Mastering made for everyone
In the early 2000s, home-recording musicians and engineers wanted their tracks to sound like the radio but weren’t sure how to get there – many didn’t even know what mastering was. iZotope’s founders, feeling this need too, set out to create an accessible tool to give recordings that finished sound. And just like that, Ozone was born, evolving over the years into the backbone of countless masters – from bedrooms to Billboard.

AI tech that guides, not decides
In 2017, Ozone's AI-powered Master Assistant sparked the shift to faster, smarter, more accessible mastering. Using the analysis of thousands of professional tracks, Master Assistant was the first to create custom presets that match target sounds in seconds. And Master Assistant is just that, a creative co-pilot for engineers of all levels, saving precious time, supporting creativity, and taking the mystery out of mastering.

The cutting-edge of mastering tech
Doing the impossible is an Ozone tradition. Best-in-class neural nets let you unlock previously unreachable parts of your audio, solve previously unsolvable problems, and discover uncharted levels of control and creativity. If you’re tired of the tedious and craving the creative, Ozone is the answer.
