Changing Speed - Ulead MEDIASTUDIO PRO 7 User Manual

368
The first control point in the graph defines the start-fade amplitude, the
second and third points for the middle of the fade and the fourth point for
the end-fade amplitude (where 100% is normal amplitude). To help smooth
out the fade, select a Transformation curve option. A Linear fade
produces a constant fade, while an Exponential fade begins slowly and
ends quickly. The Logarithmic fade starts quickly and fades more slowly.
For best results, it is a good idea to first experiment with a variety of
different settings.

Changing speed

Changing the speed of an audio file is a useful way to increase or decrease
its duration, as well as for producing interesting distortion effects. When
you click Effect: Speed, the Speed dialog box opens with a slider for
adjusting the speed. Moving to the right slows down the file, thereby
increasing its duration. Moving to the left speeds it up, decreasing its
duration accordingly.
