It has always been said that if you watch a scary film with no sound, even the least fan of jump scares can watch it. This is because sound, although it may not seem like it, is an intrinsic part of our perception of our surroundings. Audiovisual creators know this well and that's why they resort to all sorts of sound effects to emphasise their message or a part of the content.
Not only can they help the viewer to ‘feel more’, but they can guide them through the entire emotional journey of the audiovisual piece and indicate when to be relaxed or tense, for example. Investing in sound means adding realism and emotion to each and every one of your projects. Want to know it all? Keep reading!
What do they consist of?
Sound effects in an audiovisual creation are those sounds, as their name suggests, added to the soundtrack of a film, series, video game, advert, or any other audiovisual medium to enhance the auditory experience and complement the visual narrative. They can be of all kinds, both natural and artificial, and serve to add credibility and ‘texture’ to what we are watching.
It's not the same to see a rider gallop with their horse while hearing the animal's hooves trot, as it is if they don't. Sound effects are what immerse us one layer deeper into the story, hence their importance for:
- Immersion. Sound effects help to immerse the viewer in the world of the story. By adding realistic or contextually appropriate sounds, the viewer feels more connected to what they are seeing, increasing their immersion and emotional engagement.
- Narrative clarity. Sounds help to clarify actions, transitions, and events within a scene. For example, the sound of a car starting can indicate that a character is about to leave, or a doorbell ringing can signal someone's arrival. Without these effects, certain actions or details could go unnoticed.
- The ambience and atmosphere also help to set the tone and mood of a scene. A perfectly chosen soundscape will make a part terrifying, joyful, sad or tense. The simple sound of wind and creaking branches, well accompanied by some aberrant shots, can increase the feeling of unease in a suspenseful scene.
- Emphasis and drama. Sound effects emphasise key moments in a narrative, increasing the emotional impact of certain events. A loud bang sound when a character is punched in the face, for example, can make the violence seem more intense and real.
- Credibility and realism. Although a production may have impressive visuals, without the right sound effects it will appear artificial or incomplete. Everyday sounds, such as the creak of a door or the murmur of a crowd, bring realism and authenticity to the scene and we cannot underestimate their importance. It is these small details that complete an audiovisual piece.
- Brand identity. In advertising or video games, sound effects also help to build a brand identity or a distinctive style. A specific sound can be associated with a product, character, or franchise, making it more memorable for the audience.
- Non-verbal communication. Sound effects can convey information that is not visually displayed, such as a character's mood or the proximity of danger. This allows for richer, more multidimensional communication in audiovisual storytelling.
Sound effects, in the end, enrich the audiovisual experience, making stories more vivid, clear, and emotionally resonant for the viewer. Without them, the narrative would lose much of its power and effectiveness.
Types
There are various types of sound effects in audiovisual creation, each with a specific purpose to enhance the narrative and atmosphere of a production. Let's look at the most popular ones:
Foley effects These are sounds recreated in a studio to imitate sounds heard in real life. Their name comes from Jack Foley, a pioneer in this technique. This is the technique that would be used for the sound of footsteps on a wooden surface, which would be recreated in a studio by recording a person walking on wooden planks.
Environmental effectsAtmosphere): They recreate the environment or atmosphere of a scene. They help to place the viewer in a specific location and establish the tone of the scene. The sound of the wind blowing and the rustling of leaves in a forest would be ambient sound.
Transition effectsStingers): These are sounds used to mark scene changes, indicate a shift in pace, or emphasise a dramatic moment. They can be short and punchy, like a quick drum beat or a rising sound effect when one scene suddenly cuts to another.
Sound DesignSound Design): They are a little more abstract and are often created digitally or by manipulating already recorded sounds. They are used to create unique atmospheres or sounds that do not exist in the real world, such as the sound of a laser in a science fiction film or the roar of a dragon.
Drones and tones They are long, sustained sounds that help create tension or maintain an atmosphere during a scene, like that deep, constant hum you hear during a suspenseful scene.
Impact effects They accompany strong physical or dramatic actions in a scene, such as blows, explosions, or collisions.
Reverberation and echo These effects modify a sound to give the sensation of space or to emphasise its impact in a scene, such as the sound of a voice reverberating in a cave.
Diegetic and extra-diegetic effects The first are sounds that have a visible source within the scene and that the characters can hear (the sound of a phone ringing on a table, which a character hears), while the second are those that do not have a visible source within the scene and that only the viewers can hear, such as background music or a voiceover. Off.
Modulation and alteration These effects involve altering an original sound to change its pitch, speed, or characteristics, creating something new, much like when an actor's voice is sped up or distorted to create the sound of a robotic or alien character.
Response effectsCall and Response): It refers to sounds that interact with actions or dialogue in a scene, such as a call and its response.
All the sound effects we've just discussed are not exclusive, but rather they combine and are used in countless ways to create a rich and immersive audio experience in any audiovisual production.
Remember to plan
In MadMedia What we most like to remember is that any audiovisual project fundamentally consists of and its outcome depends on good prior planning. Without it, we won't get very far in production (and that's We know something. Therefore, the effective integration of sound effects into your audiovisual projects is indispensable, to the point where it can make a big difference in the final quality and impact. So that you get results Brilliant, We’ve prepared a series of basic tips so you can start applying them and see the change:
Plan sound design from the outset. The first piece of advice was very clear, and that is not to leave the sound for the last moment. Many times people fall into the error of thinking that, since the effects are added at a later stage of production, they can be left until then. Think about sound design from the early stages of the project and identify which key moments will require specific sound effects to reinforce the narrative or emotion.
The best thing to do is make a list of those you'll need before starting production so you can record or look for the appropriate effects in good time.
Use sound effects with a purpose. Don't use sound effects just for the sake of filling space. Every effect should have a clear purpose, whether to emphasise an action, establish an atmosphere, or guide the viewer's attention. Therefore, before adding a sound effect, ask yourself how it contributes to the story or the feeling you want to convey.
Play with dynamics and volume. The way you adjust the volume of sound effects in relation to other audio elements (like music or dialogue) can completely change their impact. That’s why we always recommend using volume automation to make certain sound effects stand out or blend smoothly into the background depending on the scene.
Ensure the effects are consistent with the environment.. Sound effects should match the visual environment and action to avoid breaking the viewer's immersion. Pay attention to the details of the space in which the scene takes place (e.g., reverb in a church versus an open space) and adjust the effects accordingly.
Use sound layers to add complexity. Combine multiple sound effects to create a richer and more realistic audio experience. For a gunshot, you can mix the sound of the weapon, the echo, the bullet impact, and the sound of casings falling to the ground for a complete and very realistic effect.
Synchronisation. The synchronisation of sound effects with on-screen action is crucial. A slight delay can make the effect lose impact. Use the timeline of the software editing to adjust sound effects to the exact frame where the action occurs.
Experiment with sound spatialisation. This is responsible for creating the illusion that sound is coming from a specific location, which increases immersion and the viewer's experience. Our advice is to use panning (left/right) and reverberation techniques to simulate the distance and movement of sound in relation to the camera.
Avoid saturation. If you use too few sound effects, the final result will be poor and not very immersive, but if you use too many, you'll end up overwhelming the viewer and detracting from the impact. That's why it's so important to carefully select those that truly add something to the scene and minimise the use of others that could be distracting.
Pay attention to the project flow. The sound flow should always be coherent and natural (unless we are creating a more abstract piece). Abrupt transitions or poorly placed sound effects will break the feeling that what we are seeing is reality. Before considering the sound editing complete, listen to the project from beginning to end and adjust the sound effects to ensure a fluid listening experience.
Try with different devices. Don't forget that we currently live in the era of multiple platforms, so it will be necessary to check how the effects sound on different audio systems, such as headphones, computer speakers, and home cinema systems. Regardless of the device used for playback, the sound effects should be heard clearly and maintain their impact.
