At the risk of saying something completely heretical on an Apple list:
if you just want to read/write soundfiles, you may have a happier time
using a free (well, LGPL) comprehensive independent library such as
libsndfile (very widely used, the de facto "industry standard", so can
be assumed to be as bug-free as any library can be). This will give you
complete flexibility, the most you will have to think about is the file
extension. .aifc covers you for everything. AIFF-C is no less robust
that AIFF (probably more so if anything), and setting aside the support
for compressed formats, hardly less plain. Apart from the name, the
difference is just in the COMM chunk, with maybe an extra dozen or so
bytes. With libsndfile, the most you would have to pay attention to is
the file extension.

What about few hundreds of computer generated or professionally recorded
files a day? It is still convenient in many situations to have plain
AIFF rather than "compressed which in fact happens not to be
compressed". After all they are still way easier to debug, hack and
extensively process. It's not my fault that some industry standards
STILL do require a format that plain and robust. All I want to know is
if one can create plain AIFF within CoreAudio at all?
How to make QuickTime stand off your way? What is the corrupted part at
the end of the files?
A magic cookie? Why is it needed if the file is not compressed?
Is there a ready-made routine to write an AIFF file - not the one which
ends-up in becoming a QuickTime AIFC track?
