CEDAR Studio Retouch™


CEDAR Studio Retouch


Nowadays, we take spectral editing for granted, but it's a relatively recent invention, first seen in 2002 when CEDAR patented the underlying technology and announced the first version of Retouch. It's not an exaggeration to say that it changed the mastering industry and, today, it's quite likely that you have access to some form of spectral editing that's manufactured under licence from CEDAR.

When it was introduced, Retouch was a huge leap forward in sound processing technology. Unlike conventional restoration tools, it provided a wide range of time/frequency editing (TFE™) capabilities, and allowed you to define the temporal and spectral content of the sound you wanted to remove. Nowadays, it allows you to mark and process complex areas in its spectrogram using the types of tools commonly found in powerful photographic and image manipulation software. This makes it possible to identify all manner of sounds and noises which can then be manipulated using any of the processing tools at your disposal.

Matching

Using machine learning to identify problems...

There are many occasions when you will encounter similar instances of unwanted sounds in a track - things such as hi-hat spill in a multi-track recording, over-excited sibilants and plosives in a vocal track, or even the repetitive noise caused by a piece of machinery in the background. Traditionally, one would remove these sounds by identifying each event individually and then defining it manually prior to processing. But this is time consuming... sometimes very time consuming. So wouldn't it be nice if your spectral repair tool could look at the first instance that you identified and then go on to find all of the others? Well, it can.

Match allows you to mark one of the offending sounds and then ask the machine learning algorithm in Retouch 8 to find all of the other instances within the recording. A threshold control even allows you to bias its decision making toward including more or fewer possibilities so that you can find the level that includes everything that you want to remove but precludes events that seem similar but are actually wanted signal.

Having identified all of the matches, you can then eliminate them using the approporiate Retouch tool. You can process them individually, authorising and applying the chosen tool to each, or you can process all of the matches as a group, whereupon Retouch 8 will fly through the whole file in a tiny fraction of the time needed with human intervention. The increase in productivity is absolutely remarkable.

So why should you choose Retouch? It's because it does the job better than anything else, providing clinical and seamless repair of otherwise intractible problems without leaving behind (or, for that matter, introducing) unwanted artefacts. With its slick user interface and enhanced processing capabilities, Retouch stands alone as the spectral editor of choice for the top mastering studios, mix suites, post houses, forensic laboratories, and anyone else who needs to be able to identify, isolate and manipulate individual sounds within an audio file.

In short...

With its enhanced capabilities, Retouch stands alone as the spectral editor of choice for mastering studios, mix suites, post houses, forensic laboratories, and anyone else who needs to be able to identify, isolate and manipulate individual sounds within an audio file.

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