Automated Dialogue Replacement (ADR) is a post-production process in filmmaking where actors re-record their dialogue in a studio to improve audio quality or alter lines. During the initial filming, background noise, technical issues, or other disruptions can compromise audio clarity. ADR addresses these challenges by allowing actors to reperform their lines in a controlled studio environment, ensuring that the dialogue is clear and matches the on-screen action. This process not only helps in fixing audio issues but also provides opportunities to refine performances and adjust dialogue to better fit the final edit.

In a studio, ADR is typically recorded in a soundproof booth equipped with high-quality microphones and monitoring systems. Actors watch the film scenes on a screen while they perform their lines to synchronize their speech with the actors' lip movements and the scene's timing. Sound engineers use specialized software to match the re-recorded dialogue with the original footage, making precise adjustments to ensure seamless integration. The result is a polished and cohesive auditory experience that enhances the overall quality of the film.
