iPad (or iPad 2) and 24-bit files - Page 3

post #31 of 69

Hey Now,

 

I just tried loading some AIFF HDTracks Hi-Rez 24bit/96Khz and 88.2Khz files onto to my 1st gen iPad. They loaded fine using the previously mentioned procedure by blessingx. I then hooked up my CCK > USB A-B > HA NG USB-COAX converter > Coax RCA cable > an old Zhaolu DAC > Amphora > AH-D2000 and it sounded great. I cannot confirm if the hi-rez files are actually being processed as 24bit/96-88.2, but I don't think the HA NG or Zhaolu down sample. 

 

I was using an iStreamer for the iPad at work, but I couldn't play the hi-rez files. It appears on the surface that the iPad is passing the hi-rez files to the DAC (I hope it is anyway). I just might take all this into work and use it as my office set up. Is there anyway for me to check if I am actually playing the hi-rez through my chain? Thanks in advance for any thoughts on this.

The specs on HA INFO NG have it max out at 16/48. I have one (helped out often in past with the iPad), so decided to test quickly using FLAC Player (24-bit music still in FLAC, though from earlier tests iPad app should respond similarly with AIFF Finder loaded).
 
Blond on Blond SACD "laserdrop" 24/96 + iPad 1 + camera kit + powered hub (not necessary with HA, but for consistency) + HA INFO NG + Lavry DA10 = LED reads 48mHz
 
Blond on Blond SACD "laserdrop" 24/96 + iPad 1 + camera kit + powered hub + Music Fidelity V-Link + Lavry DA10 = LED reads 96mHz
 
Repeated with same tracks in Decibel on MacBook + HA/V-Link, etc. Same results.

Hey Now blessingx,

Thanks for the information. Back to the drawing board. 8^(

surely if you cant hear the HDifference to be sure its working, then its a waste of time and money chasing the numbers?

 

naturally the interface has to be capable of 24/96 to pass 24/96 to the dac, to do that with the cck it needs to be able to do this natively ie. no driver needed

Hey Now,

 

YES, absolutely it's a waste of MY time and MY money! I waste my time and spend my money on frivolous things like left handed monkey wrenches and square egg presses tongue.gif

Blessing, have you tried to see if the stock LOD-USB cable will transmit hi-res to an external DAC, using the same setup but just subbing out the Camera Connection Kit? I'm not sure what about the kit would allow it to transport hi-res where a stock cable cannot.

ermm, hey now back at you, no need to get sarcastic, blow your money how you like, we all do, it just seems odd to me to chase the numbers when you have already proven to yourself you cant hear the difference....but hey be my guest

well yes the difference being everything thats inside the cck (otherwise why was it made in the first place?), ie. an authorization circuit that tells the ipad its OK to put out digital sound at all, hires or not. there wouldnt have been such a big deal made about the cck, or the CLAS in the first place if you could just use the standard lod usb pinout/cable, we as a community along with any noob that didnt know any better tried that many times and with many devices before admitting defeat. 

 

the cck was built to enable connection to cameras, some of those cameras have audio recording, plus they adhere to the usb 1.1 audio standard, it just happens as a byproduct because its part of the spec, we get the usb audio codec. Possibly unwittingly apple allowed a back door to digital audio; probably much to the dismay of companies that were making specialized digital ipod docks and car audio systems

not back to the drawing board, not at all, if the device works with ipad this way and if its codec allows 24/96 from its usb receiver, it should get hirez audio from ipad, simple as that. not all usb 1.1 codec dacs will take 24/96 from a computer either; they have to be capable of it. it seemsto be mostly dacs that are usb 2 audio compatible, but are backwards compatible with usb 1.1. if it requires a custom driver to do 24/96 it wont work

Thanks for the explanation, qusp.  I just wanted to understand what the CKK has that a stock cable doesn't.

 

So the DAC that I want to use with the iPad, the CLAS, requires a standard A input.  But it seems the CKK also uses an A plug?  What kind of cable do I need?

post #41 of 69

no problem man, sorry for the slight edge on the tone in your part of the reply, didnt mean it to spill over. unfortunately it wont work with clas, you can connect the clas directly, but afaik you wont get 24/96. CLAS is not a standard usb dac, you cant use it with a computer for example, it has to be an ipod/ipad. it has a custom receiver and DSP to reclock the audio data and control the transfer from ipod, the CLAS acts as the usb host.

So, are you guys all playing through Music app or other apps?  Anyone tried with DACPort/LX?

post #43 of 69

Not to grave dig or anything but I just converted a 24/96 flac into 24/96 aiff, loaded it onto my iPad 2, and it plays fine like a regular file through the music app. Sorry if this was mentioned elsewhere previously.

hey Guys..

 

glad i found this thread, because i did a month worth of

research to figure out how to play hi res files..

 

as far as the ipad goes..

 

doesn't matter how you configure it, if you are relying

on the ipad hardware to produce the sound, it's only

going to max out at 16/48..that's all the current hardware

is capable of..period

 

any files mixed above 16/48 that you manage to play

on an ipad simply get sampled down to 16/48, so you

aren't listening to hi res files.

 

so if you're like me and have downloaded some music

from www.hdtracks.com and want to hear what they

actually sound like..there is currently only 1 portable

solution that will play files up to 24/192

 

yes i said 24/192!

 

here it is=> http://www.colorfly.eu/

 

this solution can be used in your car as well as your home

and also a good pair of headphones..

 

i currently have it setup in my 2010 Range Rover Sport

and it sounds phenomenal!

 

i've installed a 10k audio system and i wanted to get the

most out of it, so i knew hi res files of 24/96 and 24/192

was the only way to go..

 

and if anyone tells you that hi res doesn't sound better..

 

IS FULL OF CRAP!

 

the sound is like day and night..literally

 

i will say that if you're going to play these types of files

then you need a sound system capable of reproducing

these sounds at the same quality..

 

so using your factory speakers in your car or using your

$300 surround sound tv package in your home isn't

going to cut it!

 

Colorfly comes with a detailed diagram and schematics

for hooking up sound for your home..

 

I personally just replaced my iPod with the Colorfly in

my vehicle..

 

of course i had to run optical cable, since USB does not

support 24 bit sound, at least not that i've seen.

 

but the colorfly has optical connections on it, so you'll

be forced to use them anyway..

 

the cost is high for a portable device, but it's well worth it

and if you're thinking about..just get it!

 

hope this helps,

 

-Bobby

 

 

...

See post #32, above.  It appears that digital output via the Camera Connector *will* output 96k, at least.
