FIELD: information technology.
SUBSTANCE: realisation of an apparatus (100) for computing filter coefficients for an adaptive filter (210) for processing a microphone signal so as to suppress an echo due to a loudspeaker signal, which includes an extractor (250) for extracting a stationary component signal or a non-stationary component signal from the loudspeaker signal or from a signal derived from the loudspeaker signal, and a computer (270) for computing the filter coefficients for the adaptive filter (210), which uses the extracted stationary component signal or the extracted non-stationary component signal.
EFFECT: improved sound quality in systems for suppressing or compensating for echo.
