Digital Audio Antiquing - Signal Processing Methods for Imitating the Sound Quality of Historical Recordings
Vesa Välimäki, Sira González, Ossi Kimmelma, Jukka Parviainen · Journal of the Audio Engineering Society · 2008
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.
