ON THE USE OF VARIABLE LENGTH WINDOWS IN THE RESTORATION OF AUDIO RECORDINGS

O. Cappé

Résumé

The application of spectral substraction methods to the restoration of audio recordings degraded by background noise generally yields satisfactory results. However, these methods introduce some distorsions that can be quite audible in the case of highly degraded recordings. In the first part of the paper it is shown that some of these distorsions are related to the use of a noisy phase spectrum. A solution to the problem of transient signal smearing is then presented. This new procedure makes use of spectral substraction on variable length windows in conjunction with a method for detecting rapid energy variations.
