Parameter Description
Release Threshold This parameter controls the level in dB below the Attack Threshold at
which the Release phase of the ADSR will begin.
Attack Retrigger By default, when the value of this parameter is Disabled, the Reshaper's
ADSR engine will wait until at least the Release phase of a cycle before
restarting a new Attack phase.
By setting Attack Retrigger to Enabled, however, the Reshaper becomes
sensitive to new input signal transients during any phase of the ADSR
cycle. In addition, enabling this parameter will also cause the attack to
restart at the Release Level instead of whatever gain was being applied
when the new attack arrived.
Attack Curve This parameter allows the gain during the Attack phase to follow one of
3 curves: linear, logarithmic, or exponential. Because the ADSR
computes gain using linear coefficients, the exponential curve comes
the closest to being a "constant in dB" gain ramp. A linear curve
provides a somewhat more immediate turn-on, while the logarithmic
curve presents a very abrupt turn-on.
Release Curve This parameter selects gain curves exactly as for the Attack Curve
parameter, except that the selected curves apply to both the Decay and
Release phases of the ADSR.
