Voodoo mods for Galaxy Nexus

Hi everyone!

I feel the need to create a post here as my mail & twitter accounts are filled with "Please support Galaxy Nexus" requests, pressuring me everyday.
My goal here is not to generate expectations or start teasing but to give answers I can give.

So!
What I'll do and what I'll not do on Galaxy Nexus:

Won't do:

Voodoo Sound:

Yea, I know, I said a few weeks ago I might add Galaxy Nexus in Voodoo sound but eventually that won't be the case for several reasons.

- Galaxy Nexus audio quality potential is good but not quite as good as what I target.

- Galaxy Nexus audio codec, TI TWL6040 has no DSP, which means:
Parametric EQ
Stereo enhancements
Advanced recording presets using Dynamic Range Compression
Using hardware: those cannot be done.
Its the signature and exclusive features of Voodoo Sound and what matters to me.
I know devices with WM8994 tend to become old compared to the latest generation but I don't care.
Sound quality stay just as excellent and class-leading, that's what's important no matter how many new devices are released each week.

Will do:

Voodoo LOUDER:

That's why I created this different app, in order to host useful audio mods/hacks even if they don't reach the quality and features I require for Voodoo Sound.

Things I'll implement here:

- Analog headphone amplifier control, with perfect OS integration and automatic optimal setup for the best audio quality results.
If there are a few dB left to squeeze at maximum output level, the biggest interest here is the opposite: with optimizations for sensitive headphones & in-ear.

I'll implement a few more things but you'll see it by yourself.
Where there will be no compromise, its about usability, seamless experience, automatic optimal settings and most importantly no custom kernel requirements (only root)

This is why it require more work (and more time) than random hacks but eventually its of course worth it as I'm sure it will become one of the app you'll use daily.


Wi-fi screen-off fix:

Wi-fi is terrible with several routers (loosing every packet as soon as the screen turns off) and that has to be fixed.
I started working on it as well but as usual, I target a patching & flashing free solution.


Too soon to comment:

Screen color rendering customization and calibration − long term project unifying most Super AMOLED and LCD Samsung flagships.

General

- no ETA. It's done when it's done.
- Don't count on anything before it's actually released. Some part can be very challenging due to constrains (compatibility, no flashing) and might be impossible, or possible, or take months.. I'm sure you see what I mean

I say that because if the devs I try to publish look like simple apps, they depend on crazy hacks, doing things not how it was supposed to. So there's always research and challenges behind and it the outcome can be better but also worse than expected.

Surprise

A little app for you, sort of tech demo of future Display Expert features.

Download Voodoo Galaxy Nexus Display Experiment 0.2

Requirements:
- root
- standard/official kernel, or any custom one without randomly unchecked build options.

All settings are based on hardware reconfiguration of the Super AMOLED HD panel driver and controller.

ATM I'm working on new driver model and tools that are extremely powerful and allow to do a lot more than before without custom kernel or even kernel driver.

Its common to all my mods

Just to tell I make good progress in the new driver (yet another) model I name Voodoo Kaudio and that will be powering Future LOUDER and Voodoo sound implementation.

- No-kernel userspace drive: done, I use it in Display Expert already (first beta, Galaxy S II only soon to be released)
- Kaudio: generic driver for my audio mods when userspace driver is not enough: something like 45%.

Currently I'm working on Kaudio in a big rush to complete it in order to port Voodoo Sound to Transformer ICS.

The Gingerbread Man said:

Yes I suppose it is after re reading it. I was just a little unsure as in your OP you say voodoo sound won't be possible due to hardware and a few days ago this new kaudio app will feature voodoo sound and louder feature and if it is actually going to be avaible for galaxy nexus users or only the sgs2?

What I really meant though was some kind if change log as to how things are going within your OP for simple reference but that might be better suited after you actually publicly release kaudio. Anyway don't worry about it and carry on doing what you do best Super C

Yes Kaudio is a new kind of driver (Kernel-side) designed based on the experience I acquired since I started building mods.

At the opposite of old Voodoo sound kernel drivers, it's inactive and empty after being loaded: does strictly nothing.
Then its programmed by a set of various action rules from one of my apps plus some real-time actions. That makes it portable, reconfigurable and extensible to the envy.

The current methods I use for LOUDER on Samsung Exynos chipsets are not valid for Galaxy Nexus, but Kaudio will be.
Kaudio drivers family will be used internally by LOUDER and Voodoo sound even if its 2 distinct apps for different devices.
