Royal Blue Audio

Welcome to my sound library shop.
I’m Kerthekan Balasubramaniam, a sound designer, re-recording mixer, and sound supervisor working internationally across film, documentary, animation, and interactive projects.

I work between studios in Frankfurt and Lisbon and collaborate with filmmakers and creative teams around the world. Depending on the project, I often build and coordinate small, focused teams to ensure both creative quality and technical precision throughout the audio post-production process.

The sound libraries you’ll find here are created from real production needs. They are designed to be flexible, well-organized, and ready for professional use — whether you’re working on narrative film, documentary, games, or experimental projects. My focus is on sounds that support storytelling rather than feeling generic or over-processed.
