Spectral repair is a tool for interpolating selected areas on a time-frequency spectrogram. It is able to provide higher quality than the Declicker tool for long corrupted segments of audio (above 10 ms). Spectral repair can be used to remove (or attenuate) certain unwanted sounds from recordings, such as squeaked chairs, coughs, dropped objects, mobile phone calls, etc.
Attenuate: this mode can be used when the corrupted interval contains sufficient useful information. This method reduces spectrogram magnitudes in the selected area to match magnitudes from the surrounding area.
Replace: this mode completely replaces the selected content with a content interpolated from the surrounding data. The number of frequency bands used for interpolation is selectable. RX

Oct 03, 2016 Certainly don't use Spectral Repair for getting rid of hiss. There is a trick using Denoise: in spectral view, having selected the offending part of the spectrum using lasso or brush, make it 'learn', and it will use only this selection as noise footprint. Apr 20, 2017 Published on Apr 20, 2017 RX 6 includes Spectral Repair allowing you to surgically remove noise issues that can ruin an otherwise flawless performance. Instantly paint away recording issues like.
Pattern: this mode finds the most similar portion of the surrounding audio and uses this to replace the corrupted audio.
Partials + Noise: this mode allows for higher-quality interpolation by explicit location of signal harmonics from 2 sides of the corrupted interval and linking them together by synthesis. This method is able to correctly interpolate cases of pitch modulation, including vibrato. The rest of non-harmonic material ('residual') is interpolated using Replace method.

Processing Limitations
Depending on the mode and settings, Spectral Repair will have varying limits to the amount of audio that can be processed in your selection.

Surrounding Region Shading
When using the Spectral Repair module, your selections will be shown with a dotted line surrounding your selected region. This dotted line is directly controlled by the Surrounding Region and Before/After Weighting controls inside of your Spectral Repair modules, and provides a visual representation of your set values.
The surrounding region is the region that RX uses for interpolation of the selected region. The data from the surrounding region is used to restore the selected region.

Multi-Resolution
The Multi-resolution mode enables multi-resolution mode when better frequency resolution is used for interpolation of low-frequency content and better time resolution is used for interpolation of high-frequency content.
The Multi-Resolution processing options is available for each of the Spectral Repair modes individually.
In addition to the base version of RX 2, an extended application, iZotope RX 2 Advanced, offers even more precise control over RX 2 algorithms as well as including iZotope's critically acclaimed 64-bit SRC sample rate conversion and MBIT+ dither for professionals who want finer control over processing and delivery.
