MainStage Space Designer density envelope
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 Level, Ramp Time, and End Level parameters using the techniques described in Edit Space Designer envelopes in MainStage.
Note: The density envelope is available only in Synthesized IR mode.
Density envelope parameters
Init Density field: Set the initial density (the average number of reflections in a given period of time) of the reverb. Low density levels result in audible reflection patterns and discreet echoes.
Ramp Time field: Adjust the time between the Initial and End Density levels.
End Density field: Set the density of the reverb tail. 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.
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.
