The Application of Psychoacoustic Criteria to the Restoration of Musical Recordings
Patrick J. Wolfe, Simon Godsill · 2000
We consider the restoration of musical recordings degraded by additive broadband noise such as tape hiss, where maintaining fidelity of the underlying musical signal is of primaxy importance. By integrating psychoacoustics into a restoration process based on perceptual optimality criteria, we take advantage of human auditory perception to optimise the compromise between noise reduction and restored signal fidelity.
