===== Description =====
\\
The Dynamic Enhancement block provides variable bass enhancement as a function of input-signal level. Lower levels require more bass than higher levels. The filter dynamically adjusts the amount of bass enhancement depending on the volume of the input signal, by using a variable-Q filter.

A fixed enhancement is applied to input levels below the threshold while a dynamic gain is applied to input levels above the threshold.
