1. Frequency / (Pitch) control
The threshold option sounds like it causes
nothing but disturbance.
All the other options below the ratio option are used to modify the effects of the
adjusted pitch/frequency and other effects that have already been used.

2. The amount setting, determines how much the effect
takes place, the higher the amount the more the effect
will be used through the audio.
The seed setting makes the audio sound more like an echo
and also makes it sound robotic.
The De-click setting adjusts the echo
effects.
The step envelope options adjusts
how many steps of audio are past
after every few seconds, the more
steps, the more audio is being
missed out.
The master filter options all deal
with the frequency, volume and
quality of the audio sequence.
The master output edits how much
the mix option applies to the audio,
and the other (volume) option jus
adjust how much louder or quieter
the mixed audio is.
Overdrive options just boost the
mixing settings
All of the options below only take effect, when a certain
method is applied to the audio.
