Automated Dialogue Replacement in a film. A process where actors replace dialogue in a film or video. A typical ADR session involves not only the recording studio and voice talent, but often producers, directors, and vocal/dialogue coaches located in other parts of the country. Remote parties participate via ISDN, allowing everyone to interact in real time. The artists need to hear the original set dialogue, music, sound effects, directions from the production team and coaches, cues, playback of the re-recorded parts, and talkback from the control room.
