There are two success criteria for a great video. The first is incredible visuals, and the second is the rock-solid sound design. Having professional camera equipment doesn't matter if the audio in the final product is full of unequal volume and background noise. That's why sound design companies are so important!

We have compiled the best sound design companies in London right now. So if you need sound effects or mixing and mastering for your next project, then look no further!

We would have regular meetings with the team on site at the Science Museum and also were lucky enough to be invited to the grand opening, where the Queen herself was a guest and sent her very first tweet: “It was a pleasure to open the Information Age exhibition today at the @ScienceMuseum and I hope people will enjoy visiting.
