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.

Note: Spectral Repair cannot process selections longer than 4 seconds.

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.

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/virtual-dj-7-4-free-download-with-crack.html. - 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.

  • Multi-resolution -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. (Advanced Only)

  • 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.

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.

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 squeaky chairs, coughs, dropped objects, mobile phones ringing, etc. It can also close up gaps in audio by using advanced resynthesis techniques.

Understanding Spectral Repair Modes

Spectral Repair has several tabs representing different modes of interpolation.

  • Attenuatemode is suitable for recordings with background noise or where noise is the essential part of music (drums, percussion) and should be accurately preserved. It's also good when unwanted events are not obscuring the desired signal completely. For example, this mode can be used to bring noises like door slams or chair squeaks down to a level where they are inaudible and blend into background noise.

  • Replacemode can be used to replace badly damaged sections (such as gaps) in tonal audio.

  • Patternmode is suitable for badly damaged audio with background noise or for audio with repeating parts. It searches surrounding areas for a similar piece of audio and blends it into the selection.

  • Partials+Noisemode is the advanced version of Replace mode. It restores harmonics of the audio more accurately with control over the Harmonic sensitivity parameter. This mode links detected harmonics by synthesizing them through the selection, and interpolates the rest of the signal using the 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.

  • Unlimited - Attenuate when in Vertical mode

  • 10 seconds - Attenuate Horizontal or 2D, Replace modes;

  • 4 seconds - Pattern, Partials+Noise modes.

Applying Spectral Repair

To start working with Spectral Repair, switch to the spectrogram view by dragging the waveform/spectrogram opacity slider to the right. Next, identify the unwanted event on a spectrogram and select it using a time-frequency selection tool (it is not necessary to select a surrounding region, select only the event you want to repair). You can audition this selected time-frequency tile by pressing the 'Play selection' button in the RX transport.

Note: Depending on the mode chosen, Spectral Repair

Note: Some unwanted events consist of several separate regions on a spectrogram. In some cases, it's possible to achieve more accurate results by repairing several smaller selections one by one, instead of one large selection. Also, you can use the Find Similar Event tool to save time when searching for and fixing many similar events in large files.

Once you've found the event(s) to repair, select the appropriate interpolation mode (tab). Sometimes it's worth trying several different methods or number of bands to achieve the desired result. Higher number of bands doesn't necessarily mean higher quality! We encourage you to use the Compare Settings window to experiment and find the best settings for the project at hand.

Common parameters for many methods include 'Surrounding region length' that determines how far around the selection will Spectral Repair look for a good signal. 'Before/after weighting' allows to use more information from either before or after the audio for interpolation. For example, if your unwanted event is just before a transient (such as a drum hit) in the audio, you may want to set this parameter to use more of the audio before the selection to prevent smearing of the transient.
