FFT Size Sets the FFT (Fast Fourier Transform) size, or the size of the pieces of data that the effect processes. In
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.
Pitch Reference graph Displays the pitch in single half-step increments along the vertical ruler (y-axis) and time
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 Show the amount of correction you need at any given point in a waveform.
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.
Pitch Edit graph Displays the pitch in half-step pitch increments along the y-axis and time (in the same format as the
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 Lets you control how pitch correction is applied. Click on the line to create a
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).
• Readout below the graph Shows the position of a control point as you drag it.
Vertical scroll bar Lets you scroll to a different portion of the Pitch Reference graph. Zoom in or out by dragging the
edge of the slider.
Horizontal scroll bar Lets you scroll to a different time range of the waveform in both graphs. Zoom in or out by
dragging the edge of the slider.
You can also zoom by right-clicking the sliders and choosing Zoom Out or Zoom Out Full.
Zoom buttons Zoom in and out of the Pitch Edit graph. The maximum amount you can zoom in is plus or minus
one-half step. The maximum you can zoom out is plus or minus 200 cents. (The waveform isn’t affected by vertical
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.)
