That's true. But turning them off make only a marginal difference.

Just as now, I never used V4A for phone speakers. I don't know how much difference such tiny speakers can make. That phone was running fine until the previous night. In the morning, I found it dead. I thought the battery must have drained. But it turned out to be the motherboard.

Reason I suspect V4A is because it makes the hardware work much harder, beyond their safe operating limits. If not, why is V4A so difficult to install? V4A installation is a problem for every brand of smartphone, as well as computers.

I thought so too. But as I mentioned before, I 'distinctly' remember how some songs sounded back then, and how they do now. Assuming my ears are still fine, I can only think the problem could be either because of bluetooth (wired is still way better) or because V4A has changed.

It's not about the changes you have done. I read someone saying that version 2.1.7.6 (or something like that) is better than 2.7.2.1. So asking if another version could be better?

Back in 2015 too, I read several posts which advised against updating V4A versions, if the existing version is working fine. Given the diversity of Android devices, a newer version may not sound as good on one device, as it does on another. So users were advised to stick to the version that works best for them, even if they are older versions.

@TheMystic

Have you tried several different convolvers?

They really make all the difference with Viper. I've got a huge collection to choose from. So there is always something appropriate for different occasions.

My most favourite are HTC BoomSound Z and ZS-Edition.

JFYI
[Android Apps and Games] TheMystic:
Can you share them? I have none.
[Android Apps and Games] shadowstep:
It's not about difference, big or small, it's about conflicts. Multiple apps/mods doing the same/similar thing can break stuff, is all.

Not a lot, but they do make my phone's speakers sound fuller and much better, so.

I don't think it could fry a motherboard, is all. Things like overclocking, bypassing thermal limits, etc. carry way more risk than using V4A. Plus it isn't processing all the time, only when an audio session is open.

It's not difficult to install from the POV of the app - installation has become difficult over time because different OEMs have changed paths to the files V4A installer patches thanks to new android versions, etc. Remember this isn't an actively maintained app anymore. Had that been the case, the installation would've been as easy as it was earlier.

There were two versions of the app that were available for use back in the day - both of them had different drivers; the older one had older drivers (which supposedly sounded better) and the newer one had newer drivers (which weren't as good as the old drivers). Personally, I've never felt much difference between the two, but that could be just me.
[Android Apps and Games] mrjuniork:
Sure. Here you go. Paste them into the Kernel folder.
[Android Apps and Games] TheMystic:
I agree.

I hadn't done any of the above stuff. The only 'mod' I had flashed was V4A. I had only a couple of root apps like Afwall+, Adaway, Titanium Backup. Rest everything was pretty much the usual stuff, including stock ROM, Kernel, etc. That's why V4A becomes the suspect. But anyways, this is an old story now.

If you make V4A mod with the old driver, please let me know. I had tried several V4A mods back then, and i found the 'stock' mod (the original one) to be the best. I was using Sony MDR-XB55AP back then, and the experience was just too good, on the Samsung Galaxy Note 2. The experience wasn't as good later on my OnePlus 3T using the same earphones.

Now, on the 8T with the new Bluetooth earphones, the experience is actually no where near the above two. Apparently the newer Type C ports require the newer adaptors, and i don't have one. The one I have works fine with my Huawei tablet. So nothing wrong with the adaptor. If I get hold of the new adaptor, I'll be able to test and tell the difference.
[Android Apps and Games] TheMystic:
Thanks very much. I'll try them out and let you know.
[Android Apps and Games] TheMystic:
I tried many of them, Unfortunately, none of them are working properly. In fact, most of them are causing severe distortions, including the ones you named. I'm on stock Oxygen OS 12 and everything is stock (except root).
[Android Apps and Games] mrjuniork:
That's very odd. I have a super crispy Sound with that specific convolver. I'm using the OP wired bullets, and it's really super clean and perfect bass Output.

Try playing around with the Equaliser and several other settings.

I'm on A12 custom ROM, OP6...
[Android Apps and Games] TheMystic:
If you read through my history with V4A, you would note that my previous experience was with wired earphones. I do remember when i used to stream music to my soundbar over bluetooth in those days, it wasn't a good experience even then.

I'm beginning to think this V4A is not too good for sound over bluetooth. The reason why the convolvers you shared aren't working on my device could be because of stock OS, Kernel, etc. May be your custom ROM supports these tweaks. Also because you are using wired earphones, and i guess your phone has a 3.5 mm jack.
[Android Apps and Games] TheMystic:
@shadowstep

@DiamondJohn

@mrjuniork

So I pulled out my over 7 years old Sony MDR-XB55AP from my drawer and connected it to my FiiO DAC (to make it work over bluetooth since my Type C to 3.5mm adaptor isn't working with my newer phones):

The sound is mind blowing! If I increase the volume over 70%, it will blow my ears away. 😍😍

What am i supposed to make of it?

My experience now is similar to how it was back in 2015. 😍😍

Are the bluetooth earphones still no match for the wired earphones? I know the DAC here is playing a big role.

Should we conclude that OEMs are stupid to remove the headphone jack (which used to have an integrated DAC)?
[Android Apps and Games] zgfg:
Have you tried James DSP (together with or even instead of V4A). I use both plus Equalizer - Bass Booster (Google Play, no root app)

Hard to judge but I was also disappointed with V4A last years/latest version/on my newest phones (while V4A also used to be one of the main reasons to root each my subsequent phone)

But I thought it's maybe subjective: years ago I was junger, we listened to music with more passion and concentration, speakers and stock drivers were worse and they really needed V4A to improve the sound, and so on
[Android Apps and Games] TheMystic:
I tried it back then, and among several mods I tried, V4A was a clear winner. That impression kind of stuck with me till date. So I didn't try anything else now. What is IR you mentioned within brackets?

My Samsung phone isn't rooted. Can you share the app on Google Play Store that you are talking about?

While it is true that the audio systems in phones have come a long way, the lack of a DAC still makes a big difference to the audio experience. My wired earphones with several hundreds (even thousands) of hours of use still sounds so good with the DAC, compared to my bluetooth earphones that cost roughly 10 times more.
[Android Apps and Games] zgfg:
1) Typo "or even without"

2) https://play.google.com/store/apps/details?id=music.basss.booster.effect.equalizer
[Android Apps and Games] TheMystic:
Okay.

Looks like the app you linked isn't available in my region. Can you share the apk?

How does it work? I have to turn it on each time i play some media file?

Is it similar to Wavelet?
[Android Apps and Games] zgfg:
You can find practically all apps from Google Play on ApkMirror (original/legit apks, plus older versions, without troubles requiring to install some shopper application or similar spam to be able to download)

Didn't use Wavelet, probably similar Edit: Bass Booster seems more friendly to handle

Open, leave in background, dynamically adjust knobs, sliders, etc - see the screenshot
[Android Apps and Games] TheMystic:
That's true. The problem is there are often multiple apps with similar names, so one is not sure which one is being suggested.

But never mind. My Samsung phone already sounds good enough, and now that V4A is working quite well on my OnePlus phone with the DAC, I'm sorted for now.
[Android Apps and Games] DiamondJohn:
If you want audio quality, never use Bluetooth. In my car, I could use bluetooth, and it would be handy, but luckily, I have a wired AUX for music and can use the Bluetooth seamlessly for phone functions.

As for a DAC (Digital-to-Analog Converter), all digital audio uses a DAC. It is what converts the ones and zeroes (ie digital/binary/bits) to audio. For Bluetooth, the DAC would be in the receiver.. What are you using the term DAC to mean when you say "lack of DAC"?:
[Android Apps and Games] TheMystic:
What is that item (FiiO) then? Amplifier?

With it, I get a very similar experience that I got with my Note 2 in 2015-2016. Back then, I had used the same earphones directly connected to the phone. This item was not there back then. I only bought it in 2018 to use my earphones wirelessly. Then much later I bought the bluetooth earphones, which sound quite good, but I see that the wired one sounds better.

What is missing with the new devices? Both my phone and earphones are premium devices. They sound great in stock form, no doubt, but something is missing that this FiiO + Wired earphones offer. especially with V4A. Is it just amplification then? If so, how was my Note 2 able to offer such great sound without this device?
[Android Apps and Games] Divyang Khare:
One of the Great audio mods for android devices....

I have installed in some of my devices through both methods i.e. rooted and non-rooted...

But whenever I tried to install through rootless method(i.e. flashing rootless zip file through recovery and installing apk as regular app) in my pixel 4 it shows driver not installed and requires root permission...

Some of my redmi devices don't get any error by this method...then what's the matter with pixel 4..

Can someone please help to resolve this issue...
[Android Apps and Games] zgfg:
Maybe the driver files on your Pixel 4 are in different directories and what TWRP installs goes to the wrong place

Or (more likely - you should know about your phone and ROM) System on Pixel 4 is read-only and TWRP cannot change/overwrite - that's why Magisk provides the so-called Systemless mechanism (eg, /system/etc/hosts can not be overqriten, instead AfAway writes to a file on /data/adb/module s/... and Magisk takes care to mount that hosts file over the one on /system)

Obviously, for the Systemless 'rooting' , Magisk is required - and V4A can be only installed through Magisk (eg, like Magisk module)

New phones with new Android versions do have that read-only System As Root, requiring the Systemless rooting
[Android Apps and Games] zgfg:
My Xiaomi 11 Lite 5G NE came with a nice looking wired headset (however, for USB-c since there is no 3,5 mm port) - the whole boxing was good value for the Lite model and price

When plugged in, a stock equalizer pops up with decent options - screenshots attached

And the sound is pretty good. In fact, although V4A claims Processing Yes, I was not really able to improve the sound (I do but hardly hear a difference)

With James DSP, I can certainly hear the difference (but distortions when I eg exaggsegarate the reverberation)

All together, although I do have both V4A and JanesDSP successfully installed (nowadays many claim troubles to install V4A and I was also needed to manually modify V4A module to make it work with my drivers - with the original V4A, its app was repetitively claiming no drivers found, 'install' and reboot, and the same all over again ), I don't really need all those sound mods - the stock equalizer plus a booster from Playstore work good enough for the accompanied headset at least for jumping from one song to another on YT (as our concentration allows nowadays)
[Android Apps and Games] TheMystic:
If possible, give it a try over bluetooth earphones and let me know if it sounds just as good.
[Android Apps and Games] zgfg:
I have Huawei BT earbuds but something is wrong with the right bud battery (it empties to 5% while the left is still above 90%)

The accompanied app is limited compared to the mentioned Xiaomi stock equalizer for their USB-c headset hence I have to use V4A and/or JamesDSP - I could improve the sound but not that good as with the mentioned Xiaomi wired headset and its equalizer
[Android Apps and Games] TheMystic:
No one answered my previous question, so I'm still not sure what is causing this difference in my case. Does the (erstwhile) headphone jack have more to it than just being a way to connect earphones? I mean do they also have sound amplification feature?

Because my Note 2 sounded really impressive with V4A. Even the Xioami Note 4G (1st Generation) sounded too good with everything stock.

The new phones don't have that 3.5 mm jack, and there is something lacking (speaking relatively) with the sound over bluetooth. At the moment, it appears to be just amplification, but I'm not able to say that with full certainty.

[Android Apps and Games] zgfg:
V4A installs as Magisk module.

It installs sound overlay files to

/data/adb/modules/ViPER4AndroidFX

where Magisk is supposed to read and process on every reboot

Even the V4A app does the same - at least for the phones rooted with Magisk

However, you could try with V4A app as suggested (maybe the app might detect that your phone is rooted and System is not read-only and make the changes directly to the System instead of through the Magisk mount/overlay mechanism).

I never tried that way (and cannot on my phones with read-only SAR where rooting works only the systemless way with Magisk - all new phones)

Btw, good to see that good, old Huawei P9 is still in use

In my Music player (Vinyl Music Player from the play store), I can go to the song full screen (as opposed to just playing a selected song from the list) then use the menu to pull up the active equalizer. If it does not pull up viper, then you have to disable the one it IS pulling up.

[Android Apps and Games] zgfg:
Yes, on my new Xiaomi I have both but I JamesDSP works better than V4A for me
[Android Apps and Games] DiamondJohn:
Generally speaking, you should only have a single audio modification when running Viper; and with viper I mean viper only. The Magisk module actually explicitly disables ones found commonly on other ROMs; but not JamesDSP. Installing more than one at the same time is asking for it to fail. Some may get it to work, but its not the way to go, especially when you are having problems. Try each, but uninstall so you only have one, for better chances of them working.
[Android Apps and Games] sachinachude:
I had removed jamesDSP then clean installed viper but no luck (i have used single magisk module but have same problem). Same viper magisk module working fine with Android 10 on another device. Both devices are from same brand Nokia but different thing is that they are from different processor like Android 10 on snapdragon and Android 11 on mediatek.

I have both of them, by help of AML and both work

Actually, I first had JDSP, then uninstalled and managed to install V4A but after the experiencing with both (separately), I put back JDSP and keep both, but I usually run only JDSP

As posted a month or more ago, I have better sound with JDSP than V4A (years ago, with the previous phone, it was opposite)

Unfortubately, V4A is not updated for few years (2.7.2.1) and does not keep up with new machines.

To the other side, last week or so I got update on JDSP

V4A seems to be broken on Android 13; when opening V4A on A13 it wants to install the driver (+ reboot), but after that's done the app still won't work. The Android 12 "workaround" via changing a single file does not work.
