Abstract
An echo filtering method, an electronic device, a computer-readable storage medium, and an echo filtering apparatus are disclosed. The electronic device includes M microphones and N speakers. M and N are integers greater than 1. The method includes: obtaining N speaker signals corresponding to the N speakers; obtaining M microphone signals corresponding to the M microphones; and performing at least direct sound filtering on the N speaker signals and the M microphone signals to obtain a target signal. By using this method, better echo filtering effect can be obtained.
