I don't know about PCs, but there are some differences for Macs. I've
been wanting to listen to those great RA files that people have on their
web sites but can't because I have a 68040 processor in my PowerBook at
home and my Quadra at work. RA 3.0 app and 28.8 files require a PowerPC,
although the company says I can listen to 14.4 files. I think most people
would be putting up 28.8 files, though. I don't think I have any problem
playing aiff files.
