CEDAR Cambridge adds more forensic tricks to its arsenal
Published: PRODUCTS

The latest round of updates for CEDAR Audio’s Cambridge line has seen Cambridge V11 gain several new forensic audio tools – audio enhancement, dialogue noise suppression and restorations modules –joining the existing suite of more than 30 audio tools. According to CEDAR, these have been presented with simplicity of operation and speed of use in mind, offering Learn and Auto functions where possible to determine the optimum processing parameters. A derivation of the manufacturer’s CEDAR Trinity surveillance systems typically supplied to law enforcement agencies has also been released for audio forensic use in Cambridge. It is stated to provide four related tools that, through the use of four sliders, allow users to suppress background noise, reveal voices and increase the intelligibility of speech. It also allows user to enhance the background if that contains wanted detail. Once again ease of use is the focus with Cambridge Trinity Enhance, as the manufacturer claims that even a noise can clean up difficult material to a standard that would have seemed impossible a few years ago.
Finally, the Declip tool present in Cambridge V10 has been replaced with Declip-2, based on an improved algorithm. As with the previous version, the process looks to identify and remove most instances of clipping in a single real-time pass, however a new adaptive Auto mode which identifies the clipping point and tracks changes in the amplitude at which clipping occurs, aims to eliminate distortion and restore the original dynamic range of the signal with a single-button press. Manual controls are also supplied for tweaking the results if desired.
Cambridge V11 will be shipped with CEDAR’s Cambridge Series IV host systems running Windows 10 Pro 64-bit. It will reportedly run successfully on all previous Series IV hosts as well as CEDAR Cambridge Series III hardware (with a new video card) running Windows 10 Pro 64-bit or Windows 7 Ultimate Pro. Some earlier systems may also support Cambridge v11, but the manufacturer stresses that performance will be compromised and some features and modules will not be available.
