Available for download, iZotope RX 9 Advanced is the latest update to their audio-repair software, which is considered a staple within the recording, mastering, audio-for-video, and postproduction communities. The software can operate either as a standalone application or a plug-in for both Mac- and Windows-based DAWs and NLEs. From fixing common audio problems like noises, distortions, and inconsistent recordings, to repairing severely damaged audio using Spectral Repair, the software can transform previously unusable audio into something usable.
The advanced edition of RX 9 offers many new and updated modules and algorithms including Dynamic De-hum, Dialogue Isolate, Ambience Match, Spectral Editor, Restore Selection, and an Expandable History List.
The dynamic mode in De-hum instantly removes any amount of hum, interference, or wireless ring without artifacts or affecting the audio quality. In one pass, eliminate radio and transmitter interference, and camera and generator hum. In static mode, you can target hum with a fundamental hum frequency plus 16 harmonic bands above it, while dynamic mode allows you to learn and remove any amount of hum with up to 1024 dynamically variable notch filters.
Extract clean dialogue from its environment without artifacts using the new algorithm, Dialogue Isolate. This module features improved ambience preservation, leaving a more natural sounding dialogue, even when noise reduction is pushed to drastic levels.
The updated complex mode in Ambience Match allows you to seamlessly connect dialogue and ADR cuts with real background movement and textures. Quickly match ambiences never before possible, such as wind, ocean, crowds, traffic, and more.
For Logic users, The Spectral Editor allows you to clean up unwanted sounds directly within Logic without having to toggle between the RX Audio Editor and Logic Pro. It combines RX Spectral Repair, RX's spectrogram, and RX interactive tools that enable engineers and producers to identify and eliminate unwanted noises, from within Logic Pro.
Restore History allows you to roll back any audio selection to a previous step in your History list to get the best combination of audio processing form any point in time. This allows you to select a point in history for only the current selection. The History list has been expanded to 30 undo steps for quick reference.
All previous modules are in place for RX 9 including the Repair Assistant, multichannel support, high-quality resampling, dithering, and the rest of RX's classic features. As always, RX 9 can be used as a standalone audio editor (including standalone but connected to your host via RX Connect, or as your DAW's audio editor in the case of Logic Pro), although much of it can be used as a suite of plug-ins in any DAW.
It is designed to separate spoken dialogue from nonstationary background noise such as crowds, traffic, footsteps, weather, or other noise with highly variable characteristics. It can be particularly effective at increasing the level of dialogue in challenging low signal-to-noise ratio conditions.
There are two Quality settings:
- Good: for fast, high-quality processing that is optimized for speed over separation
- Best: the highest quality processing with fewer artifacts and better isolation at the cost of a longer processing time
You can also use the legacy Dialogue Isolate algorithm from before version 9—choose this in the settings.
In Static mode, you can target hum with a fundamental tone plus the 16 harmonic bands above it. In Dynamic mode, RX can learn and remove any amount of hum with up to 1024 dynamically variable notch filters.
Seamlessly connect dialogue and ADR cuts with real background movement and textures with Complex mode, allowing you to quickly match ambiences never before possible: ocean, wind, traffic, crowds, and more. Or, use Static mode to match stationary ambiences like a quiet room with a soft hum.
When hovering your cursor over an item in the History list with a selection made in the spectrogram, an icon appears in line with the text. Clicking this icon will restore your selection to that point in its history. This is the same as going back to that point in undo history, except only for your current selection.
- De-plosive eliminates every plosive from any dialogue track with transparency
- Leveler smooths any volume inconsistencies with an automatic clip-gain envelope; leveler is optimized for dialogue using intelligent De-breath and De-ess algorithms
- Instant Process tool is a one-click eraser for removing unwanted coughs, scene-interrupting sirens, and more
- Module Chain can process multiple modules at once, save your customized chains as presets, and execute them all with a single click, enhancing workflow and reducing mouse clicks
- Sync and integrate the RX Audio Editor with any DAW or NLE timeline using RX Connect
- Corrective EQ for removing harsh high frequencies, whines, rumbles, resonances, and distortion artifacts, and for accurately homing in on any problem-frequency areas
- Problem-oriented presets across several modules
- Signal Generator creates accurate test tones, calibration tones for postproduction delivery specs, and bleep tones for eliminating obscenities in dialogue
- Markers and regions (search) provide greater flexibility for those longer edits, with the ability to perform text-based searches of any markers, regions, and comments in the metadata of the audio
- Turn flawed audio into usable material by removing noises, distortions, and more
