Flex Time and Pitch overview
Flex Time—similar to what is often referred to as elastic audio in other applications—greatly
simplies the process of editing the timing of audio material. You can compress or expand
the time between specied points in an audio region without the need for more traditional
processes like cutting, nudging, and crossfading.
You edit the timing of audio material by choosing a Flex Time algorithm. When you choose
an algorithm, the contents of the audio track are analyzed for transients, or signicant peaks,
and any detected transients are marked in the audio regions. You then edit the timing using
ex markers. When you move a ex marker, the audio on either side of it is time compressed
or expanded. The initial boundaries within which this is done are determined by the
transient markers.
Flex Pitch allows you to quantize and edit the pitch of audio material. You edit the pitch of audio
material by choosing the Flex Pitch algorithm. The contents of the audio track are analyzed for
pitch using a pitch detection process, and the results are plotted on a pitch curve.
You can edit the timing of audio in the Tracks area and the pitch in the Audio Track Editor.
Flex Time is also available in the Audio Track Editor and Flex Pitch in the Tracks area, when
Show Advanced Tools is selected in the Advanced preferences pane.
