AIF Files (was Audio Converter and Endians problem)

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

My problem is that I currently don't have access to a Mac system. I am mostly lurking on this list until that situation changes, as I am determined it will soon. But it means I don't have the development system either, so can't read header files to find out stuff.

If this is truly an aspect of generic AIFF-C (i.e could conceviably crop up on a file being read on an Intel platform,) it needs to be formally documented in an external specification document, not just in Mac developer header files. Otherwise, I have to regard it as "undocumented". Just how public/portable is all that stuff? It is only used for reading CDs in Macs?

Try checking out the Carbon Sound.h header file, it has many of the constants for AIFF compression schemes (I presume the Quicktime headers have many of them too)

Failure is not an option. It is a privilege reserved for those who try.
