Processing modern audio files to make them appear to have originated from historic technology, called antiquing, is the inverse of restoring old recordings. Simulating both global and local degradations of older technologies can be useful in such applications as testing restoration algorithms. A theoretical analysis of old recordings combined with numerous case studies results in a convincing imitation of historic phonograph and gramophone recordings. This work was motivated by a museum that wanted to show how audio technology has evolved over the last 150 years.
