Enveloper controls in Final Cut Pro for Mac
Enveloper offers the following controls.
To add the Enveloper effect to a clip and show the effect’s controls, see Add Logic effects to clips in Final Cut Pro for Mac.

- Threshold slider and field: Sets the threshold level. Signals that exceed the threshold have their attack and release phase levels altered. 
- (Attack) Gain slider and field: Boosts or attenuates the attack phase of the signal. When the Gain slider is set to the center position—0%—the signal is unaffected. 
- Lookahead slider and field: Sets the pre-read analysis time for the incoming signal. This enables Enveloper to know in advance what signals are coming, enabling accurate and fast processing. 
- (Attack) Time knob and field: Determines the amount of time it takes for the signal to increase from the threshold level to the maximum Gain level. 
- Display: Shows the attack and release curves applied to the signal. 
- (Release) Time knob and field: Determines the amount of time it takes for the signal to fall from the maximum gain level to the threshold level. 
- (Release) Gain slider and field: Boosts or attenuates the release phase of the signal. When the Gain slider is set to the center position—0%—the signal is unaffected. 
- Out Level slider and field: Sets the level of the output signal.
