In Reply to: RE: iTunes might be offering Hi-Rez soon? posted by Waxxy on April 10, 2014 at 15:18:14
No "i" product contains a DAC that is capable of natively playing a file with a resolution that is higher than 24/48. A few companies have signed a licensing agreement with Apple to allow for the extraction of raw data that can be sent to an external Dac for processing. But such an interface negates the portability of i products.
A high Rez capable i product will mean one has to purchase another i product if portable features are to be retained. Otherwise one will be locked into desktop only use of Apple encrypted high Rez files.

Onkyo HF Player App Offers Precision Equalizer, 192/24 Playback on iOS Devices
Press Release dated: 24 Oct 2013
* Free HF Player Includes 16,000-band FIR Equalizer with Memory Presets
* In-App Purchase Enables 192 kHz/24-bit DSD*, FLAC, WAV Playback on iOS
The DACs in the current generation of "i" devices are incapable of reproducing digital data with a resolution greater than 24/48. Anything higher will be downsampled.
Apple will have to release new players with hirez DACs before native hirez playback is possible.
So not only will we have to purchase additional copies of music we already own, we will have to purchase new devices to play back the new files.
Best,
Ross
How do you know this about the iDevice's internal CODEC chip? Do you have credible web links with actual specs? It is my understanding that the newer iDevices use an Apple spec'd Cirrus Logic CODEC but I have yet to see published specs. Thanks.
If 'native hi-res' is not available from the internal CODEC and lineout or headphone out, it is certainly available via USB using the USB camera connection kit to external DAC. Along with the Onkyo HF player, it will enable support for 24/192 PCM in various popular formats (FLAC, WAV, etc.) and DSD.
...for iTunes, hi res would be Lossless or AIFF - 16/44.1.
