Well we can have a eternal discussion about this,"adiophiles" vs audio equalizer enthosiastics" viper4android is the best thing we have if you're a heavy equalizer user

It doesn't get better than that for android devices atm => Well... maybe with a hardware equalizer directly controlled from the kernel and DAC chip, there were some mods of that in the past with the wolfson dac chip from old android devices

For my personal use I cannot miss viper4android, clean default DAC sound is sounding dull for my "audeze insine 20 inears" for example

Poweramp and neutron does not the job well enough, not by far compared to viper4android :)

Technical speaking 16bit vs 32 bit rate is an improvement, but only by a small margin for my ears it's not worth letting go V4A

What DID improve the DAC was forcing the dac in high gain mode (other mod on this forum), this was a significant improvement imo, also audible in MP3's not only flac
[LG V20 Themes, Apps, and Mods] lyrical1278:
Here is the thing, you're speaking to opinion. I'm speaking to technical fact. When you use V4A, any audio you use is merely being amplified by the DAC and not being processed by it. Why do you think V4A doesn't work with the mod enabled? It's because Android is being set to run 16 bit audio through the DAC for processing and amplification. Thus, V4A isn't even touching the audio with this mod.

So, if V4A isn't touching 16-bit audio with this mod, then it's not even touching 24-bit audio by default. So it does the only thing it can do, it downsamples (since it downsamples any audio above 16/44 by default anyway, whereas Android's mixer upsamples to the max capability of the DAC). I cannot speak to what you feel is dull and such. That's your truth based on your musical ears.

All I am saying is this, V4A is nothing more but an EQ. A VERY GOOD one at that. If I didn't have the V20 or the Dragonfly Black, I would still be using V4A. But I don't because I have those tools at my disposal. Grab poweramp Alpha or Ainur and you will see the DAC come to life. V4A, and anything after this is my opinion, doesn't do anything close to what an app that lets the DAC do its job can do.

Installing V4A on this phone, again, my opinion is a waste of the full abilities of the DAC.. Using it just turns the DAC into an amplifier instead of allowing it to be the thing that processes audio IN ADDITION TO amplification.
[LG V20 Themes, Apps, and Mods] mookiexl:
Didn't know I could enjoy music on my phone without viper. All my mp3s/flac sound more lively. To my knowledge Power amp 3 still downsamples. Is the availability of the built-in equalizer a good trade off for the lost sample size?

Edit: Both viper and Dolby are broken with this mod
[LG V20 Themes, Apps, and Mods] lyrical1278:
You could try blackplayer... It doesn't downsample. I use that because it also has an EQ and when I use my VE Monks, I need to tune the bass down
[LG V20 Themes, Apps, and Mods] mookiexl:
Apparently the equalizer attempts to downsample once activated and you get no sound with this tweak. Oh well I'm good knowing I'm actually getting the most out the DAC at all times.
[LG V20 Themes, Apps, and Mods] KUSOsan:
While this phone without viper sounds night and day better than any phone I've heard so far, viper still sounds the best with Poweramp imo
[LG V20 Themes, Apps, and Mods] BROKEN1981:
Forcing it into High impedance does nothing for music quality.
[LG V20 Themes, Apps, and Mods] jody2k:
It really depends

Some headphones do like the extra power, headphones with low impedance who are still powerhungry for example. For my audeze isine 20 it made a difference

Some audiophile headphones like the extra voltage, fact they are low impedance doesn't always mean they are easy to drive
[LG V20 Themes, Apps, and Mods] lyrical1278:
Do you mean V4A becomes broken? Because I am using BlackPlayer right now with the EQ activated (Blackplayer's built in EQ, not V4A) and I am having no issues plus there is no downsampling.

But yes, as I said in an earlier post, V4A will become broken (as will most audio mods) if you use this build.prop mod because the DAC will be handling 16-bit audio processing directly instead of it being bypassed and handled by the audio mods.

---------- Post added at 03:44 AM ---------- Previous post was at 03:41 AM ----------

High Impedance doesn't affect quality, it affects loudness. Since the amp in the V20 is actually pushing the headphones, the headphones are able to play louder. The quality is affected by the DAC whether h.i. is on or not. The quality doesn't change (unless you're into letting your audio clip), its just able to be louder.
[LG V20 Themes, Apps, and Mods] jody2k:
I'm not gona try to learn a donkey maths, i'm not talking about more volume it does more than just that. you clearly don't know what you're talking about and as in contrary you read on hi fi forums you don't know anything about soundquality or how it affects ears/headphones

You're an idiot yes that right I'm gona ignore you from now
[LG V20 Themes, Apps, and Mods] BROKEN1981:
It only makes it louder. Just people say it does more then that on HiFi fourms does not make it true.

Just Google ohms law. It has no effect on audio quality. If you think High impedance makes better audio quality, then you have no clue as to what you are talking about.
[LG V20 Themes, Apps, and Mods] alldine345:
i dunno why you praise v4A that much, but here is what i tried. i used v4A on my v20 with Razer adaro DJ, KZ Z26, and puresound 260ohm earbuds. it sounds great until my brother in law bring his cord mojo and Fiio Q1 Mark II dac/amp. no matter setting that i use in V4A i always got "buzzing" on my headphone/iem/earbuds. the bass were enough but i lost the vocal and instrument quality. it get worse when i use fiio as a dac. restore my backup and testing without V4A. and guess what? every noise and buzz gone. fiio as amp really blowing every sound aspect from my v20. more soundstage, neutral sound, etc. so yeah, if you only use v20 and iem v4a might be best for you but once you use external amp or dac it became useless even downgrading sound performance.
[LG V20 Themes, Apps, and Mods] jody2k:
Buzzing from your ear buds?? Maybe you did something wrong badly

And you lost vocal and instrument quality yes let me guess what you did: you boosted the bass options without boosting the low mids, mids and high's because you don't know how equalizing works because your that kind of audiophile who strives after pure neutral sound.

Ofcourse the chord mojo is on a other league here it's alot better yes I tried it too but no equalization options soo i was bit dissapointed afterwards, i loved the pure sound it was giving tho and maybe the only dac i could use without EQ but then again there is so much potential lost ... So sad

If the mojo could be paired with a decent EQ then this would be majestic sound i agree

Tried several DAP's from sony the nwzx2 was the one who came closest maybe even better yes but damn the price of that thing

I don't know why you guys try to dishonor v4a it's really good and all about the settings you use
[LG V20 Themes, Apps, and Mods] jass65:
ok, so this actually made a huge difference to SQ especially when you max out the volume.distortion is gone.Honestly v4a is what i used for SoC amp only devices.I have v4a for v20 and v10 but personally it sounds best straight through dedicated amp, no interferance. Even though i have v4a, never use it.v4a is redundant for clarity on v10,v20,v30. you cant beat a dedicated amp with software sound filters.It's useful for tight bass or shaping to your sound curve.Great find OP.
[LG V20 Themes, Apps, and Mods] jody2k:
And again lets compare apple's with pears ofc a dedicated amp will always be better
[LG V20 Themes, Apps, and Mods] BROKEN1981:
Needing extra power is very different then sound quality. There are earphones that go for 3k that are only 16ohms.

Just want to add, I love v4a. Not knocking it, but it kinda kills the sound quality on the v20.
[LG V20 Themes, Apps, and Mods] lyrical1278:
So, since you can't prove anything I said is wrong, btw even on headfi forums, they have shown v4a downsamples... There is even a command you can type in command prompt that shows V4A downsamples. Go into the V4A forums and you will find that the driver is limited to 16/44 (or 48). But you can call me an idiot all you want.

Little of my information comes from anything other than looking into things for myself. But you want to go hard body for an equalizer that basically makes the DAC in the v20 USELESS for audio processing and just an amplifier.

Amusing how you resort to name calling when the very forums you frequent, namely XDA, back up everything I have said thus far. So, you're saying nothing but idiots are on XDA now? Check this thread right here on XDA and go tell them they're "dishonoring" V4A

https://xdaforums.com/v20/themes/list-music-players-dac-t3536815

Or are you, since you find the truth so hard to accept, stuck on people dishonoring V4A when no one is disrespecting V4a by speaking the truth to what it ACTUALLY does and how it ACTUALLY impacts audio quality...
[LG V20 Themes, Apps, and Mods] jody2k:
You can throw me anything of your facts you want, to my needs and ears it's not an improvement it's a loss of fuctionalities.

Only your own ears are telling the truth, for me viper4android is pushing the boundries where i want it and what i want. This soundimprovement mod can't provide this simple.

I don't care what people say but trying to discredit v4a i will speak.

Using viper4android on this device is a night and day difference compared to the galaxy s7 for example. It's using the dac right, downscaled then but still best results i ever heard to my needs and ears

Many people are still using viper4android on this device for several reasons like mine: go have a look at WETArom for example
[LG V20 Themes, Apps, and Mods] beavis5706:
Right here is exactly why I stayed out of this argument. Proving whose audio sounds better is nearly impossible. Technically speaking lyrical1278 is correct on this. Viper4Android does indeed run at 16-bit 48kHz. There is no getting around this. However who am I to say that Viper doesn't sound better for some people. Sound quality can be very subjective. Perhaps some people prefer the sound of 16-bit 48kHz. It certainly does have an "edgier" sound, more rough and not as smooth as ESS DAC..

However I do have to side with lyrical1278 on his one. If you are going to use Viper4Android you may as well be using any phone that uses the internal DAC instead of a dedicated one like the V20 has. You will get absolutely no sound quality benefit using the V20 in conjunction with Viper4Android. Viper will process the audio as it would on any ordinary phone, at 16-bit 48Khz, completely negating the effects of the ESS DAC 32-bit 192kHz output.
[LG V20 Themes, Apps, and Mods] lyrical1278:
Here is the thing, I TOLD this dude I can't speak to what he hears.. i SPECIFICALLY Said, from a TECHNICAL STANDPOINT. I'm not arguing what he hears. He is acting like we are doing V4A a disservice by explaining how v4a affects this phone FROM A TECHNICALLY STANDPOINT.

What he hears, no one can discuss, it's what he hears. I don't like the sound with v4a. What I hear is different and I don't like it. The down sample is noticable to me from 24/96 (which the majority of my files are) to 16/48. So I don't mess with v4a.

What I don't appreciate is the childish name calling. If he would've actually read what I said, that could've been avoided. I want attacking what he hears. What he hears and what's being done from a TECHNICAL STAND POINT are two different things.
[LG V20 Themes, Apps, and Mods] bond32:
I really appreciate you bringing this discussion up and providing us that little trick. I can honestly say I notice a substantial improvement. I'm no audiophile. I swore by v4A, and who knows maybe I will try it again for funzies.

Thanks!
[LG V20 Themes, Apps, and Mods] mookiexl:
Just to follow up on this, V4 does still work for me but only with bluetooth where I assume the DAC isnt being used the same way as a wired headset is used. To test the sound quality I downloaded Mozart and played the 24bit 96KHz file using viper settings like I normally use through my tsunami Bluetooth speaker and then used an auxiliary cord to connect the phone wired directly to the speaker. Sound through viper seemed to have much more aggresive lows and was a bit louder than having the phone wired to the same speaker but with just being wired to the speaker every single string sounded better, so much so you hear detail that I couldn't capture with V4. Anyone who wants to test the effectiveness of this tweak, I advice to do so in this manner. Get some good Hifi files without vocals and I can almost guarantee you will hear the difference in clarity and sheer crispness.
[LG V20 Themes, Apps, and Mods] jody2k:
OR on v4a you can just boost 4K to 16K range it will also be more crisp and clear

Dont use v4a without boosting frequencies of the EQ, why would you install it otherwise?

V4a on default the highs are rolled off yea its because of the driver, it has always been like this on any dac or amp

It's all about settings, when you record a guitar line in studio its all about the mix, layer per layer of EQ. You can make something ****ty sound amazing
[LG V20 Themes, Apps, and Mods] BROKEN1981:
People will always defend their favorite mod no matter what.

That's why there is no point talking about the technical aspect of the subject.

Look how many users defend custom ROMs even though is breaks most features you paid for leaving you with 1/2 a working device.
[LG V20 Themes, Apps, and Mods] lyrical1278:
noted for sure...
[LG V20 Themes, Apps, and Mods] jody2k:
Here the thing in audio its simple i'm gona give you a example: technically the hd 800 from sennheiser is better than the hd 650. Still to my ears i liked more the hd 650 and i'm not the only one. It's not because something is technically better on paper it's sounding better automatically.

Again my ears are the benchmark, i have been years on hi fi forums i have learned something from these years: i follow suggestions but in the end I only believe my own ears. Audio is something very subjective

I know alot of people who like soundquality more from LP's than CD's and we all know CD's are technically better

I'm sure you get the point so stop this discussion it's pointless and stop bringing down v4a

It would be a nice feature to add 32bit / 196K into viper4android, still i would never use it as a standalone mod without viper4android

Because simple: The amount of earth shivvering bass it's delivering without any bleeding in the mid's (the option "dynamic system")

And the lossless analog sounding EQ without any bleeding too and 0 distortion

It might be a brain trick thing but the soundstage i'm getting from viper4android with the option dynamic system is comparable on drum kicks i noticed on festivals: Sound is just enormous

music in general sounding enormous, i'm on the festival stage next to the performer with a holographic soundstage on my Isine 20 from audeze

Mid's are warm/lush sounding and insanely detailed and high's are sounding nice with a kristal timbre in it

Listn I know what good soundquality is I tried alot in my life but i'm gona tell you 1 thing, no EQ can deliver that amount of power (not in software) in exception with viper4android
[LG V20 Themes, Apps, and Mods] BROKEN1981:
1) music-ears food-taste will always be subjective. That's why they brought up the technical points.

2) I don't think anyone is bringing down V4A. Even still, no need to defend V4A as you have been. Name calling goes against XDA. Though there are a few examples when you get frustrated and just do it.

https://xdaforums.com/v20/help/10p-q-h918-root-t3714333

Also when you brought up "It would be a nice feature to add 32bit / 196K into viper4android", I would actually want to use V4A at that point.

Many people including myself bought this phone just for the quad DAC. To kill it with V4A will not make much sense to me and many others.

That's when taste becomes subjective. To each is there own. V4A will always be a powerful EQ. Just needs an "upgrade".
[LG V20 Themes, Apps, and Mods] jody2k:
i've been longer than you on XDA so don't tell me what the rules are

I know one thing, you guys pissed me off and that's how i react when i'm really pissed off against the rules or not i don't care

I helped alot of people on this forum in the past, i accomplished things, people like you is why many good dev's have left this forum in the past

I was looking for implementing a kernel with a software based hardware equalizer acces right from the dac, but i have changed my mind

I don't need poeple like you ****ting on everything who has been proven as years as amazing software

This is my last thing i will ever post here: i'm gona enjoy my music and leave this section of the forum

[LG V20 Themes, Apps, and Mods] LastStarDust:
Hello,

I wanted to give V4A a try but I didn't like the installation process (and the uninstallation process even less) ... on top of that, I didn't like the V4A sound when compared with the plain Quad-DAC. Then I stumbled across this thread and I finally decided to uninstall V4A and apply the "build.prop" fix.

But the uninstall procedure for V4A was a real pain in the ass, and I am still unsure if everything got back to normal or if I screwed something up in the process.

Is there a way to make sure that everything is working in the right way?

I am using PowerAmp PRO and I have attached a screen-shot of the "Settings/Sound/Advanced Tweaks" tab. I am under the impression that "MusicFX" shouldn't be grayed out ... or is it normal?

Are there other ways to check that everything is fine and that I haven't screwed up something by installing and uninstalling V4A?

Thanks
[LG V20 Themes, Apps, and Mods] dudeawsome:
really simple method of install off V4A would be through magisk and uninstall is simple too for future reference
[LG V20 Themes, Apps, and Mods] LastStarDust:
Thank you for the tip. Unfortunately I've used SuperSU to root.
[LG V20 Themes, Apps, and Mods] alldine345:
i remember someone posted in xiaomy subforum about removing unecessary viper files because even though you already uninstaled it, viper also replacing some audio libs and config. unless you had a backup of that file you cant back to "normal" mode. best solution is to reflashing your whole rom. i know it really pain in the a$$ but the choice is yours :D:p
[LG V20 Themes, Apps, and Mods] LastStarDust:
You are killing me, I have just spent a week rooting and tweaking everything and now I should go back to the starting line again.:eek::eek:

What is the quickest way to reflash the ROM without losing the root? Would be a reflash of the system partition enough?
[LG V20 Themes, Apps, and Mods] 3mL:
Perhaps a KDZ-writer flash would suffice.
[LG V20 Themes, Apps, and Mods] LastStarDust:
Thank you. So a `kdzwriter -a <somekdz>.kdz` would suffice, wouldn't it?
[LG V20 Themes, Apps, and Mods] 3mL:
Yea, but -s should probably do the job.
[LG V20 Themes, Apps, and Mods] LastStarDust:
Done. But the Poweramp MusicFX option is still grayed out. Is that normal?
[LG V20 Themes, Apps, and Mods] 3mL:
No idea, I do not use Poweramp.

But a -s flash should remove any remnants of viper.
[LG V20 Themes, Apps, and Mods] LastStarDust:
Thank you anyway for the help!
[LG V20 Themes, Apps, and Mods] shadavis08:
If you want to remove any remaining viper parts. First use the Divine Beats Uninstaller on Divine Beats thread. Then open file manager and go to system/etc. And delete any file in that folder with the name viper in it. Done.

There is no need to reflash a kdz. For that matter you could just dirty flash whatever rom you are on.
[LG V20 Themes, Apps, and Mods] LastStarDust:
Thank you very much for your advice. Anyway once I have reflashed the kdz (as I have), there is no need for that procedure, isn't it?
[LG V20 Themes, Apps, and Mods] shadavis08:
If you do what I suggested there's no need to flash the kdz unless you want to just for fun otherwise no

Hi there,

I have been reading all of the 6 pages of this tread. I stiil have a doubt. A tech question.

I am on LG V20 H990DS, rooted with dirty santa, 2.3 kernel. Everything is running like a charm. I am still in love with the DACS, and surelly it is a wonderfull upgrade.

The question is:

- If i install Viper4Android, and don't choose to use this 16bit tricks explained here, can i still use de DACS with all your fulness, playing 24bits files like those hifi flacs files?

- Is there any possibilities that viper files does something wrong to use the DACS?

I will try to make more clear:

I want to hear 16/44 using viper and hi-fi files 24/92 using the Dacs.

Is this possible only to choose make on - off option on Viper?

Thanks in advance for your kindness and attention.

Edit: Please, accept my apologizes. I am in the wrong tread, and found out the correct one for ask this kind of question; the viper one.

Thanks anyway.
[LG V20 Themes, Apps, and Mods] jody2k:
You can test this far more easily on your computer

Right click on speaker icon - playback devices

Double click om your audio device: go to advanced tab

Switch between sample rate there and try to notice any differences between 48000hz and 128000/96000 hz

Wow such difference :) NOT

Difference is so subtile i'm not even sure it's worth to call an improvement

Do yourself a favor, use viper4android am never look back and

Ignore these ocd suffering "audiophiles" here
[LG V20 Themes, Apps, and Mods] lyrical1278:
Ok, this is what you ACTUALLY can do, contrary to what someone else said in a previous post...

Basically, you can switch viper off and on (it does have a switch within the app for that). Any audio ran through Viper will be amplified by the DAC, should you have the DAC set to high impedance mode but the DAC will not be doing any processing. Viper handles all that since all audio will be processed by Viper.

Now, as to if the DAC will handle any audio, as per your question, when it is turned off is another question. But, it wouldn't hurt to try. Just back up your ROM prior to flashing Viper, give it a try, and if you like the results, keep it as is. If you don't, then you can always restore the back up.

Also, as a side note, changing the sample rate in Windows does nothing unless you are playing audio files that take advantage of the sample rate. The built in audio files in windows don't do that.

On, one more thing, Jody once commented that he would make something that would take advantage of the DAC and earlier posts stopped him from doing that. Ainur does it already (which I use and recommend using)... USB Audio Player Pro (which I use), Black Player also do that (something I have used in the past until UAPP did it). So what would you develop that hasn't already been done?
[LG V20 Themes, Apps, and Mods] sptw:
Thanks for your input lyrical1278. I really appreciated that.

I will try your suggestion and see how it works. As soon as i can, i will just do a backup of the rom, and flash the viper on twrp.

Once again, thanks for your attention.
[LG V20 Themes, Apps, and Mods] toastyp:
[MENTION=1608430]lyrical1278[/MENTION] I was wondering how you use ainur sauron. I've flashed it a few times with out any real change in audio. Looking through the zip, it's just a bunch of drivers and no interface to enable them. Every other audio mod has .so files and a gui to use them. I've read through his forum and everyone says to use a system eq (like viper) but that ruins the dacs functionality. I've read that the drivers are enabled by default after flashing, but the music just sounded flat to me and broke the music fx eq. So what options do you use when installing it and what equalizer do you use (that doesn't break the dac)?
