Look what I found under the Xmas tree!
...auled psycha! Well, actually, the only big change
is that it does all of its computations in the dB domain, and does
some things just a little bit different, to improve performance.
Changed the ATH_Bark_dB array. This removes some very annoying
artifacts when encoding low-frequency, tonal sounds.
MDCT_COOR: this should reduce the blocking artifacts the MDCT
creates. This #define is tunable; smaller is less correction.
The algorithm is only exact for sine windows, but is ok for the
Vorbis window as well, as long as the flr[] is reasonably smooth
(in the high freq region). This should help low bitrates...
