The Problem

Extended scratches and clicks are encountered on many audio media - film, tape or disk, whether analogue or digital. It may not be possible to restore these using CEDAR's real-time declickers because the disturbances are too long for the algorithms to handle.

The Solution

Manual Declick is ideal for restoring audio that suffers from problems for which Declickle 2 is not ideal. It allows users to specify the audio that constitutes the unwanted noise, and the algorithm - optimised for long clicks and scratches - will remove noises such as those found on optical soundtracks, as well as drop-outs and extended digital errors. Simply mark the offending signal, and Manual Declick will eliminate the problem.

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