Sound

1. Dubbing is where some sounds that don’t originate from the original material are added in. This is seen often when animes hit US shores, and the mass doesn’t want to watch a subtitled version, hence a US production house dubs over the japanese voices with English speaking ones, and indeed the same idea applies to movies, with foley sound being a notable case of dubbing
2. They are dubbed in on the post production stage, after everything is shot and the films have achieved picture lock usually. This means that the least effort is required, and if it is an anime or similar all that is required is a couple of redrawn frames
3. The sounds would be faded so the viewer can hear what the actors are saying, without the voices being drowned out by the noise of the party for example
4. It seems realistic because it gives context to the surroundings of the characters, without the actual noise of the surroundings of the characters drowning out the characters too much
5. Some sounds might be removed like a siren in the background when the story doesn’t call for a siren, meaning the context can be created and some can be removed to a point. Sounds can be toned down, similarly for a siren, as some can be incredibly loud
6. A mixed soundtrack gives a more professional appeal to the film. If music isn’t mixed, it could vary from mono to surround, which would just sound jarring, therefore a mixed soundtrack removes this problem
7. The sound needs to fit the original mouth movements, therefore it can be dubbed louder or quieter, or something new that fits with the story will be written in order to make the dubbing sound somewhat real
8. The purpose is to make the film accessible to everyone, as too loud or too quiet could alienate different audiences, therefore a cool inbetween is best
1. Fade up/down/in/out -  a technique whereby an image is made to appear or disappear gradually or the volume of sound is gradually increased from, or decreased to zero.
2. Pitch - the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
3. Timbre - the character or quality of a musical sound or voice as a distinct from its pitch and intensity.
4. Acoustic - not having electrical amplification.
5. Perspective - an apparent spatial distribution in perceived sound.
6. Speech - the expression of or ability to express thoughts and feelings by articulate sounds.
10. If the sound continues or there is music, a jump cut isn’t as visible, however when it is empathized the cut becomes very visible. This for example is why Montage scenes aren’t jarrin
11. A sad mood is simply set by either sad music playing in the background or more quiet environment, while happiness can be shown with music or a bouncy dialogue with more busting but not over powerful diegetic sound
12. Heavy metal usually shows sadness, along with blues, while jazz and pop show happiness, and hair metal shows urgency and panic, and punk shows anger
13. It is important that music matches what’s on screen because the viewer needs to be immersed. If it doesn’t the immersion will be broken with the viewer's suspension of disbelief. This only really works in comedies
