The Application of Psychoacoustic Criteria to the Restoration of Musical Recordings
The paper describes the restoration of musical recordings degraded by additive broadband noise, such as tape hiss, where maintaining fidelity of the underlying musical signal is of primary importance. By integrating psychoacoustics into a restoration process based on perceptual optimality criteria, the authors took advantage of human auditory perception to optimize the compromise between noise reduction and restored signal fidelity.:
