Ah well, QT on Windows has never worked for me. It is dire as a browser plugin, and I ended up uninstalling it completely. Unless it 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.

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
