Abstract

A signal processor comprising: an input terminal, configured to receive an input-signal; a voicing-terminal, configured to receive a voicing-signal representative of a voiced speech component of the input-signal; an output terminal; a delay block, configured to receive the input-signal and provide a filter-input-signal as a delayed representation of the input-signal; a filter block, configured to: receive the filter-input-signal; and provide a noise-estimate-signal by filtering the filter-input-signal; a combiner block, configured to: receive a combiner-input-signal representative of the input-signal; receive the noise-estimate-signal; and combine the combiner-input-signal with the noise-estimate-signal to provide an output-signal to the output terminal; and a filter-control-block, configured to: receive the voicing-signal; receive signalling representative of the input-signal; and set filter coefficients of the filter block in accordance with the voicing-signal and the input-signal.
