Lame mp3 at 128 kbit/s and FhG mp3 at 64 kbit/s are used as the high
and low anchors, respectively.

1. No codec at 64 kbit/s can claim to be as good as mp3 at 128
kbit/s.
2. High efficiency AAC (AAC with spectral band replication, similar
to mp3 with SBR, aka mp3pro) makes a good first showing, being the
first among equals (he-aac, mp3pro, and ogg vorbis).
3. WMA9, Real, and Quicktime AAC make poor showings. While better
than the hoary mp3 at 64 kbit/s, they are definitely worse than the
top three 64 kbit/s contenders.

The test introduces schnofler's java version of abc/hr, the blind
listening utility:
