All-dimension surround sound in the 3D film era

3D movies provided an improved immersion in terms of visual perception. But for the associate movie soundtracks, most of the 3D movies were still produced in the conventional format, such as 5.1 or 7.1 surround format. These conventional surround formats were all insufficient in height information of auditory, inaccuracy of spatial localization as well as lack of immediacy. Many sound professionals and auditory technology companies focused on realizing the audio-visual congruence of 3D movie. In this paper, I would introduce a new auditory concept: ADSS (All Dimensional Surround Sound). By reviewing the history of film sound, I would explore the forming process, theoretical basis, current application and the value of this three-dimensional surround format. With this research, I wanted to raise more filmmakers and film theorists’ awareness of the technological development of film sound and utilize it to make more and more blockbusters for the audience.
