Chapter 13 Space Designer convolution reverb 245
Edit Space Designer envelope parameters
You can edit the volume and lter envelopes of all impulse responses and the density envelope
of synthesized impulse responses. All envelopes can be adjusted both graphically in the main
display as well as numerically in the parameter bar.
Whereas some parameters are envelope-specic, all envelopes consist of the Attack Time and
Decay Time parameters. The combined total of the Attack Time and Decay Time parameters is
equal to the total length of the synthesized or sampled impulse response, unless the Decay time
is reduced. See Use impulse responses on page 240.
The large nodes are value indicators of the parameters shown in the parameter bar below the
main display—Init Level, Attack Time, Decay Time, and so on. If you edit any numerical value in
the parameter bar, the corresponding node moves in the main display.
When displaying envelopes, the main display oers the following zoom and navigation
parameters (not shown in EQ view).
Overview display
Envelope navigation parameters
•
Overview display: Indicates which portion of the impulse response le is currently visible in the
main display, helping you to orient yourself when zooming.
•
Zoom to Fit button: Click to display the entire impulse response waveform in the main display.
Any envelope length changes are automatically reected.
•
A and D buttons: Click to limit the Zoom to Fit function to the attack and decay portions of the
currently selected envelope shown in the main display. The A and D buttons are available only
when you are viewing the volume and lter envelopes.
Move an envelope node graphically in Space Designer
m Drag the node in one of the available directions.
Two arrows are shown when you move the pointer over any node in the main display, indicating
possible movements.
Change Space Designer’s envelope curve shape graphically
1 Drag the envelope curve in the main display.
2 Drag the small nodes attached to a line for ne adjustments to envelope curves. These nodes are
tied to the envelope curve itself, so you can view them as envelope handles.
Move the nodes vertically
or horizontally to change the
shape of the envelope curve.
