Today is the time of 3D video and 4K technology (Quad Full High Definition). However, except the visual shock, how to give more attractions to the works? Do you want to distinct your works from others? There is nothing but 3D sound can meet your requirements. Just imagine the sound effect when helicopter hovering over your head, waves running towards you, lightening flashing your eyes and thunder rumbling right overhead and rain dropping onto your face. These situations can be restored by adopting 3D sound technology. Meanwhile, the 3D hologram sound technology’s accurate localization of every sound can replenish the video with off-screen voice. For example, we can use 3D sound to present a specific invisible scene: one opens the door behind you and steps into the room, followed by a visible one that he appears on the screen. 3D sound can bring a better feeling of presence to video, which is the development trend of the future films.
