Position track controllers
Position track controller types include some of the common default controllers and can be assigned to the
Position track. They typically work with three unique values representing the X-, Y-, and Z-axes. These con-
trollers can be assigned from the Animation ➪ Position Controllers menu. Many of the controllers found in
this menu also are found in the Rotation and Scale Controllers menu.

Audio controller
The Audio controller can control an object’s transform, color, or parameter value in response to the ampli-
tude of a sound file. The Audio Controller dialog box, shown in Figure 34.18, includes Choose Sound and
Remove Sound buttons for loading or removing sound files. You can access the Audio Controller dialog box
by right-clicking on the track where the Audio Controller is assigned and selecting the Properties menu
from the pop-up menu or simply double-click on the track.
The Real Time Control drop-down list lets you specify a device to control the system. To control the sound
input, you can specify a Sample Threshold and Oversampling rate. You also can set Base Point and Target
Point values for each axis. The Channel options let you specify which channel to use: Left, Right, or Mix.
