If you have ever watched a blockbuster action hero whisper a romantic line immediately after a car explosion, or noticed that a character’s voice sounds slightly "studio clean" while they are supposedly lost in a rainy forest, you have witnessed the work of ADR Dubbing .
Here is everything you need to know about the invisible safety net of modern cinema. You might wonder: If the actor said the line on set, why not just use that audio?
Neural networks are also being used to "de-reverb" bad set audio, allowing filmmakers to use the original performance more often. But until sets become silent, ADR will remain a vital, invisible art. The next time you watch a movie and the sound is crystal clear during a hurricane, remember: you probably just heard a studio in Burbank, not the actual storm.

If the actor’s mouth was slightly open on set, the ADR line must have a slightly open vowel sound—otherwise, the visual "plosives" (B, P, M sounds) won't match.

Tom Hardy has famously called it "soul destroying."
In the film and television industry, ADR stands for . Outside of the US, it is often simply called "looping" or post-sync . While audiences often use the word "dubbing" to refer to translating Shrek into Spanish, professional ADR is something else entirely: it is the art of re-recording the original actor’s dialogue in a studio to improve audio quality or change performance.
