Digital Audio Antiquing - Signal Processing Methods for Imitating the Sound Quality of Historical Recordings

Abstract

Digital signal processing methods are proposed that will modify sound files to appear aged by imitating historical disturbances. The opposite activity-audio restoration-which will improve the sound quality of old recordings, has been cultivated for the past few decades. Case studies of audio antiquing, rendering music files to sound like a phonograph, gramophone or LP recording, are presented.
