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 96kHz. 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.
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. It also hosts three off-line processes - Manual Declick, Dethump and Retouch 4™ - helping to make even the most intractable of problems quick and simple to rectify. To aid this, CEDAR Cambridge v4 and onwards has Time Markers that allow you to identify and move to audio events at the touch of a key.
The Timecode Automation Controller
The dedicated timecode reader/generator ensures that processed audio always remains aligned to video, so that all CEDAR Cambridge Forensic Systems will work in harmony with other audio or video surveillance. It also provides facilities for full automation of all the forensic systems' processing parameters.
Audio Modules - version 2
There are five dedicated CEDAR Cambridge forensic processing modules. All offer advanced graphic tools, visual feedback, and save/recall capabilities that allow you to save your settings and recall them for future reference.
CEDAR Forensic Systems allow you to launch and manipulate multiple processes simultaneously, either applying multiple analysers and filters to each signal, or applying individual processes to each channel. This is particularly useful when using the full Forensic System, where you may apply multiple noise reduction systems, adaptive filters, declickers, debuzzers, declippers, EQs and analysers in a single real-time pass.
Why "version 2" ?
Version 2 of CEDAR’s Adaptive Filter Pack represents a significant upgrade on previous systems. Introducing CEDAR’s proprietary “Out Of Band” capability, these filters allow users to retain much more of the energy associated with sibilants and fricatives to maximise the intelligibility of the speech. This makes CEDAR’s adaptive filters far more effective than those that analyse and filter the whole signal in a single frequency band.
The Adaptive Filter Pack v2 is a free upgrade for all existing owners of the Adaptive Filter Pack, and is fully compatible with all versions of CEDAR Cambridge hardware.
