Abstract
This article presents a method for restoring audio signals corrupted by
impulsive noise such as clicks, bursts or scratches. The algorithm takes
as input a degraded audio signal and automatically detects the locations
of the degraded samples and replaces them with more appropriate values.
Both steps (detection and interpolation) are based on the assumption
that the signal can locally be modeled as a realization of an
autoregressive process. Surprisingly, the results obtained on several
types of signals (classical, jazz, vocal, etc.) show that a fully
automatic method, with a carefully fixed set of parameters, can achieve
good performance on a wide range of degraded audio signals.
