Our Services

  • Sound design means creating, recording, and shaping audio, effects, atmospheres, textures, to give visual stories real depth and feeling. We never shy away from building Foley ourselves, made for the scene, or take our field recorders to hidden and uncommon locations to create a unique feel that makes your story stand out

  • For your story to have a clear voice, it needs to have a clear dialogue. Our Pro Tools-certified editors remove noise, clicks, and pops, while keeping the performances intact. Quickly and meticulously, we make dialogue edits smooth and consistent, ready for mixing and broadcast across film, TV, podcasts, commercials, and online content.

  • We’re musicians at heart at KATSU Audio. Whether helping you choose the perfect licensed track, composing in-house or reaching out to our network of talented composers, we offer more than just composition services: we help you find the right tone for your story and audience.

  • Do you want these ocean waves more oppressive and chaotic? Or the wind more soothing and peaceful? Do you want silence to feel louder, or noise to feel more musical? Or you just want that “BOOJ” to shake your innards a bit more? To make your story worth listening to, we’re shaping every detail until it lands exactly right.

    For this, we provide professional audio mixing services in stereo, surround, and Dolby Atmos, so dialogue, music, and sound design translate well on any system, and deliver  format-ready mixes for any platform.

  • KATSU Audio’s sound design transformed our animation, adding depth and emotion. It reminded us how essential good sound is: it doesn’t just enhance visuals, it completes them.

    - Ignatz Johnson Higham, Director OOF Animation Ltd

  • KATSU Audio did a phenomenal job, turning our brief into a brilliant, creative soundscape that really brought our animation to life. They were friendly and professional during the notes and editing process, helpfully explaining technical details. I would recommend anyone looking for sound design that will complete and elevate your work to reach out!

  • Hervé at KATSU Audio is an absolute joy and a pleasure to work with. He approached our projects with the upmost professionalism and a highly collaborative spirit. He was very accommodating when it came to some challenging audio fixes and was able to deliver in a compressed timeframe. It was a frictionless experience, with everything delivered ahead of the deadline with minimal feedback needed from our team. I can highly recommend working with Hervé.
