[DEV] Voodoo Sound for Transformer v1 for 3.0.1, 3.1. Feature requests and discussion

Hi everyone!
Asus EeePad Transformer hosts a very nice audio codec by Wolfson that powers both the headphone and speaker output.
Its the ultra low power WM8903, implementing a midrange DAC (Wolfson-scale) that outputs a clean and musical signal, and my favorite Class W headphone amp, that gives a clean controlled and accurate output, and is able to drive full-size 300 Ohms headphones without distortion.
The transformer audio power stage is not as powerful as other device I tune so at maximum volume but I'm sure you'll be surprised by the capability of this amp if you compare it to any other mobile non-Voodoo device.
I might limit the maximum gain to +3dB to avoid saturation.
Voodoo sound is:
A control Android application
- Free version (semi broken on Honeycomb ATM, will fix soon): https://market.android.com/details?id=org.projectvoodoo.controlapp
- Plus/Donate version: https://market.android.com/details?id=org.projectvoodoo.controlappdonate
Plus version gives the ability to get full Voodoo sound implementation without depending on a custom kernel. Root is required to load the additional driver.
Free version requires a kernel implementing Voodoo sound GPL patches as you'll find plenty on XDA.
Features of the v1 :
I'll be very accurate and describe the exact change so far.
As usual, you get what you see.
What Voodoo sound driver v1 does on transformer is mapping volume to the headphone amplifier hardware control.
In the standard configuration, here is how it works: Most time only half or less of the Dynamic Range of the DAC is used (depending on the current output volume) by trimming the signal amplitude in a digital way.
What brings the driver v1 is a maximization of the digital volume, so the system works really on 16bit instead of 12 or even less at low volumes. And instead of that you control directly the analog gain of the Class W headphone amplifier built in the codec.
It allows to get more powerful sound, like to drive full-size high-impedance headphones at desired volumes, but for most people using sensitive headphones (same for in-ear) the sound is improved because there's far less hiss by reducing the analog gain.
When you reduce the noise level, the sound is more clear and defined.
I have some more leads in development for this codec, like:
- better oversampling quality (128x oversampling, require also clock reconfiguration on the SoC)
- alternative digital filter to reduce the very high frequency intensity ( > 20kHz) in order to reduce the listening fatigue.
WM8903 doesn't support digital effects like parametric EQ or 3D effect so I won't be able to activate that, but there's still some headroom to improve the quality and neutrality of the response, audiophile-style
Here are measurements I made without any modification, on 3.1:

Planned features
- Better SRS presets for the speakers
- Maybe some volume boost for speakers if possible with reasonable quality.
- If usable and providing sufficient quality: customizable EQ & 3D effect using SRS software engine for the Headphone out.

Screenshot of the first version, thanks jjsoviet

this looks great.

SO its a better sound driver so to speak?

Eyup.
Actually, it pains me to know that my Transformer now beats the crap out of my Zune HD in some areas, like soundstage and overall dynamics. Whatever voodoo hoodoo shmoodoo Supercurio's cooking on his kernel kitchen, I love it.

Yes its an additional driver built around the existing one in order to use the audio hardware in the optimal way.
Most manufacturer are happy enough when their device output sounds, but in many case the result can be improved, sometimes vastly.
And I must say.. its particularly interesting when the audio hardware is made by Wolfson, because you know the result can probably reach audiophile-quality levels!

Will this also help the tf's speakers? I've beem ok wirh the headphones but not the speakers.

Free version requires a custom kernel implementing Voodoo patches.
The first custom Kernel supporting Voodoo sound is this one, by Clemsyn! http://forum.xda-developers.com/showthread.php?t=1109630
As stated in the description today the free App is semi broken (the manual volume slider crashes on Honeycomb, but the volume key mapping works)
I'm working on an update ATM.

Voodoo Control 1.0.7 finds the driver here: http://twitpic.com/5ei07e (only the volume key mapping works ATM)
If it's not detected it means your kernel actually running doesn't implement Voodoo Sound.
Note: Clemsyn published the kernel very recently!

Just tried your apk and it's pretty impressive, sound is clearer and cripspier when I play dungeon defenders with my kids and it seems louder than the Gtab now. Didn't even think my transformer will sound like this

You're talking about the headphone output right?
Because the speaker output is not (yet) affected. I hate to contradict people hearing improvements but I must sometime by integrity

Just dl'd the free version from the market to run with Clemsyns kernel and it seems to be working nicely. Thank you very much for the hard work.
Couple of requests would be:
1. Mic gain control
2. The stock music player always pauses when the screen is off. When using headphones you can hear what sounds like the headphone feed being turned off...

The Power of Suggestion is a powerful tool. Use it WISELY! LOL!!!!

Hey SC,
First, awesome job on getting this to Tf (bought the donate app awhile back for my Galaxy S, and now you're making me ha ppy with Tf).
Main feature request from my side would be mic sensitivity, this time the other way around was too sensitive on galaxys, needs pumping on tf. Also, if anything could be done to the internal mic quality on software level, would be awesome.
Thanks!
On a side note, I was sure i heard an improvement with speakers after installing control app, but that might be placebo effect.

Okay I'll take a look.
I'm already experimenting with Speakers ATM, messing with registers.
It seems its possible to boost a little bit the speaker output, but really only "a little bit": +2dB
I doubt anybody will notice, but it's still better than nothing.

Introduction
Do you like to listen to music? Or perhaps seeking to improve the audio performance on your Android device? :victory: Time you try raccoon audio enhancer
Raccoon Audio a.k.a R.A
What's Raccoon Audio?
Raccoon audio is audio optimization applications in the audio device is a modification and combination of multiple applications with the interface of the sound enhancer noozxoide EIZO-rewire ™ PRO simplified and modified to incorporate some engine sound enhancers like beats audio, dsp manager, SoundFX, dolby and some other.
What distinguishes Raccoon Audio sound enhancer with other applications?
-The difference is more RA refers to the optimization of the sound on your android device and maintain the stability of the supporting hardware audio device.
-Besides installing the RA in quite easily.
-Install RA without using CWM,
-Install RA without a push into the system,
-RA can run on any device that unroot,
-RA is not at risk of brick or bootloop,
-RA is more compatible with almost all ROMs and android devices, but it is also compatible with most music players and when you have an android device other sound enhancer, RA tend to be more friendly
-Effects of raccoon audio not only do you feel when playing on the music player, but the effects can be felt when you play back audio in the file browser that supports audio player, the youtube app, the internet browser
In any android version can be active RA?
Starting from gingerbread to jelly bean, for froyo RA can not run.
What privileges audio raccoon?
Raccoon audio smoother and more compatible with the music player or audio player such as youtube, browser and others. Besides the interface more attractive (for ics). Using the engine of sound enhancer that has been optimized so it is suitable for audio and raccoons can be used universally in different ROMs and devices.

FAQ (Please read before running raccoon in audio)
Q: RA only smaller?
A: Yes, RA is a combination of several audio enhancer such as I have described above, to our use of noozxoide interface, but we simplify and modification. Our consideration is a small file so for those of you who have a small memory can also be shared in the RA, in addition to that we have some other considerations especially for low device.
Q: Is the RA safe to run?
A: Safe, because of the way RA is relatively easy to install and does not cause brick, bootloop when you install applications such as audio enhancer should use CWM, or push to the system. Besides applications like RA and other articles on tips droid always through testing stages before publication so that readers tips droid safely use our applications and tutorials. RA is also safe from viruses and mallware (tested with some antivirus on your PC and android and declared clear of viruses and mallware)
Q: RA can run smoothly on the android version is it?
A: Our RA test runs smoothly on the stock ROM and some custom ROM from several different devices both vendors (Samsung, LG, Sony, HTC, Hi-Sense) and type. In Gingerbread, ICS and Jelly Bean goes smoothly, but on froyo not work.
Q: After using RA why even a small sound effect almost no change?
A: In addition to RA, running or not depends on the compression of the song, when you use an uncompressed song irregularly, RA can not run optimally.
Q: My RA force close, what's the solution?
A: We minimize these events, some tests we did, but for some applications audio enhancer, I have tried to make the RA is compatible with other sound enhancer, but in some cases RA sometimes can not run smoothly with sound enhancer, if it happens, you should take the solution is please to freeze sound enhancer you have used before.
Q: Is the RA only have an effect on the music player?
A: No, the RA will provide overall audio effect, like on youtube application, browser, file manager that has audio player, ringtones and other (including voice when you call, but only a small effect to reduce noise so that the sound can be heard clearly when your phone, it also depends on your signal and your listener while also mic your speaker and your speakers)
Q: Is the RA can damage hardware audio?
A: RA helps you to optimize the audio hardware and software you. If you do the proper setting in RA, the audio device you will be more durable and optimal than not use RA, but if you are setting up the force in excess, will cause damage to your audio device.
Actually not only RA, but all applications enhancer and music players can damage your audio hardware, if you make the wrong setting volume dimaximalkan example, setting dimaximalkan without tolerance. Without the application of RA or audio enhancer memaximalkan even if you force a continual and regular basis, I can guarantee your hardware will be damaged, but it is less convenient when you hear the organ and can damage your hearing. DWYOR.
Q: How do I set RA is best?
A: For this question I answered "relative", we suggest you to try to do their own personalized settings, and the ability to tune your audio device. If you are confused you can find references on the internet how to set up the equalizer on the right and the best android.
Q: After using RA, why is music to be large or small volume suddenly?
A: Make sure you play good music and not compressed extrem, also make sure the bitrate of the song, make sure your music player and speaker capabilities of your audio device. Also make sure the RA runs and does not crash with audio enhancer you use before you install RA. Setting RA also affects the quality of the sound produced.
If it happens that you take is a solution uncheck audio compression options

once you try it, please to write a review

Looking great :thumbup:

can anyone willing to give a review about the raccoon audio again?

This is indeed a wonderful tool to boost the audio experience , but there is a problem that while changing settings sometimes the volume suddenly increases which is painful to ears. If this thing is solved . Its almost perfect.

Testing this out. Will report back. :thumbup:

Mean while i flashed Galxperia v3 http://forum.xda-developers.com/showthread.php?t=2206406 with clear audio+ and Bravia engine as extra mods with adipat's kernel http://forum.xda-developers.com/showthread.php?t=1931478
Then it happend as a total accident as i was browsing through forums here at XDA i came to know about a player then unknown to me n7 player with custom settings [http://forum.xdadevelopers.com/showthread.php?t=1537938]
i decided to give it a try with custom Equalizer setting 12,2,4,1,4 bass boost off , srs off. for testing by played The Black Eyed Peas - Boom Boom Pow my default bass testing song and i was literally blown away. finally after quenching my bass thirst i was finally happy with my s advance.....then............
Mirracle :2
one day i decided to test newer versions of custom roms for our device and came across pure vanila V5 Build 2 http://forum.xda-developers.com/showthread.php?t=2182697 with Awesome Beats & Dolby Mobile..and i paired it with cocore 6.2 kernel ...With Beat's boost preset in ''Moderate'' setting and equalizer in ''Bass booster'' profile i attained ultimate bass niravana even with stock head set...
so guys i humbly suggest you to try these mods and i i guarantee you will feel the difference.. feel free to give your audio experiences and experiments...
PS:Remember to turn down the volume to 80% to avoid distortion if you are using stock or low end headsets
my sincere thanks to all original developers with out whom this experience would have been impossible and thank god for android customization capabilities[/LEFT]

Wow such a long story..nice share bro :thumbup:
When I bought my s advance I didn't really care about audio quality, I don't know if this handheld have own dedicated sound processor or not.
I use a song from beyonce - irresistable to benchmark all google play audio apps which I found playerpro is the best second player, the first best is neutron music player.
Try neutron, you will know.
IMO a handheld that using a software to emulate best audio quality is no match with a handheld having its own dedicated sound processor..I mean a real sound processor separated from main processor.

Nice fresh player
Wow, a very different design approach, I love it so far.
Some questions -
1. Does this player have a sound limiter enabled to avoid distortions?
2. Folder view - I like the list but would prefer a file browser method with file Hierarchy method. Similar to file managers.
3. Folder sort options - Ability to sort files in folders by date added - really helps as i add a lot of music randomnly to different folders, and when the folder size increases, this helps a lot.
4. Song/ Album art downloading - is this enabled? would be great if we can get album downloads with manual search and high resolution results.
Will definitely be keeping my eye on this player.

Hi, rmdeathwish.
I'm Jay Lee, the sound designer of PlankTone Music Player.
I used a lot of other techniques to avoid clipping and distortion instead of a limiter.
Because the limiter could cause unclear sound.
Other features you want will be added soon.
Thanks for your feedback.
I hope that you can enjoying your listening with PlankTone!

[APP] Stealth Audio Player - play audio through earpiece

Usually, there are two ways of playing music on Android device. You can either use your headphones or a speaker. But how about a third option?
The purpose of this app is to enable the users to listen to something when they do not have earphones and they don't want to use speakers.
When you are with someone and you must listen to an audio file e.g. a voice message, etc. you can now listen to it using your device's earpiece (from which you hear phone calls) using this app.
This is useful not just for usual audio files, but also for podcasts, and comes in handy for when you forgot to bring headphones and do not want to disturb those around you. Stealth Audio Player enables you to make good use of the tiny speaker to listen things which should not play from the main big speaker.
Download from Play Store:​https://play.google.com/store/apps/details?id=com.appsbyusman.stealthaudioplayer
FEATURES:​
Plays any kind of Audio from the earpiece of your device.
Plays Videos on screen and their audio is routed through the earpiece.
Folders Browser lets you locate specific files.

Just what i thought to ask you as I made a jump here again. Now that's everything i could desire. Thanks again

I'm glad that you like it

A couple of ideas that i could suggest to you to make this lil' app just perfect in every aspect, is first - adding an option to search music; second - add a side slider to reach alphabetically a certain letter.
I'd like to premise that these ideas could be useful just in my opinion, where i don't wanna use this as daily player obviously, but with more than 50 songs the research become huge and hard... What do you think?

A+ for the idea Nice, light-weight application. May it be useful to create the sticky notification with the control buttons and the name of the track? It will be shown when the app is running, and the song is playing. Several times, I have minimized the application instead of closing it or at least stopping the playback, put the phone in the pocket, and the music continued playing

Thanks for the feedback.
There is already an option to search music. You can search by Title, Artist, or file name.
About the slider: That would be very useful. I also want to implement it, and I will probably bring an update about it but right now I am working on making the app crash free for all devices.

The nature of this app is that we only hear the audio while the device is attached to the ear. In this position I don't think there is a need to bring features of full fledged music players. The users will stop hearing anything as soon as they are able to interact with their devices so there will be no use of bringing the notification controls.
This app is not a music player, it's more of a utility for hearing the audio in a different way.
However, I do have plans to better manage the minimizing of the application. This will be addressed in near updates.

You're right, didn't noticed the lens icon in the upper right space. Maybe because i didn't reboot the phone after the last update..? Anyway I've seen that the list of available mp3s have to be reloaded by filename every time that the app is launched. You think that a preload of the list like a normal music player could ever be made someday?
Thanks to you for the creation of this app.

I have been trying to preload the data with different approaches. But it's getting a little tricky. I am gonna try something new tomorrow, which will hopefully make it A LOT more stable, and I am positive that the files will show up faster and with more stability than all previous version.
An update was also published today (evening) which addressed several crashing errors which the complainants are reporting to have been rectified now.
