About

Brand-grade ears, the whole signal chain.

JP Dutreuil — Hrmonik, audio engineer & producer

I'm JP Dutreuil, the engineer behind Hrmonik. Most recently, through Rose International, I provided Audio Engineering III services for Meta (Jan 2024–April 2025) — building Foley and sound design for video game titles, mixing and mastering audio for game projects and a music initiative, and writing AI-assisted automation in JavaScript (SoundFlow) to speed up the work. That's the part most engineers can't offer: I script my own pipeline.

That builds on seven years (2016–2023) as a full-time Immersive Audio Producer and Mix Engineer at Salesforce — designing and mixing sound for the Salesforce World Tour Keynote featuring Metallica, the Think Outside the Quota series, immersive activations across Dreamforce, and the Blazing Trails podcast. Earlier I consulted for Dolby Laboratories on new audio technologies, after training as an electrical engineering technologist at RIT and going deep into sound at Pyramind Studios in San Francisco.

I'm Avid Pro Tools HD certified (Operator, Music) and work across immersive sound design, dialogue and VO/ADR/foley editing, and mixing & mastering in both analog and digital rigs. Post-production and mixing/mastering delivered remotely, for clients anywhere, with DJ dates available to travel.
