Chapter 13 Space Designer convolution reverb 246
Space Designer volume envelope
The volume envelope is used to set the reverb’s initial level and adjust how the volume will
change over time. You can edit all volume envelope parameters numerically, and you can also
edit many of them graphically (see Edit Space Designer envelope parameters on page 245).

Volume envelope parameters
•
Init Level eld: Sets the initial volume level of the impulse response attack phase. It is
expressed as a percentage of the full-scale volume of the impulse response le. The attack
phase is generally the loudest point of the impulse response. Set Init Level to 100% to ensure
maximum volume for the early reections.
•
Attack Time eld: Determines the time before the decay phase of the volume envelope begins.
•
Decay Time eld: Sets the length of the decay phase.
•
Volume decay mode buttons: Set the volume decay curve type.
•
Exp: The output of the volume envelope is shaped by an exponential algorithm, to generate
the most natural-sounding reverb tail.
•
Lin: The volume decay will be more linear, and less natural sounding.
•
End Level eld: Sets the end volume level. It is expressed as a percentage of the overall volume
envelope.
•
If set to 0%, you can fade out the tail.
•
If 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 eect.)
