What
We Do

Your Story, Our Sound.

Swell Sound is a full-service creative audio studio that sits in the gap between music houses and post-production houses. Founded in 2009 by Elad Marish, based in the Bay Area, California, we do music, sound design, mix, dialogue, voiceover, sonic branding, and music supervision under one roof: Full-stack creative audio for ad agencies, brands, production companies, and high-end content creators. We love to press "record."

Who We Are

Elad Marish founded Swell Music + Sound in 2009, after years spent playing in Bay Area bands, engineering under other people's direction, and slowly realizing he liked shaping a track more than fronting one. The name came to him on a surf trip in Mexico - a triple entendre he couldn't shake.

His pitch for why Swell exists, in his own words: "Most post houses have engineers but no musical brain. Most music houses don't do post. We crush both."

Since 2009, Elad and the Swell team have scored, mixed, and built sonic identities for Nike, the Golden State Warriors, United Healthcare, Meta, Atlassian, and CrunchLabs - working alongside agencies including Turner Duckworth, Leo Burnett, Cutwater, and Mekanism. Elad still takes the marquee mix jobs personally and runs supervision and final mix on most of what comes through the door. He's a former National President of the Association of Music Producers (AMP), and in 2026 co-founded Topshelf Music, Swell's curated music licensing platform, with Michael Frick.

Our
Studio

Come play with us. Swell's home is a 40-year-old room at Swell Studios in Richmond, with real analog bones - Neve, Neumann, Fender, Gibson - married to a full modern digital workflow. Elad's line on it: "We love mics, preamps, room sound. We love digital workflow, plugins, cloud sessions. The marriage of those two is what makes Swell sound like Swell."
"We love working with Swell! We’re so happy to have found amazing audio post partners in the Bay."
Douglas Stivers
Executive Producer, Cutwater Agency
"I've had a great experience working with Swell for voiceover and sound design. They're true pros who make the technical side easy to navigate and their friendly, approachable style makes the whole process enjoyable."
