I'm building a new ROM for my new Xperia Z right now mainly for even better audio quality. However, it'll take a while as I plan to try rebuilding audio driver library file for lower latency. Right now I'm on vacation staying at my parents' house so I decided to build this sound mod for Samsung WM8994 devices instead since I have good chance to reunite with all of them right now.
FidelityXAudio is based from PureXAudio for Xperia Z/ZL made by ZeroInfinity. I asked him for permission to derive his works with mine for all-in-one sound mod I plan to release for various devices that support Alsa driver. For this first release, it'll support Nexus S, Galaxy S, Galaxy Tab and Galaxy Tab 10.1 and all variants. Installing this mod will give you the following features below.
Features:
Rooted & Busyboxed - This will replace current root and Busybox with latest SuperSu and Busybox. Since most root access for Xperia Z I tested are so unreliable getting bootloop after mounting system rw, I'll force better ones in this package to avoid that problem.
exFAT support - If you're using Android JellyBean ROM but still not have exFAT support yet, this may help you getting one. It works for Xperia Z/ZL but haven't tested for others yet.
init.d support - This isn't cheap recovery flash init.d script. It'll execute init.d script with root access from hardware boot script level so it works far better than conventional ones for locked bootloader running stock kernel.
Xperia Fidelity script - It's ultimate sound quality mod script I've been developing for years. Not only get you better sound reproduction but also make your system smoother as well.
PureXAudio engine - As FidelityXAudio is based on PureXAudio mod, most PureXAudio features are availble except audio effects and specific sound card stuff. I may consider adding them back later though.
Low latency tweaks - My tweaks inside PureXAudio for lower latency Alsa configuration. Not sure how much of it works though as real measured hardware latency won't change without modifying driver.
Mastering 64-bit quantization - The most accurate 64-bit floating point quantization in Android. I usually end it with 32-bit integer mode but this sounds better for crazy upsampling level.
DSD128 audio processing at 5.6MHz - This will give you high resolution audio simulation. The real sampling rate will still be 44.1KHz but with 128x upsampling for audio processing before downmixing is really something.
Fidelity nVIDIA audio configuration - Optimized for more direct bitstream with lower latency. Only for Tegra devices though.
Removed DSPManager for more solid audio performance - This mod breaks DSPManager in CM ROM so no point in keeping it and you probably won't need it anyway after hearing sound with this mod.
Download: PureXAudio v1
You can't flash this on other devices as it can break audio with incompatible sound card configuration. I tested on my Nexus S, Galaxy S, Galaxy Tab and Galaxy Tab 10.1 and they're all working fine. Guess not many people still use them nowadays but they're great ones for sound quality wise. I'll update again for APQ8064 based devices in next version after releasing new Xperia Z ROM.
Installing this over cm10.1 caused my USB storage to switch to sdcard0 and my SD to go to sdcard1. I couldn't switch them back with build.prop and ended up reflashing cm10.1
Sent from my Galaxy Player 5.0 running Android 4.2.2 Jellybean
Same issue.
Is this in the wrong device section?
Probably caused by exFAT support patch for JB devices.
also guys don't forget that this sound mod is for the devices with a wm8994 sound chip which only the 4.0 has so don't come complain if it's not working.

Find "vold.fstab." open it, and change "/mnt/sdcard/sdcard1" to "/mnt/sdcard/sdcard0."
Why is this in "Galaxy Player 4.0, 5.0 Android Development"?
Will it work on a galaxy player?

Please refer to zaclimon's excellent all-in-one
Many people will be attracted to this device because of the sound quality delivered by the Wolfson Microelectronics WM8994 DAC. However the full potential can only be released by installing supercurio's Voodoo Sound (Google Play)
This requires root and a suitable kernel. The custom kernels referenced in the guide are all based on -SteveS-'s and will do the job.
So now to choose a ROM...
For some reason all the stock based ROM's appear to include the Beats Audio MOD (Introduced by klin1344 in R2.1 of his Klassic ROM and included by all followers). Some claim this improves the sound quality, but I would strongly disagree. Unfortunately it appears to be hard/impossible to remove.
The SGS ports have issues with camera and bluetoth and the non-stock based ROMs have their own issues which may put you off.
So that leaves us with... Stock
Don't worry, all is not lost, with a few tweaks it will work well.
First use the all-in-one to install a custom kernel and root your device.
Required apps
Voodoo Sound
Rockbox or PowerAmp
Total Commander (or any other root explorer)
Your launcher of choice (ADW free works well for me)
All your favourite apps...
Remove Music 1.1.1 and any other stock apps that you don't want.
Copy .nomedia to your music folder (for me the root of my external sd card) to avoid all your album art appearing in gallery and to make startup quicker and save your battery.
Any other alterations will be to personal taste, but you will have a great sounding player with superb battery life and everything works...

You can download the build 3.5 of ICS for the 4.0 It includes voodoo kernel module so no worries. The only problem for audiophiles though is no deep sleep and maybe lags (because of no openGL).

Thanks, I will give it a try. Lack of deep sleep is not such a huge issue - attempting to deep sleep and crashing is
A fully functioning CM9 would be great

Most ROMs have Voodoo, and you can download it anyway. What you want to check is the kernel Scheduler used by default. I've found that under some load I had noise and, rarely, lags when I was heavily multi-tasking.
I don't think there's anything that can really affect the sound quality. Has anyway seen if Samy had patched the sound driver in their stock kernel for some tweak?
actually if you read through the change log there are several versions of klins and even one or 2 of Han's ROM's where they removed beats audio because of how it broke other things, till they got a newer version of beats that didn't break it anymore.

Agreed, I jumped the gun a bit early with the ethereal Rom as i simply was flashing rom over one another and come to find out some files stayed with the conversions. With a fresh wipe and back to stock, I installed ethereal and haven't looked back - an excellent rom that eats alot less ram compared to Icy Fusion (of course nothing really touches stock in regards to ram until the ics rom comes to full fruitation). Beats doesn't even activate until you grab the driver app (which I haven't done). Using the voodoo control app instead, all is well with great battery life too!
Note :1. I'm just sharing the work of the XDA Member c.innovation.This app is a compilation of some of the audio tweaks used in the custom roms by the devs.This app was tested on Galaxy Y GT-S5360 running GingerDX (CM7) and Hyperion 8 Final build.
2.Please remove the DSP Manager before installing this.
What's Raccoon Audio?
Raccoon audio is audio optimization applications in the audio device is a modification and combination of multiple applications with the interface of the sound enhancer noozxoide EIZO-rewire ™ PRO simplified and modified to incorporate some engine sound enhancers like beats audio, dsp manager, SoundFX, dolby and some other.
What distinguishes Raccoon Audio sound enhancer with other applications?
-The difference is more RA refers to the optimization of the sound on your android device and maintain the stability of the supporting hardware audio device.
-Besides installing the RA in quite easily.
-Install RA without using CWM,
-Install RA without a push into the system,
-RA can run on any device that unroot,
-RA is not at risk of brick or bootloop,
-RA is more compatible with almost all ROMs and android devices, but it is also compatible with most music players and when you have an android device other sound enhancer, RA tend to be more friendly
-Effects of raccoon audio not only do you feel when playing on the music player, but the effects can be felt when you play back audio in the file browser that supports audio player, the youtube app, the internet browser
In any android version can be active RA?
Starting from gingerbread to jelly bean, for froyo RA can not run.
What privileges audio raccoon?
Raccoon audio smoother and more compatible with the music player or audio player such as youtube, browser and others. Besides the interface more attractive (for ics). Using the engine of sound enhancer that has been optimized so it is suitable for audio and raccoons can be used universally in different ROMs and devices.
How to use Raccoon Audio?
1.Download Racoon Audio by clicking link below post.
2.Install instruction included.
FAQ (Please read before running raccoon in audio)
Q: RA only smaller?
A: Yes, RA is a combination of several audio enhancer such as I have described above, to our use of noozxoide interface, but we simplify and modification. Our consideration is a small file so for those of you who have a small memory can also be shared in the RA, in addition to that we have some other considerations especially for low device.
Q: Is the RA safe to run?
A: Safe, because of the way RA is relatively easy to install and does not cause brick, bootloop when you install applications such as audio enhancer should use CWM, or push to the system. Besides applications like RA and other articles on tips droid always through testing stages before publication so that readers tips droid safely use our applications and tutorials. RA is also safe from viruses and mallware (tested with some antivirus on your PC and android and declared clear of viruses and mallware)
Q: RA can run smoothly on the android version is it?
A: Our RA test runs smoothly on the stock ROM and some custom ROM from several different devices both vendors (Samsung, LG, Sony, HTC, Hi-Sense) and type. In Gingerbread, ICS and Jelly Bean goes smoothly, but on froyo not work.
Q: After using RA why even a small sound effect almost no change?
A: In addition to RA, running or not depends on the compression of the song, when you use an uncompressed song irregularly, RA can not run optimally.
Q: My RA force close, what's the solution?
A: We minimize these events, some tests we did, but for some applications audio enhancer, I have tried to make the RA is compatible with other sound enhancer, but in some cases RA sometimes can not run smoothly with sound enhancer, if it happens, you should take the solution is please to freeze sound enhancer you have used before.
Q: Is the RA only have an effect on the music player?
A: No, the RA will provide overall audio effect, like on youtube application, browser, file manager that has audio player, ringtones and other (including voice when you call, but only a small effect to reduce noise so that the sound can be heard clearly when your phone, it also depends on your signal and your listener while also mic your speaker and your speakers)
Q: Is the RA can damage hardware audio?
A: RA helps you to optimize the audio hardware and software you. If you do the proper setting in RA, the audio device you will be more durable and optimal than not use RA, but if you are setting up the force in excess, will cause damage to your audio device.
Actually not only RA, but all applications enhancer and music players can damage your audio hardware, if you make the wrong setting volume dimaximalkan example, setting dimaximalkan without tolerance. Without the application of RA or audio enhancer memaximalkan even if you force a continual and regular basis, I can guarantee your hardware will be damaged, but it is less convenient when you hear the organ and can damage your hearing. DWYOR.
Q: How do I set RA is best?
A: For this question I answered "relative", we suggest you to try to do their own personalized settings, and the ability to tune your audio device. If you are confused you can find references on the internet how to set up the equalizer on the right and the best android.
Q: After using RA, why is music to be large or small volume suddenly?
A: Make sure you play good music and not compressed extrem, also make sure the bitrate of the song, make sure your music player and speaker capabilities of your audio device. Also make sure the RA runs and does not crash with audio enhancer you use before you install RA. Setting RA also affects the quality of the sound produced.
If it happens that you take is a solution uncheck audio compression options

Some people can't make viper4android work on the new Lollipop update so I'm doing a simple guide:
Requirements:
-Root
-Busybox
-Custom recovery
Installation:
1.- Deactivate NuPlayer in developer options.
2.- Deactivate any other equalizer.
3.- Set selinux to permissive with an app like this one https://play.google.com/store/apps/details?id=com.mrbimc.selinux&hl=en
4- Install through recovery the zip located below then reboot.
5.- Open viper4android and install the driver you want and then reboot.
6.- Done, enjoy high quality sound.
these are the only versions of audio_effects and audio_policy i found that work with streaming apps. can you elaborate a bit more about them where did you find them or maybe you have an idea what was modified in them in order for streaming audio to work? thanks!
Good job! But how can I increase the power of the speaker, like in KitKat using Mixer app, but in Lollipop?

I use those 2 files from the zip file to make v4a works for poweramp
My previous v4a installation only works on stock music & video player, now works for poweramp and mx player too.
Another note, disabling NUplayer not necessary for me...
Thanks again for this awesome guide :good:
Edit: I found using stock audio_policy.conf is possible to by remove this part:
Deep buffer
deep_buffer {
sampling_rates 44100|48000
channel_masks AUDIO_CHANNEL_OUT_STEREO
formats AUDIO_FORMAT_PCM_16_BIT

Note: removing compress offload not necessary, as stated in dorimanx lp kernel thread. So removing deep buffer part only is enough.

So, i've been having this huge problem on Nexus 7 2013 w\power amp and 5.1.1 cm12.1 and getting convolver and irs files to work properly.
two questions,
are your irs files working?
also, is the audio policy config on this thread flashable or pushable?

No problem with irs & convolver on my D802, both working normally. I don't know for other devices.
The file from op is flashable from recovery. You can try that.
Just for comparison, I use other methods, I installing v4a manually then install the drivers from the app. Imho audio effect config will change when v4a installing driver. Most useful part from this thread for me only the audio policy config that solve my problem make other apps like poweramp work with v4a. Then I found that audio policy config from D802 stock rom can be use too by removing 2 parts. I believe this solution is better because I only lost 2 features from stock rom, not as much as the policy config from op.

Yeah, i flashed the file above and did everything properly, but IRS convolver files aren't exactly being 'used', not all irs files are working properly.
Should i be doing anything to the audio policy config file ? I use power amp too (although it did tell me it was processing under power amp),
IRS is crucial to me because i use my N7 2013 in my car as my in-dash.

I think that's unrelated to the audio policy config thing, this thread already prove the way v4a working for D802. Solved the major problem why v4a only works for stock music & video player.
I suggest you to ask in the v4a main thread or maybe ask the dev that creates your favorite irs that didn't work. I only use 2 irs files & both working normally.
this is kind of off topic but perhaps somebody is experiencing the same. i'm having a weird audio issue on LP which wasn't present on KK in any way and not V4A related.
no matter what the audio source is (playing mp3s or lossless, tons of EQ on or off, YouTube video, game, video, etc) there's a totally random, short sound corruption that sounds like garbled, sped up noise. it's impossible to trace any pattern when and why does it appear and perhaps it's related to radio since it tends to appear more when the signal is switching from Wi-Fi to cellular or cellular signal comes online, etc but not necessarily. i tried to look at the logs and don't see anything suspicious regarding sound there at all.
there's also a theory on other devices forums that Qualcomm's mpdecision is the cause since it always leaves only one core for the sound online and on LP apparently you need more. that doesn't seem right, however, since it does happen when the phone is doing a lot too and not just with the screen off.
any ideas are welcomed.

You can try if the theory was right or wrong by temporary disabling mpdecision. I think the setting is in /mpt/enable file. Change the value from 1 to 0, than compared the results. Don't forget to enable it again by changing the value on that file back to 1. If still no different, I guess the theory was invalid.
doesnt work for me I flashed the zip and then got "viper 4 Android stopped working" on Start, now I cannot install it in the normal way. Every Reboot that "viper 4 Android stopped working" thing comes and idk what to do

after much experimenting i can confirm that the only way to fix that issue is to always keep 2 or more CPU cores online, nothing else solves it at all.
with stock kernel the only option is to disable mpdecision and enable "multicore power saving" and "soc temperature throttle" for further heat control because without mpdecision you'll be keeping all 4 cores online.

obviously using a custom kernel gives way more options to keep those 2 cores online in less destructive manner.
no problems with V4A here, everything works exactly like on KK. like mentioned above the key is to use it as a system app, modify selinux mode and edit audio policies files.
According to xperia z3 users in xperia mobile forums, lollipop update has limited sound enhancements to movie player + walkman app and a few more playstore apps.
This is because the sound enhancement is no longer system-wide compared to kitkat.The 3rd party app developer has to include code to support sound enhancements otherwise you don't use it with third party apps.
Can any lollipop user open subway surfers, then listen to it's song for a bit and turn clearaudio+ off, return to game and see if there's any difference? I want to confirm if it's the same for us Z2 users.
I have done that in subway surfers using kitkat and it did make a difference in sound.
Bumping thread, I just need someone who's using lollipop to confirm if clearaudio+ or loudness equalazation works in subway surfers. :fingers-crossed:
This is important for me as it confirms that lollipop still enhances 3rd party apps' sounds.
Thanks in advance
I don't particularly have the game, so I can't help with confirming your query.
But I have tried it for the youtube app and found that the sound enhancement does not work. I also tried toggling clearaudio+ on and off and adjusting the equalizer while soundcloud was playing a song in the background and nothing was happening. From this I think that there is no sound enhancement present in 3rd party apps. It was not like this before when I still had kitkat.
Sorry if this doesn't help.

I requested info on that particular game because some users said enhancements didn't work for youtube in KK anyway and well it's a commonly played game :silly:
It seems like that was a false information.Enhancements work for me on youtube (on kitkat now) and appereantly it doesn't work on lollipop.
Thank you for confirming
Guess I won't be updating to lollipop until sony changes their mind on this or something worthy comes out (better camera software perhaps)

Here are more informations about this issue:
https://code.google.com/p/android/issues/detail?id=22726
As the sony support stated this is not removed by sony its removed by android. You can call it stupid and it is indeed, but it won't change this in lollipop. There is also no plan to change this in any next releases of android.
So here is the intent every application have to implement to use a system wide equalizer:
http://developer.android.com/reference/android/media/audiofx/AudioEffect.html#ACTION_OPEN_AUDIO_EFFECT_CONTROL_SESSION
you see its not a mess for a developer of a media player to use the system equalizer. This feature was available since Android 2.3 Gingerbread, enough time for everyone.
Hello there,
I have recently switched to an Oppo A37f. I downgraded it and managed to root it. Viper 4 android is one of the favorite applications I use so I went ahead and installed it. However, despite installing all the V4A drivers and stuff, i feel no difference in the audio quality. The system comes with default Dirac HD which doesn't even come close to how good V4A performs. I would like to have someone help me with Viper for Android soonest, as it is one of the main things I need on any phone.
Thanks !
PS:
-Does this have to do something with color os ? I've worked on MIUI, stock android and never had this issue.
-Apart from viper for android i've used non root apps like Bass EQ, Bass Bosster, V4A(on play store) from the play store but none of them make any change to the audio no matter how much I mess around with the values on the EQ.
Is V4A Status: Normal and Processing: Yes?
Have you frozen your ROMs default EQ?
