The document describes using ReaDelay to increase the speed of an effect so that each replay was faster than the last. It also describes using Shifter to dramatically change an effect from the sound of a door shutting to the sound of a laser charging up.

1. Using ReaDelay I increased the
speed of the effect. Every time it
replayed it got faster and faster.
Using Shifter I change my
effect dramatically from the
sound of door swinging shut to
the sound of a laser charging
up.
