Non-contact surface metrology for preservation and sound recovery from mechanical sound recordings
Non-contact surface metrology for preservation and sound recovery from mechanical sound recordings
Optical, non-contact audio recovery methods provide an alternative means for retrieving audio content rather
than risking traditional stylus transfer early sound recordings. The system differs from other optical systems
because the whole surface is scanned, providing a permanent record of the recording’s surface topology,
despite possible further degradation of the artefact. This paper describes the sensing and scanning
methodology, and their implications for the motion control system, and the signal processing techniques for
audio recovery from the surface measurement data. A comparison with stylus transfer is incl

Abstract
Optical, non-contact audio recovery methods provide an alternative means for retrieving audio content rather
than risking traditional stylus transfer early sound recordings. The system differs from other optical systems
because the whole surface is scanned, providing a permanent record of the recording’s surface topology,
despite possible further degradation of the artefact. This paper describes the sensing and scanning
methodology, and their implications for the motion control system, and the signal processing techniques for
audio recovery from the surface measurement data. A comparison with stylus transfer is incl
