Abstract
Systems, methods, apparatus, and computer-readable media for dereverberation of a multimicrophone signal combine use of a directionally selective processing operation (e.g., beamforming) with an inverse filter trained on a separated reverberation estimate that is obtained using a decorrelation operation (e.g., a blind source separation operation).
