Abstract
The present invention discloses a sound processing method and apparatus. The method is applied to a non-video-call scenario. The method includes: when it is detected that a camera of a terminal is in a shooting state, collecting a sound signal by using the two microphones at the top of the terminal; calculating an interaural level difference between the two microphones based on collected sound signals according to a preset first algorithm; determining whether the interaural level difference meets a sound source direction determining condition; if the determining condition is met, determining, based on the interaural level difference, whether the sound signal includes a rear sound signal, where the rear sound signal is a sound signal whose sound source is located behind the camera; and if it is determined that the sound signal includes a rear sound signal, filtering out the rear sound signal from the sound signal.
