GoRave wireless multi-room audio & Android USB audio:
http://gorave.com/

"Any audio content your device can output (except phone calls) can be cast from your GoRave Audio Sender to the Audio Receiver and played on the great-sounding loudspeakers in your space."




Android device > digital USB audio out >> GoRave Android Audio Sender >> SKAA radio link >> GoRave AR5 Audio Receiver >> GoRave speakers








"Most Android devices will work fine with GoRave. However, GoRave depends on the Android software and the device manufacturer.

All devices with Android v5 “Lollipop” will work perfectly with GoRave.

Devices with Android v4.4 “KitKat” and earlier (v4.1 “Jelly Bean” and v4.0 “Ice Cream Sandwich”) will likely play just fine. Your Android device will need to have USB Audio Output turned on in order to play your audio via the GoRave Android Audio Sender. If you don’t hear audio playing on your GoRave speakers, check that the USB Audio Output feature is enabled in your Android OS settings.

Android’s USB Audio Output feature requires “USB Host Mode”, also known as “USB OTG (On-The-Go)” hardware. Most device manufacturers support this feature in their hardware. If your device does not have USB Host Mode / USB OTG, you can still play with GoRave via a music player application called USB Audio Player Pro.

If you’re not sure if your Android device will work with GoRave, try it with a USB loudspeaker or dock. If you can play from your device with USB speakers work, then your device supports USB Host Mode.

Hey Guys,

Finally got my USB DAC to work on my SGS4. It's been tough looking for a cable that has USB charging with DOCK mode on the Samsung phones, so just for reference this is the cable that worked for me.

http://shop.valarm.net/products/micr...er-for-samsung

Quick question for you guys, is there a way on the SGS4 to get PCM out? Is it PCM out in DOCK mode?

Thanks!

AFAIK a few Android devices can send something different than PCM, ie DSD.

I don't quite understand.
If your USB DAC is working with your Galaxy S4, your Galaxy S4 is transmitting PCM streams (PCM streams or "DSD over PCM" (DoP or native DSD) streams) to your USB DAC.




Android 5.0 Lollipop-powered Google Nexus 9 & USB audio:
http://www.engadget.com/products/htc/nexus/9/

http://vaiopocket.seesaa.net/article/409858044.html







Google's Native USB audio: Resampling!

44.1kHz music file > generic music player "Kamerton" running on Android 5.0-powered Nexus 9 > 48kHz PCM stream >> USB OTG cable >> Aurender Flow USB DAC/amp




eXtream's User space USB audio: No resampling!

44.1kHz music file > USB Audio Player PRO running on Android 5.0-powered Nexus 9 > 44.1kHz PCM stream >> USB OTG cable >> Aurender Flow USB DAC/amp



96kHz music file > USB Audio Player PRO running on Android 5.0-powered Nexus 9 (i.e. eXtream's User space USB audio) > 96kHz PCM stream >> USB OTG cable >> Aurender Flow USB DAC/amp

Interesting, I can play FLAC files with 48 KHz, 24 bits and 6 channels, sounding great!

Obviously there is a downmix at some point, but the DAC and the UAPP says 48,000 Hz.

Now that Android Lollipop is out and is listed to having support for USB audio can we use something like this to dock to an Apple docking station?

http://www.amazon.com/Connect-Samsun...ywords=samdock

I have a Nexus 5 with Lollipop 5.0 and would like to connect it to a docking station I have for my old Iphone. From what I understand USB audio is supported on some level with 5.0...

You cannot, as far as I know.

The mentioned CableJive USB cable is a special cable compatible only with old Samsung Galaxy S2/S3/S4 and Note1/Note2/Note3. It is not compatible with the latest Samsung Galaxy S5 and Note4.
In fact, this cable is not compliant with the USB specification, because it is used to transport analog audio over USB (USB is digital!):

old Samsung Galaxy S2/S3/S4 > analog USB audio out >> CableJive USB cable >> Apple docking station

Android 5.0 Lollipop-powered Nexus 5 > digital USB audio out >> USB OTG cable >> USB DAC > analog audio out >> amp >> speakers or headphones





There are a list of USB DAC compatible with Android 5.0 Lollipop-powered Nexus 5 and a list of USB OTG cables at the first post.

For the record:

My NAS is a D-Link DNS-320L
http://www.amazon.com/D-Link-ShareCe...-link+dns-320l


The parameters to access the NAS through the UAPP:

Address (URL): SMB://DLINK-NAS (SMB:// + device's name on my Windows LAN)
User name: guest
Password: (blank)

Since yeasterday working like a charm

Anyway, I think this network section on UAPP could be more friendly like ie. HibyMusic does.

Cheers

4th type of Android car audio via USB: MirrorLink
Enable USB audio on any Android 4.0 smartphone/tablet

music files > MirrorLink-certified music player running on MirrorLink-certified smartphone > 48kHz PCM over RTP/UDP/IP >> regular USB cable >> MirrorLink-certified car head unit: DAC > amp >> speakers








MirrorLink provides the technologies that connect consumers with smartphone applications in a car when driving.

"MirrorLink is a technology standard for controlling a nearby smartphone from the steering wheel or via dashboard buttons and screens. The technology leverages a vehicle’s controls and displays to give consumers access to their smartphone apps while driving, allowing them to be connected and responsible at the same time.

MirrorLink offers numerous benefits beyond replication of a mobile device screen on a vehicle’s dashboard. For example, MirrorLink specifies (1) use of BT or IP based audio streams to and from the mobile device, (2) advertisement, launch and termination of applications using UPnP, (3) mechanisms to exchange data between the car and the mobile device, e.g. location information and (4) the establishment of trust relationships and handling of application certificates."
http://www.mirrorlink.com/frequently-asked-questions
http://www.mirrorlink.com/consumers
https://cert.mirrorlink.com/ProductListing/



















For example, Spotify is not yet a MirrorLink-certified app.

XDA modders have modified the MirrorLink service of some Samsung's flagship phones so that Spotify can be used (i.e. full mirroring).

HRT dSp USB DAC/amp:
https://www.facebook.com/HighResTech

"The new dSp can connect to an Android smartphone or tablet and doesn't require any extra cables or adapters. Just use the included USB micro B to micro B cable and its ready to go.
With its ultra low power consumption, the pair will play for an extended period of time. [under 50 mA]
http://www.head-fi.org/t/647693/soni...#post_11012523
If you have a notebook or computer, the included USB A to micro B cable is all that is needed.

The dSp is a digital Sound processor which includes a high performance DAC and a powerful amplifier. No matter what headphones you listen to, the dSp will make them sound their best."

"The $69-suggested HRT dSp connects to Android devices and PCs."
"The dSp’s UAC (USB Audio Class) interface receives USB audio (PCM) from the host device, including from Android devices running the latest Android 5.0 (Lollipop) OS, which offers native support for USB audio via accessories such as the dSp, said CTO Kevin Halverson. The dSP supports all USB Audio Class 1.0 sample rates and bit depths including up to 96 kHz and up to 24 bits."

High resolution Onkyo HF Player:
http://av.watch.impress.co.jp/docs/n...20_681251.html

A new version of Onkyo HF Player, available in January 2015, can play hi-res music files and output hi-res PCM streams to external USB DAC.
It can also play DSD music files and output DSD over PCM (DoP or native DSD) streams.
Like USB Audio Player PRO or HibyMusic, it has its own USB audio soft driver (i.e. Onkyo USB HF driver).






This is an exciting time as we have a lot of audiophile-oriented music players (USB Audio Player PRO, HibyMusic, Onkyo HF Player) which can bypass the Android audio subsystem and interface directly with the USB host driver.

The famous audiophile Audirvana music player for Mac OS X uses the same framework: it bypasses the Mac OS X audio subsystem so that it can implement a lot of audiophile stuff to deliver cleaner PCM streams.

A gift for the next Christmas: Virtual Reality (VR) headset for music / video / ...







multi-channel audio-video file > VR audio-video player with virtual surround sound engine running on Android smartphone with 4K display slotted into a VR headset > multi-channel PCM stream > USB audio out >> portable USB DAC/amp >> headphones

multi-channel audio-video file > VR audio-video player running on Android smartphone with 4K display slotted into a VR headset > multi-channel PCM stream > USB audio out >> portable USB DAC/amp with virtual surround sound engine >> headphones


A current VR headset: Samsung Gear VR
http://www.cnet.com/products/samsung-gear-vr/

The Gear VR headset works in conjunction with a Samsung Galaxy Note 4 smartphone.





A current smartphone to be slotted into a VR headset: Samsung Galaxy Note 4 smartphone with 2560*1440 (i.e. QHD) Super AMOLED display
http://www.androidcentral.com/samsung-gear-vr-face

"Even with a fantastic Super AMOLED display at QHD resolution at your disposal, when you place it mere inches from your face, magnify it with lenses and split it in two to give the virtual reality effect, you quickly run out of pixels. Images were still grainy compared to viewing a phone or TV at a distance, of course, and that'll be a tad disappointing if you're expecting a higher resolution. That said, if you've used any lower-resolution virtual reality you're going to be in for a treat because you have that additional perspective."


A current VR music player: Oculus 360 Videos - Strangers with Patrick Watson
http://www.wired.com/2014/03/sxsw-li...4/#79191019861

"I experienced an immersive music video set that makes you feel like you’re sitting in the middle of a musician’s apartment as he performs. Every time I turn around, I’m actually looking at the man’s dog, who is sitting “behind” me. It seemed so real that at one point I actually reached for my smartphone to take a picture — until I realized I couldn’t. (Yet.)"




A current VR movie player: Oculus Cinema
http://www.roadtovr.com/samsung-gear...-2-hour-movie/

"A virtual movie theater where movie trailers and even self-loaded [2D / 3D] videos can be seen. What's amazing here is the theater itself: you can pick a giant cinema, a screening room, or even the surface of the Moon. The expansive theater, and its seats illuminated by the movie screen, feels so real that it seems like it could be a movie theater replacement in the near future...if the actual video resolution seen in that virtual theater ever ends up approaching the "retina quality" of existing phones, tablets and TVs."

"The most jaw dropping moment was when the movie started and I really did feel that the screen was meters away, and many more meters in actual size. My eyes were genuinely tricked into believing the images on the virtual screen were on a real screen, and I think it was partly due to the perfect audio sync. This enclosed fusion of audio and visual delivery kept the illusion at a high level for a long while."












A current DAC/amp with virtual surround sound engine: Smyth Realiser A8
http://www.cnet.com/news/smyth-reali...er-headphones/

"After spending some quality time listening through his Smyth Research Realiser A8, I can testify to its effectiveness. With the Realiser A8, room-filling sound was produced by headphones!
When I heard the Realiser A8 do surround for the first time, I whipped the headphones off in disbelief. Wow! The sound wasn't coming out of the surround speakers! The Realiser A8's spatial localization is 100-percent convincing. The system comes with a set of very-high-quality Stax SR-202 electrostatic headphones and a Stax headphone amplifier, but you can use any headphone with the Realiser A8."






Virtual surround sound engine to be implemented in a VR audio-video player software or in a USB DAC/headphone amp:
http://www.smyth-research.com/licensing.html

"SVS is the name of the technology used in the Smyth Realiser. All aspects of SVS are available for licensing."

There are other virtual surround sound technologies like Dolby Headphone, Silent Cinema, ....


USB multi-channel solution to be implemented in a USB DAC/amp with virtual surround sound engine:
http://www.xmos.com/products/referen...s/multichannel

"The USB Multi-Channel Audio U16 Platform is a complete development hardware and reference software solution for multi-channel USB audio applications."


Oculus Mobile SDK available for VR audio-video player developers:
http://techcrunch.com/2014/11/12/ocu...vr-developers/

"The SDK also contains the full source code for Oculus Cinema, Oculus 360 Photos and Oculus 360 Videos under an open software license, which represents the full suite of first-party apps available on the new mobile VR platform."


Android smartphone with 4K OLED display: Samsung Galaxy Note 5 (?)
http://www.phonearena.com/news/Samsu...Note-5_id62541

"Rejoice, 4K lovers, as that's the resolution you might be getting with the next edition of Samsung's Galaxy Note series. We got tipped that Samsung will start mass-producing a 5.9" Ultra HD Super AMOLED display with 700+ppi next August, which puts manufacturing plans just in the timeframe for the Note 5 release, if everything goes according to traditions."

Danba,
regarding post #321
Sony's native Walkman app does the same in my Xperia Z3, the downside is that I can't control the volume with the attached DAC/amp like my HRT microstreamer. If I want to listen to headphones I would have to include another amp after the HRT, so I use this set up instead in my car via the external audio input, and I can play my HR files in native form for the first time.
So I wonder if the Onkyo app would work the same way, since the HRT's volume control and Dragonfly's as well is software based. When I had my HRT connected to my laptop the media player's volume control was able to control the HRT just fine even when the Windows audio framework was bypassed. Maybe the new HRT microstreamer you posted about would needed in my case if I wanted to use headphones.......?

The USB Audio Player PRO music player and the currently free HibyMusic player have the volume control feature for USB DAC like HRT microStreamer or AudioQuest DragonFly.

"Hardware volume control for USB DAC added (without UI display, just press Volume+/- button while using USB DAC)"
