Radio sound problem
Hi Supercurio, thanks for your work for SGS sound! I've been following the development and got the donate version yesterday, looking forward to further enhancements
Music sounds really good now, also from the radio with the corrected bass setting. Before this the radio sound was so bad I didn't even care to use it. Unfortunately I noticed that my radio has a disturbing background noise, sort of like a helicopter sound in the background. It is very easy to hear when there's a silent moment, and in speech.
I wonder if this is something that could be corrected with software, or is my device faulty?

Yes, it's just better
Thanks to the anonymous engineer who found and share the trick
Wasn't me ^^
Sure, volume settings, both analog and digital (android media) are the same as in previous version.
If you use a kernel published by hardcore, maybe try to update it, he published some broken versions earlier.
Thanks
Yes oversampling improve the digital filtering quality of the signal before it's sent to the DAC, and makes the DAC runs at a higher rate.
It reduces the distortion and improve the SNR too a little bit, but mostly, it helps filter high frequencies people cannot hear but only feel and it acts on the listening fatigue.
This week I will publish measurements and analysis demonstrating the effect of those settings.
This is just a ClockWorkMod recovery thing (about apps2sd), you can safely ignore it.
Here's a suggestion.
Can you collaborate with the devs for any of the music players to integrate your volume control in their software? Reason is, some music players have re-mapped the volume buttons to skip / shuffle tracks. And it might be possible to integrate your app with their code.
If your mod requires the app to be running, then integrating with a music app will probably be the best way to go. And it makes sense since most of us need to change analog volume only when listening to music.
So, the paid version of a music player can include support for the paid version of your volume control which we can then buy from the market and install. Win - win for both devs.
Like the idea?
Yes, I could define global Intents that other apps could use to change the level.
But I will try first to do it the best way possible, meaning it won't require any change at all in any App, and will work for the whole system
I think I know how to do that now.
BTW. this is about the volume change right?
Alright, I won't forget this one
I also would be interested to have call through headphones. 15$

Hi discophil.
This kind of setting would be quite not easy at all to use I guess on the phone.
Maybe I could do that -preset without DRC- , with an input gain slider + a proper VU-Meter to help choose the most adequate gain.
But I'm not convinced yet that it would be useful in real life usage.
There is a "Headphone Amplifier" dedicated launcher icon you can use for this purpose
Hi Tube guy
Nah, this issue is the reported "crackling/pop" issue some people experience.
I have some ideas about how to fix it but didn't had the chance to test them yet.
Wow yes, easy
Will someone manage to saturate this thing − without becoming deaf −
Edit: hehe, little distortion at 4:20 ^^ (bass): congrats you did it !

Hardcore released K12Q-T7 with completely disabled logcat.
Try it. It's very smooth too and includes the latest Voodoo Sound Driver.

Hi
Didn't noticed it.
Can you describe your hardware setup ? Was the device USB plugged during your test?

That's a "dirty" way to solve it, there is a proper way....
http://developer.android.com/resour...ample/android/apis/app/LauncherShortcuts.html
Multiple app-icons is annoying.
To my knowledge the issue is created by klogd (general Linux logging system) and not logcat (android specific)
But who knows, I'm listening to reports
I think hardcore disabled klogd too! Please check with him!To my knowledge the issue is created by klogd (general Linux logging system) and not logcat (android specific)

Yes it's just temporary until it becomes a real widget too
BTW it cannot be so much dirty when it's something contained in 1-line of code (in the app manifest)

Hehe. I didn't mean it's dirty code, I mean it's a dirty solution. The launcher shortcut feature is there to avoid cluttering up the appdrawer with icons.
Besides, widget or no widget, the shortcut feature is still useful. Launchers can't put widgets on the dock.

Yeah, Shortcuts, that's the perfect solution, thanks for pointing it out!
I see you learned a lot already about the SDK!
Time to code your app ?

Note: This Kernel is the reference implementation for Galaxy S GT-I9000 (will work also on GT-I9000M GT-I9000T). Other Galaxy S variants will have issues or won't boot.
It also contains the usual stable Voodoo lagfix, and ClockWorkMod as default recovery.
If you don't know how to flash kernels, I recommend the community written guide, updated by Eitam Doodai
Don't forget to support my development effort so I can continue working hard on it
You can also take a look at an additional list of potential features
Other kernels implementing Voodoo sound:
You'll find plenty of other kernels implementing Voodoo sound for your device in this forum

FAQ:
How to get the best sound quality ?
The best quality for headphone is obtained:
1/ by setting the Android digital sound level to the maximum or close to it
2/ then using the new analog level to choose the sound pressure that suits your needs
This way, you will get the lowest hiss, best signal-to-noise ratio and lowest distortion.
Original post:
Hello
My first bounty, lagfix is a success so here I am again!
Galaxy S line phone have a few sound issues and as a sound junkie I'm working on improving things with Voodoo sound
Those are new features, exciting capabilities your phone didn't had before
Galaxy S phone is at the top of the line about sound capabilities because it uses a high end Wolfson WM8994 sound codec.
That's why it's worth it.
I receive already a lot of a few feature asking to fix things, and it's not what i intended to do.
Your turn!If you have a feature request or suggestion please
- explain it in this topic
- tell how much you can support the dev effort.
I can be crazy features request. Who knows, sometimes crazy stuff can be done
Then I'll do my best to work on it and you'll vote with donations if you are satisfied with it.13I digress... but hey supercurio are you developing/ planning to develop an app similar to voodoo sound for the Galaxy Nexus? Publish it and I will be the first to grab it from market.
Yes Galaxy Nexus will receive Voodoo Sound improvements!
I started the research phase but didn't actually developed it yet.
Features planned:
- Analog headphone amp
- Mono switch
- DAC high performance mode (instead of default: low power)
- Speaker tuning: a bit more bass.
As usual: no ETA so please don't count too much on it as long as it's not actually released9Hi dear sound lovers.
The compilation of your feature request was so promising for me that I suddenly couldn't resist to write some Voodoo sound code
So there are already 2 commits related to Voodoo sound:
Headphone amp gain :
http://github.com/project-voodoo/linux_gt-i9000/commit/62e580cd4de97ec0039bf22a297d415f0f986a95
First usage of the parametric EQ: an anti-alias filter for bright headphones
http://github.com/project-voodoo/linux_gt-i9000/commit/df44533e336c5fde76a0912ad1c68d5f08f38e08
The second one may become obsolete once I'll get total knowledge of the WM8994 sound codec, sound driver and Android sound system internals.
And, you guessed, i very much plan to do that!
Now about the Bounty
1/ Mic sensitivity
This is the big winner of this bounty contest
Both in term of requests and amount. Logically, I'll work on this one first.
Expect it to be included in first or second Voodoo sound release.
Of course this enhancement will need to be done very carefully. I'll take the highest care not disturbing voice calls, voice memos, Shazam/Shoudhound song recognition.
Because I already studied the subject, I can tell you that people who know code may find the patch very short.
Most of the work will consist to elaborate ideal settings for every possible situation.
From filming insect's buzz :
To capturing music video during the latest Deftones live show
If default are not good enough, I'll implement more complex code but will propose a usable interface to control it.
ETA 2 weeks

2/ True line-out
I don't have yet the confirmation it can be done yet, but as it's a requested feature I'll study it and you know that if it can be done... it will !
If the hardware don't allow a direct line out from the DAC bypassing the headphone amplifier, I will improve the sound quality of the output anyway.
The very first release will already allow you to set the output gain to the standard level you expect from a Line-Out. This will resolve most headaches currently caused by the fact that the default output is very quiet.
asked by: morfic, eeyunopper, NeronLux
3/ Headphone amplifier gain
Yes, some headphones needs special capabilities because
- Their impedance is high, sound is too quiet
- Their sensitivity is very high, and you hear too much hiss.
Sensitive in-ear tend to become the norm and because of their isolating nature you hear even more this annoying hiss.
Headphone amplifier gain is the adequate answer to these 2 problems, and if it appear very simple, device in our digital era are extremely rare!
Now Galaxy S will be part of this ultra-elite club.
You planned to buy an expensive external amp because you thought your beloved headphones sound bad? Think again !
− however you can think about my donation link −
4/ 5-band Hardware Parametric EQ
This one will be totally awesome. Too bad a system-wide EQ is not part of Android.
Will combine
- sound quality: +-12db adjustment without saturation or distortion
- with the best power efficiency: use no battery.
5/ Radio Noise
Will probably be the most difficult to archive, but I already have some ideas about it.
However, don't expect a "perfect" solution.
asked by: stranger812, Aj12
6/ iPhone headset support
Want to use iPhone IEM+mic on your GT-I9000? You're not alone!
asked by: many people.
7/ Call through headphones
I don't understand why you cannot do that. Do you?
Looks obvious but may require some profound changes in several software and hardware layer... or not.
Not studied yet.
asked by mcmac7, darkstar2k77. Maybe more people.
8/ General sound quality
Optimizing the sound quality and squeezing the best performance out of the top-notch WM8994 hifi audio codec is the main essence of this project, by a sound lover for sound lovers.
Count on me to make this phone the best Android phone to enjoy music, if not one of the best mobile audio source in all categories.
Is it ambitious ? Yes but thanks with the Wolfson Micro high end hardware present in this phone you could be surprised
asked by dsellers2
8/ Bluetooth gain & A2DP streaming issues
Bluetooth stereo is not audiophile's favourite but sometimes it's so much more convenient!
I'll study and also improve this way of listening to music.
asked by FloridaK and TheTodFather .
9/ Specialization effect for headphones & Crossfeed
One of the first version will include support of the hardware 3D effect.
In my opinion, most effect called "3D" something are pure crap. This one is the exception because it's able to improve soundstage and preserve musicality at the same time.
True crossfeed will be trickier to get done, but nothing is impossible. Once again, this is a bout system-wide solution that work on every sound source.

Standard practice when you develop in the open:
- dev branches, where you publish work in progress as often as you want
- stable branches, where you publish what correspond to stable releases, distributed for other people who can reuse your code safely.
Benefit with dev branches is that you get comments and suggestions, even sometimes bug reports from developers following your work, well if the work in question is worth it of course. But there are a lot of people in forums, including silent people who only send mails after reading code.
In stable branches, you publish tested validated code for releases.
Publishing work with SCM with git and an open development model help improving quality and security of stable releases, ask Linus!
