Ah well, QT on Windows has never worked for me. It is dire as a

has been fixed recently, on both Windows and the Mac (when I had one
last year, running OS X) it doesn't render AIFF-C float files
properly, unless the header gives the wordsize as 16bits (!!!). I
discovered this trying to find out why AIFF-C floats files generated
in CSound were not being rendered properly. We naturally presumed that
for a 32bit floats file, the wordsize should be recorded as 32.
Basically, I avoid anything to do with QuickTime! Any applications
that rely on the QT libraries I have to assume are similarly > afflicted.
That was fixed with the latest release of QT. and it also should now do
the AIFC float files correctly (ie. as AIFC not AIFF files)

So even if QT exports a little-endian AIFF-C file, I cannot have 100%
confidence it is doing it "correctly". How would I know for sure,
without a written spec for the format to check it against, anyway? A
program, library, or even an API, is not an adequate specification for
a file format.

Try using QT on Windows - it will do the same things and you can
export I think to both the big and little endian flavours... and as
Mark said, a WAV file is remarkably similar to an AIF file...
This has been in use for a number of years.
And, just as little-endian data is considered a "compression" format,
so is Float32 - thus this should be contained within an AIFC file
