The Distortion process
Notice how some of the values of the distortion
parameter produce more regular sounding noises
than others. This is because, despite the name, the
pattern of random pulses which comprise the
random waves is repetitive. The difference between
the various random waves is the time over which
the pattern repeats. If this time is short, the noises
produced appear repetitive and are useful for
engine noises, for example. The most random
noises are good for explosions and gun shots.
