Chapter 13 Space Designer convolution reverb 247
Space Designer density envelope
The density envelope allows you to control the density of the synthesized impulse response
over time. You can adjust the density envelope numerically in the parameter bar, and you can
edit the Init Level, Ramp Time, and End Level parameters using the techniques described in Edit
Space Designer envelope parameters on page 245.
Note: The density envelope is available only in Synthesized IR mode.
Density envelope parameters
•
Init Level eld: Sets the initial density (the average number of reections in a given period of
time) of the reverb. Lowering the density levels results in audible reections patterns and
discreet echoes.
•
Ramp Time eld: Adjusts the time between the Initial and End Density levels.
•
End Level eld: Sets the density of the reverb tail. If you select an End Level value that is too
low, the reverb tail sounds grainy. The stereo spectrum might also be aected by lower values.
•
Reection Shape slider: Determines the steepness (shape) of early reection clusters as they
bounce o the walls, ceiling, and furnishings of the virtual space. Small values result in clusters
with a sharp contour, and large values result in an exponential slope and a smoother sound.
This is handy when recreating rooms constructed of dierent materials. Reection Shape, in
conjunction with suitable settings for the envelopes, density, and early reection, will assist
you in creating rooms of almost any shape and material.
