VOCAL
RANGE
Use this
control to
select the
range of the
track you will be processing. Choices include
soprano voice, alto/tenor voice, baritone/bass
voice and instrument (a general setting for
anything that isn’t actually a vocal).
Matching the appropriate algorithm to the input
results in faster and more accurate pitch detection
and more accurate pitch shifting and modeling.
To select vocal range, click on the Vocal Range
pop-up and then select the desired range from
the pop-up list.
NOTE: Choosing the wrong Vocal
Range (or just forgetting to set it
at all) can result in compromised
performance. Pay attention.
VOICE DESIGN SECTION
The following three controls allow you to create
the basic vocal characteristics of your voice.
Shift Pitch
As its name
suggests, this
control is used
to shift the pitch
of the input
voice either up
or down.
MUTATOR
Evo’s pitch
shifting automatically includes formant correction
(i.e., it preserves the resonant characteristics
of the original voice), however you can further
modify the vocal characteristics using the Throat
Length and Throat Width controls described
below.
The range of the control is four octaves — two
octaves up and two octaves down. The control is
calibrated in 48 discrete steps of a semitone each.
Since an octave is equal to twelve semitones,
the values of this control are equivalent to the
following musical intervals:
1 = minor 2nd
2 = major 2nd
3 = minor 3rd
4 = major 3rd
5 = perfect 4th
6 = aug 4th/dim 5th
7 = perfect 5th
8 = aug 5th/min 6th
9 = major 6th
10 = minor 7th
11 = major 7th
12 = octave
13 = minor 9th
14 = major 9th
15 = minor 10th
16 = major 10th
17 = perfect 11th
18 = aug 11th
19 = perfect 12th
20 = minor 13th
21 = major 13th
22 = minor 14th (rarely used)
23 = major 14th (rarely used)
24 = 2 octaves
To adjust pitch shift, 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 number of semitones shifted.
Command (Mac)/Alt (PC) clicking on the knob will
reset it to its default value of 0.
Throat Length
This control uses the vocal tract modeling
technology from THROAT to modify the vocal
characteristics of the input voice by actually
