It seems to me that we have to emphasise spectrum of that second
granule here before "return 0" in the case when preflag is set for the
first granule, and then return 1. I.e. to do the same as under
"if (over == 4 )" condition (see preemphasis() below).
Otherwise it will be decoded the wrong way - HF will be too loud.
Is it right?
