CEDAR to present forensic audio lecture to the IEE
1 November 2005
On 3rd November, Gordon Reid - Managing Director of CEDAR Audio - will present a tutorial lecture to member of the IEE. Entitled The Use of Digital Audio Technology in Audio Forensic Investigation the lecture will discuss the need for systems that allow surveillance specialists to combat the effects of noise in non-ideal recording environments. Demonstrations of the uses of single-channel and cross-channel adaptive filters will be given, both independently and when combined with other noise reduction processes. It will be shown how a modern processing system supporting multiple, simultaneous real-time algorithms, can perform complex noise reduction with appropriate processing chains for each job. A demonstration of the abuse of digital audio technology in the forensic arena will also be given, and areas of future research will be proposed.
The IEE Cambridge Branch Committee welcomes visitors - IEE members and non-members alike - to its lectures and other events. For the majority of these there is no charge and no requirement to book in advance. For details about any of the meetings, please contact the Honorary Secretary, Peter Di Mambro at sec@iee-cambridge.org.uk.
Some Historical Information
During World War II (1939-1945) Cambridge University and local industry were engaged in research into radio and radar. To assist in this effort, and following the request of Sir Laurence Bragg (Nobel Prize 1915) the IEE set up a Wireless Section in the city. Many of the early lectures presented by the Wireless Section were far ahead of their time, and included Radio Problems with Cyclotrons (1944), Colour Television (1945), Pulse-Code Modulation and The Computer (1947), Radio Telescopes (1948), The Transistor (1949) and Satellites for Communication (1960).
