ABSTRACT
Voiceovers should usually sound different than dialog. That is why they are recorded using different techniques. There are three basic kinds of mics suitable for voiceover work: dynamic, condenser, and ribbon. Each has its advantages. Because the foil has so little mass, the ribbon can be extremely accurate—particularly on relatively loud sounds that lack extreme highs, like the human voice. The film was cut into individual loops for each line of dialog. The loop would run continuously while an actor tried to match the lip movements. Streamers are usually generated in video by the automatic dialog replacement (ADR) equipment, which may be part of a specialized audio workstation. Traditional ADR can be intimidating to an actor. A modern alternative is to make sound dominant. To fine-tune ADR, one can use software like VocALign; it analyzes the guide track at critical frequencies, then makes tiny edits in the new track to make it match.
