FIELD: audio signal processing.
SUBSTANCE: disclosed is a signal processor for providing one or more processed audio signals (
(n); 
(n)) based on one or more input audio signals (y(n)), wherein the signal processor is configured to estimate the coefficients (
(n)) of the autoregressive reverberation model using one or more input audio signals and one or more delayed reverberating signals with noise suppression (
(n)), obtained using noise reduction; and wherein the signal processor is configured to provide one or more noise-suppressed reverberating signals ((n)) using the input audio signal and the autoregressive reverberation model estimated coefficients ((n)); and wherein the signal processor is configured to produce one or more noise-suppressed and reverberation-suppressed output signals ((n); (n)) using one or more reverberating signals with suppressed noise ((n)) and estimated coefficients ((n)) of the autoregressive model of reverberation.
EFFECT: providing noise suppression and reverberation suppression for audio signals.
