Automated dialogue replacement, or additional dialogue recording (ADR), is the process of re-recording dialogue by the original actor after the filming process to improve audio quality or reflect dialogue changes (also known as “looping” or a “looping session”). ADR is also used to change original lines recorded on set to clarify context, improve diction or timing, or to replace an accented vocal performance. In the UK, it is also called “post-synchronisation” or “post-sync”

Contrary to the name, it is far from automatic, and a highly skilled process matching both the technical sound of the original location recording and the performance of the actor.

Our voiceover recording studio in Wimbledon, London offers replacement dialogue and voiceover recording either as wild-lines or sync to picture, depending on the nature of the material and whether or not the original performance is on-screen.

We favour a Sennheiser MKH416 microphone for ADR recording sessions since this is a good tonal match for a lot of production dialogue, and recordings made with the 416 are easy to blend with the original performance. The Neumann U87 is used more for voiceovers and voices for animated shows due to the increased detail offered by this excellent LDC mic.

Our voiceover recording studio uses a variety of techniques to match ADR recordings to the production sound, ranging from EQ and dynamics processing to spatial techniques as well as time and pitch alignment tools and advanced editing techniques to match lip-sync and maintain a natural performance.

Before you book an ADR session, get in touch and have a chat about what you’re trying to achieve with the recordings. We can work minor sonic miracles with audio, so may be able to save you time and money by enhancing and restoring your production audio.
