Hello, I am studiominal from Korea. I’m going to explain what ‘Voodoo sound by supercurio’, and ‘Galaxy Tuner by dowkim10’ actually are, plus how to use these solutions to brighten your music life for users using Galaxy S as their MP3 playback device. Please be sure that I’m not an expert in this area, but I managed to get pieces of information regarding sound stuff, so I’d like your patience and also welcome your criticism (plus my English).
What are ‘Voodoo sound’ and ‘Galaxy Tuner’?
First of all, two of them both have the same goal to improve the sound quality of Galaxy S by tuning some systematic parameters within Wolfson WM8994 chip. Before describing differences between them, I’d like you to have a look at this.
1/ Mic sensitivity
2/ True line-out
3/ Headphone amplifier gain
4/ 5-band Hardware Parametric EQ
5/ Radio Noise
6/ iPhone headset support
7/ Call through headphones
8/ General sound quality
9/ Bluetooth gain & A2DP streaming issues
10/ Specialization effect for headphones & Crossfeed
11/ Multi-track recording support and VOIP fixes
Yes. These are the small objectives that supercurio mentioned which will be available on final Voodoo sound solution. It seems that overall progress doesn’t go exactly in the order of the list above, but I think it’s definitely going in the right way. As most of you might have noticed, the first release of voodoo sound has feature #3 and #5, and #1 and #8 are expected to be coming in the next version.
Let’s take another look at Galaxy Tuner by dowkim10 then. In this app, feature #4 and #10 are available, which means you can alter the native equalizer as you wish. (The most-wanted feature for me yay ) This app, however, doesn’t have full features of * parametric EQ because the developer didn’t have the proper datasheet for WM8994. Nothing to worry though, a full parametric EQ will be available in supercurio’s release. So today I’m going to let you know how to set your EQ using Galaxy Tuner. What if supercurio releases it so fast? Hmm.. let me think about it later then
* What is Parametric EQ?
Equalizers in poweramp, or default Samsung music player are called band Equalizers. It has several bars with fixed frequencies tagged, and the only control we can have is called ‘gain’, which we can alter in the direction of plus or minus. Parametric EQ is literally an EQ with several parameters: Center frequency, Bandwidth(Q-factor), and Gain.

}
Center frequency : The center of frequency you would like to emphasize or diminish. By adding some gains, you’ll see a peak formed at the center frequency. Of course you can change this center frequency in parametric EQ in an allowed range.
Bandwidth(Q-factor) : There comes a slope when you alter the gain of a band, and this parameter determines whether the slope should be steep or gentle.
‘Gain’ is just what you know already. (Degree to which a band is emphasized or diminished)
It is said that the more number of bands, the better the EQ is. With 5-band parametric EQ, however, I don’t think that’s always true. You can make a bunch of graphs by changing 3 parameters of each band. OK. These were for people who might not know what the parametric EQ is, and let’s get the real deal started.
Prerequisites
1. You must have ‘voodoo sound kernel’ and ‘voodoo app’ installed.
2. Your device must be rooted.
3. You also must have ‘Galaxy Tuner’ installed.
How to set Voodoo sound : Headphone Amplifier Analog Gain
Underneath is a screenshot of VoodoApp by supercurio. As many of you may have noticed, all the settings are reset upon rebooting. So the bar you see now is the default gain of headphone amplifier on Galaxy S.
You don’t have to think for a single second in this dialog, which means dragging it to the right means you’ll get louder volume, and left will result in quieter volume. I think I read a tip from supercurio and would like to let you know what that was by announcing in this post. (Cannot exactly remember where your tip was at, sorry supercurio )
1. Lower your amplification level in VoodooApp below the default level.
2. Maximize the volume bar in your music player (Android system)
3. Finally change the amplification level in VoodooApp again to fit your ears.
“By performing these procedures, you’ll get both lower noise and satisfactory volume.” I think this is similar to what supercurio said. However, there’s one major caution when using this technique I think, which might blow your ears. PLEASE KEEP IN MIND THAT HARDWARE AMPLIFICATION LEVEL WILL BE RESET WHEN THE DEVICE IS REBOOTED AND MEDIA VOLUME WILL NOT. Maybe there will be a solution coming automatically when ‘set on boot’ option becomes available.
So I won’t recommend this method for all of you, but only a few who are using receivers with low impedance(16ohms) or receivers of high sensitivity. This is because not only the volume but also the noise level will increase by increasing analog amplification gain. Of course, the SNR is very good for a phone in this class, and you might not notice a big difference of noise level though you have altered it a bit to the right. And for those who are using receivers with 32 ohms of impedance or higher, it’ll be of no problem.
In addition, I’m one of those who think that quantitative ways won’t always work, so I’d recommend you alter it without any annoying figures or formula
How to set Galaxy Tuner : Sound (3D, HW EQ)
Finally we’re here. You can see 6 bars after you launch Galaxy Tuner. Let me start with the one in the top, the 3D effecter. By turning this feature on you will feel as if the stereo sound is expanded wide. Be sure that if you set it too high, it’ll result in a lot of distortion. Personally I set it at the maximum of 7.
5 bars are the bands for hardware equalization(B1~B5), each of which has a 100, 300, 875, 2400, and 6900 label. These correspond to the notion of center frequency I mentioned above. (100Hz and 6900Hz are called cut-off frequencies, not center frequencies)
The picture above is describing the results I recently measured with RMAA with ALC889A codec. (I’ve got a PCI one, but there seems to be a problem especially in line-in jack) Here you can see each graph drawn when each band was altered by 3 dB. See the peaks around 20Hz, 300Hz, 800Hz, 2500Hz, and 17000Hz? And some of you (including me in the past) might notice that it’s different from what is displayed in the Galaxy Tuner application. (like “What happened to 100Hz and 6900Hz?!”) I thought the datasheet was wrong, but I came to know that I was wrong. (How shame )
Now that we have an idea how the graph is altered when using this app, we want to know how to set it! Seeing many people who love listening to music, I thought some of them prefer the FLAT graph and others prefer their own tastes. Of course I’m one of the latter, so that’s why I’m writing this. It is said that most men can sound from 100Hz up to around 8000Hz, and women/children 200~9000Hz. Instruments, of course, have much wider a range of frequency bandwidth. Looking at the graph I posted right above, the peak for B1 forms around 20Hz, which is very hard to hear for a human, and the shape is so gradual that it might have a negative effect on other frequency bands. I think 50~60Hz will be just fine for people who seek for dense and powerful bass. (And this will come true with supercurio’s awesome next release I suppose)
Personally I love strong deep bass and emphasis on string instruments, which leads to a V-shaped eq setting. So mine is like +4, 0, +1, +1, +3 from B1 with Sony EX-600 earphone. The results are shown in the pic right up there (the one in the bottom, green)
~130Hz : MEGA BOOST!
~5000Hz : nothing special
5000Hz~ : Boost
That’s what I’ve done for my taste. Of course you might have your own tastes that might be different from mine. For example, if you wish to hear the vocal more clearly, just alter B2, B3, and B4 and you’ll notice the voices got boost. And for special cases like Triple fi used with Galaxy S which is known to be a mismatch because of attenuation in high frequencies, Galaxy Tuner will do the work
Thanks to ‘Voodoo sound’ and ‘Galaxy Tuner’ anyway, I came to convince that every user of galaxy S has a potentially good MP3 player. For those who seek for frequency bandwidth of other instruments, please refer to the address below.

Galaxy Tuner *unlocked version for GT-I9000* by dowkim10

Thanks for this big explanation...
Unfortunately I never got Galaxy Tuner to run on my phone, it seems to think my phone is not a galaxy s... (Not even with stock roms).

Here's the URL you need now. The unlocked galaxy tuner!
Both apps can really use apply settings on boot!
Does it work for GT I9000 europeen version?
Yes! It is an unlocked version so it should work on GT-I9000. Remember that I'm not the dev. All thanks to dowkim10, I had a chance to experience how superbly the sound can change so early.
Hi studiominal
Thank you for sharing this knowledge!
I would add an important note about the EQ usage.
For correction purpose and best result, an equalizer is supposed to be used by attenuating some frequencies and not boosting other.
Actually, Galaxy Tuner EQ implementation miss dynamic range compression and you can easily create distortions, this is why it's even more useful to correct by reducing and not increasing gains
Absolutely hehe. I don't know why, but I just love massive bass Always looking forward to your awesome work! I heard you're going for an interview. Good luck!
It seems very useful article.
but, It is difficult to understand
I am novice about sound.
Excellent guide! Thanks for explaining thoroughly. Lol dowkim10 is just being humble.
hello freakfingers12
The first user of my app except korean.
but, It is true that I am novice.
Thank you.
As I wrote in the original Voodoo Sound Thread,
its easy to hardcode the amplifier level all you need is root explorer.
Just write this: " echo 62 > /sys/devices/virtual/misc/voodoo_sound/headphone_amplifier_level" (you can insert any value from 1 to 62 for max gain) into one of the init scripts at /etc/init.d.
@Supercurio: Maybe you could use some of Xan's code (he has made the source of his voltage control app public) to implement a
"apply settings on boot" feature
I heard from lot of people that the sound quality is a big inprovement
I have all requirements exept of galaxy tuner i am going to try it on and report back here

Why isnt galaxy tuner supported in darky rom. 8.0? Im not able to launch the app
Sent from my GT-I9000 using Tapatalk
galaxy tuner has 2 dependency to run.
(but, basically, there is no dependency about custom rom)
check below
1. froyo(kernel 2.6.32.9) 2. rooted phone.
I have managed to get it running but when listening to 'tunes' and the notification goes off, the eq is reset to flat. On going back into the app, my settings are still there and all I have to do is hit apply.
Is this a bug or am I missing something?

HI!
Does anybody know about a Guitar Tuner software (a real tuner, not just playing the notes) working properly on Artemis? I tried a few on my device (actually an SPV650) and none seems to work. The note is never recognized. Thanks
I use Frequency Tuner:
http://www.frequencytuner.solcon.nl/
You have the option of guitar or piano view and has more options than every other tuner out there.
-Mc
I've tried frequency tuner on a couple of machines, now. can't get it to tune at all. it just jumps all over the place... even in a silent room. tried playing with all th settings but just can't get it to recognise the correct notes. have given up now.
is it just me?
I use it on EVERYthing I have.
Maybe you need to adjust the "trigger" at the bottom of the screen?
I'm currently running it on my Wizard, Kaiser, and Touch Pro. I use it a lot actually...
-Mc
After some testing (I originally started this thread) I managed to have decent results on my Artemis using both "4Pockets Guitar Tuner" and "enable Tuner". Both are shareware. In my opinion, both have the same problems:
- Practically no way to tune the low E string.
- No way to use "automatic detection" of the played string. The measured frequency is really not stable so the Tuner almost never makes the right guess. Yet, in manual mode is usable.
- The measured frequency flips up and down a lot, but after a while you get used to it and you manage to use it.
-No way to use it in a noisy place.
I still cannot say if it works better with or without the AGC microphone enabled or not. Depending on that you might want to adjust the distance between the phone and the guitar.
After some testing I took my old tuner and tried... the process it's just so much easier and quick that I really cannot say I don't need it anymore. Yet, if I don't have it with me I can do something with the Artemis.
The following also look quite good, although I have not tried them:
Auto Tuner:
http://www.4pockets.com/product_info.php?p=52
PhonTuner:
http://www.phonature.com:8092/home/products_mpApp_PhonTuner.htm
Hope this helps.

Is the one I was talking about. It's ok. There are a few version around, all are quite the same.

frequency tuner works
On my HTC touch HD, the free frequency tuner works really good!
http://www.frequencytuner.solcon.nl/index.html
It takes about 5 seconds to get a frequency and tone, but that is very all right for tuning instruments.
I am happy with it, thanks xda!
which version did you use? sorry abit noob here. which one should iget for diamond touch?
Hi, after doing a similar app for the i9300 and its scoobydoo sound voodoo derivate, i modified my app to be compatible with the i9000 and voodoo sound.
It is so far feature complete and all is working, if you have any suggestions, feel free to ask.
Attention, LaboDJ Slim gapps are not supported, this package is missing something that prevents that VoodooEQ can be installed

Re: [APP] Voodoocontrol - control the voodoo sound hardware equalizer
As far as I know sgs has the capability of stereo but at least my phone has one speaker, so it is not stereo, I can see the the difference with the earphones or external speaker,correct me if I am wrong. also my phone has low sound level, you must be close to it to hear music.
For your app now, From first use i notice a small problem with analog gain slider. I used earphones to hear radio and i had no sound, i realise that the voodoo headphone amplifier was too low,i increase it but i had to decrease in this app the analog gain. I notice that had delay to increase/decrease and the slider need to be moved very little or slow in order not be very high or very low,looks as if scaling is wrong. Shall try it later with speakers. I hope I was somehow clear.
Thank you, this app is great, today I enjoyed music (earphones)

In this Datasheet i found that the EQ center frequencies and bandwidths are fixed in default mode, but can be programmed in reTune mode. Don't know if you are working that low level oriented or if you leave this to voodoo sound, meaning you would have to find out how voodoo configures the eq mode.
Furthermore a graphic display of the eq settings would be nice, don't know if you are familiar with the terms.
Let me know if i can help you with anything!
Anyway thanks for this app, it's very good as it is now, the parametric eq is just a nice-to-have
EDIT:
You can also see in the data sheet that as expected band 1 (low) and band 5 (high) are shelf-EQ's, while the mid bands have bell characteristics.
Very interesting seems to be that for negative gain values the bandwidth of the EQ's is big times smaller than for positive gains, making negative gain settings more a cut for specific frequencies (the currently fixed center frequencies) and therefore not very usable.
The further i read the datasheet the more sure I am that filter bandwidths are not programmable.
AW: [APP] Voodoocontrol - control the voodoo sound hardware equalizer
I think there is a way, looks like voodoo sound has an interface for that, check the file /sys/class/misc/voodoo_sound/headphone_eq_values it contains 3 values for each band and some hex values:
Code:
1 A 0x0FE3
1 B 0x0403
1 PG 0x0074

We just need to find out how this works and we can configure it like we do with all other values...

Which of the values do you change with your app at the moment?
This value is gain then.
Seems the shelf EQ's 1&5 have one parameter less.
EDIT: Gain value is 5 bits only according to data sheet, how do you handle this?
Or better question: how does voodoo handle this? Is the given 16 bit value scaled?
EDIT2: Would be nice to see the actual gain value (-12dB...0...12dB in 1 dB steps), maybe on the right side of the seekbar.
Also the current center frequencies would be nice to know for the users (1: 100Hz, 2: 300Hz, 3:875Hz, 4: 2.4kHz, 5: 6.9kHz) according to data sheet

After converting the hex values to decimal in excel i think that PG values are the center frequencies, most likely simply in hex.
I try to modify them manually and see what happens.

So, I've been looking into the well known issue of excessive audio gain in CyanogenMod. Reading the mixer_paths.xml files for both CM and Sense doesn't show a noticeable difference in volume. Yet the sense ROM only crackles on the highest volume, and the CM ROM had a much more noticeable crackle, even at lower volumes. From what I was told to understand, the CM kernel uses a volume gain hack that has existed since the Gingerbread days, that the HTC kernel does not use. I think disabling this hack, along with the fact that, unlike BoomSound, DPS manager defaults to a flat EQ, would produce a sound similar to that of what the M8 would sound like had it shipped without BoomSound. I think this would produce no crackle as long as DSP manager is untouched. If possible, I'd like to see a CM kernel made that is unchanged, with the exception of removing whatever code is used to increase the gain. Or, if the gain is a hardcoded setting and not a kernel hack, reducing it to stock (or slightly lower, because some users experience crackling on even a stock ROM) levels. I think a reduced gain kernel, coupled with CM11, would produce the best possible HTC One.

Yes that is the point I don't have the folder you mentioned. All audio configurations are controlled by mixer_paths.xml
I'm running CM11 right now.
Does anyone have the config changes need for the STOCK 4.2.1 G Pro? (to increase speaker volume).

mohsin.android, I wish you and other people would be UP FRONT and State what version Android Stock ( + Version ) or Cyanogenmod ( + Version ) or Other , this post applies to !
Many People are doing things which cause wasted time and frustration for others ( posting in wrong forums, needlessly quoting prior posts). I personally was brought here by someone incorrectly posting G2 config info in a G forum.

If you read the OP, then you will see for WHAT version this mod is.
Very cool thanks for finding this. I plan to use.
Any idea how to boost microphone volume, especially when phone is on speakerphone? For some reason it must be set low because nobody can hear me unless I hold the phone next to my mouth.
I tried few setting in mixer_paths.xml to change microphone volume but didn't succeeded.
I'll update if I find any method..
Thanks
any idea on where is the bluetooth media path (i.e play music with bluetooth) is located ??
Awesome , I did it ! Thanks man , you're great !

Hello xda community
Today I am sharing my knowledge related to the sound modding in android as a way of saying thank you for all the support I received from the xda members in the forums
About myself: I have been working as professional DJ and sound engineer for serious gigs since 15 years.
Goals: This is a general guide to help you understand the fundamentals of sound output in android and how to edit it, then you have to do some research specific to your phone/tablet or experiment on your sound file to have the desired levels. Theorically, this applies to any android phone or tablet, although the values to input will differ from one device to another and from one manufacturer to another. Here I am describing how I boosted the sound in my Xperia Z1, so be aware that applying the same values on a different phone might get different results.
Why I wrote this: Most of the sound mods will not work if you have a different android version than the one of the modder because the architecture of the sound paths might differ from one android version to another, even if it's exactly the same device, so it's vital to be able to boost your sound on your own if all the mods didn't work for you or no mod exists for your device. Sometimes also, a modder wishes to create a sound boost mod but doesn't know how to get the maximum loudness without losing quality. This will no more happen if you read and understand this guide
Note: I am not responsible if you cause any damage to your device or your sound stops working, you are the only one responsible for what you do with what is described in this guide.
Requirements: rooted phone, file explorer and note editor (I use Es File Explorer as it has both)
I wrote this guide to clarify what needs to be edited to get a louder sound without losing quality, so here are the facts:
To get started, use a file explorer and navigate to /system/etc and locate a file named mixer_paths.XML
I recommend that you make a copy of this file in case you need to restore it later if you get undesirable results with your experiements.
Open it using a note editor and locate the sections of your interest, usually there is a title for each section with the values coming right under it, e.g "Headset volume" or "microphone volume"
Starting from here you will have to find out the values specific to your device either by finding them in the forums (if you are lucky) or experimenting by editing the values I am about to explain.
HPH (amplifier/electric output) vs RX (digital/signal):
HPH: Basically, the best way to get a volume boost without decreasing the sound quality is to increase the amount of electric power that your device outputs, this will have the effect of feeding your headphones with more power which will generate more acoustic pressure (DeciBels/db) without degrading the quality (provided you didn't reach the limits of your headset). To do this, just set your HPHR and HPHL to as high as your device allows.
Rx: This is somehow the input signal of your sound, increasing this value will boost the source signal which will create distortion and saturation, this will result in a sound that will feel louder because of the generated compression, but the cost is a loss in dynamics and quality, the loss is proportional to the increase in the signal. In other words, increasing the RX value will distort and saturate the sound, you will have a louder but poor sound quality with a huge loss of bass and a flat sound, with the possibility that this will fry/damage your phone sound card and/or headphones at high volumes because of the saturation generating constant electric current which could overheat the wires/transistors beyond what they were designed to take. Add to this a higher risk to internal ear damages.
My advice is to start increasing the HPH value to the highest possible value first, save the file, reboot and see if the sound boost is high enough for you. If that was not loud enough, then try increasing the RX value by +3, save, restart and try again.
Facts: The loudness doubles at every +3 db, which means RX 85 should be 2 times louder than RX 82
Conclusion: The first step to boosting your sound is to increase the HPHR and HPHL. If more loudness is needed, increase the RX value gradually by +2 or +3 until you reach the desired loudness (try to find a good balance, I wouldn't recommend going more than +3 beyond your current RX value). Keep in mind that too much increase in RX will make you lose bass and sound quality, at that point don't expect the equalizer (EQ) of your music player to give you more bass or improve your sound quality because you have saturated/damaged the sound at its origins.
I hope this will help you set your sound at the desired levels without damaging your sound quality or devices or headphones or ears.
Note: I am using these settings on my Xperia Z1 with my Sony MH1C headset, these values should work for the Xperia Z1 Compact because it has a similar hardware. Theorically, this guide is universal and can be adapted to work with any android device, the values in mixer_paths.xml might be different on other devices but the boosting principle is the same.
More infos:
HPHR = Right output
HPHL = Left output
People with impaired hearing can set up these 2 values differently. E.g: HPH? 20 should be for the weak ear, set the value for the strong ear at anything below 20 until you reach the balance between the 2 ears.
Edit for some CyanogenMod Based ROMs: On my S4 mini running a Resurrection Remix Marshmallow ROM, which is based on CM, I didn't find the mixer_paths.xml file, instead I found a file which contained similar settings for the sound.
The file is named snd_soc_msm_2x and is situated in : system/etc/snd_soc_msm

ALL THANKS AND CREDITS GO TO THE ONE AND ONLY KTOONSEZ FOR HIS AWESOME KERNEL AND GIVING ME THE OPPORTUNITY TO PROVIDE THESE BUILDS.
Welcome!
I am in no way affiliated with Ktoonsez or his work. I’m just a simple member of the XDA community who happens to be a huge supporter of this kernel and its creator. This is just my way of giving back. I am aware of some of the issues that may occur on specific kernel builds for some users as well as the difficulties faced when fine tuning the kernel and this is my response to that:
This is by no means intended to replace any of the original KT-SGS6E kernel threads. The purpose of this thread is simply to work in conjunction with them by providing a variety of builds for which users can experiment with and find which versions perform as intended on each of their respective device models. As on previous Samsung devices I am also bringing back the Ktweaker Shop filled with tons of pre-configured settings compiled by myself and others in attempt to further assist S6 & S6 EDGE users with improving their overall experiences on this device or to simply use as a baseline to work upon tweaking further. So I’ve gathered just about all of the current and previous kernel builds I had hidden within my pc as well as all the various Ktweaker settings and am sharing them with the public. I hope this makes a difference for all you guys. ENJOY!! :good:
POST #2: Reserved for UNIFIED {G92X} users
POST #3: Reserved for the KTWEAKER SHOP
POST #4: Reserved for TEST PROFILES
If at any given time you aren't already on the kernel and Ktoonsez hasn't updated his links, there'll be no need to flash previous builds when you want to receive OTA's as ALL posts will be updated regularly upon future releases. So please be sure to refer back here for all builds from this point moving forward!
I will NOT be held liable for anything that may occur to your device nor will Ktoonsez. So please...
***FLASH AT YOUR OWN RISK***
If you encounter any suspicious issues when updating the kernel, follow my recommended procedure for the best possible results:
1) Backup current Ktweaker settings
2) Open any root browser (make sure it's mounted as r/w) then navigate to /system/app/ and delete the Ktweaker and KTmoniter apk's
3) Navigate to your sdcard and delete the Ktweaker folder OR rename it by adding a ".bak" extension without the quotes.
4) {Optional} Clear all Superuser logs
5) Reboot Recovery
6) Flash kernel
7) Reboot
8) Copy any saved profiles back into /sdcard/Ktweaker/Profiles/
9) Restore Ktweaker settings
10) Profit?
NOTE: If at any point Ktoonsez no longer wants this thread open it will be closed without question.
Please visit original kernel thread for change logs, extras, etc...

Welcome to the Ktweaker Shop!
Here you will find all of the pre-configured settings provided by myself and Ktoonsez. As a proud member of Team Kernelizers, I am offering a variety of profiles specifically for S6 and S6 EDGE users with their personal needs in mind as it's pretty clear not everyone favors the same governor, scheduler, etc.. Any suggestions are always welcome. All future profiles will be added here for sharing and discussion. Keep in mind that results will always vary per device regardless on the settings being used.
All profiles have been grouped into 3 sub-categories; "Conservative", "Balanced", and "Performance", which are used to classify each profile based on their role and what they are expected to deliver to your device. The 4th sub-group is where you can find some of our best "Projects" in which offers 2 or more profiles per project. Make your selections based on your usage needs and apply what works best for you and your phone. We're here to help eachother out and with more options comes better experiences for everyone running this kernel.
So shop around.. pick and choose.. load and go!!
Installation
Download links will include the specified profile(s) as well as an "Adjustments" and "About" file. The "Adjustments" file is just a simplified view of all the changes made to a profile compared to stock settings.
1. Download the file(s) to your phone.
2. Copy ONLY the XML(s) (DO NOT copy the "Adjustments" or "About" file) to "/sdcard/KTweaker/Profiles" using a file Manager of your choice.
3. Open the Ktweaker app and click on the "Profiles" setting at the top of the slider drawer OR scroll to the bottom and select "Profiles & Scripts" then click "Restore Profile from sdcard".
4. The file you just copied should be listed there. Select the one you want to apply and confirm.
5. Make sure the "Set options on boot" setting at the top of the slider drawer shows a little green boot icon below it, indicating the settings will be applied upon reboot.
6. Profit!
IMPORTANT: Be sure to ALWAYS load your stock voltage table on BOTH CPU clusters IMMEDIATELY after applying a profile as most of these are based on an ASV10 CPU and may result in reboots!!!
1) Apply the profile
2) Quickly go to the CPU voltage for cluster 0 and click "more" and load default voltages, then click apply.
3) NOW go to the CPU voltage for cluster 1 and click "more" and load default voltages, then click apply.
4) Done!
Conservative
Asking Alexandria
This is a battery driven profile in which focuses on saving as much juice as possible while also maintaining stability and providing an extremely snappy feel to your phone. It is quite possibly one of the smoothest and snappiest battery saving profiles available.
Why Asking Alexandria?
It's named after yet another one of my top favorite metalcore bands and I chose this because Alexander The Great basically ruled the world at one point and "Alexandria" is the female equivalent to that name, which has become known to mean the "one who comes to save warriors".
"Asking" was an addition to the title name as an indication in the sense that we are all asking Alexandria what she can really do to our phone.
Coming soon....
Bless The Child
Based on Ktoonservateq and aimed towards battery. This is specifically for all the battery hungry users out there wanting to conserve as much power as possible. So don't expect the BEST but rather decent performance out of this one.
coming soon...
Dead By April
This profile attempts to bring some of the best battery life possible to your device. It is similar to Bless The Child but takes things a step further with it's heavy underclocking as well as it's higher thresholds and online blocks to prevent other cores from coming online too soon. Although It focuses very little on performance it manages to maintain a fairly smooth interface for your average daily use.
https://copy.com/oFLHg4ZG2MyvRzrq
Balanced
Balanced Bull v1
These settings are very special to me as they were my very first, dating back to the Galaxy S3, and is a profile designed for my own personal usage pattern. It has become notable for it's fairly smooth interface and amazing battery life. If this stacks up to your standards then I encourage you to use it!
https://copy.com/SKdHYHskn1NgLitp
ECLIPSE
This is a performance oriented option where great battery life is also expected to intervene. This not only will bring an incredibly stable, smooth, and snappy feel to your device but will also benefit towards longer lasting battery so you can love and enjoy your phone the way you were meant to.
coming soon
Ktoonsified v1
These settings are my settings, This is a performance oriented option in which also offers a great deal of battery life. YOU WILL NEED TO LOAD YOUR STOCK VOLTAGE TABLE THOUGH since there are 16 different bins of CPUs!!!

Ktoonsified {MOD}
This mod is intended to work as an alternative to the original Ktoonsified profile. It's specifically for the users experiencing issues such as screen wake and incoming call delays and media stutters on Ktoonsified v1 . Use this profile to repair most if not all of these issues.
NOTE: The adjustments text file will show you the few changes I've made from the original Ktoonsified profile.

SmoothManic v1
This profile was put together by none other than the BOSS himself, @ktoonsez!
The idea with this is to get the CPU really high on 2 cores when screen is touched and then bring them both back down really quick so UI is super smooth but don't kill the battery by hanging out at that high Mhz step.

Undisputed
This is a universal performance setup in which combines the essential elements of other profiles by providing equal battery life, speed, performance, and stability to bring the ultimate experience to your device.
coming soon
Performance
Feed The Machine
The exact opposite of Bless the Child. This is a performance oriented option for all hardcore users. If battery isn't a priority for you then this is a great option.
coming soon
From Ashes To New
This is a straight performance profile. It's similar to Feed The Machine and Rebirthing in the sense that it syncs the cores to the boosted frequency on touch and almost instantaneously jumps right back down to 300MHz. The difference between the profiles is that this one makes better use of all the cores. However, due to the rapid scale down I think most people will find battery life to be surprisingly good for this type of profile
coming soon
KTGaming v1
This profile was put together by none other than the BOSS himself, @ktoonsez! This is a super performance oriented option which allows me to play any game with ZERO LAG!!!!!!!

SmoothGaming v1
This profile is based on SmoothManiac v1 but with performance enhancenents to provide a much smoother gaming experience while hotplugging is active. Some of these enhancements include a much higher sampling interval as well as offline blocks to allow frequencies to scale and hotplug at a more reasonable pace.
NOTE: The adjustments file will show you the changes I've made to SmoothManiac v1.

Projects
Comatose
This project was inspired by the album of the same name by my #1 favorite rock band of all time, Skillet. It consists of 3 profiles of which are also named after 3 of my favorite tracks from this album (included in the "Extras" folder) and all focus on one key element; VARIETY.
As the name suggests, "Comatose" is geared towards battery conservation. It focuses on keeping CPU low for a prolonged period but utilizes 3 of the 4 cores on touch and the 4th on demand for fluidity. Sample rates have been decreased heavily as to increase polling and allow the other cores to quickly spike towards higher frequencies for a given task then immediately drop back down as if the component had been knocked unconscious.
The second profile is "Rebirthing". This profile will counteract the affects of Comatose by heavily boosting performance as a means to bring life and energy back into this profile that remains unconscious. Rebirthing is intended for those seeking a performance-based version of Comatose but who knows... For such a power hungry profile you may just be surprised by the great battery life it also delivers.
Some of you may not favor the heavy battery conservation that "Comatose" offers or the overall power consumption of "Rebirthing" and much prefer a mashup of elements delivered between the 2 and that is the purpose of "Whispers In the Dark". This profile is directed towards finding the right balance between these 2 profiles while still acting as a it's own profile. It utilizes most of the performance aspects from "Rebirthing" Like "Comatose" it uses a fairly high up_threshold for that extra boost in battery performance. The profile also idles at the same minimum cpu as "Comatose" but ALL profiles run at stock 2457Mhz.
All profiles maintain the same concept of rapid cpu polling. So yes, cpu will be working consistently but my theory here is that more polling will allow the kernel to rapidly check CPU usage, thus allowing CPU to change more frequently according to the load, which in turn will prevent persistent pegging of even higher frequencies and instead consume various amounts of power in various scenarios depending on your usage, consuming even less when a specific task has completed and immediately dropping the load.
This also applies to screen off states but that goes back to what was explained in this post regarding high vs low sampling rates and how they can greatly increase idle times depending on your screen off max.
coming soon
If you'd like to contribute to the Ktweaker Shop all you need to do is post the profile you'd like to share and include a brief description of it's purpose. It will then be tested thoroughly by the community and based on feedback will be submitted here in the Shop for approval and sent out to the dev so he can add the profile to the Shop in Ktweaker!

Yes they are the same, therefore use the same kernel. Not sure about the firmware but you're willing to try. However, as I'm sure you know I take no responsibility of the end result.

The worst I'd say is probably a soft brick since the devices are nearly identical but I still can't guarantee a positive result for you. It's a decision you're gonna have to make among yourself.
