A new suite of processes for Merging Technologies' 64-bit Pyramix systems, CEDAR for Pyramix 64™ comprises advanced processes that allow you to eliminate a wide range of common problems and significantly improve the sound quality of your audio. Each CEDAR for Pyramix 64 process has been derived from our multi-award-winning CEDAR Studio 7™ and CEDAR Cambridge™ flagships, and provides unsurpassed results, quickly, and with the minimum of fuss and user intervention.

CEDAR for Pyramix 64: Auto declick

Seamlessly eliminating clicks with the minimum of fuss

With both manual- and auto- declicking capabilities, CEDAR for Pyramix 64 performs at high speed without sacrificing CEDAR quality, and addresses the widest possible range of scratch and click removal problems.

Auto declick (which now offers a threshold control for greater flexibility) incorporates a better impulsive noise detection and a better interpolator than any previous declicker available for Pyramix. 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.

CEDAR for Pyramix 64: Auto decrackle

Digging deeper to eliminating crackle and other problems

Based upon the technology that underpinned the renowned CEDAR CR-1, Auto decrackle boasts a remarkable ability to dig into a damaged signal to identify and remove all manner of ground-in and grungy crackle without damaging the wanted audio. It also removes some forms of buzz and some amplitude distortions from material ranging from cylinder recordings to current broadcasts contaminated with lighting buzz.

Now offering a threshold control for greater flexibility, it's amazingly simple to operate and as applicable to film soundtrack restoration, audio forensics and broadcast as it is to traditional audio restoration jobs such as CD and DVD remastering.

CEDAR for Pyramix 64: Auto dehiss

Automatic dehissing that really works

Many plug-in dehissers are prone to side-effects known as twittering and glugging. Auto dehiss embodies a more advanced algorithm that enables the software to determine the broadband noise content and remove it without the introduction of those artefacts or other unwanted side-effects. A manual mode is also offered for fine-tuning the results when wanted.

Remarkably simple to use, Auto dehiss is nonetheless a fully-featured package for cleaning up audio for post, CD and DVD mastering, soundtrack restoration, broadcast, and sound archives.

CEDAR for Pyramix 64: Manual declick

Seamlessly eliminating larger and longer clicks with the minimum of fuss

With both manual- and auto- declicking capabilities, CEDAR for Pyramix 64 performs at high speed without sacrificing CEDAR quality, and addresses the widest possible range of scratch and click removal problems.

Manual declick incorporates a new algorithm capable of restoring clicks and other problems - such as drop-outs and digital errors - of up to 2,000 samples duration. It allows users to specify the audio that constitutes the unwanted noise, and its 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.

To extend its flexibility and ensure effective restoration in the widest possible range of cases, two declick models are provided:

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. CEDAR's Manual Declick 'B' algorithm retains the atmos, even when restoring the longest and most intractable clicks and other impulses.

CEDAR for Pyramix 64: Dethump

Restoring low frequency thumps of up to 100,000 samples duration

Thumps may last for many hundreds of milliseconds, so conventional declicking processes are unsuitable for restoring audio containing them. Furthermore, the spectral content of thumps will usually overlap the genuine signal, so simple high-pass or band-reject filters cannot remove them without degrading the underlying signal.

Dethump uses the data in and around the damaged signal to build up a picture of what the low frequency data should have been had the thump not occurred. The process then replaces the thump with restored low frequency audio, leaving the undamaged high frequency audio unaffected. This makes dethump ideal for removing many of the previously intractable problems associated with optical soundtracks, as well as for restoring damaged cylinders and discs, and for cleaning modern recordings when, for example, microphones and stands are bumped. No other process can analyse and restore damaged signal of up to 100,000 samples duration.

Continuity

The six processes in CEDAR for Pyramix 64 significantly extend the capabilities of the original CEDAR for Pyramix suite but retain the family 'feel' so that existing users are immediately comfortable and productive with the new software.
