Dr Chris Hicks, Engineering Director of CEDAR Audio Ltd, will talk about his work in audio restoration and speech enhancement, removing clicks, ticks, scratches, thumps, crackle, buzz, clipping and distortion from audio recordings.

Noise has been the curse of sound recording and transmission systems from the day they were invented. This talk will look at the characteristics of noise, and at why noise contamination of audio signals is so pervasive and so irritating. It will discuss noise reduction techniques, both those that try to avoid the noise in the first place, and those that aim to remove it afterwards. This will include a look at current digital techniques which allow sound and noise to be manipulated and controlled to an unprecedented degree, including live demonstrations using state-of-the-art equipment.
