Eliminating even the largest and most extended clicks
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 maximum click length handled by Manual Declick is huge: 2,048 samples at 44.1kHz, or 4,096 samples at 96kHz. This makes it ideal for restoring audio that suffers from problems for which streamed processes are less than 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. Two processing modes are available:
Manual Declick A
The general purpose manual declicker; the optimal choice for many situations.
Manual Declick B
Removing extended clicks in the presence of high levels of background noise can lead to a hole in the background even though the music or speech signal is reconstructed correctly. The Manual Declick B algorithm maintains the atmos, even when restoring the longest and most intractable clicks and other impulses.
