About SisterBoss

SisterBoss is a full-service sound design and audio post-production studio based in downtown Minneapolis. Located in the historic Lumber Exchange building, we specialize exclusively in sound design, mixing, and voice recording for professional productions.

We work with ad agencies, production companies, editorial teams, and independent filmmakers to create clear, compelling, broadcast-ready audio, delivered reliably and without friction.

We believe great sound is felt as much as it’s heard — and it should serve the story first.

What we do best

• Sound design and mixing for advertising, film, video games, and streaming content

• Voiceover recording sessions, in-studio and remote

• Audio mixing, finishing, and delivery of spec-compliant, broadcast quality audio for TV, terrestrial radio, social, and digital platforms

• Voiceover recording (in-studio & remote)

• Sound design and mixing

• Audio cleanup, restoration, and repair

What sets us apart

• Navigating specs and formats so you don’t have to (seriously, we’ve got decades of experience)

• A trained ear for what actually matters in a mix

• Problem-solving instincts honed on imperfect audio and tight timelines

• A collaborative studio experience that respects your creative vision

• Clear communication, reliable delivery, zero ego

Our approach

SisterBoss grew from a deep foundation in sound and music into a studio focused entirely on audio post-production. We combine technical precision with creative instinct, collaborating closely with our clients to elevate every project, and keep the process calm, efficient, and dependable from start to finish.
