About

Brian Sloss in his studio

My favorite part of working in sound is collaboration. There’s something incredibly rewarding about watching everyone’s ideas build on each other until a project becomes so much greater than any one of us could have created alone.

I’ve been fortunate enough to sound design and mix films that have screened at SXSW, Tribeca X, Fantasia, HollyShorts, LA Shorts, Fantastic Fest, and more.

Beyond film, I have a passion for building audio tools, recording sound effects, creating sound installations, and just about anything that comes alive through audio. Along the way, my sounds have wiggled their way into places I never expected, from medical devices to game shows. I’m excited to see where they’ll end up next.

I’m based in the Seattle area and collaborate with clients both locally and remotely from my Dolby Atmos studio. Whether you’re local or halfway around the world, I’d love to hear what you’re working on.
