Immersive Audio Basics
 

  • All traditional cinema Soundfields are in the horizontal plane
  • The layer of loudspeakers that produce traditional cinema Soundfields is called the “Base Layer”

 
Immersive Audio Basics
 
Immersive Sound adds the third dimension of height-sounds above the listener.
 
Why is Immersive Audio so cool?
 
Immersive Sound: Telling the story
 

  • Sound localization, perspective and imaging is in 3D space, enhancing width and depth as well as adding height
  • New possibilities for capturing sounds in nature in 3D and playing them in 3D in the theater
  • Gives the sound designers and mixers a larger space to design, place and move sounds-new ways to tell the story through sound
  • The moviegoer can be made to feel they are in the same space as the action
  • Enveloping the viewer brings more engagement with the story
  • Works well for 2D image, can bring additional life to 3D images

Immersive Sound: Design
 

  • Backgrounds and ambiences-opens up the upper reflections in rooms and the sky in outdoor scenes. Can now design for 3D-bring the listener into the environment. Change with scene cuts. Design for point of view
  • Music-opens up upper reflections, makes the recording room translate more realistically to the theater. Can spread in 3D space like an orchestra or design completely uniquely. Create a virtual soundstage
  • Sound effects-flyovers are more convincing, pass-byes wider, whooshes have more space…room treatments on foley and local effects to bring the listener into the space
  • Dialog-very convincing location treatment. Offstage dialog can be located to POV, PA/radio calls from above. Great use in SciFi as well as drama.
