Research into Recording Ambient Sounds and Dialogue

An ambient sound recording is a recording of an environment or location that is added to a scene or location. Sometimes you get natural ambient sound, which is known as 'background noise', for example when you are filming outside and you hear the wind.

An example of ambient noise in a film is in The Hunger Games: Catching Fire. They recorded the ambient noise in Maui, Hawaii, for the jungle and ocean scenes. They used stereo pairs when recording the sounds with them pointing away from each other to create a quad-like layout and to make the ambient noise more dynamic.

Hard cuts are ill advised when being used in ambient sound mixing because they're cuts between noises (or shots) with no transition, so the ambient noise would be less realistic and effective - unless it is used specifically for effect or reason - in Catching Fire they use sweeping background noise for affect and anticipation.

The advantage of recording on location and not on sound library is you can get more depth and enhanced sounds, because they are live and you can use multiple microphones to record different layers of sound.




You can have some issues when recording dialogue, because there is a lot to think about - for example you have to work out whether you're going to record straight with the camera microphone, or whether to use dubbing or looping.

Looping is when the actors watch back the recorded clips in a studio, and they re-do the lines as the clip is looped on the screen in front of them, letting them correct and replace the dialogue if it wasn't good enough when recorded on set. Shooting the dialogue on set can be difficult because the ambient noise and other background noise could lessen the quality of the dialogue.

In The Hunger Games: Catching Fire, they used looping because the noise of the waves on the beach scene were so loud they couldn't hear each other talk, therefore looping was the most appropriate solution.
