[Q] Best audio mods for Note 2?

Me myself and I are running Android Revolution HD 6.0 with Perseus 29 kernel on my grey Note 2. With this perseus kernel you have a few audio options through sTweaks but I can't get my 24bit 96Khz FLACS sound like I would like to.. The bass keeps sounding a little woozy.. I would like to have cleaner bass and a little more detailed mids.
I am doing my listening test with 3 pairs of headphones (Stock Samsung earphones, B&W C5 in-earphones and cheapass Sehnheiser HD201 headphones)
I am using different albums for my test containing: Pink Floyd - Dark Side of the Moon, Michael Jackson - Thriller, Kendrick Lamar - Good Kid, Beatles - Love. These albums are all 24 bits and 88.2Khz or 96khz and played with Neutron Music Player.
Mods and apps I tried:
AC!D (works but better without stweaks.. stweaks seems to overrule some stuff wich results in distortion)
Awesome Beats (doesn't seem to work on my rom and kernel)
Neutron Music Player (Fine player with some nice audiophile options but poor interface)
Sony Walkman Player (Doesn't want to install)
sTweaks (Haven't found right settings for it yet and I don't want it to interfere with AC!D)
The problem is them interfering with each other.. I think AC!D does a fine job but its interfering witch sTweaks I guess.. Still some sort of distortion.
What do you run on your Note 2 to get the purest audiophile possible sound out of it? Please also note what rom and kernel you are running not every mod is compatible with every rom or kernel.

Have you tried installing Beats audio Installer [ROOT] from the Play store it helped my sound alot make sure you make a nand backup though you cant un install it.

What rom and kernel are you running this Beats installer on?

Im using omega 8.0 rom with the acid mod installed and sony walkmann player. im only using stock headphone atm but the sound is great on them.
Ive included in the post the sony walkman app that works with my note 2 and the acid mod which needs to be flashed via cwm. If this helps please hit the thanks button.

I don;t know how you find it, but I used this for a while then uninstalled as was draining my battery too quickly. Walkman standalone fine, but not with the mod. However Beats worked well with Walkman.

In my mind there is currently no doubt which kernel has the best wolfson mod: neak. It's a combination of scoobydoo and another mod whose name escapes me.
Perhaps its bass frequency tuning will remedy some of your issues. The mids are also more pronounced when using dac direct in my opinion.
All these software mods never impressed me, no offense to anyone.

Would you please comment on the ability to control the headphone amplifier and the Media Volume independently like could be performed on the SGS with Voodoo Sound? I don't have a Note 2 yet--- one of my main purchasing decisions is based on the ability to use Scoobydoo/STweaks to control the headphone amplifier volume independently. Thanks in advance.

Yes, sort of, in neak there is a volume hack similar to the one in voodoo, which makes you able to override the channel volume, so that the end result is about the same as with voodoo.
Your situation sounds very much like mine, I came from the sgs and took a leap of faith hoping that some voodoo mod would arise at some point, and it did! :thumbup:

Interesting, I suppose I will have to see how development for the Verizon variant goes. Hopefully, I will be able to find a way to get Scooby/STweaks working like Voodoo. It is hard to try until I get the device, but my upgrade is at the end of the week!
Sent from my ADR6425LVW using Tapatalk 2

In case anybody cares, Perseus kernel with Stweaks allows to independently control headphone amplifier volume and media volume. It is essentially the same features as Voodoo, but without the Voodoo app. It is under the Audio section of Stweaks.
Awesome!

ok i got a pair f beats solo and they are overwellmed if i turn up the volume all the way up ... and i was able to do that by frst rooting my device and flashing UNEAK kernel it comes with wolfson audio and just go to play store and download uNEAK engine app and you will have close to pc sound out of your note 2 just make sure your headphones can handle the power your phone will put out .. like i said i got a pair of solos that cant keep up .. its time to upgrade my headphones ... power amp player is a good player too alot of otions but love the MUSIC SQUARE FEATURE ON STOCK PLAYER

[Guide] Optimal Galaxy Nexus Audio Setup

Disclaimer: I am not a developer and have no rights or claim to any of the files listed below. I only use them to "Rock Out"
Like many of you I have struggled with the lack luster audio output of the Galaxy Nexus. Nearly a year later and much has been done to correct this. I was using Volume + for a while before upgrading to 4.2.1 which broke its functionality and limited the effect it had on my audio output. There are two formidable modifications out right now that will take your GNex to the next level but because they are similar in functionality I will discuss the one that provides the most merged features.
Before you get started please ensure that you have rooted your phone, have an updated custom recovery such as TWRP or CWM. I will not tell you which Kernel to use, however I will tell you that I have this 100% working on my Verizon Galaxy Nexus using AOKP 4.2.1 or AOKP MR1 BuildX. The MOD developers also state that it is confirmed working for the Galaxy Nexus 4.2.1 (AOKP) I do not know if any other ROM will work with this phone.
The MOD is called Ac!d Audio Engine which combines Beats Drivers found in some HTC phones with other sound engines such as Sony's Xlouder, Dolby, etc... There is another thread for the mod that I will link below. You can go there and read/download the MOD and I will give you a brief description below on initial setup.
Before installing this please make a full backup of you Galaxy Nexus. Even though this works for most phones it is also ROM dependent. With that in mind make a backup please. Coming from any other ROM or Version of AOKP you must do a FULL WIPE!!!! I would also download each component and upload to your phones internal SD before you run through the steps. This way you can install them all one after another and not have to wait for your phone to optimize applications multiple times.
Step 1 - Please visit http://aokp.co/release-jb-mr1-build-2/
Download the version or this for your phone. Like many developers they list the phones as the code name for instance VZN is Toro.
Install this using the latest version of CWM or TWRP. I realize most people get really attached to ROM developers and stick with them. I will promise you that this is totally worth trying for the sound improvement not only in quality but shear DB gain.
Wipe Dalvik
Step 2 - Install the version of GAPPS listed on the AOKP website. Remember that as this thread ages the ROM could change as well as GAPPS.
Wipe Dalvik
Step 3 (Optional) - Install your favorite Kernel. As long as it is verified for JB 4.2.1 it should work. I use LeanKernel (not tested on GSM) you can get that form here: http://rootzwiki.com/topic/13092-kernel-leankernel-minimalistic-kernel-48-58-12313/
Wipe Dalvik
Step 4: Install the Ac!d Audio Engine found here: http://forum.xda-developers.com/showthread.php?t=1923630
Wipe Dalvik
Also Important download the Ac!d Noozoxide or Ac!d Awesome Beats appllication and flash as well. It is possible against the Dev's advice to install both of them. As long as you remember not to configure them both you should not get any audio issues. I tend to uninstall them via the standard app drawer if I want to switch and reinstall them later should I want to switch back.
Once installed bootup, go to settings, sound, music effects and choose the DSP you want to use either Awesome Beats or Noozoxide. Next open up a music player such as Google Music and start your favorite tune. Next open the application drawer and choose the DSP you installed to open. Tweak headphones first. Inside the application you will notice immediate change by enabling the equalizer and editing the sliders. Please note that depending on the quality of your headphones these values may need to be lower than expected to get rid of rattling or audio anomalies. The other two tweakable settings are for build in speaker and bluetooth audio output.
From my experience Awesome Beats is configurable louder however that introduces artifacts into your music if it crosses the thresh hold that your headphones can handle. Noozoxide has a few different filters and is easier to tweak. The reason I say to use either one of these is because sounds across you the entire phone are improved and louder; Calls, notifications, other player apps like Pandora etc.
I hope anyone who views this gives it a try. I wanted to wait until AOKP 4.2.1 had matured past build one to give everyone a smoother experience. Also this will push your phones DAC much harder. Certain kinds of headphones such as over ear (50mm +) couldn't really be driven hard prior to this MOD but now they can so you may experience additional battery drain if not using smaller ear buds. If you love music like I do most people will make this sacrifice.
Here is a video of an installation and tweaking of a Galaxy S3. The Galaxy Nexus will be similar once the files have been flashed and you can tweak your audio settings: http://www.youtube.com/watch?v=8pkmnKN-r9Y
Please let me know if you find this useful and hopefully you fall back in love with your phone all over again. :highfive::victory:
P.S. I really love wiping my Dalvik
Thanks, Joe.

Hey that's great news which ROM/ Kernel combination are you using with Ac!d Audio?

I'm running CM 10.1 M1. I'll try this out later tonight when I get the chance and let you know if it works. Thanks for doing the work!

I installed this after I updated my tenderloin to the latest CM 9 to the latest nighty. The first couple of flashes played the initial sounds but as soon as I plugged in headphones all sounds we failed to play. I simply dirty flashed the ROM a few times including the MOD until I turned off the ac!d audio notifications. Afterward I changed my dsp to Noozoxide and it worked perfectly. Strangely though the audio filters work and sound great but it still cannot compare to WebOS volume wise. This to me is proof that the driver choice is everything because the Touchpad has the better audio hardware than most mobile/tablet. Didn't want to stray from the Galaxy Nexus discussion but this could be viable for the GNex on CM 9+ or ICS in general.

No I flashed the ROM with the ac!d audio mod. I also chose noozoxide as the DSP but with CM you could try the included DSP it is identical to the awesome beats DSP. With ac!d audio you really need an equalizer to utilize the drivers. Even if you leave it flat you can at least get a dB gain.

I recall supercurio saying something along the lines of these not actually improving audio performance in measurements and such. I've looked at these before but I sceptical.... anyone have actual measure of improved performance and not just placebo?
Sent from my Galaxy Nexus using Tapatalk 2

I do not know if the audio drivers/ engine components are Placebo or not. What I do know is that my phone plays very deep bass and sounds great afterward. This might only be attributed to the DSP but I can tell you that Music FX is a terrible DSP and Volume+ stopped working with 4.2.1. So anything I can do to be satisfied with sounds is better than listening to SuperCurio debunk things with no proof. Is it better than DSP manager that comes with CM? I do not know.But if you can make a backup and it doesn't break your phone I also cant say there's any reason for skepticism.

acid works great with pa so far. flashed yesterday and havent had any issues when i've played over speaker or headphone port. Better then DSP manger... meh i can still crank up the bass when i am feelin in the mood and sounds great.

Yeah, on 10.1 I couldn't get either Noozoxide or AC!D Awesome Beats to kick in. Only the default DSP packed with CM worked. I tried it through my IEMs and my car. Though, yeah, even that was noticeably better.

Why dont you post some of this science? Every idiot knows that a DSP is a valuable tool... Which is what I said. Why are you proverbially blowing supercurio? I understand if he's butthurt cause not every Hw manufacturer uses wolfsen as the DAC hense voodoo audio doesn't work. Cause here you come to defend his honor in a thread that you don't belong in... Sorry truth sucks. Now stop being a flaming troll. You will be slapped down every time in my thread...

I'm sorry that it doesn't work. It could be possible that cm 10.1 only works with built in DSP. It does work with aokp and paranoid android though which are both 4.2.1. So much for placebo though if even the packaged DSP manager was better... Granted. I suppose drivers actually make a difference despite what people who havn't tried it believe. Because the DSP is just an equalizer. The drivers are what improve the DAC performance.
P.S. I trust a curio to hold my TV in my bedroom not to tell me about what works on my phone.

[Mod] [Theme] [LS8, LSD, LSE, MS1] Inverted HW Equalizer FX (MusicFX based)

Hi
Samsung roms comes with a system app named MusicFX. This app is the core app for the built in 5 band equalizer and effects. The only problem is that the app does not have a user interface, so without a music player that can make use of MusicFX, it is pretty much useless.. There are many equalizer apps on google play, but non of them works on Sammy JB. I've tested many of them, until I came across a free app called Equalizer FX:
https://play.google.com/store/apps/details?id=com.devdnua.equalizer.free&feature=search_result
Of course this app did not work on Sammy JB either (and did not work well on ICS because many music players did not support it, so it only worked if you use it to play single file at a time). However, after de-compiling thus app, I noticed that it has very similar code to the MusicFX system app from Sammy JB (XWLSD build). So I decided to make an experiment and replaced the similar smali files of Eq FX by the ones from Our MusicFX (LSD). After trial and error and some label renaming and modifications, I got it to work on our JB.
Moreover, I also inverted the app with cool JB reloaded blue theme and I disabled the built in ad banner (Since this app is now only compatible with Sammy JB roms, I'm guessing this ad blocking does not violates forum rules.. If Mods think otherwise, just let me know and I will replace it with a version that includes ads just like the Google play free versions. Note that this modded app uses the free version package).
The app is signed so you may install it as any other app.
I tested it with many music players including default and poweramp and it works. I also tested it with voice call from speaker and it is working.
Here is the link to download:
https://dl.dropbox.com/u/58987384/EqualizerFX_Mod.apk
Install then go to settings - music effects and select Equalizer FX.
Next I will try to mod it further so it will have separate profiles for headphones, speaker and Bluetooth (currently I'm trying to figure how to do it by looking at the code of AwesomeBeats that has this functionality)
Enjoy and let me know if it works (state the version of your rom. Guaranteed to work on XWLSD).
Credits:
devdnua for original Equalizer FX app (v1.3.1 free)
Features:
* Works independently (regardless of the player used. for Poweramp you'll need to disable audio direct access)
* 5 band equalizer (using build in HW eq of onboard Soundchip)
* Bass boost
* All available MusicFX profiles
* Can add new user profiles
* Virtualization
* Black Blue JB theme
* Ad free

Nice work bro!

Working grate! Good job

Chameleon Rom(LS8) and Latest Poweramp(feature using MusicFX directly added)
Works fine.
The range of frequency in hearing is little bit different from other apps like this(Equalizer via Smart Android Apps, etc...) but it is just my noobynish about the difference.
Thanx a lot mate
I'll use this few days more to test about the bug others have(going back all EQ band into 0 for few seconds).
Can you adopt the opinion or idea? I have some and these maybe cool...
1. Backing up my EQ value which I set through syncing my google account(to backup my settings much safe and apply any devices I use)
2. Add methods for adjusting EQ with type numbers with keyboard apps or toggle + and - ( too hard to set the values through dragging on touch )

As for the range, this eq make use of the internal hardware DSP controlled by the MusicFX engine. It turns out that the equalizer built in is not a graphic eq, but rather a parametric eq. This means when you boost one slide, you are actually boosting or attenuating entire frequency band, who's center frequency is the freq of the slide being boosted. i.e the 14kHz slide will affect an entire band ranging from ~8khz up to 18khz..
As for the slide adjust sensitivity, I agree, it is a little jumpy.. But this is how the original app dev made the UI. Its gonna take me some time to develop my dev skills to be able to do some advance modding. i was only lucky to notice that the original app is nothing but a UI made for MusicFX.apk, that includes it's own MusicFX taken from AOSP rom (this is why the original app did not work for Sammy JB). I only replaced the lines of code for the old musicFX with ones taked from new Sammy JB rom and of course I also changed the app theme.
I'm currently working on an AIO audio mod for JB that will combine AC!D audio + Beats + Xloud + Alsa + ClearAudio in one working CWM mod.

M8, that sounds really awesome as the original AC!D 7.0 is a bit buggy on SGS2 based on Sammy JB.
I would defenitely try it when you release the pack

So amazing! Others have a specified same bug(EQs turn off about a couple of seconds) but this is not.
I think this app is the only flawless and the best EQ app

I'll definitely give this a try, I've always like noozyoxide rewire but for some reason I can download it on my s2.
This one seems promising considering it works with the hw.

I can remove it permanently by a mod, but I don't think most people will like it this way.. You can easily access the eq this way. However, if you're on new JB rom, you can turn off notifications from settings - applications for this app

works fine on Captivate I897 with Xylon JB rom
any possibility to incorporate SRS mod(i-wow)?
thanks for the app.

I'll give this a try. Looking forward for your next project!

Hi guys! My name Dmitry. I am CEO of devdnua and developer of Equalizer FX

I will be grateful if you tell me what you have fixed.

[Q] NovaThor settings app for s4 mini?

Is there an app such as NovaThorSettings.apk mediafire.com/download/knos4r89pskmpgq/NovaThorSettings.apk for our device in which we can overclock sound gain, etc. Mainly need it to improve sound gain for headset. Currently on cm11 M11 (l9195).

NovaThor settings app is meant for devices with st-ericsson novathor chipset. S3 Mini, Ace 2 , S Advance, Xperia U,P,Go.Sola etc.
That app works with kernels that are built on common source code. So it will not work on any other device. Not s4 mini for sure.
You can use any kernel tweaking app on playstore. For overclocking i use no-frills app. It is easy and settings are retained over reboots.
Not sure about sound gain tweaks though.

[Discussion/DEV/ROM|Kernel] quad dac/es9218p on non-stock ROMs (lineageOS,etc.)

I've researched on the web for quite some time on this topic but didn't find anything definitive yet (a clear answer if it works - how to set up, etc.):
some are mentioning that only the right app would be needed to be used (well, no)
a few are mentioning that there is supposed to be an app that toggles between default dac (wcd934x) and quad dac (es9218p)
others are referring to a setting in build.prop (nope, the ROM doesn't have the mechanisms to react to that - and neither do the drivers most likely - or at least we need to make sure that this stuff is included for us)
then there are a few mentioned cases that there's support on lineageOS on board to utilize the es9218*
there's also occurences where it's mentioned that the sound stops working entirely when switching tracks (?!) - so it's still WIP
so at least the kernel needs to be set up that way - but there's probably more to it

edit:
For those who only use the quad dac for local playback (music stored on their device; NO Youtube, Streaming, etc. with Quad DAC on LineageOS/AEX/RR for now) - there is an app (for purchase) that activates & uses the quad dac (es9218p)
I've tested it and got the same specific quirk / behavior I got on LG Stock ROM with activated quad dac option.
The app is not cheap (6.99 EUR, >8 USD) - but it's totally worth it, the UI is great, the sound output is awesome (finally quad dac on non-stock !) and it uses a "custom developed USB audio driver"
extreamsd said:
This bypasses the Android audio system completely, meaning that Android's limitations regarding bit resolution and sample rate (16-bit/48kHz) are made irrelevant and high quality audio streams are fed directly to the DAC, making playback up to 32-bit at 384kHz possible (depending on the DAC capabilities) or even DSD.

Well, it's not fully "solved" - since only locally played content (no videos ! no streaming !),
but at least local content is played through the quad dac (es9218p).
So thank you very much for that hint (and everyone else who kept on mentioning it)
And: YES, the quad dac definitely is being used with USB Audio Player PRO
First I thought that the more punchy sound output could be placebo/imagination (with Xiaomi Piston V2 & the B & O Play Headphones),
but then I plugged in the Xiami Hybrid Pro (these are the only headphones that don't work with the quad dac for me - since they cause a extreme loud hissing/static on the left channel),
and after a few seconds I got the characteristic hissing on the left channel - that means that the es9218p DAC/sound card/AMP is definitely being used
That's the same behavior I got on LG Stock ROM after enabling the quad dac

In theory we would just need to write a HAL or something like that, which interacts with the kernel driver, its already there, just something needs to talk to it.
And some Overlay in the Settings to enable/disable the HAL.
The HAL would be C/++ while the Settings overlay would then be Java .... I could do the later.

I don't really have the programming skills to do either, but I'll buy you guys a beer if you figure it out. That and the vibration motor issues are the only reason I'm still on a stock ROM.

Vibration motor issues may be solved. Dev is currently trying user @Krakophyst suggestion to replace vibration motor files with those from V35. Now why that would work better than actual V30 files, don't know. But it worked for the user.

The vibration problem came up, but I think I fixed it by replacing vibration related files in /vendor and its subfolders with LG V35's files and it has been working fine for about three days now.

It works, because the V35 files have to work on AOSP (because of treble implementation on the V35), while ours depend heavily on the LG framework (which probably does its own stuff to the vibration services), and arent supposed to ever run on AOSP.

Aha. Then score one for Treble on an LG phone that has some similar features to ours. V35 may never get bootloader unlock and root, but we can cannibalize it for the V30.

Wait!?!? So could volte possibly work with the v35 files???

IF (a big if) volte works on GSIs (which nobody tried so far from what i know, i only know 1 person with a G7, and he cant use VoLTE, thanks to the carrier), those files are highly device specific (or atleast SoC specific), its very unlikely that those would work for us.
I could try, but dont get your hopes up on that.

One can dream though! Lol. Of you need me to test, let me know. Thanks!

I grabbed the app, it had some Network options (notably for Tidal and Google Play Music) I would assume using those options from within the app would use the DAC? Can't test personally as I'm currently using Spotify but would happily switch if I could use the DAC on a streaming service, assuming at least ~80% songs I have on Spotify are available there.

Could very well be that it provides or uses hooks to interact with those and I guess it should work (if it works, if it doesn't you can nag the devs to fix it - it's a somewhat "premium" priced app after all, and support is to be expected )
I'm not using any streaming services, sorry - so can't test.
Pretty sure there must be users of Spotify here around so maybe those can give some feedback

Edit: mistyped
Anyways I started a Tidal subscription (hifi student plan). From listening to a couple songs things definitely seem clearer but can't say for sure if it's using the DAC or placebo/better quality audio is the cause.

I probably will be switching off Spotify in favor of this; only because the student plan for it exists and I do hear an audible difference with their hifi settings ($19.99/month for hifi plan without a student discount yeeesh).

even using this app on non stock rom can we still get the same high volume output from the stock rom with HIM sound mod?

Anyone tried the Onkyo HF Player app?

just tried it with the Xiaomi Pro HD Hybrid and I get the characteristic strong hissing noise in one of the channels (left channel) - that's the only headphones I get that weird thing with when the quad dac is activated (on stock ROM).
This confirms that the es9218p ("quad dac") also works with Onkyo HF Player on non-Stock :good:

So obviously these applications HF player and USB audio pro player have some line of code that is triggering the quad DAC to be utilized. Correct?

And one also works with streaming media.

Would you still need to use higher ohm headphones to enable the quad DAC , or will this (USB Player Pro) allow any headphones to work with it?
I've got 4 sets of IEMs that I love, and would hate to have to start all over again buying new ones.

Nope, I'm using the quad/dedicated DAC with "normal", low ohm/impedance headphones myself,
the only "difference" is that there isn't much noticeable difference compared to the default (qualcomm) audio DAC
So you'll be fine,
you can choose to get yourself higher ohm headphones in the future (after careful evaluation, of course) take your time to choose the ones that best fit your hearing preferences (sound response, etc.)

Any updates on getting the dac to work with non stock roms?
