Share your Viper4Android Settings

So I thought it would be a good idea to have a place to discuss the settings we use on Viper. I know it's tough to lock down a profile that works for everyone, since we all use different audio accessories, but maybe those of us that have learned a thing or two can help out those who don't know as much. My setup is below and my UI setting is on expert. I've also attached my profile and several .irs files.
My headphones are just $12 Skullcandy Earbuds, I have it turned off for my phone speaker (Video sounds great but notifications sound horrible), and my Bluetooth is usually streamed though my car, which has a Rockford Fosgate sound system with Tweeters, mids, a 10in sub-woofer, but it sounds great through other BT speakers I've tried as well. Full disclosure: I use TEKHD's rom, which comes with other sound mods as well, but I only use Viper and Dolby, so YMMV and all that.
To use the Profile and .irs files (impulse response) I have attached, Viper's UI setting must be set to Expert and Convolver enabled. There will then be a folder named Viper4Andriod in your main storage, and in that folder there should be one folder called Kernel and another called Profile. Place the Kernel.zip in the kernel folder and extract it, and place the Audiophile 2.zip in the Profiles folder and extract it. You can then select any of the .irs files as your impulse response and Audiophile 2 as your profile.
Headset (enabled):
Force Enable V4A - Off
Playback Gain Control: Off
Viper-DDC: Off
Spectrum Extenstion: On - Strength: 1.0
FIREqualizer: On - Preset: Custom (included in attached profile)
Convolver: On - Impulse Response: Dolby Pro Logic II.irs (attached) / Cross Channel: 15 Percent
Field Surround: On - Field Surround Strength: Slight / Mid Image Strength: Level 5
Differential Sound: Off
Headphone Surround +: Off
Reverberation: On - Room Size: 25m2 / Sound Field: 5m / Damping Factor: 0 Percent / Wet Signal: 0 Percent / Dry Signal: 80 Percent
Dynamic System: Off
Tube Sound Simulator (6n1j): Off
Viper Bass: On - Bass Mode: Natural Bass / Bass Frequency: 40 Hz / Bass Boost: 13.0 dB
Viper Clarity: On - Clarity Mode: Natural / Clarity: 3.5 dB
Cure Tech +: Off
AnalogX: Off
Output Gain: -8.0 dB
Channel Pan: 0.5 : 0.5
Limit Threshold: 0 dB
Phone Speaker (Disabled)
Bluetooth Device (Enabled)
This setup is almost identical to my Headset setup but with the below changes
Equalizer is slightly different (attached profile)
Bass Boost: 14.0 dB
Output Gain: -6.0
USB/Dock (Disabled)
The sound I get through my headphones and the Bluetooth system in my car is awesome. I hope you guys can use this profile as is or at least as a base and tweak to your liking. Enjoy.
Special thanks to @vibrantliker for the Audiophile profile I used as my base and @drbveb88 for providing the .irs files.
Update: Several more .irs files can be found here: http://forum.xda-developers.com/showpost.php?p=65293899&postcount=6
Thank @drbveb88 for posting.

Nice thread buddy!? With so many options this will be great to see what people will share.
I do not seek credit for the irs files, i didnt make them just sharing them.
Dont have too much time right now but will be back to post my settings.

Thank you, sir.
I still had to give credit since I wouldn't have had the irs files without you sharing, so thank you for that.
I'm looking forward to seeing what you've come up with.

Doesn't enabling the Convolver disable the EQ?
That noise between songs is annoying! I installed my viper setup from here and it's not as bad: http://forum.xda-developers.com/nexus-6/themes-apps/viper4android-t2952137

I have them both enabled, however now that I think about it, I haven't tried messing with the EQ with Convolver enabled.
Also, any ideas what could be causing that noise? I haven't really tried to narrow it down since it doesn't bather me too much, but if I can get rid of it I will.
EDIT: Just confirmed that toggling the EQ with Convolver enabled does in fact affect the sound.

https://www.dropbox.com/s/bs9fp7swmydapif/ViPER4Android.zip?dl=0
This has about 40+ irs files in the kernel folder and my profiles.
Im sure it wont satisfy everyones listening taste but its a very good starting point.

I've figured out a way to get rid of the noise between songs. Just disable/untick "Playback Gain Control" that's it

Hmm. Maybe we could disable the playback gain control and then set the output gain to something lower than 10.5. Maybe 6.0 would balance it out a bit. I'll test it tomorrow.

Easy enough fix was just to turn off viper, the songs played for maybe ten seconds before it turned to loud screeching. I haven't change anything other than loading the files. Will mess with it tomorrow when I'm sitting in the car again.

I had the same issue when plugging my phone into my car stereo via AUX with the Audiophile 2 profile. Every time there was any sort of bass, it would sound all screechy and distorted. I turned off the convolver IRS "Dolby pro logic II" and all was good again.
EDIT: After looking around some more, sounds like the updated Viper app is causing issues with IRS processing which in turn creates the distorted sound. Not all IRS are effected though so I would suggest trying a different IRS that works until the Viper bug gets sorted out.

I guess it's one of those things that work for some but not for others. Maybe this setup only works on certain sound systems. I'd like to test with other BT speakers but unfortunately I don't have any. What's strange is that my BT setup and my Headset setup are almost identical and I don't have any distortion using either one.

@vibrantliker
I've worked out the weird hiss sound in between songs. @Lam pham was correct in stating it was the Playback Gain Control causing the issue. I disabled it and changed the Output Gain from -10.5 dB to -8.0 dB to make up for the loss in volume. I'll go ahead and update the OP.

How I increase volume levels?

I found the volume in headphones some low compare to my m2 aqua. I tried with Xposed modules like Gravity box and Volumesteps but for some strange reason, they make my music player crash (I use Poweramp) when I try to listen music. I want to increase the levels but i can't find the xml file to do it. In lollipop I remember there was a file called mixer_paths in system/etc but in marshmallow that file isn't there. Anybody knows which file I have to modify to increase the volume ?

In poweramp:
1) in the equaliser, try increasing the preamp level
or
2)in settings / audio / advanced options - turn on direct volume control
then try 1) again

You can use Viper4android and increase the volume gain. I'm sure that MTK EngineerMode can be added to the firmware, in my various tests I successfully launched it only one time by adding the app but my firmware was heavily modified and I can't repeat this since reflash, increasing the volume works and the sound was VERY high. But don't worry it's on my "to do" list

I've already have viper (the xHifi version) and it increase the bass but not the volume. Actually I tried with MTK but an error doesn't allow me to use the app (it said something like i don't have "mediatek chipset"). I'll wait until it works. Also, do you know what causes the strange crash that i described when I use Gravitybox to increase the volume levels? I really want to increase; I used it with other phones before and never had any problem.

The Mtk EngineerMode is not implemented in the firmware that's why you can't launch it. In Viper4android you have to switch the UI to "moderate" or "expert", you will have access to "master gate", increase "output gain". I can't help you for Gravity Box because I don't use it for that.

I have a VERY good news for XA and Ultra users, the MTK EngineerMode is back! :victory: (for rooted devices)
Guide and files for soon.

[ROOT][MOD] Xperia X Performance Volume Boost for stock config

What's bugging me about my brand new Xperia X? The overall low volume.
These simple tweaks, this mod if you may, simply modifies a few lines from the stock audio config files which, after a reboot make your speakers louder and headphones, a bit too loud (but I didn't hear anyone complaining about Xperias for being too loud lol)!
It's for rooted users only and for me it sounds a lot better than using (possibly) unstable sound mods instead of simply adjusting the volume on some pretty decent stock drivers.
***Tested on X Performance running Nougat. I've also got my hands on Xperia X Performance files which are pretty straight FWD see attach. Thanks @bkk99213 for testing and for the file!***​​​
Make a backup first or if you didn't simply put the original values back (82 for speaker lines and 76 for headphones). All that can happen if you modify the wrong thing is: Your settings won't do anything or you'll have no sound, that's why a backup is ideal.
Features:
Louder Stereo Speaker sound system wide;
Louder Headphone sound;
Stereo Voice-Speaker call - NOT TESTED! Keep a backup and please let me know if it's working;
Customizable as you see fit! Just stick to the already explored options.
Conflict-free tweaks - no additional files added, no nothing, just some modified lines - you can trust it .
Installation:
By flashing the .zip on recovery or with FLASHFIRE [press the red "+" button > Flash ZIP or OTA > leave the options as they are and Click on the "done arrow thingy".
Manually copying the file to /etc - DO NOT forget to set the right permissions (RW R R). Please take a look over the Permissions.png screenshot in case you don't know how to set them - you long click on the file, then go to properties and you'll see the permissions button.
Do it yourself - there's a guide down bellow.
In the download section you'll find:
>>Flashable! already modified "Xperia X P Getting Loud.zip" with: SPEAKER values - 84 for both RX7/RX8 and HEADPHONE values - 84 for RX1/RX2.
>>Flashable! Stock Values - it's the stock file unmodified.
>>NON-Flashable! zips - there you have 1 zip for the modified file and the stock one so you can place it manually via ES file explorer or the explorer of your choosing.
**And some screenshots that are pretty self explanatory showing you what modifications need to be made if you want to do it yourself.
DIY Guide (using ES File Explorer):
You're probably acquainted with ES File Explorer so it should be pretty simple. The modifications I made were done with ES (it has an built-in editor).
1. Make sure the Root Explorer toggle is On - it's located in the Tools tab as you swipe the left side of the screen;
2. Go to the root of the files where you'll see folders such as "data; dev; firmware; storage; system; etc" go to "etc" folder and scroll down till you see the mixer_paths files;
3. Open "mixer_paths_tasha" and at the prompt, select ES Note Editor - it's a huge file so tap right above the navigation bar! A bar with percentage should show up - it will help you navigate through the file;
4.1 Speakers - Get to 45% of the file where you should see the path for "speaker", ctrl name RX7 and RX8 with their stock values - modify the values as you please but please don't go over 85 - sound will be too distorted;
4.2 Headphones - Go to 57% of the file - you'll see "headphones" path - ctrl name RX1 and RX2 - modify the values but anything more than 84 might be too much.
5. Save and reboot. If you choose to modify the files on a PC make sure to set the permissions when you put the file back. Otherwise bootloops might occur.
*Stereo Voice-Speaker call is untested but in theory it should work, as it does on my Xperia X. I added the second channel to the routing - screenshot bellow.
**Stereo Ringtone-Speaker - WIP. I'm currently stuck so feel free to jump in and notify me via PM.
***Internal players such as Music, Video, ringing and notification will try to compensate the sound so it might not be as loud as expected. But try a youtube video and you'll notice the difference.
***Do not attempt to modify something else unless you know what you're doing - on that note, make a backup first. In my first attempts I lost sound device wide with FC for sound effects apk.
***Do not go over the values I imputed (84 for speaker and 85 for headphone) - apart from the distortions that will occur because of the louder volume the internal DAC might not be able to reproduce the sound at such intensity - in my tests one of the speakers was shutting down. Again, no harm can come to your device but don't push it.
***I saw a lot of sections for hi-res headphones, Noise cancelling, etc - I did not explore those options because I don't have the means to test it. Any input and contributions from you guys are most welcome.
These files control the volume output for digital / analog which means it's a non-intrusive way to change volumes with no harm for the device. If volume limit exceeds the capacity of the speakers it will sound bad but there is no chance for physical damage.
I'm coming from a highly modded Xperia Z (that phone saw some torture) which made use of the earpiece speaker for stereo, and even if the speakers aren't designed for that output they are louder than the X which packs pretty decent speakers. This is the mod that gave me the idea: http://forum.xda-developers.com/xperia-z/themes-apps/mod-stereomod-xz-v1-1-t2835995

Yes that's why it's a guide-ish. Files are different still... Traditionally with Sony, you should aim for the largest file. In your case the right file should be "...tasha" file. If you want you can send it to me or try it yourself. Keep a backup. I had no bootloops (so there's nothing to fear) by modifying what I shouldn't (and i had a dozen of tries). All that can happen if you modify the wrong thing is: Your settings won't do anything or you'll have no sound, that's why a backup is ideal. PM me. I'm curious about the file and results.

That's device specific. On my X 84 is just the right amount. I'll make another zip with 83 values. That's only one step over stock.
At least headphones are loud and distortion free. I noticed some good amplification on those. On my old Xperia Z I could never have such a powerful sound without signal cutting off on one of the channels.
Correction. The file had 85 for speakers. I'll put new zips with 84 soon.

Looks like it's mixer_paths_wcd9335.xml at 148.6KB. Both RX7 and RX8 are at 82 stock (under path name="wsa-speaker"). How much past the original values are you pushing these things, 2-3? Do these values boost the in-call speakerphone volume as well?
Unrelated, does anyone know if this XML has anything that could be modified to get get both speakers working when using the in-call speakerphone?

I am pretty sure both X and X compact use the same HW - it seems to be the same file and wsa thingy - check my thread for X - https://forum.xda-developers.com/xperia-x/themes/xperia-x-mixerpaths-volume-tweaks-tank-t3525691
it is possible to modify the call speaker - and there are more things to add like stereo for that one. But going over default for one speaker can get voice distorted. And if stereo is applied there, than microphone quality will drop a lot. There's a reason why the call speaker is mono - so that the mic on the other side can catch most of the sounds. At some point maybe I'll look for a hook for stereo.

Awesome! Bumped the speaker and headphone values up to 86 and 85 and all I can say is wow! Made a huge difference!
Do you know which lines specifically control the in-call speaker volume? Makes sense about the mono audio/mic pick-up, however it'd be great to at least increase the volume.

Adding stereo speaker to phone call is a bit tricky as far as I remember, especially without a recovery. Hopefully I'll have some spare time to look over it or at least identify call routing.

Would it be easier to just increase the in-call volume and leave it mono? I'm guessing that there is a similar RX line that can be bumped up a few values to increase the volume.
Under <path name="voice-speaker"> there is a line <ctl name="RX8 Digital Volume" value="82" />. I'm guessing that may be it?

yup, that should be it. I'm advocating for the stereo because stock values already distort a lot on speaker call

[UPDATE] Please check the updated thread for Xperia X. For you, modifications should be easier to learn from there. Stereo Voice-Speaker added - no need for volume boost. https://forum.xda-developers.com/xperia-x/themes/xperia-x-mixerpaths-volume-tweaks-tank-t3525691

Question about increasing volume.

Hi, Im not sure if this is right place to post this. I've never rooted phone before, and i want to root my Xperia Z5 Dual, only because i heard you can increase volume. This phone has low headphone volume IMO. i can listen without problem in quiet places but sometime when im outside i cant hear song even in full volume. even my Iphone 4 had louder volume. So what i wanted to ask is if i increase volume when i root, will it decrease sound quality? there are some apps that dont require root to increase volume but then phone sounds terrible so is it worth it to root my phone for this reason? I'm aware i might brick the phone too.

AFAIK you can increase the headphone volume by editing "root dir/etc/mixer_paths.xml" and finding <path name="headphones"> and editing values from there.
I'm not exactly sure what values to change as I had only done this a long, long while ago with my old Z3. A quick google search will get you going though.
Rooting shouldn't decrease quality but unlocking the bootloader MAY (and I mean may because I am not sure what unlocking the bootloader disables on this specific device) disable some sony sound 'enhancement' software on the stock ROM.

Another option (and the way I do it) is to root using magisk and install magisk manager. Then through the manager you can download and install modules. You'll want to install the "ViPER4Android FX" module by ViPER520, ZhuHang, Ahrion, and Zackptg5. Within the viper4android app you can set various sound enhancements. Just looking through real quick I can see output gain and playback agc settings.

What is the difference you see

There is no sound boost when ther slider is all the way to the right for clarity as well as sound.
Even if there is a sound boost,it is very very small

Depends on a lot of things actually...what app were you using while trying to boost sound through the video toolbox?, what were you listening it in..I mean , was it via 3.5 mm jack headphones or the inbuilt speakers or via bluetooth? All will give different reulsts and also depends on whether any other sound settings were tinkered as well.

I used youtube and i tried both using headphones as well as inbuilt speakers,but the volume more or less remains the same.

Ok..So were you tinkering with the equalizer and other settings found in phone settings--->sound effects prior to doing this sound boost or was it in memory?This happens to me quite often when I play around with both settings..i.e. the sound effects settings and the video toolbox sound clarity and volume boost. The only way out for me was to clear the memory though recent apps and start the youtube app again and this time the sound settings in video toolbox actually works. Dont do both at the same time if thats the reason why its happening ( make sure both the sound effects and the youtube app is cleared from the memory). Best identified through headphones. On a side note, best setting for me via the video toolbox sound boost is clarity on 2 or 3 and volume on 2 or 3.

I haven't played around with the sound effects in settings yet, it's set on smart preset already,when you increase the sound and clarity can you actually sense the increase in sound quality or is it minimal?

Marked difference... quite an increase in sound quality...BTW mine is set on Video/Voice most of the times in Preset. I find that best in terms of loudness and have tinkered with the equalizer giving it a bit of bass. But thats about it
Edit Update: The video toolbox sound effects have little to no effect when the preset is kept in smart. Video or voice gives a good difference. Kindly check and confirm if thats the case.
