The error would suggest that a fixed point 8.24 cannot be stored in a
wav file? Is this really the case? I have also tried setting the
fileTypeID to AudioFileCAFType but get the same error.


Yes, sadly (AFAIK), there is no WAVE format defined for 8.24 (or for any fixed-point format come to that). WAVE formats are available for integer PCM (e.g. 24bit) and 32/64bit floating-point. It is more surprising, giving how iOS-specific this format appears to be, from what you write, that CAF does not support it. If such files are for private use, you might just as well write raw values to a binary file suitably named.
