Thesis "Music visualiser for virtual reality" deals with theoretical basis of developing mobile app and the actual development. The theoretical basis describes the definition and interpretation technology for virtual reality. Further discussion of software and hardware used to implement the application. Also examining the principles of sound signal and music visualization and then designing the app. The practical part describes how to create 3D environment and how to transfer it into the environment SceneKit framework. Consequently, the principles of which were used for programming the response of the 3D scene to playing music via head movement of the user, testing and optimization
