What does ADR mean in UNCLASSIFIED

ADR stands for Automatic Dialog Replacement. It is a post-production technique used to replace audio recorded during filming with pre-recorded dialogue.

ADR is typically used when the original audio recorded on set has poor quality, may need to be replaced due to legal or logistical reasons, or is not suitable for broadcast.

In most cases, it's the actors who originally provided the dialogue who perform ADR. This ensures that any new lines are matched as closely as possible with the original performance.

ADR can be recorded anywhere from professional grade sound studios to home studios with basic equipment and acoustic treatments. The actor will usually perform their lines while watching a video playback of their performance taken from the set and deliver their lines in tandem.

One of the main benefits of using ADR is being able improve the overall audio quality of a recording by removing background noises and distortions present during filming and replacing it with clean audio recordings taken in an environment where these distractions have been eliminated. Additionally, it also allows filmmakers more control over how their lines are delivered by allowing them to refine performances if needed without having to return to set.
