You mean the virtually transparent to the unskilled / casual listener
mode? I consider myself to have better than average ears, yet I really
have to listen carefully back and forth to hear the difference between
-q0 and original. -q0 Vorbis seems a little duller on the track I just
tried, but it's barely noticable, and for those who consider WMA at
48k "near-CD quality", I doubt most people would really care.

Tune that a little more, and you have one heckuvan audio codec. But we
all knew that already.

Monty rocks...

PS -- I'm worknig on oggtool, that big all-in-one Ogg file manipulator
tool (which could very well turn out working for many other formats
too, as I'm writing it very flexibly). Assuming it gets accepted as
the main Ogg tool (I'm thinking everything but encoding and playback,
but even those wouldn't be too hard to add) (and it just begs for a
nice GUI frontend), I'm depreciating oggchain before it even starts
working. There was some code a while back for a tool just called
"ogg", before I threw the whole thing out the window by doing those
crummy first attempts at real coding called vorbize and ogg123
(fortunately the first is gone and the latter heavily rewritten since
then, by Stan and myself). I hope to remedy my mistakes by re-writing
'ogg' (I might even decide to call it that, especially if it does
encoding), but much better. I've even included into the framework
exactly where the future peeler could go. If anyone's interested in my
preliminary code, which is mostly framework (needs a lot of fleshing
out), I'll put it up on CVS, but I don't think it's good enough for
that yet.

Sorry about the super-long "paragraph".
