iZotope RX 12 Advanced Update from RX 11 Advanced — Free Download

Purpose and Scope

RX 12 Advanced Update from RX 11 Advanced is an upgrade path for current RX 11 Advanced owners, providing access to the latest version of the RX 12 suite. This edition includes the RX Editor standalone application plus a comprehensive collection of RX plugins, modules, and additional tools for audio repair and restoration.

The upgrade introduces a set of new and rebuilt modules focused on intelligent separation and noise reduction. Scene Rebalance, exclusive to Advanced, separates complex audio scenes into distinct dialogue, music, and effects components, enabling detailed editing and releveling. The new Stems View allows mixed audio to be split into track-based stems using Scene Rebalance, Music Rebalance, or Dialogue Isolate, after which each stem can be edited with the full RX toolkit.

Key Capabilities

Several modules in this update have been rebuilt or refined using machine learning. The De-bleed module, which reduces cross-signal interference like headphone bleed on vocals, has been rebuilt for sharper accuracy. A new De-bleed real-time plugin provides instant leakage reduction.

Music Rebalance has also been upgraded with offline neural nets for pinpoint stem isolation, and a new Music Rebalance realtime plugin enables source separation of vocals, bass, and percussion in a standalone plugin. Additionally, the Advanced-only Trim Silence module automatically detects and removes silent regions in long audio files, saving time on tedious edits.

Workflow Enhancements

Design updates in RX 12 aim to streamline the user experience. The Spectrogram display is larger, a new module search helps locate tools quickly, and a resizable History panel improves session navigation. The interface has been refreshed for a cleaner look, which can accelerate the editing process.

The Stems View feature exemplifies the new workflow: after splitting a mix into stems, you can apply any RX module to a specific stem, allowing targeted processing. This is particularly useful for rebalancing scene mixes or isolating dialogue from music and effects.

Practical Applications

This upgrade is best suited for professional audio post-production for film and TV, where Dialogue Isolate and Scene Rebalance help clean noisy dialogue or separate elements for mixing. Music Rebalance is useful for remastering or creating stems for live performance, while De-bleed is valuable for fixing headphone bleed in vocal recordings and drum isolation. Breath Control is effective for polishing dialogue and vocal tracks by removing unwanted breaths.

Trim Silence saves time when preparing long recordings for editing. The real-time plugins for De-bleed and Music Rebalance allow for immediate processing during a session, ideal for quick checks or live use. Because this is an upgrade, it is intended for existing RX 11 Advanced users, ensuring they have the latest tools without a full new purchase.
