Interactive audio refers to sound that responds to user actions or choices, creating a dynamic listening experience. This technology is commonly used in video games, virtual reality, and interactive storytelling, allowing users to influence the audio environment based on their decisions or movements. In interactive audio, elements like music, sound effects, and dialogue can change in real-time. For example, in a video game, the background music might intensify during a battle, while in an interactive story, the voiceover may adapt based on the player's choices. This enhances immersion and engagement, making the experience more personalized.
