Sound design for film

• A. Non-diegetic sound
• B. Diegetic sound ✓
• C. Foley
• D. Ambient drone

Why: Diegetic sound comes from within the story world, such as dialogue spoken by characters or music played on a radio in a scene. Non-diegetic sound, by contrast, comes from outside the story world, such as a film score added in post-production.

• A. The recording of live orchestral music during filming
• B. The creation and recording of everyday sound effects performed in sync with the picture ✓
• C. The mixing of dialogue tracks to a consistent loudness level
• D. The use of synthesized tones to represent emotional states

Why: Foley is named after Jack Foley, a pioneer of the technique. Artists recreate everyday sounds such as footsteps, cloth rustling, and object handling in a studio, synchronized to the on-screen action, to enhance realism.

• A. Sync sound
• B. Stinger
• C. Ambience ✓
• D. Leitmotif

Why: Ambience (or atmosphere) is the continuous background sound that establishes the environment. It helps make a location feel real and is often layered beneath dialogue and effects.

• A. To add reverb to dialogue recorded in a studio
• B. To fill silent gaps and maintain a consistent background sound when edited dialogue has no natural background ✓
• C. To tune the pitch of musical instruments in the score
• D. To measure the acoustic properties of a filming location

Why: Room tone is a recording of the silence of a location. Editors use it to fill gaps created by cutting dialogue, so the background noise does not abruptly disappear and draw attention to the edit.

• A. Sound that has been digitally synthesized to match the musical tempo
• B. Audio recorded simultaneously with the picture so that it lines up with the on-screen action ✓
• C. Sound effects added to a film after it has been color graded
• D. A mixing technique that balances all audio channels to equal volume

Why: Sync sound is audio captured during filming, such as dialogue recorded on set with the camera running. It stays aligned with the image, as opposed to sounds added later in post-production.

• A. To create the final mixed soundtrack for the film
• B. To capture clean dialogue and on-set audio for use in the edit ✓
• C. To record music that will be played during filming
• D. To generate sound effects for post-production only

Why: Production sound captures the dialogue and ambient audio recorded during filming, which editors and sound designers use as the foundation for the final dialogue track, even though it is often supplemented with ADR or Foley later.

• A. Shotgun microphone mounted on a boom
• B. Lavalier (lapel) microphone ✓
• C. Large diaphragm studio condenser on a stand
• D. Dynamic handheld microphone

Why: Lavalier microphones are small, clip onto clothing, and can be placed close to the actor's mouth out of frame, making them ideal when a boom cannot be positioned unobtrusively.

• A. The reverberation added to dialogue in post-production
• B. The ambient sound of a location recorded with no dialogue or action ✓
• C. The tonal quality of the room's acoustic treatment
• D. The pitch of the sound engineer's voice when giving cues

Why: Room tone is recorded silence, or the natural ambience of a space, captured for several seconds or longer after a scene. Editors use it to fill gaps and smooth transitions between cuts.

• A. Higher levels reduce the need for microphones
• B. Digital clipping causes irreversible distortion when audio exceeds the maximum level ✓
• C. Quieter recordings always sound more professional
• D. It prevents the camera from overheating

Why: In digital recording, anything above 0 dBFS is clipped and cannot be recovered, producing harsh distortion. Engineers typically aim for peaks around -12 to -6 dBFS to leave headroom.

• A. To signal the actors when to begin performing
• B. To provide a sync reference point and identify the scene and take for the editor ✓
• C. To indicate the lighting setup for the camera operator
• D. To measure the distance between the actor and the microphone

Why: The slate's audible clap provides a sharp transient that aligns picture and sound during syncing, while the written information labels the take so editors can organize footage efficiently.

• A. To add music under every scene
• B. To create clean, intelligible, and consistent dialogue tracks that match the picture ✓
• C. To replace all actors' voices with voiceover
• D. To remove all background ambience from the film

Why: Dialogue editing focuses on making spoken lines clear, consistent in tone and level, and synchronized with the picture so the audience can follow the story without distraction.

• A. Audio Digital Recording
• B. Automated Dialogue Replacement ✓
• C. Advanced Dynamic Range
• D. Ambient Dialogue Reduction

Why: ADR, or Automated Dialogue Replacement (also called looping), is the process of re-recording dialogue in a studio when the original production audio is unusable due to noise or other issues.

• A. Reverb plugin
• B. Chorus effect
• C. Noise reduction or a notch filter ✓
• D. Pitch shifter

Why: Noise reduction processors and notch filters target steady, repetitive sounds like hum, allowing editors to remove them while preserving the dialogue's natural character.

• A. To record the actor's breathing for lip sync
• B. To capture the ambient sound of a location without dialogue, used to fill gaps and smooth edits ✓
• C. To record music cues for the scene
• D. To measure the reverb time of a studio

Why: Room tone is a few minutes of silence recorded at each location. It is used to fill gaps between edited dialogue so that cuts do not sound unnaturally silent or jarring.

• A. It makes the dialogue louder
• B. It adds reverb to the voice
• C. It smooths the transition between clips so edits are inaudible ✓
• D. It changes the actor's pitch

Why: Crossfades overlap the end of one clip with the start of another, gradually blending the sound. This creates seamless edits that avoid clicks, pops, or abrupt changes in background sound.

• A. The digital synthesis of sci-fi sound effects
• B. The recreation of everyday sounds performed in sync with the picture, such as footsteps and cloth movement ✓
• C. The mixing of dialogue and music into a final soundtrack
• D. The recording of live orchestral scores for a film

Why: Foley is named after Jack Foley and refers to the live performance and recording of everyday sound effects, like footsteps, rustling clothing, and prop handling, synchronized to the on-screen action.

• A. Because the real materials are too expensive to use on set
• B. Because the real-world sound of an action is often unconvincing or inaudible when recorded, while a substitute can sound more vivid and believable ✓
• C. Because the studio prohibits the use of real props
• D. Because these objects are required by union rules

Why: Real-world sounds do not always translate well to microphones or the cinema experience. Foley artists choose substitutes that deliver the emotional impact and clarity the audience expects.

• A. Carpet only
• B. Metal sheets only
• C. A pit containing different materials such as gravel, wood, tile, and concrete ✓
• D. Plain glass

Why: Foley pits hold a variety of surfaces so the artist can perform footsteps on the material matching the character's on-screen location, such as gravel for a driveway or wood for a floor.

• A. To lower the volume of the sound so it matches the music
• B. To align the timing of the recorded sound precisely with the corresponding on-screen movement ✓
• C. To convert the sound into a different audio format
• D. To add reverb so the sound fits the room

Why: Syncing means matching the timing of each recorded sound precisely to the visual action, so that footsteps land on each step and a door creak coincides with the door moving.

• A. A wide-angle room microphone placed across the studio
• B. A close-miking setup with a directional microphone placed near the sound source ✓
• C. A telephone handset
• D. A speaker placed in the booth to play back sound

Why: Close-miking with a directional microphone captures the detail of the sound source while rejecting unwanted room noise, producing clean and isolated effects for the mix.

• A. To replace all dialogue with music
• B. To establish the sense of place and environment around the characters ✓
• C. To make the sound mix louder overall
• D. To cover up mistakes made during editing

Why: Ambience (also called atmosphere or room tone) gives the audience a sense of location and environment, such as the hum of a city street or the chirping of insects in a forest, making the scene feel real and grounded.

• A. The reverb added to dialogue in post-production
• B. The natural background sound of a location recorded when no one is speaking ✓
• C. A musical note tuned to match the room's key
• D. The sound made by audio equipment inside a studio

Why: Room tone is the characteristic background sound of a space, recorded during silence on set. Editors use it to fill gaps and smooth transitions so that cuts between dialogue do not sound abrupt or artificially silent.

• A. A single sustained synthesizer pad
• B. Layered traffic, distant sirens, crowd murmur, and footsteps ✓
• C. Only a silent track with no sound
• D. A solo piano playing a slow melody

Why: A convincing city soundscape is built from multiple layered elements such as traffic, distant sirens, crowd chatter, and footsteps. Layering these sounds creates depth and realism that a single sound cannot achieve.

• A. Because ambience is always louder than dialogue
• B. Because subtle, unsettling background sounds can create unease even when nothing visible happens ✓
• C. Because the audience cannot hear ambience clearly
• D. Because tension is always created with music alone

Why: Subtle ambient sounds, such as a low drone, a faint creak, or an unnatural hush, can make audiences feel uneasy without any visual cue. This makes ambience a powerful tool for building suspense and atmosphere.

• A. To lower its volume gradually over time
• B. To move the sound's position between speakers to suggest direction or movement in space ✓
• C. To remove all high frequencies from the sound
• D. To loop the sound endlessly without variation

Why: Panning moves a sound between speakers, such as left to right or front to rear in a surround system. This helps place sounds spatially, for example making a passing train seem to travel across the screen.

• A. To increase the overall loudness of the film
• B. To keep dialogue intelligible by lowering the music when speech occurs ✓
• C. To remove the musical score entirely from quiet scenes
• D. To match the tempo of the music to the actors' speaking speed

Why: Ducking temporarily lowers music or effects levels when dialogue is present so that the spoken words remain clear and easy for the audience to follow.

• A. Non-diegetic music
• B. Diegetic music ✓
• C. Underscore
• D. Stinger

Why: Diegetic music originates from a source within the story's world and can be heard by the characters, whereas non-diegetic music is added for the audience only.

• A. A single sound effect recorded in isolation
• B. A grouped submix of related elements such as dialogue, music, or effects ✓
• C. The metadata tag attached to an audio file
• D. The fade-out at the end of a cue

Why: Stems are grouped submixes that combine related tracks, such as all dialogue, all music, or all effects, allowing easier balancing and delivery in multiple formats.

• A. To add more bass energy to the score
• B. To remove low-frequency content that clutters the space needed by voices ✓
• C. To make the music louder without changing its volume
• D. To convert the music into mono

Why: Removing low frequencies from music reduces masking of the dialogue's fundamental range, helping voices stand out clearly in the mix.

• A. A long, sustained orchestral swell that opens a film
• B. A short musical accent timed to a specific visual moment, such as a jump scare or reveal ✓
• C. A recording error caused by clipping the microphone
• D. A background ambience loop used in outdoor scenes

Why: A stinger is a brief, punchy musical hit synchronized to a sudden visual event, emphasizing surprise, humor, or a dramatic turn.

• A. -6 LUFS
• B. -24 LKFS (dialogue-gated, per Dolby/ITU guidance for cinema) ✓
• C. -14 LUFS
• D. 0 dBFS peak

Why: Theatrical film mixes are typically referenced to around -24 LKFS integrated loudness (dialogue-gated), which aligns with cinema playback standards and leaves headroom for dynamic range. The other values are targets for streaming, broadcast, or are not loudness standards at all.

• A. Music and Effects ✓
• B. Mix and Edit
• C. Master and Export
• D. Monitor and Estimate

Why: M&E means Music and Effects: a mix containing everything except dialogue, used so that foreign-language dubbing and audio description can be added later. It is a standard deliverable for international distribution.

• A. 0 dBTP
• B. -1 dBTP ✓
• C. +3 dBTP
• D. -20 dBTP

Why: A true peak limit around -1 dBTP is widely used to leave room for inter-sample peaks that appear during digital-to-analog conversion or lossy encoding. Setting the ceiling at 0 dBTP risks clipping after encoding.

• A. Stereo files are required by copyright law
• B. Many playback systems and platforms only support two channels, so a compatible downmix ensures the content translates correctly ✓
• C. Surround channels cannot be encoded digitally
• D. The LFE channel must be removed for stereo listening

Why: Not every playback environment supports multichannel audio, such as laptops, earbuds, and some TV setups. A carefully checked stereo downmix preserves dialogue clarity and balance for those listeners.

• A. To list the actors' contracts
• B. To verify that format, naming, channel layout, loudness, and metadata meet the distributor's specifications before handoff ✓
• C. To schedule the composer's recording sessions
• D. To set the reverb times for each room

Why: A delivery checklist confirms technical compliance with the distributor's requirements, such as file format, sample rate, bit depth, channel configuration, loudness, and labeling. Catching errors here prevents costly rejections later.
