To convince the human eye that it is perceiving motion, one needs to watch film at a modest 24 frames per second. But to convince the human ear, we need a whopping 44,100 samples per second to accurately perceive sound. The human ear is so sensitive to sound, and to the human voice, that only the highest quality audio recording can please even the casual listener. For production supervisors, post production supervisors, and directors, there is no escaping the need for pristine audio. Automatic Dialogue Replacement, or ADR, has the specific purpose of capturing new dialogue that most closely matches an actor’s previously filmed performance. Voiceover recording traditionally refers to audio that accompanies a visual presentation of, say, a film or television commercial. For instance, the narrator of a scene in a film, the voice of the driver thinking about the experience of driving a car in the advertisement, an audiobook, an animated voice—all of these are captured using specialized studio mics.
