Oh, I only noticed your post after reposting my request...

Very good rendition at 56 kbs, but have you tried other compression formats:
-- AAC (56 to 16 kbs)
-- MP3+VBR (? to experiment on compressibility)
-- Ogg-Vorbis, for Wikipedia Media submission

When [and where] not to use the Bow Bells Indent: On PAL TVs with NICAM
Stereo...
-- TVNZ has the most excellent implementation of NICAM, with HDTV (DVB-T)
still being years away.
-- I wish Canada implemented NICAM Stereo, separate from the US BSTC
(totally sonically horrid)...

I found what you are looking for here :
