If I remember coding theory correctly, it isn't possible to data-compress a
totally random string of numbers, so I'd have to assume that the size of an
FLAC-compressed file depends on the predictability of the content of the
original. Has anyone tried FLAC? What sort of compression ratios (in
filesize) do you get? How different are the results between, say,
non-repetitive sonic artworks and sample-based pop?

I think you're right, although music corps may try to keep the hi-res audio
'for sale' (and copy-protected) and give away the low-res stuff.

best,
Ian
