aoTuV implemented some of the GT tunnings, as far as I know.  And it's
supposed to be merged sooner or later with the official Vorbis
library/encoder.

Regardless, though, both versions (aoTuV and official) have an advanced command:

--advanced-encode-option impulse_noisetune=x

where x is equal to a number between 0 and -15.  The lower you go, the
more bitrate is allocated.  It's known to make history of pre-echo
issues.
