RX 12 Brings Faster Audio Repair and Expanded Stem Editing

iZotope has released RX 12, continuing the evolution of its long-standing audio repair and restoration platform. The software has been a staple across music production, post-production, and broadcast environments for years, and this update focuses on expanding control while improving speed across the workflow.

RX 12 operates as both a standalone application and a suite of plugins, which allows it to sit directly inside a DAW or function as a dedicated editing environment. That flexibility has always been a defining part of RX, and it remains central to how the tool is used across different types of projects.

The platform now includes over 50 modules designed to address a wide range of audio issues, from noise reduction and spectral repair to dialogue cleanup and tonal balancing. These tools are accessible through a visual spectrogram interface, where users can identify and remove unwanted sounds with precision.

Expanded control over stems and mix elements

One of the more important additions in RX 12 is the introduction of Stems View. This feature allows users to visually split audio into separate elements such as dialogue, music, and effects. Once separated, any of RX’s processing tools can be applied directly to those elements without affecting the rest of the signal.

This type of control opens up new workflows for both music and post-production. Producers can isolate specific components of a track for detailed edits, while post engineers can rebalance mixes without returning to the original session files.

The new Scene Rebalance module builds on that capability by allowing independent adjustment of dialogue, music, and effects within a mix. This is particularly useful in situations where access to the original multitrack session is not available. Instead of working around a fixed stereo file, users can reshape the balance with a higher level of precision.

Workflow improvements focused on speed

RX 12 also introduces a series of updates to reduce friction during editing. The Repair Assistant has been refined with improved machine learning models, allowing it to identify issues and propose fixes more quickly. Users can then adjust those suggestions to meet the project’s needs.

Additional modules, such as Trim Silence, help manage long recordings by automatically identifying and removing unnecessary sections. This is particularly useful in dialogue editing, podcast production, and long-form audio work.

The interface has also been updated with a larger default spectrogram, a searchable module system, and an expanded history panel. These changes support faster navigation and allow users to track edits more easily across complex sessions.

Position within modern production workflows

RX 12 continues to serve as a central tool for audio cleanup and restoration. Its combination of visual editing, machine learning, and modular processing places it in a position where it can handle both corrective work and creative manipulation.

The software is used across a wide range of applications, including music production, film and television post-production, podcasting, and game audio. That versatility comes from its ability to address both small, detailed edits and larger structural changes within a file.

RX 12 is available in multiple editions, including Elements, Standard, and Advanced, each offering different levels of access to the full toolset. It is also included in the RX Post Production Suite.

For producers and engineers working with complex audio material, RX 12 remains a comprehensive solution for identifying, isolating, and correcting issues within a single environment.
