So, how do you explain that a Studio Master 24bit music file can be played on a stock Android-powered Samsung Galaxy S3 with the USB Audio Recorder PRO application thru a 24bit-capable ODAC?

Don’t trust anyone on the Internet!

The person who says you "The custom API iBasso created bypasses the crappy kernel on Android thus you get the full benefit of the Sabre DAC" is quite clueless about software.

How can an Application Program Interface bypass the kernel???

He should at least read and try to understand some Android basic concepts

The iBasso player (at the application level) uses a custom iBasso audio driver (at the kernel level) specifically developed for the Sabre DAC.

PowerAmp or Neutron (at the application level) uses a standard Android audio driver (at the kernel level) developed for some common basic DAC (i.e. this driver doesn’t exploit all the features of the Sabre DAC).

That is awesome, certainly worth the buy then. Thanks DanBa!

So far, like the quad-core Exynos powered Galaxy S III, the new quad-core Exynos powered Samsung Galaxy Note II can work with the FiiO E7, the iBasso D12, Leckerton UHA-6S MKII, the ODAC, … ; has some issue with the HeadAmp Pico; and doesn’t work with the FiiO E17.

 

So, in regard to the USB protocol, the behaviour of the Galaxy Note II is likely identical to the behaviour of the Galaxy S III.

The iBasso player (at the application level) uses a custom iBasso audio driver (at the kernel level) specifically developed for the Sabre DAC.
PowerAmp or Neutron (at the application level) uses a standard Android audio driver (at the kernel level) developed for some common basic DAC (i.e. this driver doesn’t exploit all the features of the Sabre DAC).
I agree re, eveverything has to pass thru the kernel.
Also there are custom kernels out there such as siyah and boeffla kernel that has greatly enhanced the SQ and has provided hardware control of the built in Wolfson dac. I'll try to find that ibasso dap and do an a/b with my modded kernel s3.
I do agree with lee though that the stock Android kernels do not sound good.

In order for it to do such thing it would have to bypass androids native kernel otherwise it is still limited to 16/44 and thus that means your music is being downsampled. In fact Neutron and Power Amp are capable of 24/192 playback the fact is android is not and that is why they are limited to 16/44. Do some research on it. ibasso has managed it by bypassing the kernel and using their own custom made driver directly to the Sabre DAC.

A computing kernel is the basic component by which applications and the OS communicate with hardware. Everything has to go thru it as it provides the instruction code for everything.
There is no way to bypass it.

Dacport LX is working with Note2 , using audio recorder pro (limited to 24bit only!!!), without any USB HUB!!!!!!

All I want out of Android is to give me a UI, access some files (local or remote), and feed the bits out the USB port. That's what its good at. Get the bits and pass them through untouched. (I guess I might trust one or two select softwares to mess with the bits if they do it in floating point.) At that point I now have a choice of dozens of external DACs. (Though currently only a few phones with proper USB OTG support for external DACs). 

 

Less than 0.1% of music is natively more than 16/44. Up-sampling doesn't add any information to the music. And I believe this thread has reports of the USB OTG chain handling higher bitrates anyway. Maybe people will now start talking about jitter but that can be solved with a simple buffer and very slight time delay. 

 

I'm sorry to slam the iBasso but its a brick that runs an increasingly ageing version of Android. USB OTG and external DAC are the future. And while it requires two boxes their total weight and volume can be less than the iBasso. At what point will people admit its obsolete... 1 year... 2 years... Well who knows, people still swear by vinyl despite constant angular velocity meaning each track has less information than the one before it until the inner tracks have half the information.

Wishful thinking :). You'd have to use something along the lines of the DACport LX to even start to compare to the DX100 and you also have to take into account your amp section as well. So in the end, I highly doubt it. Pairing a good DAC and an amp will be bigger than the DX100 and most likely not sound better still ;). My DACport LX with the UHA6 MKII were on par with the DX100/T1 amp but still not better than that pairing. It took the Triad with the DACport LX to crush my DX100/T1 combo and even then I still find the combo still comparable in some aspects.

Just out of curiosity, tonight I flashed CyanogenMOD 10.1 and then installed USB Audio Recorder Pro.

Why?  When CM10 doesn't work with DACs?
Well, I read that USB Audio Recorder Pro had special drivers for the kernel.  I was hoping it would work better.

 

So when I ran the app without the USB-OTG cable plugged in, it complained that the device needed to be connected first.

So I rebooted.  Connected the USB-OTG which is connected to my UCA202 DAC.

Then started the app, which advised it was now connected via USB.

Located an MP3 which the app complained about.

Then located a FLAC and clicked "play".  But nothing happened.  So either I don't know how to use the app, or it's not helping that I was on CM10, or something else is up.

 

Update... I was playing a bad FLAC file.  A proper working FLAC played just fine.

I think you should ask the developer on his KVR topic:

or invite him to come here.

I agree too.
There is no stock OS / kernel natively optimized for audio because audio is not considered by multi-purpose device manufacturers as a consumer target.
Luckily, there are third party developers who are improving the audio features like Supercurio or Siyah for Android, Amarra or Audirvana for MacOS
 
The current stock Galaxy S3 could deliver a cleaner USB audio stream by just modifying some configuration parameters of the kernel scheduler and of the ALSA USB audio module.
 
"An interesting example is the HRT music streamer II, it IS asynchronous USB, but it is still very sensitive to what happens in the computer. On the SAME COMPUTER I can make simple changes to OS scheduling parameters and get a huge difference in the sound. At one end of the scale its dull, lifeless, no depth at all, at the other end of the scale it is wonderfully alive, dynamic, huge depth etc. And all this by just changing a few numbers, NO change in hardware at all."
