Methods for filtering echoes, electronic devices, and computer-readable storage media

Abstract

The invention relates to a method of echo filtering, an electronic device, a computer-readable storage medium, and an echo filtering device. The electronic device consists of M microphones and N loudspeakers. M and N are integers greater than 1. The method consists of the following steps: obtaining N loudspeaker signals corresponding to N loudspeakers (302); obtaining M microphone signals corresponding to M microphones (304); and performing at least direct sound filtering on N loudspeaker signals and M microphone signals to obtain the target signal (306). By using this method, a better echo filtering effect can be achieved.
