The Dynamic Bass Boost block provides a boost that varies with input signal level. A lower level of signals requires and receives more bass than a higher level of signals. By using a variable Q filter this block dynamically adjusts the amount of boost required for an input signal.
The filter calculates its bass boost between the Threshold and minimum Gain settings. A fixed maximum bass is applied to inputs above the minimum gain and below the Threshold level.

LowPassFrequency | 250 Hz | 20 to 250 Hz | Frequencies below the LowPassFrequency settings are used by the detector to determine the boost amount |
HighThreshold | -5 dB | -45 to 10 dB | Higher Threshold of the detector.Any signal coming into the detector above the threshold level wil not influence the boost calculation. it recieves a fixed boost |
TimeConstant | 100 ms | 0 to 500ms | This controls the rms time constant for the detector. Changing the attack and release rates |
LowThreshold | -25 db | -100 to -20 dB | Lower Threshold of the detector.Any signal coming into the detector below the threshold level wil not influence the boost calculation. it recieves a fixed boost |
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 gain applied to the algorithm |
BassFrequency | 60 hz | 20 to 300 Hz | Cut off frequency for the boosting filter |
