DeClick Plus uses a sophisticated algorithm designed to simultaneously track time-varying characteristics of a processed audio signal, isolate and reconstruct irrevocably distorted samples, e.g. samples corrupted with clicks, pops, record scratches and other forms of impulsive noise.
DART XP Pro allows you to overrule decisions made by the outlier detector - a special device designed to localize impulsive disturbances due to clicks, pops and record scratches. You can set, remove or modify detection alarms by editing detection files <*.det>. When operated in the ReTouch mode, the system does not use the internal outlier detector - it reads and interprets the contents of the corresponding detection file instead.
The ReTouch option can be used for the purpose of perfecting the restored soundfiles, e.g. to remove noise pulses overlooked by the system or to preserve without changes some genuine signal features misclassified as outliers.
