Abstract
Official abstract text for this publication.
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 ).
