Repair Assistant

Overview

Repair Assistant is designed to detect common audio problems in a recording and quickly provide suggested settings for improving them. The Repair Assistant interface provides access to parameters that allow the user to fine-tune the suggestions to their own liking. Repair Assistant is available in the RX Audio Editor as a module and as a plug-in.

Repair Assistant Module

To open Repair Assistant in the RX Audio Editor application, simply click the Repair Assistant button in the upper right-hand corner of the RX Audio Editor window.

After opening the module, choose between Voice and Music modes. This changes the type of processing chains generated and is used in analysis to measure noise amounts and determine processing components and settings. Voice mode is intended for spoken word or dialogue. Music mode is intended for a full-mix music recording, individual instruments, or isolated sung vocals.

Next, click Learn to analyze your audio. Repair Assistant is designed to be trained on audio that contains dialogue, vocals, music, and sound effects. It isn’t necessary to learn on noise-only segments of audio like with other modules such as Spectral De-noise. Repair Assistant analyzes any selection made in the Spectrogram (if no selection is made it analyzes as much data as necessary in order to make an effective suggestion) and automatically adjusts the settings for optimal repair of your audio. After analysis is complete, you will be able to adjust the various parameters of the tools that are working inside the assistant.

To apply Repair Assistant’s recommended processing to the current selection, select the processing option in the Repair Assistant window and click the Render button in the bottom right-hand corner of the window.

The Open Module Chain allows you to save Repair Assistant’s recommendations as a Module Chain preset, or make changes to the generated settings before rendering. To open Repair Assistant’s recommendations in the Module Chain, click the Open Module Chain button in the Repair Assistant footer area (this feature is available in RX 11 Advanced only).

Repair Assistant Plug-in

The experience in the Repair Assistant Plug-in is very similar to that of the Audio Editor, but the plug-in analyzes your audio as you play audio, as opposed to analyzing the entire file/selection. To use the plug-in, simply choose your Mode (Voice or Music), click Learn, and play your track. Keep playing until Repair Assistant has finished listening to your audio and created its suggestion.

Note

When using AudioSuite, clips must be longer than 7 seconds. Learning a clip less than 7 seconds long will cause the plug-in to 'learn' indefinitely and appear to hang in this state. When using AAX, you may loop shorter clips in order to run learning.

Voice Mode

Common Controls

  • The On/Off button in the upper left corner of each section enables/bypasses that section.

  • The Audition button in the upper right corner of each section allows you to hear only what is being removed by that section.

    ear blue

Clean Up

  • De-noise: Controls the applied amount of Dialogue Isolation processing.

  • De-reverb: Controls the applied amount of De-reverb processing.

  • De-hum (on/off): Activates/deactivates De-hum processing (De-hum will only operate if hum is detected during learning).

  • De-click (on/off): Activates/deactivates De-click processing.

Tone

  • %: Controls the amount of boosting/cutting bi-directionally (based on EQ shape).

  • % (Tilt): Positive boosts the high end and lowers the low end; Negative boosts the low end and lowers the high end.

  • % (Scoop): Positive boosts the high end, boosts the low end, and lowers the mid range; Negative lowers the high end, lowers the low end, and keeps the mid range as-is.

  • Tilt/Scoop: Choose which EQ shape to use.

  • Lo-cut (on/off): Activates/deactivates lo-cut filter.

  • Hi-cut (on/off): Activates/deactivates hi-cut filter.

De-Ess

  • Shaping: Determines how much the spectral shape of the sibilant is changed.

    • A setting of 0% leaves the natural shape of the sibilance.

    • A setting of 100% flattens the shape of the sibilant toward a specified spectral profile.

  • Threshold: Determines the level at which the De-ess module begins compressing sibilance.

  • Fast/Slow: Sets the attack and release times for the processing.

De-Clip

  • Threshold: Defines the level used for detection of clipped intervals. Generally, this should be set just below the actual level of clipping. To set the threshold, move the Threshold slider until it lines up with the place in the histogram just below where clipping is concentrated.

  • Output Gain: Selects the gain to be applied to the selection after De-clip.

  • Limiter (on/off): Applies a true peak limiter after processing to prevent the processed signal from exceeding 0 dBFS.

Music Mode

Common Controls

  • The On/Off button in the upper left corner of each section enables/bypasses that section.

  • The Audition button in the upper right corner of each section allows you to hear only what is being removed by that section.

Clean Up

  • De-noise: Controls the applied amount of Adaptive De-noising (best for eliminating room tone in vocals or mic’d acoustic instrument recordings).

  • De-squeak: Controls the amount of processing for removing fret and finger noises/squeaks that occur when sliding up or down the guitar neck between notes or chords.

  • De-hum (on/off): Activates/deactivates De-hum processing (De-hum will only operate if hum is detected during Learning).

  • De-Pick (on/off): Activates/deactivates De-pick processing

Tone

  • % (Tilt): Positive boosts the high end and lowers the low end; Negative boosts the low end and lowers the high end.

  • % (Scoop): Positive boosts the high end, boosts the low end, and lowers the mid range; Negative lowers the high end, lowers the low end, and keeps the mid range as-is.

  • Tilt/Scoop: Choose which EQ shape to use.

  • Lo-cut (on/off): Activates/deactivates lo-cut filter.

  • Hi-cut (on/off): Activates/deactivates hi-cut filter.

De-Harsh

  • Cutoff: Specifies the crossover point between musical signal (to be preserved) and “harshness” (to be reduced). The Cutoff frequency value functions as the lower boundary for harshness detection.

  • Threshold: Determines the level at which the De-harsh module begins compressing harshness.

  • Fast/Slow: Sets the attack and release times for the processing.

De-Clip

  • Threshold: Defines the level used for detection of clipped intervals. Generally, this should be set just below the actual level of clipping. To set the threshold, move the Threshold slider until it lines up with the place in the histogram just below where clipping is concentrated.

  • Output Gain: Selects the gain to be applied to the selection after De-clip.

  • Limiter (on/off): Applies a true peak limiter after processing to prevent the processed signal from exceeding 0 dBFS.

Repair Assistant Preferences

To bypass analysis by any of the Repair Assistant modules, click on the gear button in the upper right-hand corner of the Repair Assistant window to open the Assistant Preferences. All modules are selected by default, and deselecting any module will remove it from Repair Assistant’s analysis.

These preferences apply only to Repair Assistant in the RX 11 Audio Editor application, not the plug-in. For more information about the RX Preferences menu, see the Preferences chapter.
