VideoStudio lets you stretch an audio clip to match video duration without distorting its pitch. Normally, stretching audio clips to fit the project results in a distorted sound. The time stretch feature will make the audio clip sound like it is just played in a slower tempo.
When you stretch an audio clip by 50-150%, the sound will not be distorted; however, if you stretch the clip below or above that range, the sound may be distorted.
You can also stretch the duration of an audio clip in the Timeline by holding down Shift and dragging the handles on the selected clip.
