Timecode Automation Controller
Timecode and automation interface
The Timecode Automation Controller (TAC) is a 1U rackmount unit that integrates CEDAR Cambridge within any studio using SMPTE/LTC timecode, and which adds advanced timecode and automation facilities to the System. It works at all standard frame rates from 24fps to 30fps, and allows you to display all timing information in standard SMPTE format, or in milliseconds, or samples.
For any combination of processing modules loaded at any given time, CEDAR Cambridge calculates the audio signal latency, and you can set the Timecode Automation Controller to use this as a timecode offset, thus ensuring that processed audio always remains aligned to video.
Furthermore, for any sample rate and frame rate, you can round the audio latency up to the nearest complete frame to ensure that CEDAR Cambridge will work in harmony with any audio or video workstation. You may also apply a timecode advance or delay of your choice to compensate for latencies outside CEDAR Cambridge, but which may still affect the synchronisation of the audio and video signals.
The TAC offers both Normal and Chase modes, and works in conjunction with the Event Manager and the File Processor, to allow you to automate all of the processing parameters within Cambridge itself.
The Process Manager
The core of CEDAR Cambridge™
The Process Manager lies at the core of CEDAR Cambridge™ and allows you to invoke a range of tools, setup pages and processing modules. It also reports important information such as the incoming sample rate, the sample resolution and the latency through the entire processing chain, thus allowing you to optimse CEDAR Cambridge™ for most effective use within your studio.
Controlling CEDAR Cambridge™ is easy, thanks to CEDAR's innovative new multi-channel / multi-processor management system. This includes the Channel Selector and Event Manager, as well as all the tools needed to configure the processing and timecode environment to your precise needs.
It could not be easier to apply the process(es) of your choice to each of the channels. Simply select from the list that appears when you click "Insert Module" and that process is available across all the selected channels. You can even change the processing order simply by 'dragging and dropping' a module from one position in the signal path to another
Work the way you want
Select the audio source (incoming audio or the hard disk) and invoke the File Processor to process and monitor WAV, BWF, RF64 and AIFF files in real-time, or to process back to disk at much higher speeds.
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.
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.
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.
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.
CEDAR Cambridge supports multiple languages through the use of internationalisation, which allows experts to localise much of its user-interface. Translation is straightforward, and the resulting language files can be supplied to CEDAR Audio, added to the localisation library and, where appropriate, made available to other users.
