Volume Envelope Parameters
The volume envelope lets you set the reverb’s initial level and adjust how the volume
will change over time. You can edit all of the volume envelope parameters numerically,
and many of them can also be edited graphically using the techniques discussed in
“Setting Envelope Parameters” on page 182.
The volume envelope includes the following parameters:
 Init Level: Sets the initial volume level of the impulse response attack. 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 the early reflections.
 Attack Time: Determines the length of time before the decay phase of the volume
envelope begins.
 Decay Time: Sets the length of the decay phase.
 Volume decay mode buttons: Click to choose the volume decay curve.
 Exp: The output of the volume envelope is shaped by an exponential algorithm, in
order to generate the most natural sounding reverb tail.
 Lin: The volume decay will be more linear (and less natural sounding).
 End Level: Sets the end volume level. It is expressed as a percentage of the overall
volume envelope. If you set this parameter to 0%, the reverb tail cuts off abruptly,
which is great for gated reverb effects.
