Thanks for the debate folks. What I'm gathering is that if I know what I'm doing, it's possible to use Objective-C safely for audio code, but if I only halfway (or less) know what I'm doing, it may be safer and simpler to just keep all real-time audio in C++ land.

Since the original post was about whether or not Objective-c is the 'wrong tool for the job', I was simply trying to illustrate that a complex audio project may have more than one 'job', and while objective-c should be avoided in render intensive 'jobs' of the audio, there are higher level areas of a project where it can co-exist quite usefully.

That kind of ignores the point of everything else I wrote, and is splitting hairs on wording. The word 'overhead' was meant to refer to any and all performance issues related to using objective-c in a render callback.

else. its that the objective C runtime can block.
