Difference between a sound editing and sound mixing:
Sound editing is the process of manipulating sounds post-production to receive the desired outcome. This can be to remove background sound or mistakes.

Sound mixing involves mixing individual tracks to create a convincing soundscape. This is done by adjusting levels to create an effect that conveys emotion to enhance the story.

The Shepard Tone – a sound illusion of sine waves separated by octave, with the bass tone ascending in pitch.

Diegetic and non-diegetic sound in Joker:
Diegetic: at 47:10, Arthur dances with his mother, Penny, to the music playing on the television. This ends at 48:08, which is when the show ends.

Non-diegetic: music begins at 31:36, when Arthur is on the train. This continues until 33:20, when it slowly fades out.

Synchronous sound: sound that is matched with the action and movements being viewed.

Asynchronous sound: sound not matched with a visible source of sound on the screen.

Needle drop: when a pre existing song is used in a film to underscore a particular scene. This is powerful as emotions and associations we have with a song can enhance a particular scene. For example, they play Come and Get Your Love by Redbone in Guardians of the Galaxy as the main character, Peter Quill, dances.

Sound effects: artificially created or enhanced sounds – used in artistic works to emphasise or express an action, mood or feeling, e.g. Ben Burtt created the iconic sound for the lightsabres in Star Wars. Sound effects were originally used in radio dramas, but can be observed more often today in podcasts, theatre, films and television shows.

Foley Artist: Adds sound effects post-production by recording in a sound-proof studio and layering it over the top of the scene.

Leitmotif: Musical score that is designed to condition the audience’s emotions towards certain characters. Leitmotif is used for characters, emotion, settings and evolution.

Characters:
Jaws theme tells the audience when the shark is near without explicitly showing it.

Emotion:
Married Life represents Carl’s emotions in Up.

Settings:
There are different themes in Lord of the Rings to suggest where the characters are.

Evolution:
Different versions of the Imperial March are used throughout Star Wars to show the evolution of Darth Vader’s character.

Sound Bridge: When sound carries over a visual transition in a film to bring the viewer seamlessly into the next scene.

Narration: often tells the audience what they need to know, but they can sometimes be unreliable. Unreliable narrators may be lying or not telling the whole story.

Score: the score is music composed specifically for the film to help enhance the mood and themes of the visuals.

Underscore: music that is played under the sequences to enhance mood and support the score – often mixed with dialogue and/or sound effects.

Sound perspective: the apparent distance of a sound source, evidenced by its volume, timbre, and pitch.

My favourite soundtrack is Pulp Fiction because I think the music really fits the general style of the film and helps to convey the emotions of the film.
