Cutting-edge Processing Algorithms

Leveraging iZotopes extensive research and development expertise, RX 2 features a complete set of the best tools for repairing audio. The Denoiser provides 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 Global 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 its output. The end result is cleaner audio in less time.



Visual Editing

RX has defined a new, intuitive visual editing paradigm allowing you to use both your eyes and ears to identify sonic problems. The unmatched precision of RXs spectrogram audio display illuminates sounds ranging from subtle distortions, to clicks and pops, to complex interferences like car horns, airplanes, and wrong notes. Once you can see the sound, the Lasso and Brush tools allow you to do freehand selections of the sounds for repair. Going further, the Magic Wand will even automatically identify a sound and its harmonics.


Spectral Repair

For transparently masking problems or filling in gaps, Spectral Repair is at the heart of the visual editing engine in RX. Once a problem sound has been identified 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.


Optimized Workflow

RX was designed from the ground up specifically for audio restoration and repair. Careful thought has gone into every display and keyboard option to enable you to work quickly and reliably. The Compare Settings feature lets you audition multiple settings of the same module and then audition the results side by side. A comprehensive history of session edits lets you undo any edit and compare different processing passes to decide which you prefer. If youre working with large numbers of files, the new batch processor streamlines your work even further by letting you chain together selected processing modules and process entire folders at once, all while taking advantage of multicore CPUs to speed up the process.


Declick & Decrackle

The Declick module has been simplified and expanded with the newly added Decrackle module, designed to treat continuous background crackle from vinyl and similar sources. The Declick module can automatically suppress clicks and pops as well as similar digital impulse noises, and in some cases, can even be used to remove the annoying beeps introduced by cell phones during recording.


Session Support

Save your editing session when quitting and pick up where you left off the next time the app is started. 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.



Precise Delay and Phase Operations

New Channel Operations module features sub-sample delay and arbitrary phase rotation operations. Both features are crucial when restoring audio which was transferred from tape.
