Sound in film making

To begin with I'm going to talk about the layers of sound track that you will hear in a film or in other media forms.
SYNC sound is the sound that records with the footage as you are filming it using an microphone that has been built in or an attachment, so that when you upload it on to your editing software  you don't ten have to try and sync all sound with the track. If the sound is out of sync you will lose the illusion of the film and you would lose money because the audience could not stand hearing the sound before or after the event has happened instead of hearing it at the same time of the event. This also makes it easier to add different layers of sound on top of the original soundtrack track, for example adding sound effects for a fight scene because you already have the sound there you just need to move the effect on top of it and delete the original clip  instead of looking for where to place it and lining it up correctly so it feels looks and sound natural.

ADR otherwise known as Additional Dialogue Recording or dubbing is used to change the language, to add a quiet voice which you could not here or just to replace the original voices with a more crisp voice, as an example in a film where there are guns shooting and a character is talking at a normal level across a room to another character. in realty you could not hear his voice but in the film you can hear it easily over the added sound effects because they have dubbed over his voice from the footage with his voice form a recording they did in a studio. The big problem with this is if what they are saying dos not match with their lips the audience will notice and will lose the illusion of the film, and this happens allot when you change the language of the film.

ATMOS is the sound that sets the scene, like the establishing shot its used to tell you where the characters are and what is happening, without it you the film would leave you displaced momentarily as it changes the place and.

Foley Sound is recreating live sounds from the production and then adding them so you have a more nice and crisp sound instead of the SYNC sound that was recorded with the footage. As an example in a film when you listen to a dog run across a road from afar the sound you would hear is coming from a sounds make after the the footage was filmed so Foley artists could recreate the sound in sync with the dogs paws tapping against the pavement. To do this they would use pepper clips for the claws and some padded leather for the paws in order to recreate the sound.

Sound Effects is for any sound added during the post-production/ editing, this means all the sound types of sound that i have talked about apart from SYNC is SFX or sound effects.

Music Is used to try to create an emotional response from the audience, for example they would play a slow by slightly dramatic song or for and action scene they would play a fast beet song. or it can to be used to push a film forward at the beginning of a new chapter, where there is little speech. as an example in Reservoir Dogs beginning  scene they just had the main charters walking after a little narration and that helped move the film on to another scene and set a vibe for the film.
