Does it also remove that pre-equalizer for bluetooth in the SamServMode?

Not only headphone's but also bluetooth's sound settings have their own EQ.
PS:Those preloaded EQ is very worse.

Supercurio, let me know if this isn't appropriate here, it is somewhat sound related. I am wanting the ability to record my phone conversations. In addition having a setting that depending on the phone number will automatically record. I.e. if someone calls you from a certain number or you call a certain number, the phone starts recording when the connection is made. I would be willing to pay at least $20 or more depending on the features involved.

Hi guys I am quite "green" here, I am already using Beta4 and I found it very useful thanks for that. I also want to try this sound improvement but I cant install it as update.zip...keeps saying installation aborted!!!
What am I doing wrong? Thanks

+1 for mic gain.

It might not be just a mic gain though... I've noticed that sound gets distorted both when video recording and when just speaking.

When you record a video, my impression is that mainly low frequencies get distorted. On the other hand, when speaking inside a loud moving car, it gets distorted too.

Either way, +$20 from me for the above.

Okaj,

When i plug in a random headset (not the one from Samsung) the sound is super quiet. If i press the button on the headset, next too the mic, the sound gets normal loud and like it should be.

I tryed to change the values in the "Mix TX" menu but it did not help.

Can you help me?

Well this is probably out of scope here, but I really want this 2...
1. Usb host for external DAC
2. ReplayGain for music

Louder in call volume for my UM3X will be nice.......

Hello Everyone!

I'm working on a compilation of all your feature requests an bounties, see you in at least an hour :)

Salut Supercurio!
Comment ça va?
J'ai vu que t'es un Sound-Freak?
S'il te plaît, est-ce que tu pourrais m'aider avec un petit probleme que j'ai depuis que j'ai reçu mon GT-I9000 ? J'ai absolument besoin d'un programme qui me permet d'enregistrer mes conversations sur le disque dur de manière native. Les Amerloques appellent ça un "native call recorder". Il y en a un dans le firmware Froyo du Galaxy S Coréen ( lien ) . Est-ce que tu pourrais soit m'aider à extraire ce petit programme ou bien à carrément l'installer sur mon Galaxy S Européen? Merci beaucoup!

Hi 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 :

If default are not good enough, I'll implement more complex code but will propose a usable interface to control it.
ETA 2 weeks
asked by: crossbone85, BronzedDroid, crossbone85, BronzedDroid, mike.sw, webcrtor, darkflyer1983, efegue, nsgtr34, rafalense, Anduru, Cazador-, GwynBleidd


2/ True line-out

18rca12foot.jpg

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

hd650.jpg
UltimateEars_Marshall_WhiteSM.jpg


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 :p


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
62_thumb_2.jpg

Will probably be the most difficult to archive, but I already have some ideas about it.
However, don't expect a "perfect" solution.

6/ iPhone headset support

133445-etymotic%20hf2.jpg

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

2006_150.jpg


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

330px-Bluetooth_logo.png


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.
asked by cbdrift


10/ Other various requests

- Multi-track recording support by thurtig
- VOIP fixes by magpolson


PS : remember it's a Bounty thread.

Format:
- Feature requested + description
- development contribution

Thanks :)

Looks great I can't wait, just don't let this take away from time spent on reducing lag and improving general performance of the Galaxy S! Is this the order you plan to work on things? Do you have a proposed timeline for the improvements? What did you learn from your phone meeting with that guy, and will he be helping you?

    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

    Here is what I'm implementing for the first Voodoo sound release:

    Headphone amp analog gain:
    Reduce the hiss or give you a much louder output. Configurable from very low levels to very high.
    Already tested with sensitive in-ear very prone to hiss and brilliantly confirmed with Sennheiser high-end 300 Ohms headphones.

    Hardware Parametric equalizer:
    Change the frequency response to correct your headphone deficiencies or to adjust the sound how you like. Use 0 battery and work on every sound source. 100% configurable

    Hardware 3D effect:
    Finally, a good specialization effect. Can improve sound-stage if used wisely. Configurable.

    Here is the link to Voodoo sound source repository if you are curious about it.
    Those are new features, exciting capabilities your phone didn't had before :D
    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.

    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.
    Your turn!
    13
    I 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 released ;)

    The problem I see is that's how you like it.and not all developer do that way.
    I don't mind to share code, but I don't like to share code that I don't tested and controlled for bugs. What you like is to share bugs to. That's the main different between us.
    You think that real time sharing is a good thing, but I don't like it at all.
    That lower the quality of sharing code and it's a wast of time.
    Also if I want to put others code in my code I want to know what it does.
    That's how you make quality code/program that works and have little bugs in them. The way you think is good is just Alfa/beta code that never will be good.

    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!
