Echo suppression comprising modeling of late reverberation components |
| abstract |
An apparatus (200) for computing filter coefficients (H[k,m]) for an adaptive filter (210) is disclosed. The adaptive filter is used for filtering a microphone signal (140, 430) so as to suppress an echo due to a loudspeaker signal (130, 420). The apparatus (200) comprises: an echo decay modeling means (465) for modeling a decay behavior of an acoustic environment (120) and for providing a corresponding echo decay parameter (τ; α m ); and computing means (270; 370) for computing the filter coefficients (H[k,m]) of the adaptive filter (210) on the basis of the echo decay parameter (τ; α m ). A corresponding method comprises: providing echo decay parameters (τ; Ĝ[k,m]; α m ) determined by means of an echo decay modeling means (465); and computing the filter coefficients (H[k,m]) of the adaptive filter (210) on the basis of the echo decay parameters (τ; α m ). |
