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.

Features:

Denoise

Reduces broadband and tonal noise transparently with natural results. RX Advanced now includes adaptive mode.

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

Isolates and eliminates unwanted sounds visually, even when buried in complex noise and harmonic material.

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

Separate audio into tonal and noisy components for independent control.

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

Rebuilds distorted audio damaged by analog and digital overloads.

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.

Declick & Decrackle

Eliminates clicks, crackles, pops and digital impulse noises.

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

Cleans up electrical hum and line noise including harmonics.

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

Wordlength reduction featuring psychoacoustic noise shaping.

iZotope 64-bit SRC™

Hybrid linear and minimum phase sample rate conversion algorithm.

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.

Spectrum Analyzer

High-precision spectral display featuring automatic peak finding.

3rd Party Plug-ins

Host any DirectX, Audio Unit and VST plug-ins using spectral selection, Batch Processor and Compare feature.

Batch Processing

Chain modules, process multiple files and use multiple CPUs to optimize workflow.
