Shape and Spread

The Shape parameter is closely tied to the Spread parameter. Shape controls how energy is

injected into the reverberator. A low value means that sound enters the reverb at the beginning

of the spread window. A high value means that most sound moves into the reverb at the end

of the spread window. A value somewhere in the middle means that sound enters the reverb

evenly across the spread window.

Tip: Shape will not have this effect if spread is at its minimum value. But even then, it can make

a difference. In this case, it affects reverb timbre and density. Higher values of shape may be

both darker and denser, although the effect is subtle.

The Spread parameter is closely tied to the Shape parameter. Spread is a window of time during

which a signal is injected into the reverb. Shape controls just how the signal is injected during

this window. Together, the two parameters create an envelope for the early portion of the

reverb, as shown in this illustration:

Shape = 32, Spread = 20%

Shape = Anything, Spread = 0%

Shape = 64, Spread = 75%
