Audio Post-Production

Say it with sound

The boom of an explosion. The swoosh of a lightsaber. Seeing isn’t the only way of believing: great sound can move people in ways that no other format can match. It’s an art that takes a long time to master – and we've been perfecting it for over 35 years.

VSI offers a range of audio post-production services for film, TV, video games, corporate content, media and beyond. We mix audio in all formats to match all deliverables. Our sound design work covers FX and music editorial and creation, including rebuilding M&E mixes for international versions. We pride ourselves on our multilingual ADR capabilities, as well as our re-versioning expertise in editing audio to match new picture edits.

In our state-of-the-art facilities, you’ll find expert engineers and the latest hardware and software. Our extensive global network allows us to call on the right talent and technology to meet any brief on any platform – from broadcast to video on demand, to smartphones. No project is too big, and no deadline is too tight. 

We know what it takes to make people sit up and listen. Let us show you.
