CHAPTER 2: EDITING AUDIO FILES 259
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.
Performing a stereo pan
If you have a stereo file, you can pan the audio so that it sounds as if the audio
moves from one speaker to the other, creating a "surround sound" effect. To do
this, click
Effect: Pan and in the Pan dialog box that opens, alter the fade for each
channel accordingly. For example, a start and end level of 0% results in complete
silence while 100% leaves the output unchanged. As with the Fade command, you
can choose between Linear, Exponential and Logarithmic changes to help smooth
the effect.
