Values above 1.00 represent a widening of 
the throat while values below 1.00 represent 
a narrowing of the throat. The actual values 
represent the percentage change in the throat 
width. For example, a value of 1.20 represents 
a 20% increase in throat width, while a value of 
0.80 represents a 20% decrease in throat width.
NOTE: As with the Throat Length 
control above, if you are going 
for “realism,” limit yourself to 
modifications of about +/- 20%. For special 
effects, anything goes.
To adjust Throat Width, click on the knob and 
move the cursor up to turn the knob clockwise, 
or down to turn it counterclockwise. The numeric 
display will indicate the percentage  
of change.
Command (Mac)/Alt (PC) clicking on the knob will 
reset it to its default value of 1.00.
MUTATE SECTION
Having created your basic vocal characteristic 
with the Voice Design controls, the Mutate 
section let’s you turn that voice into a variety of, 
how shall we put it, alternative entities (i.e., weird 
creatures).
Mutation
The Mutation 
control allows you 
to select among 
24 different 
varieties of 
mutation, as well 
as being able to 
select “0,” which, not surprisingly, will result in no 
mutation effect.
Although the sound of each mutation setting 
depends to a great extent on the characteristics of 
the specific voice being processed, as a general 
rule, odd-numbered settings will typically result in 
more enharmonic overtones being added to the 
voice (i.e., weird growly or grunginess) than even-
numbered settings. When first experimenting, try 
starting with “8” and then work out from there.
Beyond that, there are really no rules for 
predicting how a particular setting will affect a 
particular voice. Trial and error is the method of 
the day.
varying the length of the voice’s model vocal tract. 
It can be used in combination with the Shift Pitch 
control to modify gender and/or vocal quality.
Values above 1.00 represent a lengthening of 
the throat while values below 1.00 represent 
a shortening of the throat. The actual values 
represent the percentage change in the throat 
length. For example, a value of 1.20 represents 
a 20% increase in throat length, while a value of 
0.80 represents a 20% decrease in throat length.
In addition to simply changing vocal timbre, 
increasing throat length is useful when the original 
input is female and you are shifting it down and 
want it to sound male. Conversely, decreasing 
throat length is useful when the original input is 
male and you want to shift it up to sound female 
or childlike.
NOTE: While this control gives you 
the ability to radically change the 
throat length, keep in mind that 
the variation in the length of human vocal 
tracts is rarely more than about 20% in either 
direction. If you are looking for a “realistic” 
vocal characteristic, start with modest settings 
of this control. More extreme settings can 
produce dramatic results, but probably not 
what anyone would call “realistic.”
To adjust Throat Length, click on the knob and 
move the cursor up to turn the knob clockwise, 
or down to turn it counterclockwise. The numeric 
display will indicate the percentage of change.
Command (Mac)/Alt (PC) clicking on the knob will 
reset it to its default value of 1.00.
Throat Width 
As you might imagine, this control is similar the 
the Throat Length control described above, but 
instead modifies the width of the modeled throat.
