Key Points

  • iZotope launched Ozone 12, an AI-powered mastering suite with tools to separate instrument stems and restore dynamics to compressed audio.
  • The new "Unlimiter" feature revives crushed transients, addressing challenges in remastering old or poorly mixed tracks.
  • Ozone 12 offers a "Custom Flow" for users to direct the mastering process, enhancing creative control for artists.
  • The update includes AI-powered tools like Stem EQ and a new Maximizer algorithm to increase loudness without distortion.

Audio software developer iZotope has launched Ozone 12, the latest version of its AI-powered mastering suite, introducing new machine-learning tools that can separate instrument stems, manage low-end, and even restore dynamics to overly compressed audio. The update signals a deeper push into assistive AI that aims to give artists more control over the final sound of their tracks.

  • Guide, not decide: iZotope's AI assistant now features a "Custom Flow" that lets users direct the mastering process by choosing specific processing modules and setting genre and loudness targets. The company says the goal is to create an intelligent co-pilot for artists, not a one-click replacement for them.
  • Reversing the loudness wars: The most intriguing new tool is the Unlimiter, which analyzes overly compressed audio and revives crushed transients to restore dynamic life. Early hands-on reports have described the feature as "remarkably effective" and "sort of magic," potentially solving a major headache for engineers needing to remaster old or poorly mixed tracks.
  • Fix it in the master: The update also bundles in several other AI-powered surgical tools. Stem EQ separates a stereo file into vocals, bass, drums, and instruments for individual processing, while a new algorithm in the Maximizer aims to increase loudness without adding common distortion artifacts.

Ozone 12 is available now in three tiers, with the entry-level Elements priced at $55, the Standard version at around $220, and the full-featured Advanced version costing just under $500.
