Generation system and playback system for 3D (three-dimensional) spherical sound multimedia

Abstract

The invention relates to the technical field of multimedia audio processing, and discloses a generation system and a playback system for a 3D (three-dimensional) spherical sound multimedia. The playback system comprises simulation spherical loudspeaker box arrays, wherein the simulation spherical loudspeaker box arrays are arranged on six surfaces of a cuboid, simulate a spherical effect, and comprise a plurality of loudspeaker box groups arranged on the inner surface of the cuboid; each of the loudspeaker box groups forms a horizontal or vertical annular surface, and a plurality of loudspeaker boxes in each of the loudspeaker box groups are distributed on the periphery of the annular surface. According to the generation system and the playback system disclosed by the invention, the effect of a real sound field can be completely simulated by the spherical loudspeaker box arrays, thus realizing a real omnibearing three-dimensional sound effect; a virtual sound image position can be simulated at any position in a viewing space and an environment in a picture can be simulated, thus greatly improving the seeing and hearing experience of field audiences; all conditions for creating an unreal sound effect can also be provided.

Description

technical field [0001] The invention relates to the technical field of multimedia audio processing, in particular to a 3D spherical sound multimedia generation system and playback system. Background technique [0002] In China, where the cultural industry is developing rapidly, the film and television industry, as the core of the cultural industry, is becoming more and more popular among the people. At the same time, related multimedia technologies have also become the focus of technological development. From film to digital, from 2D images to 3D images, from live performances to virtual computer stunts, from high-definition 1080P to IMAX and even to 4K and 5K, the film industry has continuously improved and enhanced its video effects, which undoubtedly brought a new era to the audience. The impact of visual experience again and again has promoted the upgrading of related industrial chains again and again. [0003] But for multimedia technology, the above-mentioned improvem...

Problems solved by technology

Surround sound output is generally only arranged on the circular horizontal plane where the user is located. Although the sound effect surrounding the user is simulated as much as possible, it is still only a simulation in the circular horizontal plane in essence, and the stereo effect in other directions is limited.
