sorry for my mistake..
i have reported the thread..hope it will be moved soon.

Hi ! what's the difference between the two versions ? Which seems to be working better for you ?

Xhifi is for audio clarity and fx is for bass and sound effect enhancement.
Also I flashed it and heard the music for whole week but it is not better than acid audio with noozoxide.

So i am using Viper4Android right now, it has so many settings that finding *that* effect might need a bit of trial and error.. here is something that works for me, Keep in mind that this is basically moderately Bass enhanced for Dub/Chillstep probably House/Electro Music...basically Club music xD
Changes in FX ->
Powered On
Playback Gain Control Disabled (enabled this option in HiFX and disabled it here)
Firequalizer disabled (using this equalizer in HiFX)
Convolver -> Get the pack and using SPL GoldMIKE Impulse.IRS
Then nothing changed till,
Dynamic System -> Common Earphone(v2) Dynamic Bass (3 Percent)
Cure Tech+ ENABlED (Slight)
Gain -> up to you (6db already enabled for me via STweaks so i didn't use any here)
------
Changes in HiFX->
Powered ON (Of course)
Playback Gain Control -> Slight Enabled. Disabled in FX
Audio Reconstruct Enabled -> HiClarity 70 ; Lo Contour 45 (up to your preference really )
and the Equalizer totally up to you, I use a S shape like seen in the attached picture
As for hardware, Im using the stock Samsung headphones with the smallest earbuds (lost the medium sized ones, which gave better bass output, thus you might have to tweak this a little bit for your phone..)

This improve the sound but eats battery faster than playing nfs most wanted with max brightness wifi and bluetooth on

Special PowerAmp PureX+ Presets:
PureXPsychoRealism+ - Just like PureXPsychoRealism; this preset enhances bass effectively (Increased 30Hz - 60Hz bands), enhances treble by increasing 16k band and 8k whilst keeping clarity by reducing 500k, 1k and 2k bands. This is a more precise version of normal PureXPsychoRealism.
General Audio Effects (Equalizer presets only in Sound Enhancements):
PureXPsychoRealism - Experience realistic audio, rich deep bass and realistic acoustics. Best acoustics and bass you will ever hear. (This is best used on Headphones)
PureXHiClarity - Listen to Clarity like never before, from Ultra high frequencies to crystal clear vocals. This is clarity at it's best. (This is best used on earphones)
PureXBeats - Optimized and fine-tuned for Beats by Dr Dre headphones/earphones. Get rid of that terrible 'muddy' sound beats headphones/earphones produce by too much bass, hear more clarity in your Beats headphones/earphones.
Common Effects:
PureXDynamics is a more effective way to minimize volume differences (Like the Dynamic Normalizer) Acts like a audio limiter, it's a more safer way to listen to audio as it softens the other instrument volumes down so that every instrument can still be heard.
Speaker Effects (System-Wide when enabled):
PureXIntenseBLAST - Greatly enhance audio volume of internal speaker (Modded version of xLOUD)
PureXHiFi - Greatly enhance audio quality of internal speaker (Modded version of ClearPhase)
Don't be fooled by your Settings saying ClearPhase and xLOUD in sound settings still, they are just the names, they will still produce the exact same effect as the two above but it is renamed in Walkman Sound Enhancements however
If you are using the phone in a different language OTHER than English, please note that User-Defined 1 is PureXPsychoRealism, User-Defined 2 is PureXHiClarity and Custom is PureXBeats
These effects can all be enabled through Sony Walkman Sound Enhancements.

NOTE: DO NOT INCLUDE ANY OF THE MODS IN THIS THREAD IN ROMS WITHOUT MY PERMISSION! I WILL ONLY ASK ONCE, IT IS MANDATORY THAT YOU PM ME OR NOTIFY ME BEFORE YOU PUT THIS IN YOUR ROM OR OPEN ANOTHER THREAD SOMEWHERE ELSE ON XDA,LAST WARNING. ANY THREADS OPENED WITHOUT LETTING ME KNOW WILL BE REPORTED IMMEDIATELY!
NOTE 2: It SHOULD work with all Xperia Firmware-Based ROMs, not so sure about AOSP roms as I have a lock bootloader and therefore I cannot try them out. Please do not constantly ask if it will work for a specific rom, Try before you ask.
NOTE 3: PLEASE! FOR YOUR OWN SAFTEY, MAKE A NAND BACKUP FOR YOUR ROM! I WILL NOT BE GIVING INSTRUCTIONS TO UNINSTALL.
NOTE 4: This mod will work for Locked/Unlocked Bootloaders as long as you have a custom recovery.
NOTE 5: The speaker's audio quality becomes worse as you increase volume, this is because our speaker cannot output good audio quality at loud volumes.It is impossible to keep audio quality and loud volume because of out hardware. The HTC One has a dedicated Amp inside it's chipset which amplifies audio better with more sound, that is why new HTC phones can have very loud speaker volume with good speaker audio quality.
NOTE 6: Sometimes, if you play music, it could take a few seconds to let Sound Enhancements load your settings (This is normal)
NOTE 7: If you are on another device and is using Xperia Z version (The updated version of this soundmod and not PureXAudioLITE) Don't be mistaken that all features work, because it just won't. My audio mod is specifically made for the APQ8064 chipset and WCD9310 DAC (MPQ8064 audio too) the features will not ALL work because every device has different hardware/software, even if it install fine, not all features will work. Don't get confused.
NOTE 8: I advise everyone to go onto XZDualRecovery as it's the only recovery (As I am aware of) which has native init.d installed directly in it's ramdisk just so you can use the init.d scripts in my mod. (Only applies to locked bootloaders)
NOTE 9: If you are having audio skipping issues, make sure that you exclude: Walkman (If you have 2 Walkman apps, select the second one), PureXAudio Engine and MusicFX in STAMINA Mode so that the phone will not try and make it inactive. If you have Skipping in any other music player, add that in the exclude list of Stamina mode.
NOTE 10: Hearing impairment is caused by volumes higher then 85dB as stated in Wiki "If one is exposed to loud sound (including music) at high levels or for extended durations (85 dB A or greater), then hearing impairment will occur." If you feel uncomfortable when hearing music, I strongly advise you to either turn down the volume or have a rest.

Sent from my C6902 using XDA Premium 4 mobile app

Downloaded and flashed it ...but..
Sound enhancements are not working, when in settings under sound sound enhancements dont open at all
In walkman mode sound enhancements also dont open
Plus, it says in the OP that the overall sound coming out of the internal speaker has been increased but again, I did not feel any difference at all, please make this happen since as always internal speaker of the Z1 also is very weak therefore please, increased sound from the internal speaker for ringtones and notifications and increase sound from the in-call speaker greatly will be really nice...
Also, upload the stock sound file in CWM flashable format as well so if anyone wants to go back to stock...I know backup restore from TB should haven been done or backuy CWM or TWRP but I did not do any of those ... CWM & TWRP will reboot after 40 seconds so no use in making a backup for now, plus since my 64GB card is on its way I have not made any TB backups now.. So having a stock sound .zip file will help very much to me and to some other users also...
Hopefully these issues will be solved in the next update..cant wait...

As with all these mods there should be a health warning in the OP that the only way to go back to stock is via a nandroid backup or a clean reinstall of the rom. These sound mods change so many files its next to impossible to manually go back yourself with out a backup.
I know this does not help you, but I hope others will read this and take the backup.

I guess this is the only way for now until Doomlord fixes the 40 seconds reboot in recovery ... once thats fixed then only we all will be able to perform Nandroid Backup...

i am not making any apps tweaking yet
i need to bring Zero's presets into Walkman somehow
but for that we gotta be deodexing the whole ROM

Now we should have Walkman working as it should

Just installed the V2
Used TWRP to flash first
- After booting, in settings the sound effects are still not responding, meaning I when click on sound effects nothing happens
- In walkman, in settings the sound effects are also not responding
- In google music player, when I click on settings and goto sound effects it opens, but when I goto EQ settings and select any new EQ the EQ sliders does not move at all they all remain at Zero which is right in the middle.
Used CWM to flash and same thing as above for settings, walkman, google music player.
So V2 is not working for me either...

TIP #1:
If your G2 stock earbuds fit your ear canals really well, see if they fit on your other earphones!
I tried these G2 ear buds on my ie-80 in-ears and i can honestly say they give the best seal i have had in 7 months since getting these earphones!
The G2 buds have an abnormally large hole diameter which allows alot more high/mid range through than my previous sets. Stoked!
TIP #2:
Clean your in-ear headphones regularly, scotch tape works great!
Pull off the earbuds and carefully dab (do not rub) each the earphone housing speaker grills repeatedly with sticky part of the scotch tape to remove any wax/dirt buildup.
Repeat this once every 1 - 2 weeks to ensure longer life/good sound of your earphones.
If possible store your in-ears in a clean container/sealed carry pouch so they do not collect dust/lint/dirt from your pockets.

Thanks for the mod. Tested a FLAC song with stock music player on speakers. Max volume and no distortion.

Great to hear!
On a note of personal note, i had viper4android installed on my LG G2 but with these modifications,
i ended up uninstalling it as i was primarily using it for volume boost purposes as opposed to signal shaping/eq-ing.
I also found that viper4android would work randomly with some files but not others.
IMO Volume boosting should work consistently at all times, across the board.
From the purist/consistency train of thought this volume mod will give you consistent volume boosting and more power to your headphones (fuller sound) without altering/degrading the already superb audio signal, or adding digital noise.
That being said, viper4android is a great app for shaping the sound signature, which is what it is primarily designed for.
For me, "the closer to the original source, the better"

Much improved sound. Thanks.

This is an external Speaker and Headphone Volume level modification.
It is what I feel "should have been" the stock "happy medium" audio levels for the LG G2.
The DAC audio quality coming from the LG G2 is excellent.
This modification brings the listening sweet spot down to 50% volume level instead of the 80-90% volume range at stock.
Stock levels did not push test headphones as well.
Benefits:
- Removes the need for 3rd party audio VOLUME BOOST apps
- Does not alter DAC raw audio signal quality
- Provides optimized signal drive for higher ohm headphones
- Improved audio fullness
- Improved low end at optimal listening levels
This MOD works with:
All LG G2 Carriers
This Mod Affects:

Instructions:
On your phone:
1. Use Root Browser (or similar File Explorer) to navigate to: /system/etc/snd_soc_msm
2. Locate the file called: "snd_soc_msm_Taiko"
3. Copy this file to your storage as a backup in case you decide to revert back to stock.
4. Download the "snd_soc_msm_Taiko" file to your phone: http://www44.zippyshare.com/v/67179492/file.html
5. Once complete, paste the downloaded "snd_soc_msm_Taiko" file into: /system/etc/snd_soc_msm
Choose yes to overwrite the existing file.
6. Restart your phone, and test external speaker and headphones with starting with volume at 0%
7. If this improved your G2 audio, say thanks, and enjoy your music!

Permissions should not make a difference in this case, however you can set them to rw~r~~r~~ for the file as shook mentioned using root explorer.
Mine are currently set to rw~rw~r~~ and there is no difference in performance.

Really.
Well not giving thanks where its due, is even more lame, not to mention it is Thanksgiving today after all..
1. For what its worth i stumbled on this file in my G2 looking through sys etc files as a result of modding my note 2 last year in similar fashion, when i was looking for volume boosting without 3rd party apps at the time.
2. I have spent time testing to ensure i get the levels right on a fair range of equipment, and i feel others should be entitled the chance to benefit from this as well.
3. That thread that i ended up finding (and linking out of courtesy regardless) is pretty convoluted and a bit of a mess, labelled ATT (i am on Bell and this is a universal fix, not just ATT), and realistically only addresses speaker volume.
4. I have provided a working tested version of the file that G2 owners can use if they choose; not everyone is comfortable/has time/patience to edit/test settings in order to enjoy the untapped potential their phones have to offer.
5. I was in actuality not soliciting (seeing as we are NOT selling anything here), but making a factual observation through my thanks post, and the same applies to all positive dev/mod work.
You're welcome.

thanks, audio seems improved and much higher.
maybe a bit too high.. I can't set volume up to middle.

" This is for the mod in android development.. I cant post anything there cause im a new memeber so i need ten posts...
Bassically if you do this mod it will make speaker mode not work... You can hear the other person but they wont hear you.. It disables the mic... Same thing if u use earphones with a mic... U could hear them but they wont hear you....

The version i posted on this thread works fine with no issues.
I have tested the scenarios detailed in your post using 2 different cell phone lines, calling my g2 from another cell, and vice versa.
Both with speaker mode enabled/disabled, and with/without headphones.
Mic works fine in both cases for me, no issues here on my Bell version G2.
I do not currently have a pair of headphones with microphone built in to test that format though, if anyone else can test that would be great.
Please clarify carrier, whether phone is stock or not,whether has he done any file edits after the fact, etc.

Please confirm headphone model you are using if possible.

Permissions should not make a difference in this case, however you can set them to rw~r~~r~~ for the file as shook mentioned using root explorer.
Mine are currently set to rw~rw~r~~ and there is no difference in performance.
I have updated with step 6 as optional. Cheers!

|AUDIO MOD|MiMAX|04-07|DAC HAX|DUALSPEAKERS|AROMA|HIFI AUDIO|shox AUDIO MOD v2.3|

Hey guys...
ScreaMySkrillEX here.
This is an audio mod made for the redmi note 3(kenzo/Kate) which also works on mi max(hydrogen/helium) as both the devices share the same audio codec and streams.
What does my mod do?
It enables dual speaker config on your device and has two variants(htc10/stereo). And there's also a stock version which only tweaks the headphone audio output.
Htc10 version uses both earpiece and loudspeaker for audio output. The output is mono and hence earpiece acts like a mid-range booster and adds more detail to the speaker audio.
Stereo version also uses both speakers for audio output but earpiece behaves as left speaker and loudspeaker behaves as the right speaker.
Instructions.
1) Download the latest zip from the drive folder link below:
https://drive.google.com/folderview?id=0B5ratNhH-7mGU3AtTVFmekE4VG8
2)Reboot to recovery.
3)Flash shox Audio Mod zip.(while flashing the file shows that its made for kenzo/Kate. Don't worry, it will work for your device also xD)
4)Reboot.
5)Feel the shox effect!
Enjoy the music...
If you have any requests or problems, feel free to ask.
I will definitely help you.
And you guys are most welcome for your suggestions.
Read the 2nd post for more info and recommended tips.
Thanks to:
@chdloc - For his biquads app and support. He has thought me many things. A brilliant dev.
@UltraM8 - For his Ainur Sauron audio mod.
@zhuhang - For his viper4android app and IRS samples.
@Albertkuba - For actually informing that this mod works for mi max too. This thread is because of him
@ZeroInfinity - He is the inspiration for me. His works are really brilliant.

Recommended tips:
1)Flash Ainur Sauron audio mod made by @UltraM8 along with this mod for a much better experience.This is currently the best audio mod which is the cleanest..Please thank him for his great work...
Link here: https://forum.xda-developers.com/android/software/soundmod-ainur-audio-t3450516
2)Users who need more tweaking to the audio can use Viper4Android.
3)I have included some of the best IRS samples for viper4android(according to me). So try it out if you are using viper4android for complete control over your music. Extract the zip and place the contents in viper4android/kernel directory of your internal storage.(the zip provided is not recovery flashable).
4)People who use MX player for videos can enable SW audio boost which will further increase the sound levels through speakers without any distortions..
It is recommended not to listen through speakers at full volume for longer periods.. Keep the volume low by 1 or 2 steps from the max.
5)People who think that the present max volume through headphones isn't enough can install viper4android and increase output gain to 6dB in master gate..
My personal Viper4Android settings:
Master power - on
Playback gain control - off
FET compressor - off
Viper DDC - on, set to sennheiser hd558
Spectrum extension - on, set to 1.0
Firequalizer - off
Convolver - off
Differential surround, field surround, headphone surround+, reverberation - all set to off
Dynamic system - off
Viper bass - off
Viper clarity - off
Tube sound simulator - off
AnalogX - on, set to extreme
My earphones :
1) Sennheiser cx180 street-II - daily outdoor use.
2) Skullcandy Ink'D - used rarely.
3) Sony MDR-ED12LP - used when I'm at home.
List of smartphones I own right now:
1) Xiaomi Redmi Note 3(kenzo)
2) Samsung Galaxy S(i9000)
3) Xiaomi Redmi Note 4(Mido)
4) Samsung Galaxy Note(n7000)
CHANGELOGS:-
V1 - initial release.
V1.1 - tweaked the values a bit to further remove the hissing noise as reported by @MurdererFight.(thanks bro for being the first tester and reporting me)
V1.2 - added some tweaks which will truly enable HiFi audio through DAC with the help of a magisk module..now the DAC detects the impedance of the earphone or the headphone connected.this ensures proper voltage levels through the amp for the earphones/headphones.
V1.3 - Merged surround audio mod along with hifi audio..
Enjoy stereo-like sound on your kenzo (earpiece speaker also outputs sound now xD, videos feel more alive to watch now).Thanks to @AgentBuBu for the soundmod.
I just merged his mod with mine..
V1.4 - Changed the earpiece thresholds to remove the crackling sound and readjusted both the speaker sound to the same level. Now enjoy stereo like never before on your kenzo's speakers. Thanks to @Androbots for reporting this.Also made the mod universal by making a magisk and SuperSU version..
V1.45 - Readjusted the values again for both earpiece and loudspeaker to remove distortion completely, increased audio volume through headphone jack without disturbing the quality. So, now there's a very little drop in the audio but the quality is absolute eargasm.
v1.5 - Readjusted and increased the volume of both earpiece and speaker without inducing distortions. The sound level is more than stock now.
And further pushed the volume through headphones for louder volume..Now the stereo feel is amazing..
And included biQuads support for headphones for expert users. Now you can correct the frequency response of your beloved cans, IEMs.
Link for biQuads is here:
https://forum.xda-developers.com/showpost.php?p=70194192&postcount=226
v1.6 - This time made sure to keep the audio levels same at the earpiece and loudspeaker to increase the stereo and ambience.
Very little changes to headphone volume again. Removed some unused codes. Its true stereo now. Enjoy the stereo on speakers like never before
v1.7 - Fixed the messed up headphone gain as reported by @AravindhStanley and now has 2 new versions...
1) Stereo Version - The present version which you guys are using..earpiece acts as the left speaker and loudspeaker acts as the right speaker. The speaker volume and earpiece volume is balanced
2) HTC 10 Version - The new one!!!! it is based on the new HTC 10 loudspeaker audio output.. Its mono but still uses earpiece for sound. But here the earpiece acts as a mid range and bass booster and significantly increases the detail of sound heard through speakers. Here, the loudspeaker is louder than the earpiece. The earpiece just adds detail here. So don't complain about unbalanced audio levels as its kept unbalanced.
This version removes all the audio libs to disable audio offloading to the dsp..Now the audio goes straight to the DAC untouched..
So please flash your audio mods once again after flashing the mod to get them back working.
Now biQuads is fixed by the founder @chdloc himself..So its finally working now....
I recommend all the users to try both the version and keep the ones which you like.
The link to new biQuads is here:
https://forum.xda-developers.com/showpost.php?p=70194192&postcount=226
v1.7fix - This is only for HTC 10 version...Many users would have experienced no audio from the loudspeaker after flashing v1.7(it wasn't intended to work like that). This issue has been fixed. Now enjoy audio on both earpiece and loudspeaker. Loudspeaker has louder volume than earpiece as earpiece just acts like a mid range and bass booster like before.. Enjoy the sound now..
v1.8 - Made significant changes to headphone audio....
Now the audio is decoded at 24bit 192khz..but still the output is 16bit 48khz..wait for the Poweramp to fix it or if anyone knows how to edit audioflinger please pm me...if audioflinger is hacked, 24bit 192khz audio can be made systemwide....
And enabled hardware Dolby and DTS-HPX support...
Use any of the sound mod which has support for them...you will feel a difference..
Nothing much changed in speaker audio..
Reflash your audio mods again....dirty flash
v1.9 - Rebased with the stock mixer_paths.XML and edited it from the start again..its much clean and removed useless codes from the file..
Fixed the bug - in-call voice through speakers even though the phone was in earpiece mode as reported by @AravindhStanley
Finally the mod is universal! One flashable zip for all ROMs and kernels so no hustle of magisk or su versions.
Dropped the HTC10 version as I dint see much potential in it..It will be continued only on demand..
Temporarily removed biQuads support as it requires an in-depth inspection..will include it in the next build..
V2.0 - *Fixed low audio volume on headphones as reported by many....
*Introducing a stock version, which only tweaks the headphone audio leaving the speakers untouched(stock config)
*Reincarnated the HTC10 version as requested by @mahmoudthassan
V2.1 - *added bass filter for earpiece in both htc10 and stereo version to protect the speaker..
*added a bass filter for headphones also to improve bass range which also reduces distortion..
*created an uninstaller for the mod..
V2.2 - *renamed the mod from HI-FI AUDIO PATCH to shox Audio Mod.
*finally implemented biQuads and added my sound signature to the headphone audio output.
*increased the amp volume to 16 to increase output volume.
*included patched kernels also for the mod as it is mandatory.

This is a guide for creating your own biQuads which replaces the existing ones in the mod.
As you all know, biQuads is a set of 5 IIR filters which can be used to enhance the music and also correct the frequency response of the headphones/earphones which you use.
Continue from here only if you know what sampling rate, bit width, lowpass, highpass, peak filters mean. Otherwise google those terms and learn what they are and what they do
So here's how to design your own biQuads and listen the music in your way:
1) Download biQuads flashable zip from the XDA thread here:
https://forum.xda-developers.com/android/software/reference-qualcomm-audio-codec-iir-t3093000
Thank @chdloc for this great work.
2) Flash the zip in recovery and reboot.
3) You will see an app named biQuads in the apps drawer.
4) Open the app and give it root access.
5)As I told earlier, there are biQuads numbering from 1 to 5
6)After every filter you create for every number, tap design biQuad and wait for 20-30sec. You will be redirected to another window where the app check whether the filter is designed correctly or not with a spectrum graph. After that, increase the biQuad number
7) Do the same step 6 again and again from 1 to 5 until your biQuads is ready.
8)Finally, select review filter where you get a final graph and parameters of different IIR filters.
9)Then select save and give your biQuads a name(make sure there are no spaces included in the name). Click accept and the file gets saved in the internal sdcard with the filename you specified.
10)Open the *.coeffs where * is the name you specified for the biQuads in a text editor.
11) Replace IIR2 with IIR0 wherever found and change INP1 to INP2 wherever found.
12) Finally copy everything from the file and replace the contents in the mixer paths(present in /system/etc) under path name headphones. You will find similar lines there which are my biQuads already implemented.(make sure that you file editor has root access)
13) Replace those lines perfectly and align the lines as they were. Save the file when you are done and reboot.
14) Magic.

Thanks. I've been waiting for a dual speakers mod for a long time.
HTC 10 mod version makes the sound output like it's coming out of a can. But the stereo mod is great.

ERR_CONNECTION_REFUSED
Edit: weird, the problem was only accessing from my Mi Max.
Thanks, i'm gonna to try your mod.

Is there a way to make the earpiece speaker louder that default? On the Mi Max, mine at least, it's far quieter than the main speaker, meaning it, doesn't seem like it does much.
This also means that in Stereo mode, the left channel is far more underpowered when stereo content is playing, and it's noticeable.

Maybe htc10 version is more suitable for this device..
If you have a kernel with sound control, try increasing microphone volume.

Was the same with the HTC10 version, and I'm not sure if I have a kernel that can do that, and even if I did, how would I go about doing that?

Discovered a bug with this mod. Installing this would disable mic thus any video you record has no audio. Worse uninstalling this mod would not remove the bug. So I had to reflash ROM.

Nope, as far as the speaker doesn't distort

????????

hello and kudos for this feat.
but forgive me for asking a stupid question, will this work with bluetooth stereo headphones?
-------
UPDATE
tried it... worked! muchos gracias!

Working but it have a bugs which video recording has no sound and it also break Hi-Res audio playback on PowerAmp alpha build 704. IEM/Headphone left channel volume sometime really quiet while right channel was too loud. I have to unplug and replug audio jack to make both channels working again.
Tested with Mi Max hydrogen 6.0.1 + Audio Technica ATH-IM50/ATH-M40X/Trinity Delta
For anyone who suffer same bugs, replace mixer_paths_wcd9326.xml and mixer_paths.xml in /system/etc and set permission to 0644

thanks for the heads up.
mine is hydrogen on GlobeROM 7.7.20 + Viper4Arise
did not loose audio on video recording.

Viper4Arise is only used to further tweak the settings that this MOD offers.
so i think its just but OK not to install Viper.
also, if you already have a 3rd-party recovery, you can easily flash this.

Can it be used with viperfx?

Yes. But for max audio quality i use JamesDSP magisk. JamesDSP supports 48000Hz 24bit PCM meanwhile ViperFX or Viper4Android supports 48000Hz 16bit PCM.

how to apply it?

Hello guys, sorry for the late reply.
I was very busy during my final year degree. Here is the latest version. I only make the audio correction file in .wav format because .wav is superior than .vdc in my testing. This is the most flattest sound signature I can produce right now. 48KHz 32bit.
Mirror link:
Pixel 4_4XL Speaker.wav
drive.google.com
You need to install JamesDSP magisk module. Viper4Android also can but JamesDSP has better audio processing.
To apply this mod, copy the .wav folder inside JamesDSP/convolver. Then, you open the JamesDSP app and load the .wav file (See screenshot)
