Research And Planning - Role Research: Sound

As I am being graded on sound and cinematography, I have looked into what these roles actually mean, this is what I have found when researching sound-

I will be in charge of assembling and editing all the sound effects in the trailer as well as ensuring the dialogue, music and effects are all clear and in sync with what is on screen. I will take on a role that (in cinema) is known as The Foley Artist, who is the person who creates many of the ambient or routine sound effects for a film (and in this case, trailer.) I will ensure that all of the sound is appropriate, is varied, can be heard and is of a good standard to ensure that the trailer stays 'sharp' and engaging.
