When properly used, Objective-C programs are no more likely to be preempted than any other kind of program. Message dispatch generally has constant time and is only 2.5 times the cost of a C function call. There aren't many function calls or messages sent in audio processing anyway. Signal processing routines tend to be long loops. Objective-C _IS_ C which means it is likely usable in any situation where C is usable.
I am simply relaying the wisdom I received from the CoreAudio folks
over on coreaudio-api. Frequently people ask about using ObjC in their
render callbacks, and the engineers are quick to put the kibosh on
that idea.
