RX 12 Advanced: Audio Restoration Suite by iZotope

RX 12 Advanced groups its toolset into modules for specific problems. Dialogue and voice work includes breath reduction and speech isolation. Signal cleanup covers bleed removal between sources and hum or rustle reduction. Music tools include Music Rebalance, which separates vocals, bass, percussion and other instruments for remixing or creating instrumentals.

Its Repair Assistant gives a faster route for users who want a guided cleanup rather than manual control. Module-level tools remain available for detailed, surgical edits.

New in version 12, Trim Silence automatically detects and removes audio gaps in long files, and the interface gains a larger Spectrogram, a module search and a resizable History panel.

Scene Rebalance is built for post production. It lets you adjust dialogue, music and effects levels independently, including on a mix without stems. Stems View splits audio into stems within Scene Rebalance, Music Rebalance and Dialogue Isolate, so the full toolkit can be applied to individual parts before everything is recombined for export.

For music producers, Music Rebalance and De-bleed offer real-time plugin versions, which suits tracking and mixing sessions as well as offline cleanup.
