thinking a little more, given that i'm recording an arbitrarily long amount of audio, preallocating a buffer will not be possible, right? Is that where a circular buffer comes in? would I use the much used CARingBuffer? If so, could I get some intuition about the timestamps. I've followed chapter 8 of Chris Adamson's Learning Core Audio book and I sort of have a sense for using a RingBuffer but i'm not entirely clear on the concept of the timestamps you pass into it.

So I've actually read that a few days ago. i guess because the function was a core audio i didn't make the connection that it was i/o accessing. but right, i do recall that i/o restriction in the callback. What do you think was happening? it was only writing a a fraction of the total frame bytes before the callback returned? how do you account for the fact that the resultant wav file was long and shorter based on how long i ran the program?
anyway, now that I know this won't work, what is the right approach? Do I need to fill up a buffer in RAM and than start to offload those bytes into the audiofile back on a non-realtime thread?
