ViPER4Android FX (V4A) Audio Effects

Found this on this thread below and I have to say after trying every music mod out there that this is one step ahead of everybody else. Check it out here. I have been listening to it for half a day now and it's amazing. It has so many sound options that it takes awhile to figure them out. But if you are a music freak like me once you listen to it you will say it's definitely worth the time to figure it all out. After checking the thread out if anybody is confused about how to install the apk's and files I will explain it the easiest way can for you. Thanks and enjoy!!!

Default F.A.Q - Frequently Asked Questions (Up to date)
--------------------------------------------------------------------------------
Updated 5/8/2013
Since Android 4.1, Google started to close down Android whole system audio effect.
"The main reason is there's many problem we can't fix, therefore we can only apologize to audio effect developers. In future, it will be fixed and whole system audio effect will be back." - GOOGLE
Therefore in certain players certain roms, V4A will not work.
- Will it work on my device?
A: V4A works on almost every ROOTED android devices. Refer requirements in OP.
- How to install?
A: Using the In-App installation, make sure you have busybox installed, first-run the app and follow through the installation dialogues.
- Which to install? FX or XHiFi or Both?
A: FX has many audio effects, where as XHiFi restores audio quality. If you like many effects(reverb, bass, surround) then choose FX, if you like clear audio/vocal and you have a good headset, choose XHiFi. You can also install both, more CPU usage, that's all.
- Why ViPER4Android FX/XHiFi always FC?
A: Uninstall and Reinstall V4A using NEW In-App Installation. This is due to driver not installed properly.
- Why ViPER4Android FX/XHiFi creates unexpected effects and different from other users?
A: Clear ViPER4Android FX/XHiFi data. If persist, disable third-party sound mods such as Noozxoide, Bass Booster etc)
- Third-party players such as Poweramp and TTPOD no effect?
A: Open V4A app and switch to FX Compatible Mode. (Driver status will show processing=No, but its working.)
- ViPER4Android FX/XHiFi doesnt run after bootup?
A: Check anti-virus or startup manager app whether V4A was disabled in startup list.
- V4A FX/XHiFi effect gone after using data-killer?
A: Please add ViPER4Android FX/XHiFi to data-killer app white list or exception.
- V4A FX/XHiFi effects suddenly disappeared?
A: Android system kills certain processes due to memory limits. Install V4A app as system app (Put in /system/app/ and restart)
- Why there is background noise when using V4A effects?
A: This is Android's musicFX bug, this will happen on all other sound mods.
Suggestion: Backup and Delete /system/lib/soundfx/libbundlewrapper.so
- V4A XHiFi effects gone after reaching certain volume? (~70%)
A: This is due to Sony Xperia hearing protection library. Backup and Delete /system/lib/soundfx/libhearingprotection.so
- How to use FIR-Equalizer?
A: See "How to use FIR-Equalizer" guide in XDA Original post.
- Why there's no change in sound quality after installing V4A?
A1: Choose V4A in Sound Settings > Music Effects. (Driver status will show processing=Yes)
A2: Open V4A app and switch to FX Compatible Mode. (Driver status will show processing=No, but its working.)
- Why volume reduces after 10 seconds?
A: This is not caused by V4A. Most probably you installed a bad and faulty xLOUD, ClearPhase or S-Force Front Surround port.
- Why music spoilt after display off?
A: This is due to CPU speed too low when screen if off. Make sure you are not using some battery saving CPU governor (such as smartass) or created own CPU profile.
Switch CPU governor to ondemand or interactive, to increase CPU speed.
- Can I still install V4A if I already using other sound mods?
A: Yes, after installation, open V4A app and switch to FX Compatible Mode.
- Why phone auto-reboot after I plugin headset? Normally for HTC phones.
A: Uninstall and Reinstall V4A using NEW In-App Installation.
- In-call volume reduced?
A: Uninstall and Reinstall V4A using NEW In-App Installation. If persist, its caused by other sound mod because V4A will not affect call volume.
- What if my phone/tablet cannot detect headset plugin?
A: In ViPER4Android app press menu, choose lock effect mode and choose headset, then adjust settings.
- I dont know my phone is which CPU type?
A:
Qualcomm CPU, freq higher than 800MHz, choose ARMV5TE, freq higher than 800MHz(including dual/quad core)choose A8.
Samsung CPU, single core choose A8, dual/quad core choose A9.
Huawei HiSilicon CPU, single-core choose A8, dual/quad core choose A9.
Other CPU, single-core choose A8, dual/quad core choose A9.
- Driver status shows version 0.0.0.0 even after rebooting?
A: Due to wrong driver used, try lower level drivers. Eg: A9 change to A8; A8 change to Tegra2.
- Driver status shows "Enabled: No, Processing: No", but i already turn on effects and playing music?
A：In FX Compatible Mode, driver status will always show No, but its working.
In Normal Mode, its due to reason at the starting of this post.
- Why no effect in MIUI player?
A: Open V4A app and switch to FX Compatible Mode. or Turn off MIUI default equalizer.
- Im using Meizu, Flyme system, why effect gone after i display lyrics?
A: Flyme modified Android's Audio principle, so lyrics will be treated as music effect by the music player, so V4A cant be used.
- V4A effects will spoil internal speaker/headset?
A: Firstly, there's an audiophile limit in your phone, even if you max every single settings in V4A, u will never achive that limit.
If the limit is achieved, your ears will blown off before the headset.
If your earphone is not used to high volume/bass, with long period of high volume/bass will cause your headset to spoil (without V4A it will also spoil)
For speaker, if a new phone straight away max the volume, within few days there will be distortion. Start off with 50~70% volume and after some time only max the volume.
About compatibility problem:
With the NEW In-App Installation, V4A will be installed into your system without problem. All system-provided sound effects will not be removed or overwritten.
V4A Audio E
Default FX & XHiFi Settings Explained & Recommended Value
--------------------------------------------------------------------------------
The latest version: FX v2.2.0.7, XHiFi v2.1.0.0
[FX Settings]
V4A FX version mainly for rendering audio effects, by controlling various parameters to achieve the purpose of audio effect adjustment.
1. Master Power. This option defines whether to enable V4A headset sound effects, also known as main switch.
2. Playback Gain Control. It is mainly used to dynamically control the audio volume, to amplify or to attenuate.
(1) Enable checkbox. Whether the effect is enabled.
(2) Select Effect Strength. Effect Strength is the speed of amplification or attenuation, the stronger the faster the speed and the higher the final volume, the weaker the slower the speed, the closer to the original volume. Recommended medium.
(3) Max Gain. When the volume of the note is too small, in order to uplevel the sound, there may be very large magnification. The higher the value, the louder the volume. But too large will also amplify the noise within the song. Recommended 4 times.
(4) Max Output. This value defines the maximum volume of the PlaybackAGC sound in decibel value, the greater the value the greater the volume, 0 db is the maximum. In order to make the sound softer recommended -1.9 dB.
3. FIR Equalizer. 511-order 10 bands FIR linear equalizer.
(1) Enable checkbox. Whether the effect is enabled.
(2) Select Preset. Here you can select default equalizer presets. When choosing custom, it will follow the user-defined lines drawn.
(3) Linear Equalizer graphic. Will pop up when you touch the graphic equalizer, you can manually adjust the levels of amplification and attenuation of the 10 bands.
4. Convolver
When an impulse response(IR) sample is loaded, music will show the same characteristics of the loaded sample, for example equalizer, surround, reverberation, tube etc.
Make sure SD Card has /ViPER4Android/Kernel/ folder, IR samples will be located there. If folder not exists, you can download latest V4A FX and extract SDCard_V4A.zip.
(1) Enable checkbox. Whether the effect is enabled.
(2) Impulse Response. Here you can select and load IR Samples inside /ViPER4Android/Kernel/ folder.
5. Field Surround. It is mainly used to create sound field surround effects. The sound field can be understood as mono field or stereo field.
(1) Enable checkbox. Whether the effect is enabled.
(2) Select Field Surround Strength. This value defines the strength of the field surround effects. The stronger, the stereo effect will be more obvious, the sound will come from left and right sides. Recommended medium.
(3) Select Mid Image Strength. This value defines the central vocal intensity. More strongman sound more clear, the weaker the more ethereal sound.
6. Reverberation. It uses mathematical methods to simulate the environmental feeling sensation. Example a song can be felt playing inside the auditorium, living room, bathroom, and so on.
(1) Enable checkbox. Whether the effect is enabled.
(2) Room Size. This value defines the virtual environment area size. The larger the value, the sound is wider and more echoes.
(3) Sound Field. This value defines the width of the room above, in meters. Assumed that the above room size is 100 square meters, here to set a width of 14 meters, then the length of the room will be 7.14 m.
Therefore, the room size and width defines the aspect ratio of the virtual environment.
The larger the value, the sound coming from both sides will felt more obvious.
(4) Damping Factor. This value defines the humidity of air in the above virtual environment, the moisture vapor in the air will easily absorb the echoes.
So the bigger this value, the less echoes heard.
(5) Wet Signal. This value defines the volume of the simulated environment effect.
(6) Dry Signal. This value defines the volume of the original sound.
For environments with low air humidity such as living room, auditorium and other indoor environment, you can use room size and sound field to define the area of ​​the virtual environment, water vapor content values ​​from 0 to 20, the reverb signal values ​​20 to 50, the proportion of the original signal to take value of about 50.
For environments with high air humidity such as bathroom and other indoor environment that contains a lot of moisture, you can use room size and sound field to define the area of ​​the virtual environment, water vapor content values ​​of 50 to 100, the reverb signal values ​​40 to 80, the proportion of the original signal value of about 50.
7. Dynamic System. It handles the dynamic range of the sound. In other words the bass, treble, and limiting.
(1) Enable checkbox. Whether the effect is enabled.
(2) Select Listening Device. This value defines the headset type connected to the audio jack. If you cannot get the right device for good bass tone, then select Common earphone. Common earphone is a common choice. Recommend Common earphone.
(3) Select Dynamic Bass. This value defines the average dynamic bass, the greater the stronger bass. Recommend 33%.
(4) Tube Simulator(6N1J). This option defines whether to enable tube simulator effect. V4A tube simulator uses a simplified mathematical simulation of tube effect.
If turned on, will greatly reduce high-frequency odd harmonic distortions, while increases even-order harmonic distortions of tube simulator.
8. Master Gate(Limiter). This option is V4A output limiter, its used to prevent overloud clipping distortion.
(1) Ouput Gain. This value defines the main output volume. Its something like a volume control.
(2) Limit Threshold. This value defines the limits of waveform amplitude by the limitor, 0 dB is the maximum value.
The smaller the value, the easier to experience audio frequency compression(the smaller the volume), will lose sound details, but can effectively control the final output volume. Recommend 0 db.
1. Master Power. This option defines whether to enable V4A speaker sound effects, also known as main switch
2. FIR Equalizer. Same as headset equalizer.
3. Convolver. Same as headset convolver.
4. Reverberation. Same as headset reverberation
5. Extra Loud. eXtra-Loud further amplifies the sound, but is controlled to protect the speaker, will not overload.
(1) Enable checkbox. Whether the effect is enabled.
(2) Select Effect Strength. Effect Strength is the speed of amplification or attenuation, the stronger the faster the speed and the higher the final volume, the weaker the slower the speed, the closer to the original volume. Recommended medium.
(3) Max Gain. When the volume of the note is too small, in order to uplevel the sound, there may be very large magnification. The higher the value, the louder the volume. Recommend infinity.
(4) Max Output. This value defines the maximum volume of the EL sound in decibel value, the greater the value the greater the volume, 0 db is the maximum. Recommend 0db.
6. Master Gate(Limiter). Same as headset limiter.
V4A XHiFi version mainly for restoring audio quality and details.
1. Master Power. This option defines whether to enable V4A headset/bluetooth sound effects, also known as main switch.
2. Playback Gain Control. Same as FX version's PlaybackAGC.
3. FIR Equalizer. 2047-order 10 bands, quality much better than FX version. Method of adjusting same as FX version.
4. Audio Reconstruction. It is XHiFi's core feature, it does the detailing and treble restoring for lossy mp3 audio files. (Currently in adjustment phase, different device may have different experience.)
(1) Enable checkbox. Whether the effect is enabled.
(2) Hi Clarity. This value defines the detailing and treble restoration percentage, the larger the value, the more details of the sound and stronger treble.
For low-end/common earphones, this is not recommended as you may experience high frequency shrills.
For better earphones such as Monster,Philips,Zombie,Sennheiser, recommended value = 30 ~ 50.
For high-end headphones, value depands on headphone cable length. Start with value = 40, value +10 for every 80cm cable length.
For preamp/amp connect to phone. Start with value = 60, value +10 for every 80cm cable length.
For tube amplifier, directly use value = 100.
(3) Lo Contour. The value defines the percentage of bass contour reconstruction over total band. The larger the value, the stronger the bass, but midrange and details will slightly lost.
For earphones recommend value = 50 ~ 70.
For headphones recommend value = 20 ~ 30.
5. Master Gate(Limiter). This option is V4A output limiter, its used to prevent overloud clipping distortion.
(1) Ouput Gain. This value defines the main output volume. Its something like a volume control.
(2) Limit Threshold. This value defines the limits of waveform amplitude by the limitor, 0 dB is the maximum value.
The smaller the value, the easier to experience audio frequency compression(the smaller the volume), will lose sound details, but can effectively control the final output volume. Recommend 0 db.
Default FIR Equalizer Guide
--------------------------------------------------------------------------------
So how do we adjust the FIR Equalizer?
Before this, V4A use IIR Equalizer, you have to know how much to adjust for each frequency band. But now using FIR Equalizer, you just have to know which frequency band to adjust.
So, determine your desired frequency band and move the adjustment bar to maximum or minimum.
Don't believe me? Try move all frequency bands to maximum and you will notice the high,medium and low frequency sounds strengthen, not just the volume being amplified.
That is the magic of the FIR Equalizer!
Due to FIR equalizer's innate qualities, there's no need of auto level control or gain compensation.
Of course, in V4A future updates, creator will extend the maximum gain value beyond +9 so that the maximum gain effect will be clearer and more obvious.

Try hitting menu key and click on fx compatibility option select normal then you should notice a difference when you tinker around with the settings. You also need to enable it in sound settings- music fx. It is also best to convert it to a system app so that process killers don't terminate it.

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

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 OP with step 6 as optional. Cheers!

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.

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.

[SOUNDMOD] Arkamys port for m9

Arkamys is an audio enhancement from a well known car audio manufacturer
Increase the maximum volume without distortion
Superior audio rendering with no hardware changes (suitable QC only!)
Clearer, crisper sound for music and speech
Higher volume and deeper basses
*How to install?
Just download the zip and flash it through recovery
*How to uninstall?
I suggest you to do a nandbackup in recovery at this time
(maybe later i'll make an uninstaller script)
*How to change effects presets?
At this point there is no way to change the presets
*What version of sense/android/whatever do i need?
This will work for other HTC's, and probably other smartphones with Qualcomm.
Tested on MM ICE10 port for m9 made by Golv and Ice team (should work on lolli as well)
FOR ALL OF THOSE "SOUNDMODDERS" - YOU ARE STRICTLY NOT ALLOWED TO USE THIS PORT IN YOUR "MODS"!

feedback anyone?

Great quality - both on headphones and built-in speakers. I will check later today how it performs in my car

will install it on my OP3 and see how it goes
---------- Post added at 11:12 PM ---------- Previous post was at 10:19 PM ----------
okay i installed it on the OP3
tested with my HTC in-ear buds:
1- I can confirm that the bass is deeper!
2- Overall better sound output with better mids and highs with a little bit soundstage widening
3- No volume boost as far as i am concerned
tested with Anker Sports Soundbuds:
1- I sense more like volume leveler effect here, which makes the sound louder in a "dynamic" way, albeit it is slightly felt
2- Overall better sound output (not that sure about that one) placebo
more in depth reviewing tomorrow when connecting the phone to my sub-woofer set (11 watts 2.1 ch Genius one)
This is just a quick "review"
Plus, I use my Sub-Woofer set way more than the in-ear buds or the bluetooth buds even

I tried this mod hooked up direct to my Chevy truck..it was too me like turning off h/k and nothing else..but like I set it's a Chevy..soo
Æaay..\../

@UltraM8 Okay so I hooked up the OP3 to my sub-woofer, here is what I got:
1- deeper bass and way much less distortion at max volume; the bass is not that thin anymore or overpowered or anything like that
2- lower overall volume ?
3- slight clarity increase
Tested on the OnePlus 3 with no external DSP/EQ + Genius 2.1 ch Speaker System with 3.5" 8 ohms Sub-woofer (6 watts output) and two 2" 4 ohms tweeters (2.5 watts output) with overall output of 11 watts.
Suggestions:
1- An EQ is so welcome to tune it for my liking
2- increase the 60/66/78/120 Hz a little bit for more "booming"
3- Make a general one without the htc_audio_effects.conf file and instead edit the generic audio_effects.conf one, definitely appreciated
Can test it on the M9 in a while, running ICE Golv's 10 port.
Wish all the best! :highfive:

There is not much you can do with presets - those for QC are closed-coded, ones for MTK - there are hundreds of lines, so it will be pretty hard to change anything) About the conf files: so you deleted it in htc ones, right? Cause when i did my testings something was wrong with htc's stock music player (like the effect was unable to connect, or maybe my ears were so tired of testing i didn't hear the difference))
I will ask a guy who made a port of yours OP3 EQ, if he can share his work, or you can help us - just rip everything related to eq in the system))

I copied the arkamys lines from the htc_audio_effects.conf to /system/etc/audio_effects.conf then deleted the htc file since it is a OnePlus 3 here.
Anyway, I dug in the zip and found some files like 0_TUNING, 1_TUNING and so on.. with some saying Bypass
And the xml file setting different profiles for different devices (speakers are off ??)
Are those various profiles ?

|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'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.

????????

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.

Audio recording lacking bass

Hi, I am running ressurection remix 8.1 on my whyred ai, cant seem to work out how to get any bass on my video recordings, on my mido I had to flash some changes to audio mixer files etc. Not sure if anyone else is having this problem but the audio reoding sounds really tinny.
anyone else notice this?

just realised the inbuilt audio recorder is ok, only video apps like google camera and opencamera seem to have the issue?

Ok found a way to get really good audio quality. I've searched across boards and tried a lot of stuff. The volume level might be low(er) but I need to alter another XML file. Good enough for concerts and out in the open I would say.
First you need to change the max bitrate since they set that to 96KHz which is way to low. The file to edit is /vendor/etc/media_profiles_vendor.xml
Almost all the way down that file you see the AAC settings.
You will see
<AudioEncoderCap name="aac" enabled="true"
minBitRate="8000" maxBitRate="288000"
minSampleRate="8000" maxSampleRate="48000"
minChannels="1" maxChannels="6" />
As you see I set it to 288000.
Next is the biggest issue. Seems the MIUI camera standard uses AGC and that high pass filter that up to date I haven't found. Open camera works but the other microphone you can select they go via the noise cancelling stuff which kills the audio and you get an underwater sound.
I have a official licensed cinema FV-5 from the playstore. Now there is an issue for the moment. I cannot record in 1080P (the image zooms in like crazy it seems, I contacted the developer for that). On 4K recording it works perfectly. Also remember in the menu to tab the little shaky hand to switch on the stabilizer as that works miracles.
Now go to the settings - audio - audio source is set to 'built-in mic(video camera)' ------ audio channels - stereo (2) ----- bitrate - 256000 ----- sampling rate - 48000 and very important 'disable audio automatic gain control - is switched on' meaning disabled.
Give it a go.

@junglist @lukesan Hi,
I downloaded Mi Max 3 ROM which is the same SOC and I found some interesting stuff about that!
mediaprofiles.xml in vendor is the same on both devices (at least on 9.5.19.0 which am using right now) but the one in system is different, on Mi Max 3 they changed the aac bitRate in so many lines from 156000 to 192000 which is looks interesting!
Also there’s a trick here, mediaprofiles.xml which is in system is the same media_profiles_vendor.xml which is vendor, same on our device, that means both files must be overriding not only mediaprofiles.xml in system!
here’s a flashable zip from Mi Max 3 ROM for any one wants to give a try, also check out this video which compares between our device and Mi Max 3 regarding this part:
https://www.youtube.com/watch?v=5LKThf9KWjs (09:42)
I still need to perform more testing before I can confirm if this really works or not!

Ok, very cool find! Observations which I made over the last couple of days
We have 2 'issues' on the redmi note 5 (Whyred) so 1) the bitrate and 2) the highpass
1) is as you say media_profiles_vendor.xml we can easily alter that one. Check out the downloadable MI MIX 2 audio quality ... module for Magisk. Download extract and copy that xml file and set the same permissions 644 I believe. Make a backup of the original first. They set the bitrate really high on that one 256kbit/s I believe which is a bit overkill, but compared to 20mbit/s for the video it is nothing and I rather have overkill than 96kbit/s underwater sound.
So that one is easily fixable.
2) The high pass filter seems to be linked to the AGC. I really like the AGC since it keeps the volume constant and should be the standard for the 'normal' people who do not care about extreme hifi things. I would leave it on if I could only switch off the high pass filter. Shoot a video and it will be perfect for 99.999% of the people. Levels will almost be perfect. People easily understandable etc etc etc.
I would like to switch off the AGC (and the filter) for real audio recordings, meaning classical music etc etc .. this involves always having to check if your level is not to low or if the peaks are not to high causing clipping which means distortion.
For issue 2 the only app that I found that can do this is cinema-fv5. I made an error in my previous text to set it to 8MP since then the stabilization doesn't seem to work properly so I now set that to 2592x1296 which seems pretty 16/9 like to me. If you switch off the AGC in this app then you get AGC off and high pass off. Very low level audio but perfect quality. I guess perfect for a concert. (this weekend there is a local festival here so I can really test (and enjoy))
If you want good audio but mono then you need open camera for now. If you set the microphone to 'mono' you will also hear that the sound is good, setting it to stereo gets the noise cancellation working and it sounds like crap.
I'll try those Mi Max 3 things if I find a bit of time. Lets share knowledge and experience and we'll get it working like it should. This is the only small downside of the redmi note 5 that I have found so far. (and that is coming from an S7)
---------- Post added at 10:54 AM ---------- Previous post was at 10:00 AM ----------
@rocker00 Just flashed it. Does set the bitrate to 288kbit/s which is really high but, like said above compared to video that is peanuts. Better a lot more than what it was. But it does not switch off the AGC or high pass. Since you have the rom can you check and attach another file? The file is in the same path (vendor/ etc) our file on the redmi note 5 is called mixer_paths_skus.xml . I guess it might be a bit different on MI MAX but I guess some more audio is being controlled there.

@lukesan First please override media_profiles_vendor.xml manually because it looks like the script is not mounting vendor!
Regarding the file, media_profiles_V1_0.xml, mixer_paths_i2s.xml, mixer_paths_mtp.xml, mixer_paths_skus.xml, mixer_paths_skush.xml, mixer_paths_wcd9326.xml, mixer_paths_wcd9335.xml and mixer_paths_wcd9340.xml
are the same md5! but mixer_paths.xml (which i downloaded the whole rom just to get it in order to try to enable dual speaker) is completely different!
Also i have 2 doubts:
1- in build.prop which is in vendor they changed ro.vendor.audio.sdk.fluencetype to fluence which is none in our device(related to noise cancelling)
2-ACDB (Audio Calibration Database) which is completely different in Mi Max 3 cuz it has dual speaker and two speakers at the bottom, and ACDB is controlled by audio.primary.sdm660.so which is different for sure in both, i hope it's not related to that because it will be really a hard job!
here's the mixer_paths.xml am still looking into it maybe i can find something!

Probably it is taking the media_profiles_vendor.xml which I already edited manually. Well to check that our device is capable you could check with Cinema-FV5 lite which is free up to 1280x720 resolution. Disable the AGC and you get a nice clear sound full audio spectrum. I'm on a 8.7.5 rom and when I start to record my image is taken from the upper left corner all zoomed in. Not sure which rom you are on, but could you give that a try?
If it's that *.so file we need to address someone with the right knowledge. I've never decompiled stuff like that.

I'll try the app ASAP and i'll keep trying...never give up
BTW, that lib is most likely C++ signed binary so you can't do anything about it!

Just came back from the festival that I told about. The default MIUI video cam.. wow made a complete mess. The AGC went completely crazy and no bass. Using cinema-FV5 ... wow listening to it right now with my earplugs..... it's like I'm still there. Ok the bass sounds (only) a bit distorted, but I was standing at the front and the smart people there handed out headphones that dampened sound to the kids. I myself suffer from tinnitus so I have -20dB earplugs ... even then it was crazy loud.
So cinema-FV5 is definitely a must with music. Not sure if I can upload something on Youtube without violating copyrights. But surely this phone is capable of recording high quality audio for sure.

Same happened to me. After recording the stage with artists and loud music. It looked OK, stabilised video at 1080p, but sound lacks bass with stock camera app.
I would like to try better camera apps like gcam, just there are ~50 hours for me to wait till I can unlock my bootloader and flash a decent ROM.
Then we could record at 60fps 1080p and [email protected] with normal audio.

Forget gcam or other roms for now since they use the same audio path. There is another trick I read about but it involves a lot of work and I would hardly call it a working thing unless you spend a lot of time. Check this thread. I know for the MI MIX but same procedure applies for now. https://forum.xda-developers.com/mi-mix-2/how-to/mi-mix-2-video-sound-recording-quality-t3776450
Leave the 60fps and 4K behind if it is in a dark environment. You might end up with dropped frames etc which is really annoying.

Have you tried it? I've tried your trick with the bitrate increase in media_profiles.xml, though I've set it to 192000 and used the FV-5 disable the AGC and it's much better quality! Although the bass is a bit too much pronounced and the meds and highs are a bit sacrificed, it's still much better than stock. But with the custom settings for audio in FV-5 it makes that "underwater" sound, no matter which combination I used, but I did everything according to your post, only if I leave the default values it works. (I now suspect it was maybe because of the stereo recording option)
I am interested to make some changes using the thread you linked, I'm just afraid not to make a mess of volumes in earpiece or introduce echo during a call or something like that, that's why I'm hesitating.
The AGC makes a total mess of recording, it lowers the quality and introduces background noise.
For the 60fps I'm not sure that works as none of the camera app that I've tried are able to record it (I'm on AOSP based rom) because it depends on the camera blobs, and I'm not sure Xiaomi updated the sources, but they did introduce it in MIUI 10 builds.

Strange that you got the underwater sound. Can you check with this one? https://mediaarea.net/en/MediaInfo Just drag and drop the file on it. It will show the audio properties.
Just to confirm again my settings in FV-5 I changed the resolution to 2592x1296 (turn on handshake thing on where you can actually see where you are recording, weird setting I know). In the 'Audio' settings check the attached screenshot.

Oh yes I did that, but you didn't check the "Custom audio settings" box so the app uses default system settings rather than the ones you selected. Try it out if you didn't already.
And I've checked with MediaInfo, the video was recorded in 96K (because the app didn't use custom settings), but anyway it should be using maximum possible values the device has set in media_profiles_vendor.xml, which is in my case 192K. I've seen now that media_profiles_V1_0.xml is basically the same file and there is 96K set as maximum, maybe both files need to be changed?

That's normal since it seems you can't overwrite those settings in our current roms it seems. I bought that FV5 but I emailed support and never gotten answer back, to bad. It always takes the settings from that file on the phone it seems. And yes if you see 96Kb/s than it is normal that you hear these metallic sounds. Can you maybe attach the media_profiles_vendor.xml you have in the /system/vendor/etc dir?

Well recording in 96K instead of 48K which was the case with MIUI 9.5 in GSMArena test is already an improvement, however I'm sure this device is capable of even more. So for now, seems that just disabling AGC made a very good difference, it might just get better if we raise the bitrate even more. I've seen in the thread you linked that they actually modified media_profiles_V1_0.xml in case of LineageOS to raise the bitrate, I will now try that one as well.
Here is my file you requested.

I confirm that changing the media_profiles_v1_0.xml does increase the bitrate! I have set it to 192K, however since the maximum value that was set for each resolution (I've tested 1080p) is 156K the app used that one based on previous setting. Now every app should use the 156K if we don't alter the bitrate for each resolution separately (that's my guess at least).

I tried this app with the steps you mentioned and yeah, sound is better for sure but it's much better if we can get the same result on stock cam.
let's take it step by step, first is the bit rate, even after using Mi Max 3 files the bit rate remains the same! i checked my old Sony Xperia z2 mediaprofiles.xml and i found the aac bitRate is also 192000, see the video sample result in the 1st pic from sony and second one from note 5 pro!
Now clearly there's something controlling the cam audio beside mediaprofiles.xml since the modifications wasn't enough!
I'll record a log while recording and let's see if i can find any info about that!
@Cirra92 60 FPS is working on 9.5, i thought like you about blobs but surprisingly no! now i'm on 9.5.19.0 and i just got the camera apk from MIUI 10 and i have 60 FPS!
Also i found another thing which is interesting but it's still not working even on Mi Max 3.....looks like 120 FPS HFR is on the way!
Check this video out: https://www.youtube.com/watch?v=0rjZx_5JD1s (13.06)
I managed to get this setting even if it's still grey!
etc\device_features/whyred.xml just added those lines:
<!--whether support camera video high frame-->
<bool name="support_camera_video_high_frame">true</bool>
let's try to make the cam perfect as much as possible!
