DESCRIPTION:This year marks the 25th anniversary of CEDAR Audio Ltd. openi
 ng for business. CEDAR was amongst the earliest of the recent wave of 'spi
 n-out' companies from the University of Cambridge\, and was set up \nfollo
 wing a research project in the Engineering Department funded by the \nNati
 onal Sound Archive of the British Library. \n\nThe initial focus was to us
 e digital signal processing techniques to remove the surface noise that re
 sults from fungal decay of shellac- and cellulose- based audio discs.\n \
 nOnce CEDAR was founded\, the scope soon expanded to include a wide range 
 of noise reduction processes applicable to many recording media\, and then
  further to tackle noise and interference inherent in the audio \nsignals 
 themselves\, not just noise added by the recording medium. \n\nSince its i
 nception\, CEDAR has been at the forefront of noise reduction in a commerc
 ial\, professional audio context\, with applications and clients in \nthe 
 music\, film & TV\, broadcast and security industries.\n \nThis lecture w
 ill look at the technological landscape that enabled CEDAR \nUnderpinned i
 ts success\, and use live demonstrations to illustrate the \ntechnologies 
 developed by CEDAR over two and a half decades. \n\nThere will be an empha
 sis on current techniques and a look forward to some of the major remainin
 g unsolved problems.
