New Denoiser Algorithms

New Global Smoothing control reduces the distracting, watery artifacts introduced by most denoiser algorithms and a high-frequency enhancement avoids the dullness commonly associated with noise suppression.

Improved Declick & New Decrackle

Declick features improved click detection and new Decrackle algorithm designed to treat continuous background crackle from vinyl and older media.

Freehand Selection & Magic Wand

New Lasso, Brush and Magic Wand tools allow natural, freehand selections of problem sounds. Additionally, the Magic Wand can automatically select a sound and its harmonics for incredibly fast editing.

Improved Batch Processing

Updated batch processor streamlines your workflow by letting you chain multiple modules, process multiple files and use multiple CPUs.

Intelligent Hum Module

Automatically identify the base frequency of hum for precise removal. The module will even recommend when the Denoiser should be used to more effectively treat certain kinds of hum.

Session Support

Your edit history is automatically saved when you quit and reloaded when you restart. The entire state of the program including your selection is saved. This new feature also works in the event of a computer crash or power outage, so you can get back up and running immediately.

Channel and Phase Operations

New Channel Ops module features left/right channel mixing and arbitrary phase rotation operations, both of which are crucial when restoring audio transferred from tape.

Pre-roll and Post-roll Support

Customize the amount of audio played before and after an edit for context when previewing edits.

Fade Support

The Gain module now includes support for fades with several fade types.

RX Advanced only new features:

Adaptive Denoiser Mode

Deconstruct

This new class of audio manipulation tool intelligently separates audio into tonal and noisy components allowing independent control over each.

3rd Party Plug-in Support

Host your DirectX, Audio Unit and VST plug-ins inside of RX taking advantage of RX's spectral selection to process only parts of an audio file. Also, extremely useful when using the Batch Processor and Compare features.

Zotope Radius

Radius® is iZotope's world class time-stretching and pitch-shifting algorithm. Change the tempo without affecting the pitch or tone of the performance. Instrument attacks, percussive hits, and the sound stage remain untouched, even at extreme stretches.

Export History as XML

Save a time-stamped history documenting all processing and edits made to a file from the time it was opened. This feature is invaluable for archiving and forensic work.

Azimuth Alignment

Both automatic and manual azimuth alignment are available for correcting misaligned tape heads in tape restoration.
