The De-click plug-in is useful for repairing clicks and glitches (short impulse noises) from a wide variety of material, including digital errors, mouth noises, mistaken drumstick hit, interference from cell phones, or any other audio problem caused by impulses and discontinuities in a waveform.
The De-click plug-in’s sophisticated algorithm analyzes audio for amplitude irregularities and smoothes them out. Here’s a recording with clicks before, and after click removal:
Algorithm
Controls the interpolation processing quality and configuration depending on the type of clicks and pops in the audio.
- Single-band: processes quickly and works well on very narrow “digital" clicks
- M-band (periodic clicks): multiband processing for removing regularly repeating clicks with a wider spectrum, or regular clicks that have concentrated low or high energy (like thumps or optical soundtrack perforation noise)
- M-band (random clicks): multiband processing for wider vinyl clicks and thumps, with a protective algorithm for preserving periodic audio elements characteristic to certain instruments such as brass or vocals
Click Type
Changes the De-clicker controls to address specific kinds of clicks.
- Click: the default setting of De-clicker. Optimized to handle most clicks
- Thump: skews the click detector frequency response toward lower frequencies to tackle thumps
- Discontinuity: widens the click processing range to smooth out clicks caused by waveforms that change suddenly in amplitude
Sensitivity
Controls the sensitivity of the click detector.
Low values of this parameter will remove fewer clicks, while higher values can repair too many intervals which can result in distortion.
Clicks only
Outputs the difference between the original and processed signals (suppressed clicks).
