Interactive 3D Symphony In VR Space And Its Communication Effects

3D audio could bring brand new immersive experience to the users;it is becoming a very important and unique aspect in Virtual Reality(VR)technologies.And as the concert of vocal or instrumental music,symphony orchestra also have 3D characteristic in the arrangement of music instruments.This paper develops a technology to turn the traditional symphony orchestra into interactive 3D symphony in VR space by arranging the virtual music instruments on a sphere in VR space while the users virtually sit at the center of the sphere;then users could interactively change the sound effects of the symphony by rotating or resizing the sphere,and could also interactively change the position of instruments on the sphere;users could even define their own instruments set to play the interactive 3D symphony,thus achieve superlative music experience.
