Welcome to VSI Lisbon

A sound collaboration

VSI Lisbon grew out of a joint venture between three companies: VSI, Billyboom Sound Design and Agencia Munoz. With a combined experience of more than 40 years, we have grown to become the foremost media localisation company in Portugal.

We handle all audio-based services, including recording, sound design and original soundtrack composition. But our core strengths lie in our expert dubbing and mixing services, delivered in multiple languages, most notably European Portuguese. From promos, advertisements, theatrical movies and TV, to original sound tracks, animation, documentaries and special effects, we work on all kinds of media.

Our state-of-the-art studios are located in the same building as an audio-visual content producer, an advertising agency and an Emmy-winning graphic motion team – all of whom we have partnered with over the years. This gives us a unique and multi-faceted approach to our projects, as well as an added depth of professional and generational diversity.

With an existing portfolio of clients hailing from the radio and television industries, as well as the Portuguese government’s recent incentives to attract foreign productions, we are growing fast. Our team’s mission is to always deliver work to the highest of standards, on time and within budget.

Our services

We are experts in all things audio. Our services include audio post-production, multi-channel mixing and dubbing. In addition, we have great working relationships with several local media companies, enabling us to offer a versatile and collaborative approach to your project.


Exceptional dubbing goes unnoticed. It’s an art. An exercise in precision. A creative and technical challenge that can make or break a project in any market. And it’s a challenge we relish.

Audio Post-Production

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 we've been perfecting for over 33 years.


When it comes to storytelling, one thing is sure: what people hear is just as crucial as what they see. The right voice-over can elevate content to unforgettable status. And we know what it takes.
