CEDAR Audio Declick for Pro Tools

The Problem:

Scratches and clicks are encountered on all audio media - film, tape or disk, whether analogue or digital - so CEDAR's processes are invaluable when dealing with master tapes, film soundtracks, videos, interview and surveillance tapes, and vintage recordings.

The Solution:

Incorporating both manual and auto declick capabilities, CEDAR Tools Declick comprises two AudioSuite processes that perform at high speed without sacrificing CEDAR quality.  The two together ensure that Declick addresses the widest possible range of scratch and click removal problems.

Auto Declick:

Allows the user to process part or all of an audio region as an off-line process.  Remarkably, there is no need for controls because the algorithm detects each click, removes it, and then fills the gap with the best estimate of the material that existed (or would have existed) had the click not occurred.  The maximum click length handled is 100 samples at 44.1kHz, or 200 samples at 96kHz. 

Manual Declick:

Is ideal for restoring audio that suffers from problems for which auto declick is not ideal.  It allows users to specify the audio that constitutes the unwanted noise, and the algorithm - optimised for extended clicks and scratches - will eliminate noises such as those found on optical soundtracks, as well as drop-outs and extended digital errors.  

The maximum click length handled is 2,048 samples at 44.1kHz, or 4,096 samples at 96kHz.
