Space Designer density envelope in MainStage
The density envelope controls the density (the average number of reflections) of the synthesized impulse response over time. You can adjust the density envelope numerically in the parameter bar, and you can graphically edit the Init Density, Ramp Time, and End Density parameters using the techniques described in Edit Space Designer envelopes.
Note: The density envelope is available only in Synthesized IR mode.
Density envelope parameters
Init Density field and node: Set the initial reverb density (the average number of reflections in a given time period). Low values result in audible reflection patterns and discrete echoes. Drag the node vertically.
Ramp Time field: Adjust the time between the Initial and End Density values.
End Density field: Set the density of the reverb. An End Density value that’s too low can result in a grainy sounding reverb tail. The stereo spectrum may also be affected by lower values.
Ramp Time / End Density node: Drag the node horizontally to set the Ramp Time value. Drag vertically to set the End Density value.
Reflection Shape field: Determine the steepness (shape) of early reflection clusters as they bounce off the walls, ceiling, and furnishings of the virtual space.
Low values result in clusters with a sharp contour. High values result in an exponential slope and a smoother sound. Reflection Shape is useful when recreating rooms constructed of different materials. When used with suitable envelope, density, and early reflection settings, you can create rooms of almost any shape and material.
