Doug Mountain Restores Hollywood History In Dolby Atmos

With a career spanning over four decades, Veteran Re-recording Mixer and Supervising Sound Editor Doug Mountain has built a career out of elevating sound in film and television — and most recently, reviving the classics.

He has worked on acclaimed series like "Community", "The Walking Dead" and "All American", and served as a consulting engineer for the GRAMMY® Awards for over 25 years. Today, he is widely known as what he jokingly calls “the Atmos Remix King,” with nearly 40 feature film remixes under his belt.

Most recently working from his custom Dolby Atmos mix room, Mountain has become a key figure in remixing many studios' historic film libraries for immersive sound formats, including Dolby Atmos and Dolby Vision. At the heart of his workflow is a selection of NUGEN Audio plug-ins, including Halo Upmix, which he credits as essential to faithfully modernising the beloved films. "Halo Upmix is the cornerstone of what I do," he said. "It's instrumental, especially for music upmixing and backgrounds. It provides a fuller, smoother sounding upmix compared to a lot of other similar tools out there."

Mountain often works with limited source material, such as mono dialogue, isolated music and effects stems or legacy 5.1 mixes. His goal is to breathe new life into these elements without compromising their historical integrity. "A lot of mixes from the ‘90s have strong front and rear elements, but we're missing the middle of the room," he said. "Halo Upmix helps fill that space and makes the soundstage feel complete. It tells me what’s missing and helps build it up naturally."
