CEDAR has led the world in audio restoration since the 1980s, introducing features and capabilities that many stated were impossible before we did them. Real-time digital declicking and decrackling? A CEDAR 'first'. Digital noise reduction with a fingerprint? Also invented by CEDAR. Noise-free equalisation? Sub-sample phase/time correction? Spectral editing? All of these were researched and developed first by CEDAR. Today, we have combined eight of our favourite processes into a single package: CEDAR Studio Restore. This allows you remove a huge number of the problems that you'll encounter, whether transferring from old and damaged media, cleaning up soundtracks for film and TV, restoring material for broadcast. and much more.
Eliminate clicks with the minimum of fuss
Declick offers better impulsive noise detection and a better interpolator than any other plug-in declicker. This results in superior performance across a wider range of material than ever before. Indeed, this performance is so good that, in most cases, it's not possible to hear that the signal was damaged prior to restoration.
Dig deeper to eliminate crackle and other problems
Decrackle boasts a remarkable ability to dig into the damaged signal to identify and remove all manner of ground-in and grungy crackle without damaging the wanted audio. It also removes many forms of buzz and some amplitude distortions from material ranging from cylinder recordings to current broadcasts contaminated with lighting buzz.
Remove extended clicks and scratches (Pro Tools only)
Extended scratches and clicks are encountered on many audio media - film, tape or disk, whether analogue or digital. Manual Declick is ideal for restoring these, and its unique dual algorithms - 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.
Removing bumps and thumps (Pro Tools only)
Conventional declicking processes and filters are unsuitable for restoring audio containing extended low-frequency thumps. Dethump eliminates these, replacing the unwanted sound with restored low frequency audio and is the ideal tool for removing many of the previously intractible problems associated with optical soundtracks, cylinders, discs, and even cleaning modern recordings when, for example, microphones and stands are bumped.
Automatic dehissing that really works
Other plug-in dehissers are prone to side-effects, often called twittering and glugging. Auto Dehiss embodies a far more advanced algorithm that enables the software to determine the broadband noise content and remove it without the introduction of these unwanted side-effects or artefacts. A manual mode is also offered for fine-tuning the results when wanted.
Eliminate buzz and hum
Buzzes and hums can creep into the highest quality recordings and live audio, but can be eliminated quickly and easily using Debuzz. This is capable of removing all manner of buzzes and hums with fundamentals as high as 500Hz and can eliminate unwanted signal components across the entire audio spectrum. Debuzz will track wandering tones and, unlike traditional filters, can successfully restore the audio without unwanted side-effects such as limited bandwidth or the hollow sound introduced by comb filters.
Reconstruct clipped audio
You'll be amazed at how effortlessly Declip 2 removes clipped samples and reconstructs the original signal, improving clarity, eliminating distortion, and restoring the original dynamic range of the damaged audio. Unique to Declip 2, this latest algorithm even tracks the clipping amplitude so that material that has later been processed with dynamics packages can still be restored.
Finish your audio using a unique limiter
The Adaptive Limiter employs another unique algorithm developed by CEDAR that calculates a continuously varying EQ profile that constrains the peak level of the output while retaining the integrity of the input. The result is a perfectly controlled signal that remains much more natural than audio processed using other limiters. It is also an unsurpassed loudness maximiser and, with its advanced resampling and noise shaping capabilities, is ideal for mixing, final mastering and other creative duties.
