[MOD][Audio] Stereo Mod for mi4c

Hi everybody. I've ported a mod for our device that allows to reproduce media through the main speaker and the earpiece at the same time, giving a truely sensation of "surround" sound.
Features:
"Dual" speaker
Source:
https://github.com/kevinkvothe/Libra-Audio-Mod
Feel free to contribute to this mod.
Bugs:
Test and tell me.
It's reported to work on aqua (Mi4S). Needed to change permissions to 777 (read-write-execute). You can do this on almost any root explorer you find, I personally use ES File Explorer. (Thanks BlackXhorneT)
Credits:
sshafranko, as I took his mod to modify our source. :good:
Contributors:
kevinkvothe.
This mod is diretly ported from:
http://forum.xda-developers.com/nexus-5x/themes-apps/mod-surround-sound-testers-t3252659
Warning! Not tested on 5.1, I just report to work on CM based 6.0.1. I'm not responsible in any way of any damage that happens to your device if you test this mod. Do it at your own risk.
Installation:
For now, replace the stock mixer_paths.xml placed on /system/etc (you'll need a root explorer) with the one I provide in this post. Remember to make a backup before. :fingers-crossed:
Version Information
Status: Testing.
Current Stable Version: None by now.
First Release Date: 2016-06-13
Created: 2016-06-13
Last Updated: 2016-06-13

Reserved.

Tested on Aqua,
This broke the ability for me to use any app that uses audio (youtube/apple music/stock music/mp3's in es explorer...) I've restored the old stock file and it's back to normal but that was quite a nasty result.
I think this needs more testing for general release and is not for aqua.
Otherwise, love the idea. If you get it working I'll happily try another build as I know restoring the original file works just fine. Good luck with the project
---------------
EDIT:
This may be a permissions issue as its set to 660 rather than 777. No file manager I've got will successfully change this over (root explorer, total commander, es...) so this may need to be done before putting in /system/etc/ in order to work correctly. Any suggestions on a chmod 777 app to try?
---------------
EDIT 2:
confirmed chmod 777 did the trick (permission change worked from /system/etc/ folder, but NOT from download folder. Seems to work! Apologies for my earlier scepticism. Interested to see how this will sound (can't really test as I'm currently at work).
Should be interesting . Well done!

Thanks for your interest! I've already updated the post with the permissions info. That's strange, though, as in libra it works just fine with rw-r-r permissions and 777 is not needed.
Hope you enjoy it!

Dude I like it a lot! Just watching YouTube and it sounds so much wider. Quality is ace too. Not bad!

Hi tried this on mi4c running ts cm 13.1 with permission set to rw-r-r works! Thanks ?

Thank you! This works perfectly , but unfortunately for me the speakers , headset and earpiece speaker too quiet . What values ​​do I have to change in order to make the louder?

It works flawlessly ???? Keep it up on my MI4C. Good Job ????????????

works only for android 6 mm?

To increase stock volume you should modify the RX1 or/and RX7 Digital Volume on the section <path name = "speaker"> or <path name = "speaker-gain-default">.
Yes. at least for me it works fine.
Regarding the android version, I've just tested it android 6, but feel free to try yourself and report back.

Same as I said in the previous post with RX1 and RX2 in "headphones" section should work too.

I tried this mod in miui.eu last stable rom and it works but the front speaker sounds terribly distorted, so I had to go back to previous xml file.
Maybe the front speaker is not capable of reproducing sound with the same volume and fidelity as the main back speaker?
Thanks for your work anyway!

Ofc, the front speaker is not designed to perform like the main one. This mod only provides a way to send media sound in a low volume through the front speaker, not to use it as the main media player.

I undestand that, but with the mod (at least in miui.eu stable) the sound is terribly distorted.
Maybe there are some gain parameters that need fine tuning?

Anyone given this a whirl on cm14.1?

Works great on cm14.1
Is there anyway to turn the stereo effect off and simply have the front speaker repeating the mono signal?
I find that many songs don't sound right since they pan a significant instrument to one side, and when that is on the front speaker it can change the way a song sounds.

Will it work on resurected rom?

Please can you help to make this MOD work with mi4i. I beleive the hardware other than processor is the same used in mi4c.

greatly works on aicp rom
but, is it okay to use the front speaker? and what happen when we make a call?

You download viper 2.5.0.5 and Dolby from magisk(cuz viper won't work without Dolby, idk why), then you unpack this zip to the internal storage, open viper, swipe from left to the right, click load effect profile, turn off then turn on "master power" on headset list and enjoy

There's about 50 different DDC files included for these earbuds. Which one(s) are the best to try?

I found a new solution. Install viper (on magisk 16.0, cuz won't work on further versions) and then audio modification library. Then just apply the profile and open equaliser (idk why but equaliser won't apply without opening it)

This will install viper and driver properly...
https://forum.xda-developers.com/android/software/sound-mod-viper4android-oreo-t3734107/page13
And all modules working

not bad once i turned the output gain down abit im using V1 the first v1 with Soundalive 4k edition, dynamic system unknown 2 at 14%, base at pure 100hz at 8db, clarity hifi 3.5db masyer gain -3.0db

Just want to say a big thanks for the vdc, I really like the v1 but can't vote for the v1 on poll got the "test" word
v3 is clearer but I think it is lacking treble, base is good tho

I checked DDCs using FLC8s on silver cabel - the most natural sounding setting is V1 (as mentiond above). Would reccomend to change Master Gate (Limiter) -> Output Gain to ~ -6/-5 instaed of -20. With the rest I just started experimenting.

Sorry for reviving an old thread, just wanted to say that the included kernel profiles are great in the zip. I am using a Surface Book with W10 v1809 and V4W. (For those wondering how I got it working use https://github.com/alanfox2000/non-official-viper4windows)

[SOUND MOD] [MAGISK] Viper4Android with included settings

After trying out a lot of different sound mods and apps and patches I always came back to Viper4Android. Simple to use, great sound quality and a lot of customization.
Steps:
-Extract the attached IRS.zip into Android/data/com.pittvandewitt.viperfx/files/Kernel (For Android 11 follow this tutorial)
-Install latest Viper4Android apk (Download here), open it, grant root access and install the drivers.
-Reboot the device.
IF THE MOD IS NOT WORKING AFTER REBOOT TRY SETTING SELINUX MODE TO PERMISSIVE WITH THIS APP AND/OR INSTALLING AUDIO MODIFICATION LIBRARY MAGISK MODULE
HEADSET
Go to Headset and enable the Master power switch, I suggest you put on your headphones now so you can hear the changes in the sound yourself and tweak them to your liking.
My settings are:
Master power: ON
FIR equalizer (enabled): Preset: Acoustic
Convolver (enabled); Impulse Response: IRS.irs (copy IRS.irs from the rar into Viper4Android/Kernel); Cross Channel: 60%
Dynamic System (enabled); Listening Device: High-end headphone (v2); Dynamic Bass:7%
Viper Bass (enabled); Bass mode: Natural bass; Bass Frequency: 115 Hz; Bass Boost: 3.5 dB
Viper Clarity (enabled); Clarity mode:Natural; Clarity:3.5 dB
Auditory system protection (enabled); On; Binaural level:1
Feel free to share your own settings in this thread!

Thanks to @sauliiin for his profiles:
"Here I share a lot of profiles and some other stuff for Viper4Android.
Just download, copy it and replace viper4android folder, close and open viper and choose your desired profile. My favorite is "Saulin", that is based on "V4ARISE".
Try and choose the best for you! Peace out!

Really thank you!
What about speakers? What settings would you suggest to get maximum loudness with minimal distorsion?

I find that different headphones require different settings, this setting could sound incredible to you and just "meh" to me, so I think everyome finds their own but thanks for the effort.. maybe everyone will share their settings in this thread and we can find inspiration?

No problem, I really haven't tested any settings on the speaker, as it's fragile I think and could break easily if you push it too hard, it's fine as is to me. If you find good settings please share it with us in this thread

I fully agree with you on this one, that's why I suggested putting the earphones on and trying the settings in real time so you could adjust it to your likings. However, over the past few years and dozen on earphones I owned this settings were kind of the same, only the values changed. Great idea with the settings sharing, I would like to see it happen

works on PIE 9.0?

Yes, with Magisk 17.1

Copied most of your settings!
A really improvement! Only convoler didn't worked... It gave me a strange bass... Like a broken speaker
The rest was good, just some adjustments for my taste!
Thanks for sharing! Viper4Android is like black magic, it's outstanding what it can do! It makes a cheap earphone looks like a JBL one
Don't know how people live with out it! It's one of the thinks that everyone should root to have

Installed and Everything looks perfect for me. Thanks

Viper settings highly depends on the pair you own. There are no universal settings for all drivers. But thanks anyway. Ask people to share their profiles too. :good:

Check few posts earlier, I adressed this.

V4a 1.7.2 was working perfectly. After upgrading to 1.7.3 it asks me to install drivers and doesn't work. Any fix? Or, does anyone have the 1.7.2 zip?

Guys I've experience weird sound on WhatsApp audio when screen is off or app in background. Seems like audio in slow motion. Can you try to play some audio message and switch off the screen or put WhatsApp in background and listen if the bug reproduce.
Thank you.

I also noticed that if Convolver is ON (with the provided BBE 2.IRS file applied) there is a little audio lag in general. You can clearly see it in videos through lab-sync.
I think that the postprocessing refinement is so huge that it slows a bit the final output

OnePlus Bullets Wireless Viper4Android Profile

By default bullets wireless sound too flat, their bass response is too low when streaming music, I connected them to my iPhone and saw that with the right Equalizer settings they sound awesome, given that iPhone sound processing is awesome, I tried to replicate the same in Viper4Android.
This
profile Improves Audio listening experience and bass significantly of your Bullets. If you are using Viper4Android then you can get the best of the Bullets. Just download the profile. Extract the zip into your ViPER4Android directory in your storage location. Now Load the profile in Viper and you are good to go.
You can download it from here

V4A FX is the right one.
Btw thanks OP, your profile works great

This is exactly what I was looking for. We loose volume but they don't feel flat anymore. I don't have any other good earphones and was wondering if this Does makes the bullets better sounding than other options like the air pods ?

man if someone come up with a profile for the Momentum True Wireless I'd give him gold. Loving those

If anyone is wondering this profile works on bullets wireless 2 aswell, make sure you install V4A FX Legacy from magisk and load effects profile also check convolver. Thanks a ton OP. Also if anyone has a link to a profile specifically built for BW2 please please PM me or link it here.

Hello,
i cant get this to work on Viper4Android v2.7.1.0 (which is latest i guess) on Android 10. Using Oneplus 6 Havoc OS latest Version default kernel.
I already tried to rename the "Profile" Folder into "Preset", which doesnt work. (I think Profile got renamed into Preset)
Maybe anyone has an idea how to get this to work? Or maybe someone has screenshots, how to build this without loading the profile?
i would be pleased about an answer and thank you very much for the work!

Open viper4android, click on bluetooth output, activate, activate convolver, expand convolver list entry, click on "impulse response" and pick the IRS file from the ZIP

Upon installing through Magisk I used the up volume on every option. Open the app, start playing music. Toggle master switch off then back on. Start making your adjustments. Save profile. Sometimes you may have to exit viper4android from inside the app then re-open, to get it working.

I'm on 4.3. and I noticed playback gain control seems to have no effect. I suspect it's because of the intrinsic Dolby Atmos drivers already natively on our device. have you discovered a way to get it to work correctly? viper has no punch like it used to have on my op6

On both Bluetooth earphones, playback gain has no effect. However it does increase volume in Jeep Bluetooth audio. The thing with the earphones though it doesn't need any gain. Normal listening volume say at the gym, is 2 steps from mute. Around quarter way to half volume it is extremely loud. I also disable absolute volume in developer options. So the wireless bullets volume is separate from the media volume. You really need to check out each toggle and adjust to your liking. Install some convolver files they really make a difference.
