Abstract

A sound processing method, device and apparatus. The method comprises: acquiring a sound source signal in a set region and image information in the set region (S101); according to the image information, obtaining a coordinate position of the sound source signal in a three-dimensional polar coordinate (S102); according to the coordinate position of the sound source signal, obtaining differential signals of the sound source signal corresponding to each coordinate axis (S103); and acquiring position information about a loudspeaker, and according to the position information about the loudspeaker and the obtained differential signals of each coordinate axis, obtaining a sound output signal of the loudspeaker (S104). Finally, the loudspeaker conducts output according to the obtained sound output signal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a sound signal processing method, device and equipment. Background technique [0002] With the development of communication technology, users can not only use the network for information transmission, but also use the network for voice interaction or video interaction, so users can realize remote communication, such as remote video teaching or remote video conferencing, etc. Wait. [0003] Currently, 3D sound processing is used to process audio streams in audio conferences, that is, by assigning sound image positions to each audio stream, and adjusting the gain of the audio stream in the left and right channels according to the positional relationship of the audio streams at each sound image position size, thereby creating a three-dimensional sound effect. [0004] The current 3D sound processing method is to realize the 3D sound effect of the venue through simpl...
