The File Processor

CEDAR Cambridge audio restoration system, The File Processor

CEDAR Cambridge boasts disk-to-disk and disk-to-world File Processing capabilities that allow users to analyse and process selected parts of, or whole files, rendering the results back to hard disk (disk-to-disk) in a fraction of the time needed to process audio in real-time. Furthermore, you can use the File Processor as a disk-to-world system, passing files through the processing chain and outputting the results so that you can monitor them in real-time.

From V7 onward, CEDAR Cambridge also recognises many new audio formats including MP3 and other Windows Media formats. What's more, it can now handle many video files, allowing users to drag them into its file processor, whereupon a video window window will be opened and the audio will be extracted ready for immediate use.

Recording

The File Processor now hosts a multi-channel audio recorder capable of recording from one to eight channels simultaneously at sample rates of up to 192kHz. You may record over existing audio, append to existing audio, or create new files from incoming audio. It is also possible to record from a external timecode source, with the recorder cursor tracking the incoming timecode and recording audio that is determined by the timecode signal.

Cue points and regions

These allow users to attach text to the audio and to set up multiple regions for rendering, both of which are of huge benefit to users in the film/TV and audio forensic fields. Cue data can be saved in the metadata chunks of WAV files, allowing them to be transferred between CEDAR Cambridge systems and other workstations that recognise those chunks.

Bext Metadata generation and editing

The File Processor now includes a Bext Metadata generator and editor allowing you to create and/or modify existing metadata associated with the audio file.

We have also made the File Processor transparent to existing metadata, both in the BEXT chunk and other chunks, which will pass through the system unharmed if you wish it to do so. And, of course, it's also completely compatible with all existing CEDAR Cambridge processes.

Timecode and timecode generation

CEDAR Cambridge responds to ASIO positioning protocol derived from a suitable audio I/O card as well as to that provided by its own Timecode Automation Controller.

The system outputs timecode in a wide variety of LTC formats when replaying from the File processor. This timecode can be existing timecode attached to a BWAV file, or it can be newly generated by the File processor itself.

Chase Mode

Playback from the File processor can now be sync'd to external timecode, and the system will chase external timecode sources, with vari-speed if required.

Variable speed playback

Existing audio files can be played back at speeds ranging from 10% to 1,000% of the real time, and the resulting audio is always correctly sample-rate converted to produce a high quality audio signal, rather than the grainy or aliased output of some alternatives.

Automation

The File Processor is able to insert, manipulate and respond to automation events, thus allowing you to set up complex event- and scene- based processing, with morphing if required.

Spot processing and track processing

The File Processor hosts spot processes - Manual Declick A & B, Dethump and Retouch 5™ - that help to make even the most intractable of problems quick and simple to rectify. To aid this, CEDAR Cambridge offers Time Markers that allow you to identify and move to audio events at the touch of a key.

In addition to these, a range of track processes provide access to Peak and Power Normalisation as well as the powerful Respeed™ and Reshape™ modules, allowing you to correct replay errors and improve the tonality and soundstage of the material.

Simplicity and productivity

Offering waveform and spectrogram views (or both simultaneously), the clear user-interface provides everything you need on a single screen: intuitive transport controls, variable playback speeds, scrub tool, zooming, sample-accurate looping capabilities, time markers and all the tools needed to process single or multiple audio files quickly and efficiently.
