This function should analyse the signal and decide how critical the
coding error will be perceptually. The following factors should be
taken into account:
-Attacks (positive energy derivative) should be coded with more bits
-Stationary voiced segments should receive more bits
-Segments with (very) low absolute energy should receive less bits (maybe
only shaped noise?)
-DTX for near-zero energy?
-Stationary fricative segments should have less bits
-Temporal masking: when energy slope is decreasing, decrease the bit-rate
-Decrease bit-rate for males (low pitch)?
-(wideband only) less bits in the high-band when signal is very
non-stationary (harder to notice high-frequency noise)???
