Why Upgrade?
RX 2 features several new algorithms and workflow changes equipped to cover even the most challenging repair tasks.
RX 2 Advanced Highlights
- Adaptive mode in Denoiser to remove noise that changes over time
- Deconstruct, a new class of audio manipulation for control over noisy and tonal components of sound
- 3rd party plug-in support enabling any processing on spectrogram selections and in Compare and Batch Processing features
- iZotope 64-bit SRC™ for sample rate conversion, MBIT+™ for dithering and iZotope Radius® for changing time and pitch
- Time-stamped log creation, essential for forensics and archival documentation
- Spectral Repair multi-resolution mode for more accurate separation of noise and desired content
- Automatic Azimuth alignment and precise sub-sample control of delay for tape restoration
Added and Improved Processing
- Denoiser features new Global Smoothing control and high frequency enhancement for increased transparency
- Declick features improved click detection and new Decrackle algorithm designed to treat continuous background crackle from vinyl and older media
- New channel operations left/right channel mixing and arbitrary phase rotation
- Spectral Repair now allows longer and unlimited selection processing
- Gain module has new advanced fade methods
Enhanced Visual Editing
- New Lasso, Brush and Magic Wand tools allow natural, freehand selections around problem sounds, so you're no longer constrained by a selection box
- Magic Wand can automatically select a sound and its harmonics for incredibly fast editing
- Make multiple selections and process them all together, saving time as you audition different options
- Ability to hide side and bottom panels provides a nearly full-screen view of your audio spectrogram or waveform
Optimized Workflow
- 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. Get back up and running immediately.
- Updated batch processor allows you to chain together multiple modules and process multiple files at once, using multiple CPUs for full optimization
- Remove Hum now intelligently identifies the hum frequency for quick suppression
- And many other small keyboard, mouse and UI improvements
Deconstruct Module - New Creative Control
With RX 2 Advanced, iZotope is introducing a new class of audio manipulation tool. Deconstruct intelligently separates audio into tonal and noisy components. For example, a singer's voice has tonal parts (vowels, M and N sounds) and noisy sounds (breath sounds and sibilance like H, S and Sh). Advanced gives you the power to separate and rebalance these audio building blocks, opening up creative possibilities like accentuating only the tonal parts of a flute or sax recording, or bringing out the airy qualities of a nuanced vocal performance.
New Feature Highlights
RX 2 | RX 2 Advanced
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 2 | RX 2 Advanced
Adaptive Denoiser Mode
Denoise now features an adaptive mode to automatically adapt to a changing noise profile, especially important for video-post and others who deal with dynamic background noise.
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.
iZotope 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.
