De-crackle [STD & ADV]

Module & plug-in

Overview

When an audio signal contains many clicks that are close together and low in volume, this is described as crackle. De-crackle is very effective at removing these audio problems and even more effective if it is run after De-click has eliminated the worst offending clicks.

Controls

De-crackle module interface

  • QUALITY:
    • LOW quality offers fast processing
    • MEDIUM quality will remove periodic, rapidly repeating clicks
    • HIGH quality will help preserve the tonal qualities of a signal
  • STRENGTH: Controls the amount of crackle that is detected and repaired.
  • AMPLITUDE SKEW: Biases the processing toward higher or lower volume crackle. If the crackle accompanies transients and other high-level signal passages (such as during clipping), set this control more to the right. If the crackle mostly happens during low-amplitude signal passages, set this control more to the left.
  • OUTPUT CRACKLE ONLY: Outputs the difference between the original and processed signals (suppressed crackle).
