ADR

What ADR means

ADR stands for Automated Dialogue Replacement, sometimes called Additional Dialogue Recording or looping. It is the process of re-recording dialogue in a studio to replace production sound that cannot be used, then fitting the new line back into the scene so precisely that the audience never notices.

The reasons are usually practical. A plane passes overhead. The boom catches wind. An actor turns away from the microphone. A line reads wrong in the edit and needs a different intention. A word has to change for legal reasons or for a regional release. In every case the picture is locked and the dialogue has to be rebuilt around it.

ADR is not dubbing

The two get confused constantly. Dubbing moves content into another language, with a different actor and a different audience. ADR replaces dialogue in the same language, usually with the same actor, and the goal is invisibility rather than translation. A film can need both, and the workflows barely overlap.

Why ADR is difficult

A studio sounds nothing like a location. The original line was recorded in a room with its own reverb, background and microphone perspective, and the replacement has to sit inside that. Match the performance but not the acoustic and the line jumps out. Match the acoustic but not the energy and it feels dead.

The performance side is harder still. The actor is standing in a quiet booth trying to recreate a moment they played weeks ago on set, at the right pitch of emotion, in sync with their own mouth on screen. Most bad ADR is not a technical failure. It is an acting problem that nobody directed.

What an ADR director does

The ADR director is the reason a replaced line survives the mix. They watch the original take, work out what the performance was actually doing, and then get the actor back to that state in a room with no scene partner and no set.

In practice that means calling which takes to keep, correcting drift in energy rather than only in sync, protecting the actor's voice across a long session, and knowing when a line is close enough that pushing further will make it worse. On a multilingual project the director also carries responsibility for the adaptation reading naturally in the target language while still fitting the mouth.

What happens in an ADR session

The actor watches the line loop with three beeps, or a visual streamer, and performs on the fourth beat. The engineer matches microphone and distance to the original recording. The director works the performance until it sits. Good sessions move through a lot of lines quickly because the preparation was done before anyone stepped into the booth.

How we work

• Recording to picture with looped playback and beeps or streamers
• Microphone and perspective matched to the original recording
• Direction focused on matching energy and breath, not just words
• Processing to blend the line into the production track
• Delivery as separated stems ready for the dub mix

When the original actor is unavailable

Sometimes the actor cannot be reached or the schedule has closed. We cast voice matches, actors whose texture and delivery sit close enough to the original that a replaced line passes unnoticed, and we audition against the actual footage rather than a description.

Send the picture and the line list. We come back with a fixed price and, where a voice match is needed, custom auditions recorded against your footage. Typical turnaround for a quote is within 24 hours.
