Replying to [comment:203 klaussfreire]:
> However, it seems the tendency to spend lots of bits on speech stems
from psy itself, not anything else. It seems to estimate speech has a lot
of perceptual entropy. It may be true, but there is some inefficiency
that's hard to fix without deviating from the standards.
Allocating less bits on short frame may help. It should increase the
quality, although a strong tonality estimator is ideal.
