d56920e206 aacenc: Correct spreading calculation for high spreading.
The 3GPP spec uses the following calculation for high spreading:

thr'_spr = max(thr_scaled, s_h(n) * thr_scaled(n-1))

where, n is defined as the current band, and s_h() is defined as "[...] the
distance of adjacent bands in Bark and a constant slope that is 15 dB/Bark
[...]". This is a little ambiguous as you would assume you want the Bark
width of the previous band for this calculation. However, this assumption
appears to be incorrect, and you really want the Bark width of the current
band. Coincidentally this is exactly what the spec calls for! =P

This noticeably improves Tom's Diner at low bitrates (I tested at 64kbps,
with mid/side disabled).

c8dcb9dee1 aacenc: Remove energy 'normalization' modification from the 3GPP psymodel
This greatly improves bitrate handling. You will now get within a few
kbps of your requested bitrate instead of 20-40kbps higher.

There is absolutely no analog to this line in the 3GPP spec, that I
can find.

4df5aebb81 aacenc: Fix threshold-in-quiet calculation in the 3GPP psymodel.
Removing the modification vastly improves quality (at a slight bitrate
cost) for some samples. castanets.wav is a good example. The closest
equivalent I see to the modification in the 3GPP spec is a similar
modification (over a specific frequency range) when TNS is used.

This also changes the threshold-in-quiet calculation to match the
3GPP spec.

eafadadaf5 aacenc: Fix the conditions under which 3GPP pre-echo control is run.
According to the 3GPP spec:
"Thus the pre-echo control is inactive for the first short window (but
not all short windows in a short frame) after a start block and for
all frames with a stop window sequence."

Currently, pre-echo control is only run when the current frame is not
a short frame, and the previous frame is not a short frame.

276df9d821 aacenc: Fix bug in LAME windowing where only one channel got initalized
I used the same loop counter for the inner and outer initalization loops.
This caused initalization to only run for the first channel. This in turn lead
to any channel other than the first using only short blocks.

62147469da acenc: LAME-inspired window decision
This performs quite a bit better than the current 3GPP-inspired window decision
on all the samples I have tested. On the castanets.wav sample it performs very
similar to iTunes window selection, and seems to perform better than Nero.
On fatboy.wav, it seems to perform at least as good as iTunes, if not better.
Nero performs horribly on this sample.
