Using the Audio Stretching Tool
You can time stretch all or part of an audio file to change the amount of time it occupies.
When you stretch an audio file, the length of time changes but not the pitch (letting you
fill dialogue, music, or other audio to a specific amount of time). For audio files with music
or other repeating patterns, stretching the file changes the tempo of the music without
changing the key. The range of the Audio Stretching tool is limited to between 25 percent
to 400 percent of the length of the original audio.
