Abstract

A signal processing apparatus (100) comprising a noise detector (102) configured to: receive a stream of information representative of a stream of audio signal samples (112); and detect samples in the received stream of information (112) that are distorted by impulse noise in order to generate a noise detection signal (114), wherein the noise detection signal (114) also identifies preceding and succeeding samples that are undistorted. The signal processing apparatus (100) also comprises a processor (104) configured to replace distorted samples in the received stream of information with composite predicted values (426; 526) to provide a reconstructed stream of audio signal samples (116).
