Space Designer volume envelope controls in Final Cut Pro for Mac
The Space Designer effect’s volume envelope is used to set the reverb initial level and to control volume changes over time. You can edit all volume envelope parameters numerically, and you can also edit many of them graphically. See Edit Space Designer envelopes in Final Cut Pro for Mac.
To add the Space Designer effect to a clip and show the effect’s controls, see Add Logic effects to clips in Final Cut Pro for Mac.
Init (Initial) Level node and field: Set the initial volume level of the impulse response attack phase. Drag the node vertically. It is expressed as a percentage of the full-scale volume of the impulse response file. The attack phase is generally the loudest point of the impulse response. Set Init Level to 100% to ensure maximum volume for early reflections.
Attack node and field: Determine the time before the decay phase of the volume envelope begins. Drag the node horizontally.
Decay node and field: Set the length of the decay phase. Drag the node horizontally.
Note: The overall decay is determined by the global Length and Size parameter values. For example, a Length value of 100% and a Size value of 100% result in a decay that is the full length of the loaded impulse response.
Exp (Exponential) button: The decay curve of the volume envelope is shaped by an exponential algorithm, in order to generate the most natural-sounding reverb tail.
Lin (Linear) button: The decay curve of the volume envelope is shaped by a linear algorithm, and results in a less natural-sounding reverb tail.
End Level node and field: Set the end volume level, expressed as a percentage of the overall volume envelope. Drag the node vertically.
If End Level is set to 0%: You can fade out the reverb tail.
If End Level is set to 100%: You can’t fade out the tail, and the reverb stops abruptly if the end point falls within the tail. If the end time falls outside the reverb tail, End Level has no effect.
Bezier curve node: Drag to create or change convex, concave, or S-curve shapes for the associated envelope phase.
