I need to obtain audio byte stream from iPhone/iPad microphone and process it very quickly (early I did this using C language). Is it possible to do this using Unity as main developing platform?
As I understood, I should buy Unity iPhone Pro and use Unity plugin support (like in UnityMidi plugin example)?
You have to do this in C/C++/Obj-C and you don’t need Unity Pro. Unity 3 gives plugin access for free.
right, none the less, don’t forget that you can neither access nor interact with unity’s own audiosession
