[MOD] Fully Editable Headset EQ by Meltus!!

[DO NOT, UNDER ANY CIRCUMSTANCES, ATTEMPT THIS ON AN ECLAIR ROM. IT WILL BOOTLOOP. THIS ONLY WORKS ON DONUT ROMS]
Ok, first of all this is VERY experimental and it is not recommended that you keep this hack on your phone permanently. It is merely a Proof Of Concept at the moment.
What is it?
This is an edited file that you push to your phone and when activated, it allows the Headset to read from the AudioFilter.csv. The AudioFilter.csv contains an editable EQ and Compressor.
Why should i do this?
Why not? It can make your Headset sound better and, more importantly, louder. (Yes, it has my Headset Boost built in!)
How do i do it then?
Go to my downloads section and download my Equaliser.apk and either of the 2 EQ 'packages'. You must have a basic understanding of how to push my files manually.
Once they're on your phone, load up your music app and enjoy! The sound quality wont be amazing at the moment but if you want to see just how much it can be changed try pushing v6r2. It sounds absolutely terrible!
so...
Before we begin, things you need:
- A Rooted Phone
- A Rooted Phone running any DONUT ROM. [DO NOT, UNDER ANY CIRCUMSTANCES, ATTEMPT THIS ON AN ECLAIR ROM. IT WILL BOOTLOOP]
- My application and/or knowledge of how to push my mods manually.
- DO NOT ATTEMPT THIS IF YOU DO NOT KNOW WHAT YOU ARE DOING
TURN YOUR MEDIA VOLUME DOWN BEFORE YOU APPLY THIS HACK
INSTRUCTIONS
- Firstly, download my Equaliser.apk and install it on your phone
- Open up the application and select 'Always Allow' when it asks for SU permissions.
- Click the 'BACKUP FILES' button. THIS IS VERY IMPORTANT.
- Next turn your media volume down. seriously.
- Now the fun part, click 'HACK MY AUDIO!'
- Once that's completed, open up my Louder Volume Hack application (you can buy it from the market) and push v6r2. (or push the files manually, both work fine. don't forget to restart the mediaserver.)
- Enjoy!

...it sounds terrible doesn't it? V6r2 is a nice example of how extreme we can get the EQ (we can make it much worse than that too).
I've prepared 2 sets of files for you 'BASSY' and 'QUALITY'. I'll leave it up to you to determine what they sound like
Both are available in my Downloads section.
How to apply my files manually
If you would like to push the Heaset EQ file manually, instead of using the pre-made application, download the attached libaudio.zip, extract the libaudio.so file and push it to 'system/lib' then do 'killall mediaserver'
EDIT: Added some pre-made files for you guys to try out.
Once you have the libaudio.so in place, all you have to do is push both files in the .zip to system/etc then do a 'killall mediaserver' from the terminal!
Enjoy!

[reserved for future use]

Sounds interesting(lol). Gonna try it out later.
Appreciate your work on this!

nice!
So glad to see you moving forward with the editable EQ idea! I'm currently running openeclair so I won't be able to participate in betatesting. However, if BT remains broken for much longer I may go back to donut, If I do I'll be sure to help in whatever way I can.
Once again, great job Meltus!

Thanks! i got a fully editable graphical EQ in the works, but i may have to brush up on my java first lol ><

Hey Meltus it works on Eclair just have to push your backup before rebooting each time XD

Oh wow... I'm really excited about this. All this time I was waiting for someone to incorporate it into media player... and here comes Meltus and just builds a stand-alone app! Awesome!!!! BRB.... gotta test me some EQ files

Really? I assumed the files would be different. I'll test this out later.
Sorry the EQ app is pretty bare at the moment, i'll be adding in the EQ settings to it soon
By the way, these settings will now be system wide, so they should affect the BT headset too! (not been tested)

XD yeah seemed to work when I used it on Eclair just that it bootlooped I was using Eclair when I tested it for you XD so decided that backing up and then pushing before rebooting each time might fix it and it seemed to work

meltus, you're amazing! coming through once again. I've been following your threads ever since the first audio hack that you released. so I pushed libaudio.so and I pushed the "bass.zip" files from your androidaudiohacks.com download section. the EQ settings on this are amazing, exactly what I've been looking for! AHHH! THANK YOU!!! audio sounds so much better in my car. I can actually put my subs to use now! so much low-end, muahahahaha
has killall mediaserver always worked to reset the .csv files when you replace them? or is that the change that you made to libaudio.so? always hated having to reboot to test new audio settings.

I tried using this on CursorSense 1.2.6.1 and if i use the included audiolib file my phone does not boot. Will this hack work without it on a cupcake ROM?

It has only been tested on Donut Roms so i wouldn't be able to say.
I will be doing more tests and improving at time goes on but i'm having a little break at the moment
There should be no reason for this not to work on cupcake but like i said, it hasn't been tested.
Even if it isn't fully compatible, you should be able to push the file to phone and run the EQ hack whilst it's running and then push your backup if you want to reboot. It seems to be the same on Eclair ROMs.

I tried doing that but the minute I open any music application the phone freezes be it HTC Music or RockOn

I guess it isn't cupcake compatible.
I'll compile the cupcake source tomorrow and see if the file is different.

Thanks, hopefully you find the problem and can't wait for your graphic equalizer
edit: Couldn't wait for a cupcake compatible version so I flashed the latest Cyanogen ROM, and all I can say is great work, listening to music on my phone is no longer a nuisance. At first I tried your bass file but I found it a bit flat (basshead) so I made my own (I'll attach it for others). Also could you explain some of the compressor settings?

neat little app. now we just need a number of preset EQ profiles to apply and/or a graphic equalizer.

Thanks! I'll have a look at this. I released my own 'mega-bass' file on twitter yesterday - http://www.megaupload.com/?d=YLV7MO6D tell me what you think
Not for people who want serious audio quality lol. This is just bassy as i can get it without it distorting (too much ).

general questions from a new andriod user useing the Huawei U8651T

Hi there, I'm not sure if this is the right place to post this but I can't seem to post to the treads related to what about to ask.
I just got the t-mobile prism (aka: Huawei U8651T), Its my first android phone and a good step up from having used the nokia nuron 3250. I have to say I'm a little disappointed with the most simple things that this phone doesn't do and I'm already looking into at least rooting my phone if not installing a better rom (assuming there are better roms) and that is the purposed topic of this post.
I've read up on the "How to root Huawei U8651T http://forum.xda-developers.com/showthread.php?t=1698905 and it seems easy enough to do but I want to make sure that rooting and/or flashing to a different rom will actually fix the small disappointments I've found in my phone. Here is the list...
1, Camera options suck in just about every way. There are pathetic presets to control the white balance and other setting. I've had more options on far lesser phones. Not to mention the poor interface in general.
2. the music player has extremely simple with no built in EQ at all. This one I did find a way to overcome with a small global eq but serously the built in stuff should at least have a preset eq like jazz, rock, bass, flat etc.
3. the alarm clock and texting sounds have to be tmo's preset stuff. I can't set either to a custom ringtone or mp3. Again I found a work around for the alarm clock but not the texting and all these extra programs is steeling away the little memory space this phone has.
4. and finally I have seen programs on the apps/programs list that I can't use or find anywhere else. I'm not talking about the ones that run in the background that run say the keyboard or hardware, I'm talking programs I should be able to use.The one that pops out first is the Sound Recorder. its on there but I can't find anyway to actually use it.
So here is my questions... Will rooting my phone give me a way to change some of these issues? Will installing a different rom?
I'm also instrested in knowing what the CyanogenMod 7.2 STABLE (2.3.7) 16-06-2012 rom is really like vs the stock rom and what other roms there are out there that will work on my phone. I use would like to hear from KrisM22 if your out there but I've love anyone's knowledgeable opinion. thanks for your help.

by rooting & installing CM7 you will solve all this problems coz CM7 provides a wide variety of functionality.

3. You can set custom ringtones and notification sounds very easily. Create a folder on sd card called "media" within that folder create another folder "audio" and within that create a folder called "ringtones" for ringtones and "notifications" for notification sounds.

I tried several different camera apps and it all defaulted to the presets the original app had. so is it hard wired into the hardware or just the roms programing ?

Hi brothers,
I've just been flashed Cy 7.2 on my T-mo prism. But i forgot to back up stock roms. That so bad. Does anyone here have a backup image or stock rom of T-mobile prism ? Please help me!!!

Well once I commit to doing this I'll be backing up mine that I can send along to you. But tell me having run the other rom how does your phone like it? Does it address the issues I've posted? Give me your review please

This rom works quite well for me -> http://www.mediafire.com/?zr5x3lb9xr0kvvf

more info
Cool can tell me more about it? Do a review on it for me please

Well, I just like the way the screens look with the rom...you have to manually install a camera app, music app, and file manager, because the ZaD!!RoM didn't come with them. Also, the phone would shut down occasionally due to overclocking, so I had to adjust that too.
I guess what I'm saying is the ZaD!!RoM is good if you like to do a lot of your own customizing/tweaking. Otherwise, try the Cyanogenmod rom.
Good luck!

Thank you so much for place the link on the stock rom. I am trying to recover the phone back to factory WITHOUT CWM as the boot loader. I am trying to follow instructions of how to reflash in the XDA forums but run into a brick wall for the update.app is not in the stock rom that you provided. Is there something you can do to help on this?
Thanks
I'm trying to follow veer1238 instructions but do not have the update.app. Help please!:crying:

Uh Oh!
I have a T-Mobile Prism that I need to unroot and turn it back into factory conditions. There is a problem though, when I flash the factory rom, the custom recovery flashes it then it says installation aborted. I really need to fix this since I formatted the /system. Thank you for your response.

Device: T-Mobile Prism U8651T
Custom Recovery: CWM-based Recovery v6.0.1.0

Removing these apps(With Titanium backup) and installing play store alternatives is a good start but cm works too.
Poweramp is a good music app that lets you tune eq with the freq.
Stock roms usually suck until they are messed with.
(As you can see I like to modify stock to my whims and I dont like custom roms, only custom kernels)
You can try my tool in my signature because it has a rooting feature.
But if your running android 4.0 or above it wont root
In that case you will have to look for device specific methods.

6.0 Marshmallow: Missing EQ and sound settings are hidden in Play Music

The audio effect settings are now hidden in the Play Music app. I disable the app, since use Amazon for downloads (no device restrictions) and Poweramp for music. None the less, you can still access the audio effect settings, even if Play Music is disabled.
It is the same audio effect settings and appears to still be global. If it were linked to the Play Music app, I should not be able to mess with settings when the Play Music app is disabled, but I can. I created a shortcut to the Audio Effects with QuickShortcut (handy app!).
Audio Effects are accessible with the QuickShortcut app, so no need for the Play Music app.

That's just equalizer it was always there , on 5.0 sound effects was gone and put back. All you do is disable default EQ app.

The equalizers came back after the new play music update.

The Audio Effects were located in the sound page of settings (at the top). They are gone now, but can still be accessed as noted above and without Play Music active (I don't use it).
Testing Youtube and other apps. it sounds like the settings are global (for what I checked), as they were prior to the super great amazing fantastic MM update. All of those adjectives are sarcastic, since I see no improvements but do notice the EQ setting missing from where they were and connecting to a PC went from simple fast connection, to a sporadic pain sometimes.

No, it isn't global anymore.. please test further.
Also the left and right channel doesn't switch anymore when rotating in landscape.. check for right/left channel tests in Youtube.

Maybe if they'd done it correctly from the start -- meaning with no gap in playback, or at the very least a crossfade between channels -- no one would have complained and it could've stayed.

Marshmallow seems to have broken eq. I cannot get audio effects or market equalizer to do anything more than placebo eq. Even some apps with built-in eq have their eq break. . Bluetooth, any way. Yet, to test over eat buds.
---------- Post added at 03:01 PM ---------- Previous post was at 02:56 PM ----------
You can also see at a glance the eq of audio effects is pathetic, if it happened to work. . In real world, there is a huge need for huge adjustments in ear buds, speakers, environments. . The variation of sound setup is huge. .
Not to mention BBE or other clarification effects. Which is essential, on top of eq.

Workaround
Now that we know that this doesn't work, (and probably isn't going to be a priority to fix in the next software update, given Lenovo's haphazard nature of releasing broken patches) what's the best workaround? Can Viper4Android be used with the stock, rooted Rom? Or can this blunder only be fixed with a custom Rom?

It's interesting that you mention that because I had literally just discovered A.R.I.S.E. and installed it not even two hours before you posted . Thankfully, I can report that it does appear to be working brilliantly on the stock ROM when using the "Leviticus 1.3" version. :fingers-crossed:
I'll report back if I discover any issues, but so far, it looks good!

Cool! I've been using Arise since they started. Fantastic group of developers. Super nice and helpful. There are tons of options, but it can be simple as well. I'd recommend the newer Deuteronomy builds, but they're all really good. Any questions, just ask in the arise thread. Fyi there are a few incompatible versions. It'll show itself trying to take video and it'll stop with an error message that says that something else is using the mic.

Will do . I assume the additional processing required would be comparable to what I experience right now with the Note2 and equalizer found inside of S-Tweaks. Hopefully not when it's sleeping and not playing any sound though.

solved.
Go to apps in settings, scroll to default equalizer ( in my case sound alive). Disable that and then go to music app (eg spotify) and then go to the equalizer settings and it will come up with your own equalizer app (eg V4A)

Any app that can pre amp music on Android?

I already know about poweramp. I want to know if anything comes close to it or if there is such an app out there that you can pre amp the sound and make it louder and customize the base. Something similar to Viper4android

Thank you!!!!I confirm this; with alpha build 703 of poweramp, now the volume is high same the volume of stock player in s7( have a custom rom+mod v16 audio)!!!!http://forum.powerampapp.com/index.php?/forum/18-poweramp-v3-testing/

Would that mess with for example the license verification for the poweramp unlocker? I don't want to cause any issues if I install anything

Probably not. It'll be carried over. Well. There must be a significant difference in volume and quality though as mentioned above. How does it sound

Install viper4A on stock?

Yesterday i rooted my Erisin with kingo and then i wanted to flash Viper4Android. In the Standard Recovery i saw that there is no Option to flash a zip file... So how did you guys do it?

Why flash ot and not just install it and grant it root acces and hotboot it? When u install it you can let it boot up when device boots.

Hey. It only worked with kingo root. (not king root)
There is a viper4android app and no need to flash the mod like I was used to. But actually I don't use it anymore after installing latest custom Rom because of the pumped sound in the system. Together with v4a its too much..

When I tryed to root with Kingoroot, APK Installer finished with a message like "Application not installed", and the unit is not rooted
Did you used the stock "APK Installer" or used another one?
I've red that Viper4Android needs a rooted device to do successfully its job.
I appreciate sincerely your opinion about the sound obtained with Viper4Android, but I need to test it
Kind regards!

I used the apk found here: http://de.kingoapp.com/
And I used the stock installer. Viper needs root, yes. Maybe redownload the apk?

Thank you Mithy_X, the problem was that, when the apk installer warns you about all the risks that has installing Kingoroot, you have to unfold the warning message and click on the hyperlink at the end of the text instead of clicking on the acceptance button of the window.
By the way, I have to disagree with you about the sound quality obtained with Viper4Android. If you adjust a flat equalization on the stock equalizer, and adjust correctly the Viper4Android controls, the sound enhances greatly. Not only the bass are deeper, but the highs are more brights, vocals more clean, and in general, the sound improve. You have to check the control about forcing V4A in all applications, just because, if not, sound player does not use it.

I completely agree with you. I always use V4A...that's the main reason I bought a car android device in first place
You can also try to use the high quality IRS (Impulse Response Samples) from here: http://forum.xda-developers.com/showthread.php?t=2439254. It improves the sound quality a lot.

By the way... Any good flac player? I've tried Player Pro and it really makes difference.
Kind regards!

Devilsoft, one question... Is there something to do for the convolver function to work properly? I have installed the IRS filters, activated the function and selected different filters, but I cannot appreciate difference... the rest of functions work very fine: Equalizer, Loudness, Rever... All but Convolver, that seems to do nothing...
Regards,

Just found the problem.. It was due to I didn't put the IRS files right into kernel folder, but in a subfolder into it. What I don't understand is why they appear in the list of convolver filters although being in a subfolder, but then don't use them. Once the filters are in the kernel folder, they not only appear in the list, but they are used too.
The filters are fantastic. If you use the one you like, it is almost unnecessary to activate the equalizer, just only the rever to colourize a little the sound and perhaps the Loudness.

Sorry for not specifying that the files needs to go to that subfolder.
I also use only IRS and some clarity with XiFi setting and 3.5DB selected. The IRS, i preffer "Traks Compression 2" and "Waves Headphones".
Also, try to lock it to Bluetooth or USB DOCK and switch to Advanced on Viper4Android. Once you'll do that, you will unleash the true power of Viper4Android. You will not be dissapointed
About FLAC playback, I only use PowerAmp, with all Equalizers disabled (EQ and Tone) and Settings -> Audio -> Advanced Tweaks -> Direct Volume Control (to be unchecked).
