Abstract:
1. A method for processing a digital signal, which has been decoded and to which noise reduction post-processing has been applied, to deliver a corrected output signal with reduced distortion introduced by the post-processing, said method comprising the steps of: assigning to the digital signal a current amplitude having an intermediate value between a current amplitude value of the post-processed signal and a corresponding current amplitude value of the decoded signal, or the current amplitude value of the post-processed signal, according to the respective values of the current amplitude of the decoded signal and the current amplitude of the post-processed signal, defining an interval of permitted amplitudes, the interval comprising a lower bound and an upper bound which are dependent on a current amplitude value of the decoded signal, and for a corresponding current amplitude of the post-processed signal, assigning a current amplitude value to the output signal, equal to the value of:
