iphone 4s bit perfection

post #1 of 5
Thread Starter 

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.

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
