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.
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. Mar 06, 2015 For a refresher on RX 4 Advanced’s legacy features, check out my review of RX3 Advanced in the May 2014, issue of Mix. Streamlined Interoperability. RX’s Spectral Repair plug-in—which was a bit of a kludge in previous releases—has been discontinued, made obsolete by the new RX Connect plug-in and alternative DAW interoperability. The Spectral De-noise plug-in and module in iZotope RX 7 provides natural noise reduction with unparalleled clarity and control. Built with the most troublesome audio imperfections in mind, Spectral De-noise removes unwanted tonal and broadband noise from any type of recording—such as music, old recordings, home movies, production recordings, and more. Spectral Repair Spectral Repair in iZotope RX 7 is the key to discovering what your waveform won't show you. Use familiar drawing tools to identify and select problem frequencies and unwanted sounds. Salvage unusable material by filling in audio gaps instantly. Here are some key features of iZotope RX Advanced Audio Editor: – a complete standalone application and suite of plug-ins designed for audio restoration – suppress broadband and tonal noise without the harsh artifacts of other solutions – remove intermittent noise, corrupt intervals and gaps with Spectral Repair re-synthesis.
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
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.
Spectral Repair Controls:
Number of bands - selects the number of frequency bands used for interpolation. A higher number of bands can provide better frequency resolution, but also requires wider surrounding area to be analyzed for interpolation.
Direction - In Attenuate mode, Direction determines whether material to the left and right (Horizontal), above and below (Vertical), or both horizontal and vertical (2d) is used in repairing the selection.
Strength - parameter adjusts strength of attenuation in Attenuate mode.
Surrounding region length - defines how much of the surrounding content will be used for interpolation
Before/after weighting - gives more weight to the surrounding audio before or after the selection
Harmonics sensitivity - adjusts amount of detected and linked harmonics in Partials + Noise mode. Lower values will detect fewer harmonics, while higher values will detect more harmonics and can introduce some unnatural pitch modulations in the interpolated result.
Search Range- in Spectral Repair Pattern mode, selects the length of the audio segment used in a search for a suitable replacement interval. For example, setting it to 5 seconds will allow search within +/-5 second range from the selection.
Depending on the mode and settings, Spectral Repair will have varying limits to the amount of audio that can be processed in your selection.
Unlimited - Attenuate when in Vertical mode
10 seconds - Attenuate Horizontal or 2D, Replace modes;
4 seconds - Pattern, Partials+Noise modes.
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.

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.
