Sound editing involves the assembly and sometimes creation of sound recording to produce a final sound mix for a film.
A sound editor is different to a designer because they focus more on assembling the sounds together rather than initially creating original sound.
Notable sound editors include:
Richard King – won Academy awards for his work on Dunkirk (2017) Inception (2010) directed by Christopher Nolan
Paul N.J Ottosson – won two academy awards for his sound editing on The Hurt Locker (2008) and Zero Dark Thirty (2012) both directed by Kathryn Bigelow
