[GUIDE][MOD] Tuned MegaBassBeats for SGY (update-3/6/2012)
D3HuM4NiZ3D has made a post about "MegaBassBeats" in dev section. I don't want to make a kind of double post. from now on I'll made this post focused to explain on how it work and how to improve it. even if the tittle said that its for SGY it will work also on other Gingerbread based ROM. it tested on SGY, SG-Fit, SG-Mini, and SG-Gio. you can get all version for all my modified MegaBassBeat here. please check changelog for further details for every version.
btw, I've found something funny. if you find any mod called ultimate_multimedia_enhancement, it is actually same with my the one in this link.
this patch will install several files including two apk, a framework file, lib files, and some additional needed files in /system/etc/. this mod also include bravia engine mod. I've added the framework, the lib, and the xml file needed for bravia engine. for an addition from v1.2 I've also added dsp manager for best result. please delete your dsp manager if you already have one.
PS:
1. do it with your own risk
2. no need to thank nor press that button for me. I'm just a noob, give that for the original dev instead.
3. special credits for D3HuM4NiZ3D who has kindly given me the permission to modify his work. you can get the original link here. http://forum.xda-developers.com/show....php?t=1642961

HOW TO UNINSTALL IT
=================
well...no one can make a single mod which suitable for all kind of music. if you don't satisfy with this work, but too lazy to modify the setting as described in 2nd post you can follow these guide to uninstall this mod. it won't be easy and only can be done in a rooted device with root explorer installed.
1. extract megabassbeat zip file.
2. make a list of all files in that zip file
3. open your root explorer and delete these file
Code:
- in /system/app delete audioeffectservice.apk
- in /system/bin delete all files listed in megabassbeat
- in /system/etc delete all files listed in megabassbeat
- in /system/framework delete all files listed in megabassbeat
- in /system/lib delete all files listed in megabassbeat except libaudioeffect_jni.so and audio.so in /system/lib/bluez-plugin
basicly this mod is kind of improvement for old beats audio. beats audio have two different version. the newer one have b1.jar inside it. it has bad issue with several music player. the older one doesn't have b1.jar. MegaBassBeat combine xLoud mod+old beats audio to get more solid bass sound.
how it works?
it will install an apk and a framework and the lib needed to our rom. both of them works as enhancement for our audio system. they're using some files in /system/etc/ as their default setting. we can modify them as we like.
how to modify it?
at this time I can only change the setting for equalizer setting. if you didn't satisfy with the sound quality, you can modify it by yourself. go to /system/etc/audio. you'll find a lot of *txt files. those files contain all the value for audio setting. in this mod, you'll need to change the setting in eqfilter.txt.
the value from A to U is the equalizer setting. you can change the value from -15000 to 15000. please be carefull since any value you set in this file can affect on your sound quality so much. after modifying this file, you have to copy eqfilter.txt to /system/etc too.
btw, further modification to all files in /system/etc/audio is possible. however, I don't know the right value for the setting. the other file contain a lot of variable, make it difficult to understand. please contact me if someone know how to modify those files. I'll include them in my latest update.
I'm planning to leave this project for a while. I'll give you all details modification I've done in the original work. beside adding more files into the original work. I've change the value in three files. if you extract my latest version, you'll see some files with *xxx1 extension. thats the original file comes from dehumanized. the one without '1' is my modified one. those three files are: eqfilter.txt, HP_audio.csv, and audio_effects.conf.
eqfilter editing is easy. you already can find the guide on 2nd post. this files comes from the xLoud mod. for the latest value you can check in my latest version.
HP_audio.csv contain the setting for beats audio. the original value is

audio_effects.conf contain the additional library setting and the setting. I'll only show you my edited part here since the file is quite long.
Code:
libraries {
bundle {
path /system/lib/soundfx/libbundlewrapper.so
}
reverb {
path /system/lib/soundfx/libreverbwrapper.so
}
visualizer {
path /system/lib/soundfx/libvisualizer.so
}
pre_processing {
path /system/lib/soundfx/libaudiopreprocessing.so
}
}
I add these lines to load the sound lib
SRS {
path /system/lib/libsrsfx.so
}
bass_enhancement {
path /system/lib/libbeatsbass.so
}
then for the effect setting, I added these lines
effects {
dynamic_bass_boost {
library SRS
uuid f7a247b0-1a7b-11e0-bb0d-2a30dfd72085
}
srsgeq5 {
library SRS
uuid f7a247c2-1a7b-11e0-bb0d-2a30dfd72085
}
wowhd {
library SRS
uuid f7a247d2-1a7b-11e0-bb0d-2a30dfd72085
I still can't understand the uuid stuffs. those lines are taken from beats audio.
all the additional files are taken from various sound tweak. there are about 5-7 sound enhancement used to improve this work. please don't ask me since I've mixed them and can't remember all of them.
I'm afraid all the tut are already included in my second post. modifying those file are not easy. I doubt if someone could find the correct variable and value for every files.
@hell_lock: just try it. it won't harm your device. this mod is work with all music player and any equalizer app. best result may come from poweramp music player + cm7 dsp manager.
