Looping

Looping is another term for ADR (Automated or Additional Dialogue Replacement). The name comes from the original method for dialogue replacement where a piece of film was cut into a loop. This loop allowed for automatic repetition when recording, which helped enable a good performance from the actor by allowing him or her to make a series of successive takes.

Looping is also an editorial practice of repeating an audio segment. This method can be used when creating clean backgrounds from a source effects stem, for example. The clean section is looped, i.e., repeated over and over, in order to fill the entire length of a scene.
