What is iZotope RX?
iZotope RX 12 Advanced repairs damaged, noisy, or poorly recorded audio through a standalone editor and a large set of DAW plugins. It targets post-production, music, broadcast, podcasts, video games, and other projects where rerecording is difficult or impossible. Its machine learning tools can isolate dialogue, separate stems, reduce noise, and restore details while keeping manual spectral editing available.
Scene Rebalance can independently adjust dialogue, music, and effects from a finished post-production mix, even when separate stems are unavailable.
RX 12 Advanced fits dialogue editors, re-recording mixers, forensic audio specialists, and producers handling demanding restoration work. It is expensive and takes time to learn, especially when you move beyond Repair Assistant into detailed spectral repair. The payoff is unusually deep control over difficult audio problems inside both its editor and supported host applications.
