Process > Fit to Time

Process > Fit to Time stretches or shrinks the selection so that it ends at a specific time, expressed in either measure:beat:tick (MBT) or hours:minutes:seconds:frames (SMPTE) format. This command gives you a choice of modifying the events or modifying the underlying tempo. This is useful when you want to alter a portion of a project to have an exact length. The start time of the selection does not change, but the end time is altered as necessary to fit the required time interval.

Audio can be stretched or condensed up to a factor of 4 (e.g., it can be shrunk to as little as 25 percent of its original length, or expanded to as much as 400 percent of its original length).
