Mastering Dolby Atmos Music with Justin Gray – Approaches To Immersive Object-Based Mastering

Dolby Atmos mastering is a complex and still-evolving discipline that blends technical understanding with critical listening. At its core, it’s about translating an artistic vision across many playback environments while preserving the intent of the original mix.

Unlike stereo, Atmos is not a fixed format. It’s an adaptive, object-based system that renders music differently depending on the playback context, whether that’s a full speaker array, a soundbar, or headphones. This flexibility creates creative opportunities but also introduces new challenges for consistency and translation.

Mastering this format isn’t about chasing numbers or applying broad processing. The focus is on perceptual balance—how a mix feels across different listening systems—and on making subtle, often invisible adjustments that help the music translate without altering its character.

My approach typically involves working at the stem and object level, evaluating how spatial relationships, dynamics, and tonal balance behave across formats. When adapting existing stereo releases, the goal is alignment: respecting the original while leveraging what immersive audio can offer.

Because immersive playback systems and binaural rendering continue to evolve, Atmos mastering requires ongoing reassessment rather than fixed assumptions. A fresh perspective can be especially valuable, even for experienced mixers working in excellent rooms.

Ultimately, this work is about serving the music. The goal is to support the artist’s intent and create a listening experience that feels coherent and engaging—regardless of how or where the music is played.

In the video below, I go deeper into how I approach Dolby Atmos mastering and the practical considerations that shape this art form.
