when switching to AIFF then as I guess the same restrictions apply?
Thanks

The best you will get is the same 4GB limit. But AIFF is in fact a
little more uncertain than WAVE as the formal spec itself is remarkably
confused, specifying signed integers for chunk sizes but unsigned
integers elsewhere. Probably the spec is just lazily written. The only
sane thing to do is to use unsigned, but sanity cannot always be relied
upon! So depending on your software it may or may not allow 4GB files
anyway. AIFF (and even AIFF-C) really is on the way out - it is
occasionally used for some sample files in Logic Pro, but CAF is used a
lot more now. With the move by Apple to Intel CPUs a big-endian file
format is in any case rather less attractive.
