Abstract
A sound effect adjustment method is provided. In the method, a video frame and an audio signal of a corresponding time unit of a target video are obtained. A sound source orientation and a sound source distance of a sound source object in the video frame are determined. Scene information corresponding to the video frame is determined. The audio signal is filtered based on the sound source orientation and the sound source distance. An echo coefficient is determined according to the scene information. Further, an adjusted audio signal with an adjusted sound effect is generated based on the filtered audio signal and the echo coefficient.
