FFT Size
general, use smaller values for correcting higher frequencies. For voices, a setting of 2048 or 4096 sounds most
natural, and a setting of 1024 creates robotic effects.
Displays the pitch in single half-step increments along the vertical ruler (y-axis) and time
Pitch Reference graph
along the horizontal ruler (x-axis), so that you can see the exact transitions of the pitch in all parts of the source audio.
Pitch Profile and Pitch Correction lines
The red Pitch Profile line is not editable, and the green Pitch Correction line appears as you modify the edit envelope
in the Pitch Edit graph.
Displays the pitch in half-step pitch increments along the y-axis and time (in the same format as the
Pitch Edit graph
timeline along the bottom of the display window) along the x-axis. If the source is a stereo file, the graph shows the
channel you specified as the Reference Channel.
The Pitch Edit graph has two main components:
•
Adjustable blue envelope line
control point, which you can drag to set the correction for the audio material at that point in the time scale. For more
precision, right-click a control point to display the Edit Point dialog box, where you can enter values for Time Index
(x-axis) and Pitch (y-axis).

zooming, so it always retains the same vertical size.)
Pitch Shifter effect
The Time And Pitch > Pitch Shifter effect changes musical pitch. Unlike the other pitch manipulation effects,
however, Pitch Shifter is VST-based, so you can combine it with other effects in the Mastering Rack or Effects Rack.
In Multitrack View, you can also vary pitch over time by using automation lanes. (See "Automating track settings" on
page 204.)
