5 - Effects Core Effects Descriptions Parameter Attack Lookahead/ Delay Release Threshold Attack Retrigger Attack Curve Release Curve Description This parameter is adjustable in milliseconds to allow the Reshaper to either "look ahead" and advance (negative values) or "delay" (positive values) the response of the envelope detector relative to the dynamics of the input signal. For example, negative lookahead values can cause the envelope detector to start the ADSR's Attack phase before the actual attack of the signal so as not to miss any audible transients. Likewise, positive delay values can be used to start the Attack "late", so that signal transients are intentionally missed by the Attack. This parameter controls the level in dB below the Attack Threshold at which the Release phase of the ADSR will begin. 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. 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. 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. 86 Creative Professional
