Hi everybody,
 as you know the cirrus/wolfson DACs in our mobile phones could manage 24bit/96khz flows as well.
Unluckily it seems that the iOS is going to limit this feature handling a unique resolution/freq combination to feed the DAC.
 
Here my points:
- is it true? (ie.: if I put in my iPhone 24/48 files, iOS is going to down-sample it to 16/44.1 before sending the data flow to the cirrus dac)
- can anyone confirm that the "right combination" for the iphone 4s is 16/44.1?
 
If everything is confirmed, it would makes no sense to have 24/48 or 16/48 in our iphones... it could be even worse (due to the realtime down-sampling applied by the iOS). 
 
Thanks in advance for any feedback and sorry for my poor english.
 
ps.: of course using the 3rd party players (ie.: golden ear) does not fix the situation.

ehehe no answer... is it for my english?

is the Iphone4 meant to be able to play 24bit files?

iphones can actually play files 24bit/48khz (checked many times on my iphone 4s and 5).
 
my fear is that *probably* the iOS applies a real-time down sampling before pass these data-flows to the cirrus DAC (for several reasons mainly linked to energy saving and standardization).
 
so my point is: which exactly is the resolution/freq that arrives to the iphone DAC?
 
cheers

anybody could give me any insight about this topic?
