Bigmouth’s expertise in cinematic sound design and voice production brings a distinctive, story-first approach to features, high-end documentaries, and scripted television.

We specialise in crafting immersive, emotionally resonant soundtracks that enhance storytelling and elevate every frame. Our end-to-end services include sound design, ADR, voice direction, and final mix - all delivered from our Glasgow and London studios.

We mix in Dolby Atmos for both theatrical and broadcast formats, and our boutique, founder-led approach ensures creative continuity and personal attention on every project - whether supporting independent filmmakers or larger-scale productions.
