A 3D virtual immersive panoramic sound recording system

Abstract

The invention relates to a 3D virtual immersion panoramic sound recording system. The 3D virtual immersion panoramic sound recording system comprises a network machine room, a central machine room, a projection machine room and a sound mixing recording studio; a central storage device is arranged in the network machine room; an audio-video working station, a time clock synchronous system, a digital optical fiber transmission system and a high definition analog-digital / digital-analog converter are arranged in the central machine room; a movie theatre processor, an audio frequency switching matrix and a power amplifier are arranged in the projection machine room; a silver screen and a plurality of loudspeaker sound boxes are arranged in the mixing sound recording studio; the plurality of loudspeaker sound boxes comprise a plurality of main loudspeaker sound boxes, a plurality of bass loudspeaker sound boxes, a plurality of upper layer pre-loudspeaker sound boxes, a plurality of lower layer pre-amplifier sound boxes, a plurality of upper layer stereo loudspeaker sound boxes, a plurality of lower layer stereo loudspeaker sound boxes, a plurality of top stereo loudspeaker sound boxes and a plurality of vertex angle loudspeaker sound boxes. The 3D virtual immersion panoramic sound recording system has beneficial effects that the 3D virtual immersion panoramic sound recording system is easy in installation, high in manufacture efficiency, and low in cost, and can manufacture multiple sound systems.

Description

technical field [0001] The invention relates to a 3D virtual immersive panoramic sound recording system. Background technique [0002] Human exploration of the concept of "surround sound" can be traced back to 1550. At that time, European hymns were popular. Composers grouped the chorus by voice parts, and staggered the positions according to the shape of the church in order to make the audience clearer. Hear the melody going to the harmony part level. By the end of the 1790s, movies were born, but they were presented silently for a long period of time, and people even tried to make the voice actors stand behind the screen to speak to vividly picture the content. [0003] In 1910, Edison invented the sound film machine, and the sound and picture could finally be recorded and played back at the same time. In the movie "Jazz Singer" released in 1927, the audience suddenly heard the protagonist say: "Wait a minute, wait a minute, what are you waiting for?" I haven't heard of ...

AI Technical Summary

Problems solved by technology

For example, in the current mainstream multi-channel system, there are fewer speakers to reshape the sound field environment, the transition of sound between channels is unnatural, the separation of surround sound is not enough, and the system's ability to deal with different equalization for multiple channels is not strong , the low-frequency response of the 0.1 channel is not smooth enough, the best listening area is narrow, etc. These problems greatly reduce the authenticity of sound reproduction

The most important thing is that the existing multi-channel system can only play back the sound in two-dimensional space, and lacks the sound in the vertical direction such as above the head, which prevents the listener from being immersed in the scene of the movie.
