Please note that the Density Envelope is only available when in the Synthesized IR
mode.
Init Level
This parameter controls the density (the average number of reflections in a given
period of time) of the diffuse reverb. Both the Initial and End Density (Init and End Level)
can be controlled over time through use of the Density Envelope. Lowering the density
levels will result in audible reflections patterns and discreet echoes.
Adjusting this up or down can be done graphically in the Envelope window, or by click-
holding and dragging the mouse cursor up/down on the numerical entry.
Ramp Time
This parameter adjusts the length of time elapsed between the Initial and End Density
levels. Adjusting this up or down can be done graphically in the Envelope window, or
by click-holding and dragging the mouse cursor up/down on the numerical entry.
End Level
As above, but controls the reverb tail. If you select an End Level (End Density) value that
is too low, the reverb tail will sound grainy. You may also find that the stereo spectrum
is affected by lower values. Adjusting this up or down can be done graphically in the
Envelope window, or by click-holding and dragging the mouse cursor up/down on the
numerical entry.
Reflection Shape
The range from 0 to 100 determines the steepness (shape) of the early reflection
clusters as they bounce off the walls, ceiling, and furnishings of a virtual space. A value
of 0 results in clusters with a sharp contour and a value of 100 results in an exponential
slope, and a smoother sound.
