Dynamic Enhancement
Dynamic Enhancement Mono
Dynamic Enhancement Stereo
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.
Variants
- Dynamic Enhancement (Mono)
- Dynamic Enhancement (Stereo)

Configurable Parameters
| GUI Parameter Name | Default Value | Range | Function Description |
|---|---|---|---|
| —————————————- | ———————- | —————— | —————————————- |
| 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. |
