- empathetic sound: music or sound effects that match the mood of the action
- sound perspective: the natural change of acoustic properties as sound sources move to and come from different on or off screen locations
- room tone: the background and ambient sound of the scene’s location
When we talk of sound being used to support the narrative, establish character, convey emotions and create or support transition we may mention synchresis, synchronous, asynchronous and foley. Here is what they mean:
- synchresis: the combination of visual image and sound image
- synchronous: sounds that match up with the timing of action
- asynchronous: sounds not synchronised with the action on screen
- foley: post production or live sounds used to reinforce the action on screen
