Ozone 12 Advanced Crossgrade from any paid iZotope product: Mastering Suite Plugin

Ozone 12 includes Bass Control for adding drive, punch and balance to the low end, and Unlimiter, which iZotope describes as an undo button for overly compressed audio. Unlimiter uses machine learning to bring back lost transients, and you set it with a threshold or the Learn button.

Stem EQ lets you EQ vocals, bass, drums and instruments separately inside a stereo master. The Clarity, Impact and Transient/Sustain modules give you control over smoothness, microdynamics and transient and sustain content across any Ozone module.

The IRC 5 Maximizer mode is the newest limiting algorithm in the Maximizer, and the Stabilizer module adds 25 new genre targets for adaptive mastering EQ.

Master Assistant can be run in a Custom flow, where you choose genre targets or references, toggle modules and set loudness levels. The Assistant View gathers your preset and signal chain in one place for fine-tuning.

The suite is available in VST3, AU and AAX formats, all 64-bit, for Windows 10 and 11 and macOS Ventura through Sequoia. It is compatible with Apple silicon native processing and runs in hosts including Logic 11, Pro Tools 2025, Ableton Live 12, Studio One 7, FL Studio 25, Cubase 14 and REAPER 7.
