[vorbis] RC2 artifacts

[k.m.krebs]

  Hello -- I desperately want to start using Ogg compression on music I
release on the internet, but I am encountering a fair amount of artifacts.
I noticed some in beta4 and was hoping they would disappear with RC1.
However, I've been playing with RC2 and I've still been banging my head into
a number of problems.  A majority of the music I make has long drones with a
fair amount of spectral content, and I often find these play havok with the
encoder.

  Here is a recent example I ran into.

original file (monkey's audio & lpac compression).

rc2 ogg files:

http://www.notype.com/users/833-45/ogg/fadein_128.ogg
http://www.notype.com/users/833-45/ogg/fadein_256.ogg

  no need for golden ears to hear to high frequency chirpy-bubbles in both
the 64 & 128 kbps versions.  The 256 version seems to avoid the problem, at
least to my ears.
