  • To "loop" is a term used in audio post production where an actor re-records his/her voice in a studio setting. This term is currently often replaced with the term "ADR" or Automated Dialogue Replacement. This is used when the original audio that was recorded on set was poor/damaged/lost etc. The term "loop" itself refers, as much of the film industry terminology does, to the old days where the actor was shown a continual film loop of the scene he/she was recording so that they would be able to synchronise their voice with the performance that was shot at an earlier date. Now looping or ADR is performed using computer software.
