I extend this method little.
I think short block is used mainly to reduce the pre/post echo arround
big surge.
1.
A post echo is not noticible than pre echo because of temporal masking
effect. maybe we can use this effect.
2.
When the total energy of passege is small enough, we can't hear each
of the echo (because of ATH). So we don't need to use short block where
total energy of block is "enough" small.
I don't know where these are right or not, and they need some fine tuning
of parameters. But it may help quality improvement, I hope.
