For those who are interested, I've run 3 EAQUAL tests on both the LAME and
OGG encoders: LAME with the --alt-standard preset (with and without
--nspsytune) and OGGENC (RC3) with -q 6 (my personal "sweet spot")
I am somewhat unsure though about the validity of these tests, since the
original and decoded files were not the same size (2 KB difference). The LAME
encoded files were also DEcoded by LAME (--decode), and the OGG encoded files
were decoded by the Winamp DiskWriter plugin. Same number of frames on all
files though (5001).

I am somewhat confused by the positive ODG values on two of the tests, since
I thought the ODG values only ran from -4 to 0 (-4 being heavily perceptible
differences, and 0 being none). Can someone explain this?
Furthermore, I'm having some problems figuring out what the other values
mean, even with the explanation in the EAQUAL readme.
