iPad with software version 5.0.1 plays up to 384 kHz audio files through the Zodiac DAC. Here's a short demo video.
Playing FLAC files up to 192 kHz through the FLAC Player.
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.
Okay, this was waaaay more complicated than I expected. Guess I got lucky yesterday. And unfortunately it doesn't give me confidence that the option will always be around, but results below.
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.
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.
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 !
