The AAIB is responsible for the investigation of civil aircraft accidents and serious incidents within the UK, and now uses a CEDAR Cambridge forensic system to assist with the analysis of communications recorded by Cockpit Voice Recorders (CVRs).
AAIB Senior Inspector Peter Wivell states, "Cleaning noisy recordings is not a constant task for us, so a complicated system would not be viable at the AAIB. The simple controls of CEDAR backed by powerful processing mean that we get instant audible feedback on the effects of the tools, allowing us to find quick solutions to problems."
He continues with the following example, "Air traffic control is often mixed with the crew voices on the recordings at a volume that obscures pilot discussions. CEDAR Retouch allows us to remove cockpit alerts and other noises, allowing further recovery of potentially significant spoken words."
Modern audio delivery systems have increased the need for a wider range of audio tools capable of cleaning up everything ranging from recordings made in extreme environments to contemporary Hollywood blockbusters. CEDAR Cambridge gives its users the power to address all of the noise problems they might encounter. It offers a wide range of restoration, speech enhancement and audio sweetening tools applicable to mastering, post, broadcast, archives, libraries, and audio forensic investigation.
