Playing FLAC files up to 192 kHz through the FLAC Player.

Hi guys, can I ask if the Fostex hp-p1 be able to play the 24bit files as they are or would it down-sample them?

Has anyone that successfully loaded files higher than 24/48 onto Music Player on their iPad now notice a crackling noise when playing them through a USB DAC?  I have been experiencng it while playing FLAC files at 24/88 or higher via FLAC Player.  I am using a Fiio E17 with a powered USB hub.  I am working with Dan Leehr to try and fix this problem with FLAC Player, but I wanted to see if it was isolated to FLAC Player or if it pertained to all higher res files regardless of player.  I will try to load some AIFF or ALAC copies of my FLAC files via the method described above.  I am using Windows Vista and Foobar 2000 to do the conversion.  I'll chime in with my results.

BTW, this crackling noise all started to present itself after I updated to iOS 5.1.  Prior to the update, there was no crackling noise.

As yesterdays 'discovery' used a couple tracks from Explorations In Space And Time in 24/192 FLAC converted in Max to AIFF, I used a Reference Recording HRx disc this time (hint: results similar). And I can see why other are having problems. There is another solution, which was Benchmarks and I'll get to that at the end.

Placed WAV into iTunes and dragged to docked iPad: 'Was not copied as this file cannot be played on this iPad'

 

WAV converted to ALAC in iTunes (confirmed in Get Info to be 24/176.4, listed as 4386 kbps): 'Was not copied as this file cannot be played on this iPad'

 

WAV converted to AIFF in iTunes (all automatic settings - confirmed in Get Info to be shifted to 16/176.4, listed as 5644 kbps - no 24 bit settings to force): 'Was not copied as this file cannot be played on this iPad'

 

Converted ALAC from iTunes opened in Finder, directly dragged back to docked iPad in iTunes: 'Was not copied as this file cannot be played on this iPad'

 

WAV converted in Max 0.9.1 to AIFF (linear PCM - confirmed 24-bit with 8467 kbps tested both AIFF and AIF as extension) and dragged from Finder directly to docked iPad in iTunes: Success

 

iTunes ALAC converted in Max to AIFF (linear PCM - 24-bit with 8467 kbps) and dragged from Finder directly to docked iPad in iTunes: Success

 

Max AIFFs added to iTunes and then dragged to iPad: 'Was not copied as this file cannot be played on this iPad'

That's onboard though. Rereading the Benchmark piece they were all about streaming. Turning on Home Sharing opens up your iTunes library to your iPad and 24-bit files there, such as the ALAC iTunes produced files I was unable to load to the iPad. I can confirm streamed those files output correctly up to 24/94 (maybe more my V-Link is the bottleneck). 

Have similarly tested the Squeezepad (with in app streaming) and iPeng HD and unfortunately they seem to downsample everything to 16/44.1 for the iPad, unless I'm missing a setting somewhere on the server.  

Hi All,

I am wondering what is the current (pun intended) state-of-the-art for high-resolution audio files out of the iPad?

Is it this post above?    

Do I merely rip using the FLAC player I found today in iTunes?  

Or do I need to do the converting-drag-and-dropping?

Should I bother with the Matrix Audio DC for "only" 24/96 ?

There is a lot in this thread, and I am looking for what is still relevant as of today, 25 November 2012.  Thank you !
