Abstract
Digital signal processing methods to modify sound files to appear aged by imitating historical disturbances are reviewed. The opposite activity, audio restoration, has been cultivated during the past few decades to improve the sound quality of old recordings. Case studies of audio antiquing to render a music file to sound like a phonograph, gramophone, and LP recording are presented.
