 (user) + Super Audio Quality.
[Android Software Development] BSDgeek_Jake:
For All Users:

Answers are "Just Test The Variations" like "system app" or "user app" or "priv-app", exclude "FX" from "Task Killers" or "Memory Management Apps".

One of them will defenitly work unless your ROM is very much messed up which i dont think the reason. Anyways... you should also as the FX App dev for the issue. Since IRS are Sound Samples and FX Convolver need to translate the Sound so might be an issue or bug with FX or Android Audio Interface or the Software Adaptor...

Android 4.4.2 issues

What has worked for me:

Install XenoAmp to /system/priv-app. --Xeno v.310

Install ViPER FX to /user/app. --FX v.2.3.2.2

This configuration works with all IRS files so far (and I have many from BSDgeek_Jake and Zhuhang)- except the one file I have issues with is Ambiophonic Preset 1.irs. With ViPER in /system I could not get it to process at all. In /user it has been working flawlessly, not dropping out or getting killed. I have ViPER set to High Quality because on my lower-end device Super Quality takes a bit too much CPU. Still sounds marvelous. Android 4.4.2 (AoCP), Samsung Captivate i897. The irs file I have been using and loving recently is Ambiophonic Preset 3, thanks again BSDgeek_Jake. :highfive:

Additional info: SuperSU 1.91, Greenify, DS Battery Saver (aggressive), Killjoy mod (no dnsmasq), Turbo Boost mod (512mb swap /data)

They're two files (rename to .irs). But is one Left and the other Right? And if so how can they be used if V4A only allows loading one .irs file at a time?
[Android Software Development] churapa:
You don't have to rename anything, IRS can have either irs or .wav extension, the software recognizes and applies either of them.

Check page one of the OP here:
[Android Software Development] cdkg:
The mention of the irs vs wav is a good point. There was a time v4a didn't view .wav

What about the "R-XF" and "L-XF", do they stand for right/left?

Super/High quality ViPER FX driver

Give High Quality a try, then- I have been using that for the past week and I can't really tell a difference between High and Super, to be honest, where audio quality is concerned. I think it uses less battery but I have not been closely monitoring it for battery usage. :good:
[Android Software Development] Kamau54:
Ok, help out a complete newbie on this.

These IRS's are nothing more than presets, right or wrong. I'm still trying to understand the use for them, even though I've got a few in my phone. I try to hear the difference through my headphones, but it's hard to really tell. Maybe I'm expecting too much.

[Android Software Development] BSDgeek_Jake:
Y you want it in 48000 and i dont know if it's supported by FX. The standard is 44100.
[Android Software Development] BSDgeek_Jake:
More than EQ Presets. IRS are sound samples which almost imitate the characteristics of Real Equipment/s or Environment. IRS are usually named after the Original source to identify as is.
[Android Software Development] BSDgeek_Jake:
SQ is much higher than HQ but drains the battery faster, for me 2hours with all settings in FX drains 20percent. You also need High Quality Earphones/Headphones to hear the difference and some amount of expert ears. Might vary Ear to Ear. Some will Feel and Some will not...
[Android Software Development] LibiSC:
Nexus 5 supports it... I read somewhere that at a different bit rate the it's won't work as 100% intended
[Android Software Development] They Drew First Blood:
SQ v. HQ

Guess my Sennheiser HDR-120 headphones aren't high enough quality... :crying: Or I have beginner's ears. Oh well, still sounds amazing! Other than the mids and highs going all to hell once the bass kicks in- maybe I need a new set. I can't afford any audiophile caliber equipment anyway. Some day- I'll probably be old and deaf by then- but some day. :shrug: Love these HD IRS samples. At least with the Sennheisers I can just load the convolver and be good to go. Last week it was Dolby Headphone, this week T-RackS Compression, week before was Ambiophonic Preset 3.

Question... how do I install the driver as a system app? I installed the app as a user app but moved it to system with an app. Then I installed the driver, but I don't think this is the correct way.
[Android Software Development] They Drew First Blood:
ViPER as system app

I don't see why that wouldn't work- are you having any issues? Also depends on what version of Android you are running, I guess. I am on Kitkat 4.4.2, and I just installed ViPER FX normally as a user app (/data/app) and it works fine. My media player XenoAmp I installed in /system/priv-app on the other hand. On Android versions below 4.4 you can install it in /system/app because /priv-app did not exist yet.

My procedure for Xeno was to use Root Browser to copy the .apk to /system/priv-app, and again use Root Browser to change permissions on the .apk to match the other files within that folder. Then open the .apk through Root Browser which began the installation routine. It seems like it depends on what ROM you are running for whether you need ViPER in /system or not- in my setup I do not. :good:
[Android Software Development] 93Akkord:
Looks like I got it fixed, but when I use the Dolby Pro Logic II 2.irs I have this annoying noise in the background. Its very light, but if you listen you can hear it. Doesn't do this with non dolby irs's. Any ideas?
[Android Software Development] Gamer015:
I may be too keen on this, but I really want to ask this one.

most of us know that most songs especially rock genres usually uses the left and right channel/speaker(I don't know how to say this. lol), usually I can hear the lead guitars on the left and bass/rythms on the right. but I noticed something on V4A when I listen to my songs, or when try to listen to just one earpiece, they're all pretty mixed up as one and there are no distinct or unique sound for the two channels.. or should I say that there are no alterations I guess.

I don't know if this a known issue at all.. I'm really glad to know if anyone can help me with this.
[Android Software Development] LibiSC:
What you are describing is called stereo width... I feel it normal... In convolver settings there is an option to mix the channels
[Android Software Development] Gamer015:
thanks for that info.. now I finally know what was that.

maybe the problem is on that convolver, I maxed it out to 80%.. I'll try tweaking my V4A again later. :D
[Android Software Development] They Drew First Blood:
Cross-channel

Definitely, that is exactly what your issue is right there. Set your Cross Channel back to 0% and you should hear a huge difference and get that separation that you are used to. Raising that cross-channel value will take away the normal stereo effect and start shifting towards a mono effect- which means: if you raise that cross-channel it is basically going to stop outputting left and right channels separately to each ear, and start mixing the two and outputting the same sound on each side instead.

The cross-channel can be used in small amounts to bring the center vocals a bit more up front...how to describe it...bring the sound a little bit more to the center of your head...? If you feel there is too much of a surround effect you can raise the cross-channel to bring the sound back to the center. Personally I leave the surround options off and the cross channel at 0% for most of the music I listen too. Some music sounds neat with them enabled at some level, though. Depends on your listening preference.
