Viper4Android vs. Wolfson Audio Control, which one's better?

Hi! Like most other people who got their GT-i9500, I purchased mine for 1 main reason, the Wolfson Audio Chip. I was thankful that the Wolfson Audio Control was built and is now incorporated into both Perseus and Adam Kernel. I am planning on flashing a 4.4Kitkat Custom ROM, but unfortunately, there's no custom kernel for this OS that has this feature.
Now I have seen this Audio Mod called Viper4Android. For those who have tried this, esp. you audiophille guys, would you consider this as a good replacement for the Wolfson Audio Control, better or inferior? I am also concerned about the volume levels, will I be able to boost those if I use this Audio Mod? Further enhancing the sound quality of our phone esp. through the headset is useless if you can't boost the current volume levels.
Many thanks!

I'm currently running Viper4Android on stock 4.4.2 but I don't think I can control the volume level, so it's kinda low.

Viper all the way. It's basic and simple with alot of features. It gets the job done. For headphones and car.

Sound Premium mod

Hey, does anyone know if there is any update to this app? since it really gives a very good sound, deep bass and very clear highs, but this app is like the year 2015 and the one that brings "linage os" which is Audio Fx for me is not good at all.

Looks like development of this dsp mod has not been active since about 2014.
In case you're not rooted, you may want to try another sound effect app such as Equalizer Pro or equivalent for systemwide sound processing.
And if you are rooted, there's obviously nothing better than Viper4Android or mods based on it with add-ons like Dolby/MaxxAudio ( such as ARISE)

Dirac Audio Sound Enhancements Service

custom rom missing its charm without this, stock has it.....as well as snapdragon audio.
dont you guys think audio fx of any custom rom fails to deliver good output..?
audio fx is unnecessary without dirac audio service..audio fx is junk...dirac audio service needed..vanilla is always good when it is ice cream.

Arise System can be flashed with ported Dirac service on any custom rom.

Try arise aroma installer 2.94 choice install core system and repair sdcard... Viper4 or Dolby Digital Plus works fine on custom rom :good:

I agree... I've tried dolby but it breaks the music.. makes it **** (my opinion) and viper is okay but not good as stock.. we need dirac

The dac and the amp in this phone is very good you don't need Dirac.You can get perfect quality using audio players like USB audio player pro ,Poweramp etc that use hires audio drivers.i think the only thing that the phone misses in terms of audio is a line out mode to get bitperfect audio out if you want to use external amp

AudioFX in lineageos is doing very good job. You can also try ViperFX and configure it to your preference.

What kind of headphones do you use? The mi headphones in the Dirac profiles maybe get better audio quality. I am not against Dirac in my meizu mx4 pro that I still own (I use it as media player)It has profile for my ie8 also. I would say mi a1 sound quality is on the same level as mx4 pro .I even tested Dirac on my old iPhone 4s with Dirac player that supports apple headphones . But in general mi headphones and apple's are not very good .

Yuuup agreed.. i vote; Dirac for cusrom

what is dirac is exactly?(haven't tested custom ROM, so don't know difference)
I use viper4Android in stock though. Does that disable dirac?
Any interface of dirac? or can be checked through audio quality?

I am not a basshead too I listen to heavy metal ,hard rock I use ie8 and ie80 as portable headphones because of the good soundstage they have .at home I use hd600 . Surprisingly the mi a1 drives it quite well I think ,but I prefer my mx4 pro with fiio a5 or e12 .

ok. Understood about dirac.
But how to know if its processing or not. Does it have interface like dolby?
i see 1 apk with dirac name but no shortcut to open it or know if its working

its background service only......no interface....but outperforms dolby or viper easily.... awesome detailed audio by dirac..must need a port this background service to custom roms.

Thats the Single Reason I left Custom ROMs,and reinstalled Stock. Dolby Atmos/Viper Trust me I dont like Personally ,don't know why the entire forum chased behind two applications ,God knows. Its my personal experience; opinion may vary person to person due to hearing/effect/choices. Currently I'm using stock with Poweramp+ Fiio Ex1 2nd gen headphone ..within 4.5k rs it produces boom sounds. High,mid everything is perfect also sound quality is much more with that price range. With Mi A1; I always advice people be on Stock ROM and buy a good quality of Headphone ...u do not need any kind of mods like viper/dolby/ainur etc...all of them are useless and tried before almost every custom ROMs.

Latest Pixel Experience (Extended and Official) both have Dirac built in now.

Internal Speaker Sound with Stock Rom and Lineage OS 15.1

I have two Le Pro 3 phones here, one has Lineage OS 15.1 and the other one is out of the box with stock rom. So it is very easy for me to test the sound for both roms at the same time.
I know already that stock rom offers the best audio quality with the built in internal spakers. Stock rom offers fuller and richer sound with also more bass with the internal speakers. There is no chance to have similar sound with the internal speakers using a custom rom without using any audio mods like dolby atmos or viper.
But even using these sound mods I was not able to tune the sound of the speakers similar to stock sound.
I made some longer sound tests with both phones and found that there is one big difference between stock and custom rom:
As the phone has Stereo speakers (upper one and lower one), the eqalization of both speakers is totally different with stock. While the upper speaker offers much more mid-range frequencies and nearly no highs the lower one is giving much more bass and high frequencies but nearly no mids. This effect is present with and without activated dolby atmos in stock rom.
So it seems to me that the stock rom uses different settings for left (upper) and right (lower) speakers. With headphones, both channels offer same sound, of course.
Using Lineage OS 15.1 without any sound mod, both speakers offer very similar sound characteristic. I am not able to hear different equalization between upper and lower speaker. The upper one has the same amount of highs, mids and lows like the lower one.
By using dolby atmos or viper, the sound quality improves impressingly but this effects both speakers in the same way.
Maybe becouse of this difference there is no chance to have the same sound characteristic with the speakers like in stock rom.
And maybe this info could help someone to imrove speaker-sound with lineage?

Hi @walking-desaster , maybe you can give the MIUI Ares ROMs a try and compare the sound quality.
This ROM are based on a clone of the X720 (Cool Changer S1 with JUI ROM) and should use similar or updated drivers with Nougat and MIUI 9 on top.
The ROM is posted both on 4PDA and by @tsongming in his Megadrive.
I am not sure why the version posted by Alex_Agir is different from Tsongmings megadrive, maybe he can explain.
Would be interesting to learn your experience.

There is no difference between the Rom Alex_Agir and the one on my Megadrive and I gave him credit.
I posted the file on the megadrive and will soon add it to AFH as well. Just to make it easier to get to. Alot of people use browser that do not translate sites as 4PDA very well. Plus, the Megadrive link includes additional addon, to enhance the MIUI Ares ROM, and to make installation quicker for someone new to Miui.
Like @walking-desaster, I am a big fan of audio.
In fact for me, as a hobbyist recording musician, its usually the most important aspect of my phone. But, I too have multiple Leeco's ( four) so its easy to tryout everything. Plus, I still have my old iPhone, which I use like an iPod for my car.
I agree that stock EUI sound is far superior, and modded EUI's out there seem to be just short of the stellar sound offered by stock. but its close. My issue with stock is that its using marshmallow, which I can't stand.
The Miui Ares rom has the best sound quality of any Rom that I have used since stock. To go on Stock sounds better with Dolby and custom Roms sound better with Dolby. Both sound better with Viper.
Viper is better than Dolby because it has all of the same tools. such as EQ and compression but takes it a step further with the option of being able to add profiles. The profiles include packets of .irs files. Which are convolution reverb impulses ( which are actual acoustic measurements of rooms or speakers) these convolution files allow you to simulate the sounds of room reverb and speaker acoustics. They are similar the impulse responses used in electric guitar amps and headphone emulators.
You can download profiles from my Google drive: https://drive.google.com/open?id=1KtNtBOw1Hj7Rw4OVT2wWdE1ujDAZgo9x
or better yet use these instead
Use the profiles from my drive but use impulse files from sites such as these : https://forum.xda-developers.com/showthread.php?t=2372750
Note, you have to manually add the profiles here: storage/Viper4Android/
BTW, were you aware the Leeco CDLA headphones has a DAC chip and use Dupont speakers?

Best ROMs for audio or stock is good help guys

Hey guys hope your zte axon 7 is still rocking ,well I am using my axon 7 for last 3 year and after a battery replacement it's now as good as new never tried custom ROMs coz of audio performance but now I want to try new ROMs for speed but can't compromise with audio quality can any one help me out choosing rit custom ROMs .thanx in advance

I don't know if there is a huge difference in sound between custom roms.
Mostly, it depends on equalizer like Dolby Atmos, V4A, JamesDSP, DTS:X etc.
But, there's a catch in custom rom, they use high quality dac on headphone and you can't switch it back to standard dac. I have one pair of headphone which sounds a little bit worse on High Quality mode than on Standard Quality. Don't know why and I really don't care that much.
Personally, I prefer Viper4Android to Dolby Atmos, due to many options in V4A, which let you fit - let's just say - to your sound preference.
I only miss surround virtualization from Dolby Atmos for movies.
I tried several Surround IRS but didn't found anything worth.
Using unofficial Lineage OS 15.1 (from Unjustified Dev), Bladder Kernel with Viper4Android 2.6.0.5 (using this version due to conflict between Selinux Enforced and Convolver).
Speaker Optimization sounds pretty bad, I recommend to try some of IRS for Convolver.
That one below, sounds pretty, it even gives nice bass but it didn't work on V4A 2.7.0.0 and doesn't sound same on JamesDSP like on older V4A.
Edit: Just be aware of volume, some of IRS may be louder than original volume and may damage your speakers.
