Adobe AUDITION 3 User Manual page 173

When specifying Rotation and Range settings, keep the following in mind:
• If you rotate the stereo field 180˚, both the left and right channels are 180˚ out of phase, inverting the entire
waveform.
• At 90˚ right, only the right channel is inverted; at 90˚ left, only the left channel is inverted.
• A rotation of 45˚ produces results identical to the Pan/Expand effect, panning centered audio to the left or right,
while panning surrounding audio in the opposite direction.
Stereo Field Rotate process effect (Edit View only)
The Stereo Imagery > Stereo Field Rotate process rotates the left and right channels, changing where instruments
and other sources appear to be located. By manipulating the Rotation graph, you can rotate sources over time.

Stereo Field Rotate process options
Represents the rotation of the stereo field over time. Use the graph to position the stereo field
Rotation graph
anywhere from hard left (the top of the graph) to hard right (the bottom) at any point in time. The x-axis (horizontal
ruler) of the graph shows the waveform's timeline, while the y-axis (vertical ruler) displays the number of degrees off
center for the left and right channels.
Reverses the graph so that an upward line spins the stereo field clockwise instead of
Invert Left/Right
counter-clockwise.
With the Phase Analysis window (Window > Phase Analysis), you can watch the stereo field rotate. For example, if
you create a graph that rotates audio to the right, the phase rotates clockwise. But if you also select Invert Left/Right,
the phase rotates counter-clockwise.
Sets the range of the y-axis from 45˚ to 360˚.

Note: If you rotate the stereo field 180˚, both the left and right channels are 180˚ out of phase, inverting the entire
waveform. At 90˚ right, only the right channel is inverted. At 90˚ left, only the left channel is inverted. A rotation of 45˚
produces results identical to the Pan/Expand effect, panning centered audio to the left or right, while panning
surrounding audio in the opposite direction.
Restricts the graph to the length you specify so the effect loops repeatedly over the course of the
Loop Graph
selection. Selecting this option enables a menu for specifying Period (how long the graph should be), Frequency
(how fast the loop should repeat), Tempo (how many beats per minute the loop should have), and Total Cycles (how
many times you want the graph to loop in the given selection). These settings interact; changing one changes the
others. If Loop Graph is deselected, the graph equals the length of the entire selection, so the effect doesn't loop.
