Here are the following sound techniques we learnt about:
1. Diegetic - anything that the actors can hear (e.g. radio, cars)
2. Non-diegetic - anything that the actors cannot hear (e.g. voice over)
3. Synchronous - matched with the visible source of the sound on the screen.
4. Asynchronous - not matched with the visible source of the sound on the screen.
5. Sound bridge - blending two scenes together by sound.
6. Ambient - the surrounding sounds that create the atmosphere and creates soundscape.
In the opening of Skyfall a lot of interesting and unique sounds are used throughout. It used Non-diegetic sound throughout as the music is of Adele singing and no sound effects to match the water and the falling, However it still creates an on edge effect immediately as soon as the action and sound is put together.
