All about Sound effects and Music (soundtrack) creation for game-dev
Vash
Posted on November 13, 2024
Introduction
In this article, I will (have AI) explain the basics of sound and music in game development, and show you applications for creating them using both free and paid tools. The topics include:
- Soundtrack / music creation
- SFX (sound effects) / sound creation
- Ambient sounds / music
I would like to note that besides AI writing the article I have modified most of it myself but used an AI's suggestion(s) as guideline(s). Because, I'm a really really bad writer 😅.
If you spot any mistakes or see a topic or subject that is important but hasn't been talked about or something you would like to know, leave a reaction and I'll look into it.
I would also like to note that the only things you need to create any form of music or SFX are time, a microphone (or pre-sampled sounds), and an application to layer and eventually render/compose all the sounds. (Unless you are working with LPs, but that's another story.)
Music:
- Music is composed of melodies, harmonies, and rhythms.
- It evokes emotions, tells a story, or provides entertainment.
- Often features instruments, vocals, and structured compositions.
- Examples include: background music in films, songs in albums, and instrumental tracks.
SFX (Sound Effects):
- Short, specific audio clips used to enhance actions, environments, or situations.
- Designed to simulate real or imagined sounds.
- Often used to support visual media by adding realism or emphasis.
Ambient Sounds / Music:
- Forms of sound or music used to create atmosphere or set a mood.
- Often low or high-pitched sounds or tracks with a consistent frequency.
Maybe, in the future I will make a seperate article on voice acting / voice-overs and natural sounds (sounds that are made by animals / nature).

Soundtrack / music creation
Soundtrack and music creation are two different things. Both involve making music, but soundtracks are made to fit into movies, games, and other media. This means that they have to be more flexible.
Since this article is for game development, we'll talk about soundtracks and soundtrack creation. However, some tips might also help with regular music creation.
How soundtracks are made
To make a soundtrack for a game, movie, or series, you can follow these steps:
1) Understanding the game/movie/series:
- The composer first needs to fully grasp the story, characters, and atmosphere. This helps in creating music that complements/fits the gameplay and emotions.
2) The concept and theme development:
- Develop a concept or draft for the main themes and motifs. This could be a specific melody or rhythm that represents the game or certain characters.
3) Composing:
- Write or record the music using one of multiple techniques. A few composing techniques will be shown at the bottom of this chapter.
4) Integration with gameplay:
- Syncing the composed soundtracks to the game’s events. This might involve adaptive music that changes based on the player's actions, surroundings, or other specific cues.
5) Testing and tweaking the music:
- One of the most important steps. The music should fit the game’s atmosphere and not be repetitive or negatively impact the player's experience. Modify re-compose your soundtrack/music if necessary.
6) Finalizing:
- If necessary, compose a final piece that replaces the composition from step 3 with a cleaner or higher-resolution version after testing.
Note: The higher the resolution of the audio, the better because you can't upscale audio without any consequenses that lower the quality of the audio.
Composing techniques
Composing is a broad term that includes many different techniques and styles. You can compose music both digitally and manually (analog). The biggest difference is that when composing sounds digitally, you can have a direct preview, while composing manually requires you to play an instrument yourself.
Today, most people use a MIDI (Musical Instrument Digital Interface) controller to sample and play sounds. This is a combination of both hardware and software that allows a composer to make music with an actual instrument and modify it digitally.
When recording analog sounds, you have to either modify the sound itself by tuning your instrument or altering the soundwaves through software solutions.
Like with many other things, you have both free and paid software for all these tasks. The benefit of paid music-creation software is that all the sounds that come with your software are licensed, meaning you can use them however you want. This isn't always the case with free software.
Additional Composing Techniques:
Leitmotif:
- Assign specific themes or motifs to characters, places, or ideas. For example, Darth Vader’s theme in Star Wars.
Layering:
- Build complexity by layering multiple instruments or sounds. Start with a basic melody and add harmonies, rhythms, and effects.
Variation:
- Use variations of a theme to keep the music interesting. This could be changing the rhythm, harmony, or instrumentation.
Orchestration:
- Decide which instruments will play which parts. This can dramatically change the feel of the piece.
Adaptive Music:
- Create music that changes dynamically based on player actions or game events. This involves composing multiple variations and transitions.
Counterpoint:
- Write independent melodies that work together harmoniously. This is often used in classical music.
Improvisation:
- Allow room for spontaneous creation. This is more common in jazz and live performances.
Sound Design:
- Incorporate unique, synthetic sounds created through sound design to add atmosphere and texture.
Recording a Composition
Recording a composition can be done in a few ways. You could:
Make and store a digital composition through different software packages.
Combine both digital and analog recordings and turn it into a digital composition.
Record instruments by playing them yourself or in a (small) group and then stack multiple recordings together to get a final composition.
Record an orchestra playing your composition (this requires a big budget).
Differences between SFX and Sound design (By AI)
Sound Effects (SFX) and sound design are closely related but differ in scope and application. Here’s a breakdown of their differences:
Sound Effects (SFX)
Definition: Sound effects are specific audio clips used to enhance actions, environments, or situations in media such as games, movies, and television. They simulate real or imagined sounds to add realism or emphasis to visual content.
Examples of SFX:
- Footsteps
- Gunshots
- Door creaks
- Explosions
- Animal sounds
Purpose: The primary purpose of SFX is to create a more immersive and believable experience by providing auditory cues that complement the visual elements.
Creation: SFX can be recorded from real-world sources, created digitally, or sourced from sound libraries. They are often short and specific to particular actions or events.
Sound Design
Definition: Sound design is a broader and more holistic process that involves creating the overall soundscape for a piece of media. This includes not only individual sound effects but also the ambiance, mood, and audio aesthetics that support the narrative and emotional impact.
Examples of sound design:
- Designing the unique sounds of an alien environment
- Crafting the audio experience of a haunted house
- Creating the background ambiance of a bustling city
- Developing the sonic identity of a character or creature
Purpose: The purpose of sound design is to shape the auditory experience in a way that enhances storytelling, emotional engagement, and immersion. It considers the entire audio landscape and how various sounds interact and complement each other.
Creation: Sound design involves a combination of recording, synthesis, manipulation, and layering of sounds. It often requires creativity and experimentation to achieve the desired effect. Sound designers use tools like DAWs, virtual instruments, synthesizers, and plug-ins to craft unique sounds.
Summary: while SFX are individual sounds used to enhance specific actions or events, sound design encompasses the entire process of creating a cohesive and immersive audio experience for a piece of media. Both are crucial for making games and other media more engaging and realistic, but sound design goes beyond just effects to include the overall audio atmosphere and aesthetic.
SFX / sound creation / design
Sound effects are crucial in enhancing the immersive experience of a game. They add realism, emphasize actions, and create atmosphere. Here’s a guide to help you understand and create effective sound effects for your game:
How Sound Effects Are Made
To create sound effects for a game, follow these steps:
1. Identifying the Needs
Understand the game’s requirements by identifying where sound effects are necessary. This includes actions, environmental sounds, character movements, and more.
2. Recording or Sourcing Sounds

Zectro is a pretty good youtube chanel for music creation for games.
Venus Thory is a pretty good youtube chanel for music creation for games.
Rocking The Plank: The Music of Sea of Thieves | Inside Xbox is a really good video that shows how the music for a game like Sea of Thieves could be made.
Here is something similar but then for God of War: The Music of God of War with Composer Bear McCreary | Countdown to Launch
The video: ARK Soundtrack: Behind the Scenes is something similar to the one of Sea of Thieves but with a bigger budget and less information on how they did it.
There are many more video's similar to this avalible on YouTube just try to look one up with the following text: "name of the game" + behind the scenes music creation
for SFX creation / recording
As said earlier the difference between SFX and Sound Design is really small. So you could learn very much from both types of work because they are nearly the same.
