What is the function of Shuffle Mode in Pro Tools?

Shuffle Mode in Pro Tools is designed to facilitate the rearrangement of audio clips on the timeline without leaving any gaps or overlaps. When this mode is engaged and a clip is moved, the surrounding clips automatically adjust their position to fill in any spaces created by the movement. This snapping behavior is particularly useful in editing scenarios, where maintaining the continuity and flow of audio is critical, especially in arrangements that require precise alignment and timing.

In contrast, the other functions described in the other options do not accurately represent the behavior of Shuffle Mode. Stretching clips over the timeline relates more to Time Stretch or Elastic Audio functions. Randomizing playback of clips is not a characteristic of Shuffle Mode, as it focuses on the linear arrangement of audio, while duplicating clips would fall under Copy and Paste functions rather than specific manipulations associated with Shuffle Mode.
