To do sample rate conversions use the AudioConverter
There's actually examples of doing just this
/Examples/CoreAudio/Java/SDK/Output
I've run conversions from as low a 4K up to 192K through our converters and
not seen anything like the problems that someone else was reporting - which
I would guess is a problem in configuring the stream descriptions to
accurately describe to the converter what your source and destination
formats are.
For an example of that see CAServices/DefaultOutput (or some such) that has
some tweakable parameters to do a range of channels, sample rates, ints or
floats for source - you can stress test the converters this way for yourself
