Shorten's compression ratios are very good as lossless goes (I know; an early
incarnation of Ogg was a competitor to shorten. I got better ratios, shorten
was faster IIRC, but the difference on both fronts was very small). If Shorten
is still supported, don't bother looking for an old copy of Ogg (which I
*don't* support any longer).
Depending on the musical source, typical pop music taken directly from CD as
data would get between 1.2:1 and 2:1 depnding on the amount of noise content
(any cymbals? Kiss your ratios goodbye). Just so folks know what to expect.

(BTW, lossless compression is a very nifty problem that I want to get back into
once Vorbis is a bit better in hand. I know how to improve on the previous
generation, but I need to invent some math to do so. Any applied
mathemeticians on the list? :-)
