Sound design in video games is undoubtedly the field that most fully harnesses the interactive nature of the discipline.
Every effort is made to maximize the player’s experience by adapting the soundscape to the player’s actions and the context in which they are playing.
The concept of sound identity is very much present, as it ensures that the game’s soundscape accurately embodies the intended vision.

The most distinctive feature of sound in video games is that it is nonlinear.
It constantly evolves and adapts to the player’s progress, which makes it absolutely unique. Control over it therefore lies with the player, not the composer.

To ensure an optimal listening experience, it is therefore necessary to anticipate every possibility by analyzing the relative importance of each sound, how often it will be played, and the context in which it will occur.

Finally, it’s important to address one of the most significant aspects of video games: repetition. Your ears get tired—and quickly!
There are two specific ways to counteract auditory fatigue caused by the repetition of the same sound:

• Recording the same sound effect multiple times. From a physical standpoint, no two sounds are exactly alike—even with the best of intentions. Recording multiple takes of the same sound effect doesn’t take much longer, and it greatly enhances the audio experience.
• The real-time, random modification of parameters and audio segments played by the game engine or sound engine. This is exactly the technique used to create adaptive music (music whose instrumentation and rhythm vary depending on the character’s actions in the game).
