The science of eliminating coughs, scuffs, page turns, creaky piano pedals, and even car horns

CT13: Retouch

The Problem

Until now, audio restoration systems have been limited as to the types of noises that they can remove: clicks and scratches, crackle and buzz, pops and thumps. But today, CEDAR Retouch offers a huge leap forward in processing technology, allowing you to identify and eliminate sounds as varied as coughs, record scuffs, squeaky chairs, page turns, the creak of a piano pedal, and even a car horn.

There are no conventional methods available for removing these types of noise. Nonetheless, some engineers have attempted to use techniques such as severe EQ which, in addition to being completely inappropriate to such short duration problems, introduces ringing. Retouch does not suffer from this type of side-effect. Others have used (and misused) harsh compression, tight editing, and signal interpolators that affect the whole frequency spectrum. These damage good signal that should be left untouched, and can introduce unwanted side-effects such as drop-outs.

The solution

CEDAR Retouch is a huge leap forward in sound processing technology. Unlike conventional restoration tools, it allows you to define the temporal and spectral content of the sound you want to remove. This makes it possible to identify noises as varied as coughs, squeaky chairs, page turns, the creak of a piano pedal and even car horns. Once identified, unwanted sounds are replaced seamlessly with audio that matches the surrounding signal. All other audio remains untouched.

In photography, 'retouching' is the art of identifying and removing unwanted blemishes from a picture to produce a perfect image. CEDAR Retouch brings this concept into the audio world, allowing you to remove unwanted acoustic events from a signal.

When all else fails... Retouch gives you complete control.
