"The results are most fascinating. You can´t help but exploit the creative uses for this package, which go way past the obvious practical roles that it fulfils so excellently." - Computer Music
“With RX 2, iZotope has made an already excellent piece of software even better. It’s a superb standalone/plug-in audio restoration suite that offers incredible value for money.” - Music Tech
Please note that this product description also describes the additional features found in the RX2 Advanced version
iZotope RX™ 2 is the most complete audio repair toolkit on the market, enabling you to remove noise, hiss, buzz and hum, eliminate clicks and crackle, restore clipped audio, visually select and suppress unwanted sounds, resynthesize missing audio and much more.
RX 2 Advanced extends this standard version of RX 2 with new, specialized tools designed for audio professionals.
A Complete Set of Tools
RX includes all of the tools you need to repair both common and uncommon problems:
RX 2 Advanced adds an Adaptive Denoise mode, Deconstruct and Azimuth Alignment.
Channel and Phase Operations, Spectrum Analyzer, EQ, gain fades and more.
RX 2 Advanced also features iZotope 64-bit SRC™ for sample rate conversion, MBIT+™ for dithering, and iZotope Radius® for changing time and pitch.
Visual Editing
RX has defined an innovative visual editing paradigm allowing you to use both your eyes and ears to identify and fix sonic problems:
Rich spectrogram display visualizes the audio in an incredibly intuitive and precise way.
New Lasso, Brush and Magic Wand tools allow natural freehand selections around problem sounds.
Spectral Repair resynthesizes audio allowing you to seamlessly remove unwanted individual sounds or even fill gaps in your recording.
Optimized Workflow
RX was designed from the ground up specifically for audio restoration and repair:
Includes a standalone application and a suite of plug-ins for your DAW to fit the way you want to work.
Edit History tracks every change allowing you to undo and compare processing.
Compare Settings lets you process and audition multiple settings side by side.
Application session state saved even between restarts.
Batch processor can process tons of files quickly with any combination of modules.
Features
Denoise
Leveraging iZotope´s extensive research and development expertise, the Denoise module and Denoiser plug-in provide natural noise reduction with unparalleled clarity and control. Using psychoacoustic principles and high frequency resynthesis, the noise suppression takes on a new level of transparency. With methods drawn from the science of image noise reduction and a new hybrid time/frequency Smoothing algorithm enhancement, the distracting watery artifacts commonly associated with noise suppressors are inaudible. The Denoiser allows independent control over both the tonal and broadband components of noise, providing ultimate creative control over the color of the end result.
RX Advanced even features a mode for removing noise with a dynamic spectral profile with the new Adaptive mode, which automatically compensates for changes in background noise. The end result is cleaner audio in less time.
Spectral Repair
For transparently repairing problems or filling in gaps, Spectral Repair is at the heart of the visual editing engine in RX. Once a problem sound has been indentified and selected, the Spectral Repair algorithms are able to resynthesize the audio while taking into consideration tonal harmonics, nonlinear pitch changes like vibrato, background noise characteristics and transient events. With the power of these tools, you can remove unwanted, interfering sounds ranging from dogs barking to string squeaks and missed notes.
RX Advanced additionally features a multi-resolution mode for more accurate separation of noise and desired content.
Deconstruct
With RX 2 Advanced, iZotope is introducing a new class of audio manipulation tool called Deconstruct. 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).
RX 2 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.
Declip
The Declip module and Declipper plug-in reconstruct peaks damaged by clipping at either the analog or digital stage. Use the level histogram to pinpoint where the damage starts. Set the Clipping threshold to set where peak resynthesis will begin.
Declip and Decrackle
The Declick module and Declicker plug-in automatically identify clicks, pops and digital impulse noises and remove them seamlessly. For the best performance, select from one of several algorithms for periodic or random clicks. Additionally, the application´s Interpolate mode allows you to make manual sample-level corrections to audio.
The newly added Decrackle mode and Decrackler plug-in are designed to treat continuous background crackle from vinyl and similar sources.
Remove Hum
Automatically identify the base frequency of hum for precise removal of the fundamental and harmonics. The module will even recommend when Denoise should be used to more effectively treat certain kinds of hum.
MBIT+ dither
iZotope´s MBIT+™ dithering algorithm features psychoacoustic noise shaping, based on research with actual musical material, making it the best sounding dither on the market.
iZotope 64-bit SRC
The iZotope 64-bit SRC™ utilizes a hyrbrid algorithm providing the highest quality and most customizable resampling available on the market today.
Radius Time Pitch
iZotope´s world class time-stretching and pitch-shifting algorithm.
Gain
The Gain module now includes support for fades with several fade types.
EQ
6-band parametric equalizer module with adjustable notch filters and low pass/high pass filters.
Channel Operations
Precise delay and phase operations. Advanced now includes Azimuth alignment.
