Dolby Atmos Mastering

As a Dolby Atmos mastering engineer it my goal to ensure that your creative vision reaches its full potential in this immersive audio format.

Justin Gray's YouTube Channel


  • It was awesome working with Justin. A true professional who cares about all that nerdy audio stuff to make sure every artist sounds GREAT. Max Kerman (Arkells)

  • We were thrilled when we found out Justin would be up-mixing our tracks to Dolby ATMOS. His fine attention to detail and talent made our music come alive in the immersive audio world! The Command Sisters

  • My Dolby Atmos music mixes sound amazing, but they need to be mastered properly by someone who has a specific understanding of mastering immersive audio content. Justin Gray has been able to take my Atmos mixes to the next level and make them sound even more immersive, and incredibly musical. Derek Brin

  • Justin’s commitment to the art of Atmos music mixing is incredible. It is rare enough to find someone with his technical know-how; someone who knows how to mix in immersive formats properly. More than his unrivaled technical base, Justin possesses what is so rare in any new artistic form: artistry. He understands when the bells and whistles of immersive audio support the music, and when they don’t. For Justin, it’s always about the music, and immersive technology is in service of that. I’ve not met another immersive engineer like him in that regard.
