This document supports the W10 - Rough Cut Screening & Sound Design Production by outlining principles and best practices for gathering and preparing sound materials.
This framework focuses on how sound elements function together within a scene, rather than how to technically edit or mix them.
During this stage you are NOT designing the final sound mix yet. Instead, you are preparing the audio building blocks and understanding how different sound layers interact to support space, action, and narrative.
Think of this stage as building a sound library for your film, not the final soundtrack.
Most films use multiple sound layers working together. Editors build the soundtrack by combining different types of audio that support the visual sequence.
A simple way to understand sound design is to think of it as stacked layers, where each layer contributes a different function to the scene.
A strong sound design usually combines room tone, ambience, Foley, and sound effects, with music used only as an additional layer when appropriate.
Scenes that rely only on music often feel flat or unrealistic, because the viewer cannot hear the environment or physical actions happening in the scene.
By combining multiple layers, filmmakers create a richer and more immersive sound experience for the viewer.
Ambient sound is the background sound of a location or environment.
It helps create a sense of space and continuity between shots.
Examples include:
Ambient sound prevents scenes from feeling unnaturally silent and helps transitions between shots feel smoother.
When working with ambience:
Even very quiet ambience can make a scene feel more realistic and grounded.
Example: At the end of the short film The Jump by Adrian León, an ambient sound layer reinforces the park setting through subtle environmental sounds such as wind, birds chirping, and leaves crunching underfoot.
The character’s footsteps and landing from the jump are likely Foley sounds, added in post-production to match the action, especially since the camera is positioned far from the subject.
Foley refers to custom-recorded sounds that recreate physical actions seen on screen.
These sounds help reinforce the connection between visual movement and sound.
Examples include:
| Visual Action | Possible Foley Sound |
|---|---|
| Walking | footsteps on wood, gravel, or concrete |
| Picking up objects | object contact or movement |
| Clothing movement | fabric rustling |
| Bag interaction | zipper or cloth movement |
Recording tips:
Recording multiple takes helps you select the most natural and convincing sound later.
Example: In Anonymous Gift by Michael Kitka, Foley sound reinforces the character’s physical actions, such as interactions with the box. These sounds are closely synchronized with what we see on screen, making the movements feel more present and grounded.
Ambient sound is also present and gradually intensifies to build tension, providing a subtle background layer that establishes the environment and supports continuity between shots.
Some sounds are difficult or impossible to record directly. In these cases, editors often use Sound Effects (SFX) from sound libraries.
Examples include:
When selecting SFX:
⚠️ Only free, non-copyrighted sounds may be used. Use Freesound.org.
You must record the source information (website, sound title, creator, and license) so it can be credited later in your final project.
| Basic credit format | Example |
|---|---|
| *"Sound Title" by Username — Freesound.org* *License: Creative Commons (CC BY / CC0 / etc.)* *Link: URL* | "Footsteps on gravel" by user123 — Freesound.org License: CC BY 4.0 https://freesound.org/ |
Example: In PAREIDOLIA by Carlos Andrés Reyes, there is a mix of on-screen recorded sound, Foley, and sound effects (SFX). In this excerpt, the alarm is an SFX, while the sound of the hand pumping or forcefully tapping the clock is likely Foley or on-set recording.
The sound of the sleeves moving is most likely SFX, since the fabric appears soft and the sound is exaggerated beyond what would naturally be recorded on set.
The sound of water rushing is likely Foley or on-set recording, as it closely matches the physical interaction and has a natural texture.
Music can be used to reinforce the emotional tone of a scene. However, it should not drive the narrative or replace visual storytelling.
Important guidelines:
(Examples shown may include lyrics for analysis purposes only.)
Music should only enhance the atmosphere, not explain the story.
⚠️ Only your own music or free, non-copyrighted music may be used. Use Freesound.org.

Example: In 2 AM COFFEE by Forrain, the excerpt begins with a subtle ambient layer (room tone) from the outdoor environment, including wind. This is followed by the sound of the doorbell and the door opening, which function as Foley or SFX depending on how they were produced.
As the sequence progresses, music gradually enters and increases in volume, supporting the emotional build-up of the scene. The music reaches its peak at the punchline, when the character realizes the bike is missing, reinforcing the shift in tone.
This opening sequence combines:
These layers are introduced gradually, creating a smooth progression from environment → presence → action → tension.
The film begins with a black screen, but the viewer is immediately placed in the scene through sound. An ambient layer establishes the outdoor environment (street at 2 AM), where we hear wind and a distant car passing by.
Function:
A subtle music layer begins to build in the background, gradually increasing and introducing a light suspense tone.
Function:
As the image appears, a sound effect (low-impact hit / drum-like tone) aligns precisely with the visual transition.
Function:
As the scene continues, the ambient layer remains present while a soft piano element enters the music, maintaining a calm nighttime tone.
At the same time, Foley / on-screen sound of the bike is introduced.
Function:
As the character approaches the store and leaves the bike behind, additional low-impact sounds integrated into the music (bumps or hits) are introduced.
Function:
This middle sequence combines:
These layers shift dynamically, creating a progression from space → interaction → transaction → transition.
The scene takes place inside the mart, where the ambient layer changes from outdoor sound to an interior room tone (subtle hiss).
Function:
The entrance is reinforced by synchronized Foley / SFX sounds, including the doorbell ringing as the door opens, followed by the door closing.
Function:
A music layer (opera with vocals) is present, but it is distant and not fully clear, as if coming from a speaker within the space.
Function:
Note:
Diegetic sound comes from a source within the scene (e.g., radio, speaker), while non-diegetic sound is added for the audience and does not exist in the scene’s world.
As the character interacts with the fridge, we hear Foley / SFX sounds:
The music subtly increases during this action.
Function:
When the camera cuts to an exterior view, the ambient layer shifts back to outdoor sound.
Function:
When the camera returns inside, the music becomes more present, though it still feels like it is coming from a speaker within the space.
At the counter, a series of SFX sounds structure the interaction:
Function:
Notably, the moment when the drink is placed on the counter is paired with the music stopping.
Function:
This final sequence combines:
These layers create a progression from return → anticipation → realization → payoff.
The scene returns to the outdoor environment, where the ambient layer reintroduces the street sound (wind, distant activity).
Function:
We hear the door opening, followed by the doorbell sound, synchronized with the character exiting the store.
Function:
As the character walks away, a music layer begins to fade in, now with a jazzy tone (piano with subtle guitar).
Function:
As the character turns the corner and realizes the bike is missing, the music increases in volume and complexity, introducing drums and saxophone.
Function:
The music maintains this intensity through the end of the sequence.
Function:
