Abstract :
A new method for integrating dynamically steered beamforming filters and acoustic echo cancellation is presented. The proposed method enables beam steering independent AEC processing without parallel AEC filters for each microphone input (a.k.a. AEC-first configuration). Especially for larger microphone arrays the proposed method can provide significant computational savings with comparable performance to AEC-first configuration.
