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.

TimeConstant | 100 ms | 0 to 500ms | This controls the RMS time constant for the detector. Changing the attack and release rates |
CompThreshold | -5 db | -24 to 20 dB | Threshold of the detector.Any signal coming into the detector below the threshold level will not influence the boost calculation. it receives a fixed enhancement. |
CompressorRatio | 3 | 1 to 15 | It is dynamic boost ratio.Controls the rate at which the bass boost changes from the low to the high threshold. |
BoostFrequency | 6 Hz | 0 to 16 Hz | Controls the maximum dynamic enhancement gain applied to the algorithm. |
BassFrequency | 60 hz | 20 to 300 Hz | Cut off frequency for the boosting filter. |
