Is the conversion chip on the S3 responsible for driving the headphones, or is there a "power chip"?

Oops, there is a power chip.

About Android-specific USB audio:

"As of now, the standard Android releases do not include USB host support. Samsung decided to add this feature on their own. The Android folks are working on a funky USB dock protocol that works over USB (sort of like what Apple does) that, frankly, most of us developers think is stupid. There is certainly a push to put USB host support for standard devices (like audio, keyboards, etc.) into the normal Android releases."

[Galaxy S III General] Erahgon:
Yes it is actually. Yank, in his thread on swap has a good reason not to do so.

Electronic storage and SSDs have far fewer writes to sectors, before the sectors are unable to be written to. The external SD card can be replaced very easily, unlike the internal SD card.

[Galaxy S III General] danba:
I don't have JB yet. Using digital USB audio out, I don't think there is any improvement in term of SQ.

However, in the future, I expect Android modders/developers will enhance the Android USB audio feature like Amarra, Audirvana, … for the Mac OS.

I've also been trying to get my sgs3 working with my car stereo via usb audio. Ive gotten it to work but like a flash drive, ie the car stereo just reads all three music media in the phone and the stereo has direct control of these files. I'd rather use my media player to control my music.

Would you have any idea how I could do this?
[Galaxy S III General] danba:
A digital audio system is composed of:

. A storage module: Music is stored in file as a series of bits 0 & 1 with different encoding formats (MP3, WAV, FLAC…).

. A player: The player decodes the bits 0 & 1 to PCM digital audio signals.

. A DAC (Digital to Analog Converter): The DAC converts the PCM digital audio signals to the original analog audio signals.

. An amplifier: The amplifier amplifies the analog audio signals.

. A speaker: The speaker restitutes the music.

Your current stereo car system:

SGS3 as USB storage >> car stereo’s player > car stereo’s DAC > car stereo’s amp > car stereo’s speakers

If your car stereo has analog line in, you can bypass its player and its DAC with a SGS3 + USB DAC:

SGS3 file system > SGS3 player >> USB DAC > analog line out >> car stereo’s amp > car stereo’s speakers
[Galaxy S III General] Agaranda:
Could you tell me in what order Poweramp's and Shiya's settings works?

Thanks in advance,
[Galaxy S III General] danba:
Sorry, I don't know.

I use a stock Galaxy S3.
[Galaxy S III General] Erahgon:
A simplified representation:

Digital file (mp3, m4a, etc) -> PowerAmp music player (decoding, software EQ and effects) -> DAC (Wolfson) and it's controlling parameters (i.e. using the Siyah sTweaks sound control, voodoo sound, or whatever else) -> output to headphone jack.
[Galaxy S III General] elfary:
It's called extrapolation. And experience.

Let's see when Supercurio, Goldenears or other skilled folks do measurements...

But i can safely bet with you a few rounds that stereo crosstalk of the S3 will be higher than -50 db driving a 16 Ohm load (where iPhone 4 has -72db and iPhone 4S -66). That middle of the road crosstalk is fine for cheap in ears but you can sense it with cutting edge in ear monitors (customs, Shure SE535, WestoneUM3x, Audeo PF232).

Samsung record book regarding crosstalk is not what i'd call encouraging. Never has been. Actually is the weakest link of their implementation (when they don't screw the output impedance). I think they engineer toward the masses not toward the excellence in that very regard called headphone out sound quality.

What i have no clue is about output impedance of the thing.
[Galaxy S III General] SiNJiN76:
Posted this question in the wrong thread yesterday...:D

"So, I read that the GS3 will have support for APT-X? or is it ATP-X? Hahaha. Anyway...is that something worth looking forward to? Due to that, I've been looking at the Samsung HS3000 dongle. Reviews for the dongle seem good for the price it is selling at (25 - 30 Dollars)."
[Galaxy S III General] celsior360:
Me three, as my SG2 has bad quality, was better after download the equalizer app.
[Galaxy S III General] eeyunopper:
Well, i'm quite happy with the quality of my S1 using ATH-ES55's as a back up to my (5th Gen) ipod, so as long as it's no worse than that i'll be happy. I'd go for the iPhone, if I hadn't invested so much time uploading my music to Google Music.. :-) The One S is also on my shortlist, but based upon GSMArena reviews only. That SIII Screen looks a beauty though...

Thanks for the info.
[Galaxy S III General] elfary:
For those interested...here goes an interesting article about the output impedance of a headphone amplifier.

http://www.benchmarkmedia.com/discu...-sonic-advantages-low-impedance-headphone-amp

And to drive armature headphones the relevance of the output impedance is bigger.

Again remember that the audibility of issues is directly related to the quality of the headphones. Top tier ones have the ability to reveal what cheap ones can't.
[Galaxy S III General] danba:
Like the overwhelming majority of factory or stock Android devices, with the exception of the Archos G9 tablet and the developer-targeted Texas Instruments Blaze tablet, the factory Linux-powered Logitech Squeezebox Touch does not support USB DACs.

The USB audio is enabled manually on Squeezebox Touch:

http://www.digitalaudioreview.net.a...able-usb-audio-output-on-the-squeezebox-touch

The latest method uses an applet which allows a custom kernel to be installed and provides menus to select the audio output device.

This custom kernel can support 24-bit/192KHz USB DACs. It can also support asynchronous USB DACs which sound theoretically better than the legacy adaptive USB DACs.

[Galaxy S III General] Erahgon:
The S3 is capable of playing FLAC files with high bitrates. Now, any analog connection comes with colouring and losses, and the DAC matters a lot as well.

Lets say your setup includes a great sounding set of studio monitors and an amazing audio interface which they are connected to. Ideally, you would want all the digital to analogue converting to be done by your interface's DAC - as it gives a isotonic sound when paired with your studio monitors (i.e. great sound regardless of the source - phone, mp3 player, computer etc) as they all provide the interface with a digital signal to convert. Also - output impedance, power to drive the speakers and subsequent losses, are now, not a factor, as far as the phone is concerned.

You get speakers out there which accept USB audio signals, which, with this capability unlocked, you could plug directly into and take advantage of their high quality sound.

Hope this explains everything adequately. Feel free to correct/amend!

Cheers!

Like a PC or a Mac, an Android phone / tablet is a digital audio system.

An Andoid device, running on a kernel with the USB audio feature activated, can output the PCM digital audio stream to an external USB DAC & amplifier, much more efficient than the internal DAC & amplifier.

Letting your digital audio go through USB bypassing the phone's DAC should also save some battery juice I believe. And DAC + AMP that you would use in this scenarion, would have its own power source.

[Galaxy S III General] Kendoji:
LOL I strongly suspect he just used the headphone out rather than USB OTG, though I'd love to be wrong.

If USB audio works out of the box I'll go buy an S3 tomorrow.
[Galaxy S III General] NZtechfreak:
My E17 failed with the S3 I used two weeks ago (pre-release firmware etc) - sound was routed through loudspeaker.

Today with my release firmware one the E17 still doesn't work, however sound doesn't go through the loudspeaker anymore, and furthermore when I go into the stock player and try to change audio effects it says "not available for line out connection".

Upshot is I believe USB audio may very well work on certain USB DACs... Would be great if someone could try out earlier FiiOs like the E7 which appears to be much more widely compatible than the E17 (for example E17 doesn't work with Nokia N8 but others like the E7 do).

[Galaxy S III General] TYA.:
PowerAmp is not special here.

About Siyah dac direct option. In Siyah kenel , inside Stweak field you can see Audio tab.

Four last lines is very importance.

. FLL tune : the way dac generate clock to helps cpu idle

. Dac oversampling : help improve much sound quality when play HD track (24/96)

. Dac direct : output direct sound , not through output mixer.

Clearly much more improve sq. Can confirm by switch on/off

(Ouput mixer block is between dac and oitput interface)

Decorder of NeutronMP is better than Poweramp , cause it use 64 bit resolution for resampling HD tracks (normal track is no resampling action, android core can handle it)

I have a O2 + ODAC combo to play with my Galaxy S3. Use Neutron MP with success.

Since I have many HD music files (24bit / 96khz), I wonder if the Android can stream the files with 24bit resolution for the ODAC, or it downgrades to 16bit / 44khz even though I´m not using the phone´s internal DAC.

Anybody knows that for sure?

Thx
[Galaxy S III General] Kremata:
I found that Poweramp has more clarity in the sound. The instruments seems to be better separated. The bass is also more fast/precise(or less muddy).

Neutron on the other hand is more warm. The instruments mixed together for a more "musical" performance. The bass is a little more wide but the high are a little less screaming.

Conclusion: Poweramp is more suitable for a audiophile style listening. (I turn off all the lights and listen to the music at mid/high volume)

Neutron is more suitable for output on the soundsystem or with earphone while driving my motorcycle (high volume)

Tested with Ac!d Audio and Sennheiser IE80

Noozxoide Line-Out-Monitor

Xlimiter = ON - Effect Strenght = Moderate

Psychoacoustic = ON - Effect Strenght = Medium

Balanced X-EQ = ON

Digital Preset = Audiophile

LogicSurround = ON - Room Size = Room

Poweramp

EQ set to ROCK

Stereo X = Middle

Neutron

EQ= ON
[Galaxy S III General] UXELLR:
I would think if we are going to compare two players , it is better to have flat settings on both.

Or else there will be to many variables in the equation. For instance, of course there will be difference, if one

player has Rock Preset or EQ on, while the other player don't.

There also should be volume matching. Volume will affect the way we percieve sound.
[Galaxy S III General] Kremata:
I would normally agree but in this case Poweramp have more settings than Neutron so it is something to consider if you compare the two players.
[Galaxy S III General] rab1412000:
I agree. The best player sq wise should be the best on flat settings. For me this is neutron bar none. More clarity, better soundstage, more extended highs. You really can't eq clarity and soundstage so this is my preferred media player. Poweramp and stock sound muddy, muffled by comparison on flat. I can probably eq them to sound a little similar, but this leads to a more synthetic sound quality.

General opinion is that Power Amp is the best .

But search XDA multiple threads on audio may give better/more information .

jje
[Galaxy S III General] WiR3D-kNiGhT:
I dunno about that, general opinion is power amp has the best UI and functionality, but Neutron has the best SQ (so says me and a bunch of other people at head-fi, and I tested about 9 players.)

This was about 6 months ago so some stuff could have changed.

Best SQ from best to worst:

Neutron Player

Player Pro

CM9 stock

Same: cubed, MixZing, DoubleTwist

CM7 stock

----probably dog turd

N7player

Power Amp

I use neutron, but Player Pro is clearly the best of both, unfortunately neutron still has enough of a margin on SQ to keep me using it.

As for settings, thats minimal, and stuff like resampling and 64bit processing in neutron for example switched on, the same goes for other players if they have it. But EQ or surround expanders turned off.

[Galaxy S III General] rab1412000:
totally agree. Even if audio can be very subjective, there are still certain generalizations that can be made. And the fact that neutron has the best sq is one of them.

The s3 has lower volume due to some eu restrictions that limit max volume.

This can be easily corrected by flashing kernels that support audio tweaks like perseus and siyah.
