To select vocal type, click on the Vocal Type
pop-up and then select the desired stylistic
character from the pop-up list.
Glottal Pulse Width
This control allows you to select the pulse
width of the modeled glottal waveform. If you
are at all familiar with analog synthesizers,
you can think of this as being vaguely similar
to the variable pulse width control on a square
wave oscillator (and if you’re not familiar with
analog synthesizers, don’t worry, just move
the slider and listen to what happens).
You will find that the most dramatic timbral
changes are usually found at the extreme ends
of this control’s range. If you’re looking for
realistic, stay in the middle 80% of the range.
IMPORTANT NOTE: Keep in mind
that this control interacts with the
Glottal Voice Type control above.
Each Voice Type sets a default Pulse Width that
is associated with it. So if you set this control
and then select a new Voice Type, the value of
this control will change to the new voice type’s
associated pulse width default. For that reason,
it is usually best to select the Glottal Voice Type
first and then make any desired adjustments to
the pulse width.
Command (Mac)/Control (PC)/Option (Pro
Tools) click the control to reset it to its default
value of 64.
GRAPHIC THROAT DISPLAY
Okay, here’s where the fun really starts.
The Graphic Throat Display allows detailed
tweaking of the model throat. For the purpose
of this control, the model throat is divided into
four sections defined by five boundary points.
For reference, these sections and boundary
points are illustrated on the head graphic to
the left of the Throat Shaping display. Point
(1) starts at the vocal chords and the sections
progress through the throat and the mouth out
to the lips, which are at point (5).
The Throat Shaping display itself consists of
two elements: the original throat plot and the
model throat plot. The original throat plot is
colored blue and is not user-changeable. It
represents the original length and width of the
four throat sections and serves as a reference
relative to which changes to the model throat
are made.
The model throat plot is colored red and
includes five control points that can be
grabbed and moved, eectively adjusting the
length and width of individual sections of the
throat.
Additionally, the background of the display is
divided into two sections by color. The lighter
grey central area represents the range of
adjustments that are consistent with typical
human anatomy. As long as all control points
and plot lines fall in this area, the results of
your model will be more or less “realistic.”
The darker grey area represents the range
of adjustments that exceed the dimensions
of typical human vocal tracts. When any
control point or plot line falls in this area, the
result may or may not sound like something
that you might recognize as a human voice.
The more points and/or plot lines fall in
this area, the more extreme the eect.
When you open a new instance of THROAT
Evo, the default state of the Throat Shaping
display is with the original and model throat
plots exactly superimposed, indicating no
dierence.
If you adjust the Throat Length and/or Throat
Width sliders, you will see the entire red model
plot move to reflect the changes. Length
