Description
This parameter sets the amount of time (in milliseconds) it takes the expander
to ramp down to the target gain once the input signal drops below the
expander threshold.
dp_exp_en Enable Expander
Description
This parameter enables (1) or disables (0) the expander function of the
dynamics processor. This parameter and dp_en must be enabled for the
expander to function.
