Effect group
Each waveform has an Effect parameter, which can
be one of the following:
Add—Causes the current waveform’s value to be
added to the previous waveform’s output. This is
the default.
Multiply—Multiplies the previous waveform’s
output by this waveform’s value.
Clamp A b o v e —Limits the previous waveform’s
output to be above this waveform’s value.
Clamp Below —Limits the previous waveform’s
output to be below this waveform’s value.
Characteristic Graph
Characteristic Graph shows one of three displays,
controlled by the radio buttons below the display.
This Wave—Shows the current waveform only,
independent of all other waveforms.
This Output—Shows the output of the current
waveform, including all previous waveforms.
Fin al O u t p u t—Shows the output of all the
waveformsinthelist. Youcanalsoseethe
final output by turning on the Track View —
Curve Editor display for the track which has the
waveform controller assig ned.
All displays show the output graph of the controller
waveforms i n a solid dark l ine, w ith the zero line
drawn in a dotted gray line. Two numeric displays
to the rig ht show the high and low r ange of t he
waveform curve. The graph automatically scales
vertically to fit the waveform output curve, and
scales horizontally to two times the period of the
longest-period waveform.

Adding a sound track to your animation allows
you to synchronize animation to sound. Add a
sound track to lip-sync a character speaking, for
example.
Interfa ce
Audio File group
Use this group to add and remove sound files from
the controller, and to adjust amplitude.
Cho ose So u n d —Displays a standard file selector
dialog. You can choose .
wav and . avi files.
RemoveSound—Removes any sound file associated
with a controller.
